Creating a marketing portfolio: tips and examples
Jul 05, 2024
By Peter Esiet | Digital Marketer, Business Strategist and Digital Wealth Creator
If there is one thing I have learnt from working in digital marketing, it is this: you do not need to own a big company, have millions of followers, or be an expert in every digital skill before you can start making money online.
You need to understand how businesses make money, identify what people will pay for, and connect the right products or services with the right audience.
That is the real opportunity in digital marketing.
I have built my approach around a simple principle: attention is valuable, but attention that produces sales is even more valuable.
Businesses need customers. Professionals want to sell their expertise. Course creators want more students. Companies want people who can explain their products, generate leads, build trust, and convert potential customers into paying clients.
This creates opportunities for people who understand digital marketing.
In my own journey, I have discovered several ways to make money online. I create and sell courses in areas I understand. I also promote courses created by other people when I identify high-demand skills and a market for them. I generate leads for businesses, help companies promote their products and brands, and host webinars where I educate potential customers on behalf of businesses.
These are not just ideas I am sharing for the sake of writing an article. They are methods I use to approach online income and business growth.
In this article, I will explain how these methods work, how you can start using them, and other opportunities worth exploring if you want to become a digital marketer.
Digital marketing is the use of digital channels, platforms, content, data, and technology to attract potential customers, promote products or services, generate leads, and increase sales.
These channels include search engines, social media, websites, email, online advertising, video platforms, webinars, and messaging applications.
Digital marketing is not limited to posting on Facebook or Instagram. It includes several specialised skills, such as:
The reason I consider digital marketing an attractive career is that businesses can use these skills to solve real commercial problems.
A real estate company may need qualified buyers. A school may need more students. A software company may need product demonstrations booked. A course creator may need more sales. A new business may need visibility and credibility.
When you can solve one of these problems, you have something you can sell.
You can work as a freelancer, consultant, employee, agency owner, affiliate marketer, content creator, or digital entrepreneur.
Demand also has measurable indicators. In its September 2025 hiring report, Upwork reported that digital marketing contracts on its marketplace grew by 9%, while SEO and search engine marketing among small and medium-sized businesses grew by 8% and 7%, respectively. The report also stated that 53% of surveyed businesses anticipated hiring freelance digital marketers in the following three months.
These figures describe a particular freelance marketplace and survey period, not every business or the entire global economy. However, they illustrate that businesses continue to seek digital marketing expertise.

The question, therefore, is not simply whether you can learn digital marketing. It is whether you can turn what you learn into a service, product, or business that people are willing to pay for.
Here are the methods I use and the additional opportunities you can explore.
One of my preferred ways of making money online is by turning my knowledge into digital products.
I believe that if you have spent time learning a valuable skill, solving a problem, or gaining experience in a particular field, you should consider packaging that knowledge into something other people can buy.
For example, I have experience in digital marketing, business development, content marketing, and business growth. Rather than relying exclusively on clients to pay me for individual services, I can organise what I know into structured lessons and sell them to people who want to acquire those skills.
This is one reason I work with platforms such as Selar, where creators can sell online courses and other digital products.
The principle is straightforward: learn a valuable skill, organise your knowledge, create a product that solves a specific problem, and market it to the people who need it.
Do not begin by asking, “What course can I create?”
Ask, “What problem can I help someone solve?”
For example:
A course becomes easier to market when its intended audience and practical outcome are clear.
Research what people are searching for, the questions they ask on social media, the courses competitors sell, and the problems businesses are trying to solve.
Speak to potential students. Publish educational content. Offer a free training session or a small paid workshop to test interest.
Do not assume that a topic will sell merely because it interests you.
You do not need a sophisticated studio to begin.
You can record lessons using a smartphone, a computer screen recorder, a microphone, and simple editing software.
Organise your course into modules, demonstrations, exercises, templates, and assignments. Teach people how to do something, not merely what it means.
For instance, a digital marketing course could guide students through creating a landing page, setting up a campaign, tracking leads, and analysing results.
Create a seller account on Selar, prepare your product page, upload your learning materials, set your price, and configure your payment and delivery arrangements.
Selar’s official documentation describes support for courses, downloadable products, subscriptions, services, and other digital products. Its features can help creators sell without having to build a complete e-commerce system from scratch.
See Selar’s guide to selling products and services.
Creating the course is only part of the work. People must discover it and understand why they need it.
