When you’re not sure whether to buy a Nespresso, Breville, or a DeLonghi espresso machine, you likely turn to Google. And what does Google give you? An entire list of articles named “x best espresso machines”.

You’ve just discovered one of the most popular affiliate marketing strategies. Comparison and review sites take the hard work of examining and evaluating consumer goods away from us and, at the same time, promote them on behalf of the seller. 

It’s a great way to generate income without selling anything. And for the espresso machine seller, it’s a fantastic way to advertise. But that’s just one of the many ways to leverage affiliate marketing. 

In this article, we’ll walk you through our step-by-step guide to what affiliate marketing is and how it works.

What is affiliate marketing?

Digital affiliate marketing is a form of advertising where a product owner or vendor lets external websites (affiliates) promote their product and compensates them for traffic or sales they generate. It’s a bit like Batman and Robin, vendors team up with publishers for mutual gain, making it a win-win for everyone involved. 

How do the parties benefit? 

  1. Vendors keep their marketing costs low through performance-based payouts.
  2. Affiliates, or publishers, earn from promoting products, without any product-related costs.
  3. Consumers get a better chance of finding what they want.

Dividing the workload allows both the vendor and the affiliate to focus on their strengths and what brings in the money. The product owner concentrates on developing the best product or service offering, while the affiliate zeroes in on publishing and promoting it. 

Affiliates can be any type of website using any variety of tools to distribute content. They could be a news media channel, a blogger, an email, or a PPC marketer. For consumer products, review and comparison sites are trendy affiliate activities. Social media and influencer marketing offer additional opportunities for affiliate marketers.

The point is to reach an audience that’s relevant to the vendor. That’s another reason businesses open an affiliate program: to leverage the publishers’ audience and expand their reach. 

Affiliate marketers’ success often depends on the audience reach. So, if you were wondering how to start affiliate marketing, this is your first action item. You need to prove to the product seller that you can indeed provide lots of valuable traffic. 

Vendors use affiliate research tools to find new and high-quality traffic sources, identify the best affiliate partners, and optimize their results. In this article, we are taking a deep dive into how affiliate marketing works, how to do affiliate marketing as an advertiser and publisher, and how to analyze and strategize for high ROI and revenue.

How affiliate marketing works

How affiliate marketing works

Affiliate marketing involves three main stakeholders: the seller or vendor, the affiliate or publisher, and the consumer. Sometimes there’s also a fourth player, the network, involved. Each has a unique and critical role:

Who’s involved in affiliate marketing?

The seller or vendor

The seller or vendor might also be referred to as the brand, the merchant, or the retailer. If that’s you, you’re the one with the product idea or an existing product or service for sale. You might run a one-person business, a store, a manufacturer, or even a large international enterprise. There is no limit to the company size or the variety of physical and digital products a vendor can market through affiliates.

The affiliate

The affiliate is often also called the publisher because their job is, well, to publish. As an affiliate, you’ll use your own resources and advertising space to promote the seller’s goods and collect a commission, based on a predetermined goal. That rate might be attached to sales, conversions, leads generated, or a simple click-through rate (CTR).

Affiliates can be individuals or larger corporations, or even brands that partner with another brand to gain exposure. For example, a gardening company might also act as an affiliate partner for a company that manufactures gardening tools, advertising them alongside its gardening services.

The consumer

The third stakeholder is the ultimate source of revenue: the consumer who buys the product or service. They might not even be aware of their part in the affiliate relationship, especially when they’ve found the product through promotions that appear organic rather than sponsored.

The network

In some online affiliate marketing strategies, a network sits as an intermediary between the vendor and affiliate. Often the network will handle shipping and billing, as well as provide a database, software, tracking, and full reporting of all affiliate marketing activities.

3 types of affiliate marketing strategies

1. Unattached affiliate marketing

In unattached affiliate marketing, the affiliate publishes advertisements that promote the seller’s merchandise. There’s no direct connection between the affiliate site’s content and the advertised product; the publisher simply places advertising material on their site. The vendor provides the ad creatives, such as PPC ads, banners, and other display ads, but there is no deeper partnership between the two.

Unattached affiliate marketing is the most common type, and it generates affiliate income and drives traffic for the seller. For example, when you go to an online dictionary, you may find an advertisement for a local furniture shop next to an online dating site ad. In this case, the dictionary functions as an affiliate for both the shop and dating sites since they are both using the dictionary to promote their online business.