You can market it through:
For example, if I create a course on digital marketing with AI, I can publish content about how businesses use AI to create content, automate lead follow-up, improve campaign workflows, and analyse marketing performance. I can then direct interested readers to a page explaining the course and how to enrol.
The content attracts attention; the course page explains the offer; and the checkout enables the purchase.
Let us use a simple illustration.
Suppose you create a practical course and sell it for ₦20,000.
These figures are calculations, not a promise that you will achieve those sales. Your actual earnings depend on demand, pricing, trust, marketing costs, platform fees, refunds, taxes, and the quality of your product.
The important advantage is that a recorded course can be sold repeatedly without requiring you to teach every student individually.
That does not mean the income is completely passive. You still need to attract customers, answer questions, update materials, and maintain the quality of the learning experience.
Nevertheless, this model allows you to turn knowledge into a product that can serve more people than your time alone would permit.
Here is another method I use: I do not restrict myself to selling only courses I create.
Sometimes, I discover a skill that is attracting significant interest, but I do not have enough knowledge or experience to teach it myself.
Rather than pretending to be an expert, I look at the commercial opportunity.
If people want to learn a skill, businesses need that skill, and a credible creator has developed a good course around it, there may be an opportunity to promote and sell that course.
This is where affiliate marketing and authorised course reselling come in.
The distinction matters.
With affiliate marketing, the course creator or merchant allows you to promote a product using a unique tracking link and pays you a commission on qualifying sales.
With reselling, you must have the appropriate rights to resell the product under the agreed terms. Buying a course does not automatically give you permission to redistribute its content or claim it as your own.
I focus on the commercial opportunity while respecting the knowledge and intellectual property of the original creator.
Look for topics where people are actively seeking training and where acquiring the skill can solve a meaningful problem.
Examples include:
These are research starting points, not a guarantee that every course in these categories will sell.
Look for evidence: relevant search interest, recurring questions, active communities, employer requirements, competitor offerings, and signs that people are paying for training.
Evaluate the course before promoting it.
Review the curriculum, instructor’s experience, student feedback where available, practical assignments, support arrangements, and the relevance of the material.
A popular topic cannot compensate for a poor-quality course.
Contact the creator or check their affiliate programme.
Clarify the commission rate, payment terms, refund policy, permitted promotional methods, use of course materials, and how sales are tracked.
Some platforms, including Selar, provide affiliate marketing options. You can learn more through the Selar affiliate programme.
Do not simply post an affiliate link and expect people to buy.
Create content that answers the questions potential students have before making a decision.
For example, if I am promoting an AI automation course, I could create content explaining what an AI automation specialist does, which business processes can be automated, what tools beginners can learn, and what kinds of projects demonstrate practical competence.
I can then recommend the course to people who want structured training.
I should also explain that I am promoting someone else’s course where that relationship is relevant, rather than implying that I personally created or teach it.
Measure clicks, leads, conversions, refunds, and commission earned.
If a campaign generates attention but no sales, investigate the problem. Perhaps the audience is wrong, the offer is weak, the course page is unclear, or the price does not match the perceived value.
Suppose a course costs ₦50,000 and the creator offers a 30% commission.
Your commission per qualifying sale would be ₦15,000.
If you generate 10 qualifying sales, you earn ₦150,000 in gross commissions before any personal marketing expenses or other applicable costs.
The calculation is simple, but generating those sales requires research, credibility, relevant traffic, and effective promotion.
The advantage of this method is that you can participate in the digital education market without having to create every product yourself.
You are not paid merely because you share a link. You earn when you deliver the result defined in your agreement, usually a tracked sale.
Lead generation is one of the most practical ways to monetise digital marketing because it connects directly to what businesses need: potential customers.
A lead is a person or organisation that has shown some level of interest in a product or service and provided information that allows the business to follow up appropriately.
For example:
Businesses often have products and services ready to sell, but they need a consistent way to find suitable people who might buy them.
That is where I can come in as a digital marketer.
Instead of selling a company a vague promise of “more visibility”, I can offer a measurable service: helping it attract and identify potential customers.
Start with a sector where businesses have a clear need for customers and where you can understand the buying process.
Examples include real estate, education, professional services, software, logistics, and business consulting.
Research the sector before choosing a client. Consider the typical value of a customer, how quickly leads are converted, the client’s reputation, and whether the business can handle the enquiries you generate.
This is one of the most important steps.
A lead should not be defined vaguely. You and the client should agree on the criteria.
For example, a qualified lead for a real estate business might be someone who:
You should also establish how duplicate, invalid, unresponsive, and out-of-scope leads are handled.