2. Involved affiliate marketing

On the opposite end of the spectrum, there is involved affiliate marketing. The affiliate takes an active role in promoting a product or service they understand or have tried it themselves. They introduce, explain, review, or even recommend it within their own content.

This requires a connection between the affiliate and vendor, and often product or service trials. Typically affiliates focus on a specific niche and they use blogging or social media to create unique content. These affiliate marketers leverage their  authority and inside knowledge to grow numbers of subscribers or followers. 

If this sounds like influencer marketing to you, you have a point. This powerful affiliate model gave rise to the first influencers when affiliates built authority and a connection with followers, often engaging with their audience. As you might imagine, ecommerce technology and digital products frequently work within this model.

3. Related affiliate marketing

Finally, we have something in the middle. In this type of affiliate marketing, the affiliate will promote the company’s products that are related to their site, but without directly mentioning them in their own content. For example, a hotel may advertise local holiday attractions on its website since there’s a clear overlap with its own service, without directly promoting the attractions in any of its content.

How to create your own affiliate program

You don’t have to be Amazon or a large brand to run an affiliate program. Today, more than 80% of all brands have affiliate programs, and. affiliate marketing is responsible for 16% of global ecommerce sales.

1. Assess your potential affiliate types

Digital affiliate marketing has been around since William J. Tobin’s first patent application in the mid-1990s, and it continues to offer a wealth of possibilities for pumping up your lead generation.

First, define who your target demographic is. With audience analysis, you can identify your most likely prospects and discover what type of content this audience prefers. Then, you can craft your affiliate marketing campaigns with that precise audience in mind, making sure you speak their language and appear on their most popular channels.

Affiliate Marketing

Next, think about the different impacts each type of affiliate has, whether that’s an increase in traffic, conversion rate, sales, or a boost to your brand credibility. Let’s see what popular affiliate site types can accomplish. 

  • Coupon sites easily promote special deals by letting your partners give exclusive affiliate offers and discounts
  • News & media sites reach a huge general audience
  • Content sites increase your credibility on content marketing sites that can improve your search engine ranking
  • Review sites show what sets you apart from the competition with detailed product reviews that can support your eCommerce strategy
  • Loyalty sites boost your customer retention (especially popular in eCommerce programs)
  • Value-driven blogging can add a personal touch and increase your credibility whether it’s on the affiliate website or as a guest post on your own blog
  • Shopping comparison demonstrate your price advantage to prospective customers
  • Email marketing engage harder-to-reach audiences with a segmented email list
  • Search affiliates increase your traffic through the affiliate’s paid search 

2. Research and create your plan

Once you’ve got an idea of where you want to sit in the affiliate landscape, you can start to research where to find the highest-quality traffic from your target audience, and build a program structure with goals to match.

Eye the competition with competitive research

Learning from your competition is always a good start. Once you understand what works for them, you can build your own plan. Find out what’s common in your industry and how your competition works with affiliates:

  • What type of online affiliate marketing do they use to promote their product or service?
  • How successful are their methods?
  • Which affiliates provide them with the best ROI?

If your competition works with large affiliates, such as coupon or media sites, find out which, and check how successful these partnerships are. Similarweb’s tool can help you find your competitors’ affiliates and compare affiliates’ performance. Discover how much traffic they generate, which keywords work best for them, which of your competitors they work with, and what’s your potential traffic share growth.

Pick a payment model

The revenue-sharing relationship between sellers and affiliates varies from program to program, but there are three main commission models, either on a flat rate or percentage basis:

  • Pay-per-sale
  • Pay based on CTR
  • Pay-per-lead

Think of your payment model like a motivational tool, encouraging your affiliate partners to operate in a way that’s best for you. Do you primarily want them to help you generate traffic, leads, or sales? At which stage in the sales cycle can affiliates offer you the most value? Answer those questions, and the choice of payment model becomes easy (well, relatively).

It’s also important to keep a close eye on the details of the terms. For example, if you pay per sale, you need to determine which click counts. If, for example, a buyer clicked on several different affiliate links before making a purchase, who is entitled to the commission? Some programs choose to attribute the sale to the first click, some to the last, and others spread the commission over the buyer journey.

Pro Tip: Consider some protective measures. Let’s say you pay per click, and your affiliate generates tons of traffic. How do you ensure the traffic is valuable? Set criteria to ascertain affiliates are credible and know what they are doing.