Depending on the product and audience, you can use:
For example, I could work with a real estate company to create a campaign targeting people interested in buying property in Abuja.
The campaign could lead to a landing page where interested people submit their preferred location, budget range, and contact details. With appropriate consent and clear expectations, the company can follow up with suitable properties.
My job is to help create the system that brings those potential buyers into the sales process.
There are several possible arrangements.
The right arrangement depends on the sector, the complexity of the campaign, your responsibilities, and the client’s sales process.
Suppose a business agrees to pay you ₦5,000 for each valid, qualified lead.
If you generate 40 accepted leads, your gross fee would be ₦200,000.
That is an illustrative calculation, not a market-rate claim.
Before accepting a pay-per-lead arrangement, estimate the cost of advertising, your labour, the likely lead quality, and the client’s ability to convert leads into customers. Agree on attribution and payment terms in writing.
A lead-generation campaign that produces many cheap but irrelevant enquiries can be worse than a smaller campaign that attracts serious buyers.
The goal is not to collect contact details indiscriminately. It is to connect businesses with people who genuinely want to explore their products or services.
Another way I make money online is by helping businesses influence how people understand, perceive, and respond to their products or brands.
This can include brand promotion, sponsored educational content, product demonstrations, promotional campaigns, and brand partnerships.
I do not believe that every business needs to shout louder than its competitors. Sometimes, it needs someone who can explain its value clearly, demonstrate how its product works, and help potential customers understand why it may be relevant to them.
This is particularly useful when a company has a good product but struggles to communicate its benefits to the right audience.
You do not necessarily need millions of followers.
A smaller, relevant audience can be valuable if its members match the company’s target customers or trust your expertise.
For instance, a technology educator might be useful to a software company targeting small businesses. A real estate content creator might help a property developer reach prospective buyers. A marketing professional might help an e-commerce brand explain a new product.
Rather than telling a business, “I can promote your brand”, explain exactly what you can deliver.
Your offer could include:
Include your professional background, audience profile, relevant platforms, examples of your work, engagement or reach data where available, proposed deliverables, timelines, and pricing.
If you are new, you can create a sample campaign to demonstrate your approach. Do not invent audience statistics, customer results, or brand partnerships.
Identify companies whose products are relevant to your audience and send a short, tailored proposal.
Explain the problem you can help them solve, the audience you can reach, and how you will measure the campaign.
Track relevant results such as reach, clicks, enquiries, registrations, product demonstrations, and conversions.
Agree on how the business will measure success before the campaign begins.
You can negotiate a fixed campaign fee, a monthly brand partnership, a fee per deliverable, or a combination of a base fee and performance-based compensation.
The amount depends on your audience, expertise, production workload, campaign scope, and demonstrated results.
Always disclose paid endorsements and material relationships appropriately, and never make claims about a product that you cannot substantiate.
The important lesson is that you do not need to own the product to earn money from helping the right people discover it.
This is another method I consider valuable because it combines education, public speaking, marketing, and lead generation.
A webinar is an online seminar, workshop, demonstration, or presentation delivered to an audience over the internet.
Businesses use webinars to educate potential customers, explain complicated products, demonstrate solutions, answer questions, and move interested people closer to a purchase.
I can host a webinar on behalf of a company, explain its services or products, engage its target audience, and help interested participants understand the next step.
The business benefits from a structured opportunity to communicate with potential customers. I am compensated for the work and value I provide.
Look for businesses with products or services that require education before customers feel comfortable buying.
Examples include:
The webinar should not feel like an extended advertisement.
For example, instead of proposing “Come and Buy Our Software”, suggest “How Small Businesses Can Reduce Repetitive Administrative Work Through Automation”.
The company can then demonstrate how its software helps address the problem.
For a real estate company, a topic might be “What First-Time Property Buyers Should Check Before Paying for a Property”.
The company gets an opportunity to educate potential customers while introducing its relevant services transparently.
You might be paid to host and moderate the webinar, prepare the presentation, attract registrations, deliver the educational session, or help generate qualified leads.
These are different responsibilities, so define them clearly.
Possible payment structures include:
Do not assume that every company will pay for registrations or sales. Agree on the model in advance.
Depending on the agreement, you can promote it through social media, email, relevant communities, a landing page, paid advertising, and partnerships.
Use a registration form that explains the webinar, the intended audience, and what participants will learn. Collect only the information you need, with appropriate consent for follow-up.