Consider your referral cookie lifetime

Successful affiliate marketing strategies take advantage of affiliate links and web cookies, small pieces of data stored on a user’s computer when they click on the link. The cookie duration (or, lifetime) is typically set by default to 30 days but can stretch up to 90 days (or more) depending on the industry. That gives your affiliate a window within which to make their commission on any conversions, so, naturally, most affiliate partners are drawn to programs with a longer cookie lifetime.

Decide your commission type

  • Site-wide commission – The affiliate gets paid for any purchase on your site made by the referred customer
  • One-time commission – The affiliate gets paid once when the customer completes a specified action, such as a purchase within a specific product range
  • Recurring commission – The affiliate gets paid for as long as the customer remains signed up, used primarily on subscription programs

Look for affiliates with killer content  

All digital marketing efforts are interconnected, so you want affiliates with high-quality content and winning search engine optimization (SEO) that ranks highly on Google search. When they win, you win, so it’s worth investing in affiliates who outrank others. Take advantage of their content expertise, and you’ll see quicker results and greater visibility for your brand without having to take on a big risk.

Find your ideal affiliate partners

Before reaching out to new affiliate partners, you need to find a platform that allows you to easily pass on their affiliate commission, such as getpd.com. Alternatively consider one of the wide range of other payment methods, such as PayPal.com.

3. Recruit the affiliates you want

Now that you’ve established what you expect of your affiliate partnerships, it’s time to find your ideal affiliates. The best place to start is your existing network of customers, contacts, and business partners. After all, who’s better suited to promote your affiliate products than happy customers?

Approach them via:

  1. Email
    By creating a dedicated email campaign to promote your affiliate program, you can reach out to the influential affiliates uncovered by your competitor analysis. Consider adding a banner to your email signature, or even better send personalized emails and make an offer.
  2. Social
    You’ve already built up your following on social media, so it’s a great way to promote your affiliate program too. Connect with potential affiliates but also expand your network to find the contacts you need.
  3. Your website
    If you’re serious about growing your partner network to support online marketing, it deserves a dedicated webpage on your website, optimized for SEO. Provide all the relevant information potential affiliates will be looking for, and draw out the key benefits your program offers, such as commission rate, cookie lifetime, and any existing success stories. Make your sign-up form easy to find and simple to complete, removing friction barriers that might otherwise get in the way.
  4. Advertising
    Treat your affiliate program the same as any product, and use advertising to expand your reach. When you first launch the program, you need to promote it with the same intensity as a new service or product. So you might want to allocate a portion of your budget for PPC ads or Facebook ads to target your specific niche. Paid social media ads can be effective here, as well as finding industry or affiliate forums with partners who can refer you onwards to potential affiliates. Consider approaching big affiliate companies and publishers, or using recruiting tools provided by the more popular affiliate networks.

Pro Tip: To attract affiliates who are most suitable for your business, try to think about what they might be looking for, such as referral cookie lifetime, your payment system, and favorable commission rates or bonus options.

How to become an affiliate marketer

1. Choose or identify your niche

Affiliate marketing for beginners is best with an unattached affiliate setup. You can place advertising on your blog, website, or profile. If you already have a large audience for your blog or YouTube channel, you may consider promoting unique content and entering an involved partnership.

Identify the audience your website and content attract, so you can match that demographic up with a suitable affiliate program. You might already have a clear sense of your niche or specialism, or you might be looking to branch out and access a new audience.

Either way, the more clearly you can define your demographic with audience analysis, the more valuable you are to affiliate programs, and the easier it is to select the perfect platform.

2. Pick a platform

Next, match your audience and niche to an industry, product type, or service area. Check the relevant brands and what kind of affiliate programs they offer. Examine the commission rates, the cookie lifetime, and any other benefits each platform might deliver, such as marketing materials and support.

Also, investigate who the affiliate partners are. You want to know who you compete against for the audience’s attention. Similarweb can provide you with data on the referring sites and help you evaluate the level of audience engagement.

3. Drive traffic with great content, and use the right affiliate links

You don’t have to limit yourself to one vendor, but don’t start with too many either. Select the affiliate programs you want to sign up for and start creating content. If you place ads or promote the vendor’s content, update your affiliate links for each offer and share those links within your content or on your social media. 

Keep producing the valuable content your audience is familiar with and you’ll be ready to collect a commission every time someone uses your links to make a purchase.