A useful webinar structure is:
After the event, report the number of registrations, attendees, engagement, qualified enquiries, and other agreed metrics.
Imagine a company hires you to host an educational webinar for ₦100,000.
If you deliver the agreed session and meet the contract terms, your hosting fee is ₦100,000 before expenses and applicable taxes.
You might negotiate a higher fee for additional responsibilities such as creating the presentation, promoting the event, or managing the registration funnel. Alternatively, you might agree on a smaller hosting fee plus a performance-based commission.
These are illustrative figures, not guaranteed rates.
The opportunity is that you can monetise your ability to communicate, educate, and build trust without having to own the product being promoted.
If you can explain complex ideas clearly, engage an audience, and guide people towards an appropriate next step, businesses may have a reason to pay for your services.
Beyond the methods above, there is another opportunity worth considering: selling digital marketing services directly to businesses.
Not everyone wants to create a course or build an audience. Some people would rather use their skills to solve a specific business problem and charge for the work.
This is a practical starting point for beginners who want to build experience, a portfolio, and relationships with paying clients.
You do not need to master every aspect of digital marketing before offering a service. Start with one skill you can deliver competently.
Start by choosing one service and one type of customer.
For example, you could specialise in lead generation for real estate companies in Abuja or social media marketing for education businesses.
Then follow this process:
A sample audit should demonstrate your ability to think, not simply criticise the business.
For instance, you might show a training company how its course page could communicate the learning outcomes more clearly, or explain how a real estate business could improve the way it captures enquiries.
Pricing depends on your experience, the complexity of the project, the value delivered, and the local market.
You might charge per project, per campaign, or through a monthly retainer. Advertising spend should be distinguished from your management fee.
Start with a scope you can deliver well. As you build experience and evidence of results, you can refine your pricing and offer more comprehensive services.
Your first goal should not be to look like a large agency. It should be to become someone a business can trust to solve a defined problem.
The digital marketing landscape also offers opportunities beyond direct client work and course sales.
I consider these complementary methods because they can support the business models already discussed.
Affiliate marketing allows you to earn a commission by promoting another business’s products or services through an agreed tracking system.
You can build content around products relevant to a specific audience, explain their benefits and limitations, and direct interested people to the merchant.
For example, a creator who teaches website development could recommend relevant hosting services, software tools, or design resources through an authorised affiliate programme.
The key is relevance and trust. Recommending a product merely because it offers a high commission can damage your reputation if the product is unsuitable for your audience.
Content marketing involves creating useful information that attracts and educates a target audience.
SEO helps search engines understand that content and helps people discover it through relevant searches.
For example, an article titled “How to Generate Leads for a Real Estate Business in Nigeria” could attract business owners researching that exact problem.
The article could explain practical lead-generation strategies and introduce a relevant service or training programme.
You can monetise useful content through consulting, service enquiries, digital products, affiliate partnerships, or other legitimate business models.
Google’s official SEO Starter Guide recommends making content useful, readable, well organised, and easy for both people and search engines to understand.
SEO takes time, and no one can guarantee that a particular article will rank first. The objective is to build relevant visibility and a useful resource that can continue attracting potential customers.
AI tools can help digital marketers research topics, draft content, generate creative concepts, analyse data, and build certain automation workflows.
For example, you might help a training company organise course enquiries, route them to the appropriate sales representative, and send relevant follow-up messages.
You could charge for setting up the workflow, maintaining it, or providing ongoing support.
However, AI is not a replacement for understanding the customer, checking accuracy, respecting privacy, or measuring results.
The most valuable service is not simply using an AI tool. It is helping a business solve a problem more effectively with the appropriate technology.
There are many ways to make money through digital marketing, but I do not think you should attempt all of them at once.
I would evaluate each opportunity using four questions.
These questions help me distinguish between a trend that attracts attention and an opportunity that can support a business.
A skill can be popular and still be difficult to monetise if the market is crowded, customers are unwilling to pay, or the product does not solve a meaningful problem.
The goal is not to chase every trend. It is to identify a market, understand its needs, and build a dependable way to serve it.
If you are in Nigeria and want to start making money online, I recommend beginning with a manageable plan rather than waiting until you know everything.
Here is how I would approach the first 30 days.
Select one skill that interests you and has a clear commercial application.
It could be lead generation, social media management, copywriting, SEO, paid advertising, affiliate marketing, or webinar hosting.
Learn the fundamentals and practise with a realistic project.
If you choose lead generation, for instance, study how to define a qualified lead, build a simple landing page, and track enquiries. If you choose copywriting, practise writing a landing page for a specific product.
Do not spend the entire week consuming tutorials without producing anything.
Decide what you will sell and to whom.
Examples include:
Prepare a sample, portfolio page, demonstration, or short case study where possible.
If you intend to sell a course, create a small, useful product or validate demand before investing heavily in production.
If you intend to promote someone else’s course, obtain permission or join an appropriate affiliate programme.
Make a list of suitable businesses, potential partners, or customers.
Contact them with personalised messages that explain the problem you can solve and the outcome you propose to deliver.
Publish useful educational content related to your offer. Answer questions in relevant communities and invite interested people to learn more.
If you are selling a course, consider a free webinar or demonstration. If you are seeking a lead-generation client, explain how you will define, attract, and track qualified leads.
Your goal is to start conversations with the market, not simply accumulate followers.
Review the response to your offer.
How many people engaged? How many requested details? How many registered, purchased, or booked a meeting?
If you have a paying customer, deliver the agreed service and document the outcome honestly.
If no one is buying, do not immediately conclude that digital marketing does not work. Investigate whether the offer is clear, the audience is appropriate, the price is reasonable, and the problem matters enough to motivate a purchase.
The first 30 days should give you practical experience, evidence, and a clearer understanding of what to improve. Earning income during that period is possible, but it is not guaranteed.
I believe people can lose valuable time by approaching digital marketing without a clear business model.
Here are several mistakes I would avoid.
Yes. You can offer marketing services, generate leads for businesses, promote products through authorised affiliate programmes, host webinars, or work as a brand promoter. You can earn from delivering services or generating agreed results without owning the product being sold.
Yes. You can create and sell online courses through platforms such as Selar. Your success depends on choosing a relevant topic, creating useful learning materials, pricing appropriately, building trust, and reaching potential customers.
Yes, when the creator or rights holder has authorised the arrangement. Affiliate marketing generally pays you for qualifying sales tracked through your referral link. Reselling requires the appropriate rights and terms. You should not copy, redistribute, or claim ownership of another person’s course without permission.
Depending on the agreement, they can receive payment per qualified lead, per booked appointment, per completed sale, through a monthly retainer, or through a combination of fees and performance-based compensation.
No. Some digital marketing models depend on an audience, but others depend on professional skills, targeted outreach, search traffic, partnerships, or a small but relevant community. You can start by solving a specific problem for a small number of customers.
Choose a skill that matches your interests and the needs of a market you can access. Lead generation, copywriting, social media management, SEO, paid advertising, and email marketing are possible starting points. The best choice is one you can learn, practise, demonstrate, and eventually sell competently.
There is no universal timeline. Someone who already has a useful skill and access to potential clients may secure a paid project relatively quickly. Building an audience, ranking in search engines, or developing a profitable course business may take considerably longer.
Yes. AI can support content creation, research, reporting, and marketing automation. You can offer these capabilities as part of a service, but you still need to understand the client’s problem, check the quality of your work, and deliver a useful outcome.
My approach to making money online is built around a simple idea: find a need, identify how you can meet it, and create a business model around the value you provide.
When I know a subject well, I can package my knowledge into a course and sell it.
When I identify a high-demand skill that someone else teaches better than I do, I can explore an authorised affiliate or reseller arrangement.
When businesses need potential customers, I can help generate qualified leads.
When companies need to communicate their value, I can help promote their products and brands.
When businesses need to educate an audience and guide interested people towards a decision, I can host webinars and negotiate compensation for my work.
These methods are different, but they share a common foundation: understanding people, communicating value, and connecting a genuine need to a relevant solution.
You do not need to start with all five methods. Pick one that matches your current skills and resources.
If you have knowledge worth teaching, develop a small course. If you can communicate clearly, explore webinar hosting. If you understand how to attract potential customers, investigate lead generation. If you have an audience or can reach a relevant community, consider brand partnerships or affiliate marketing.
Then take one practical step today.
Research a market. Speak to a potential customer. Build a sample. Contact a business. Validate a course idea. Create your first offer.
Do not wait until you feel like an expert at everything. Learn, practise, be honest about your capabilities, and improve through experience.
Digital marketing is not a magic button for instant wealth. It is a collection of skills and business models that can help you earn money when you apply them to real problems and execute consistently.
The opportunity is not merely to learn digital marketing. It is to learn how to turn digital marketing into a source of value, income, and long-term business growth.
