The 6 Best Keyword Research Tools For Affiliates: A Clickbank SEO Guide

By Hanson Cheng

If you’re an affiliate marketer with a niche website or blog, affiliate marketing keyword research is the foundation of your SEO efforts. Without proper keyword research, you won’t be able to rank your site high in the search engines and get the traffic you need to make sales.

While many SEO “gurus” try to make this topic sound complicated, it actually isn’t. In fact, with the right tools, keyword research can be pretty easy and fun. As you start going down the rabbit hole and uncovering all the different keywords you can target, it becomes addicting!

With that said, there are many different keyword research tools, and not all are created equal. In this post, I will be discussing the best keyword research tools for affiliates on ClickBank who do SEO with a niche website or authority site. By the end, you should have a pretty good idea of which tools you need to take your keyword research to the next level.

Let’s get right into it!

What is Keyword Research, And Why Is It Important?

When people go to a search engine and type in a word or phrase, they use specific words to do their search. This is called a “keyword phrase” or “search query.”

For your website to appear in the search results, you need to target keywords relevant to what people are searching for. Ideally, you can them to rank product review content talking to organic visitors with a “commercial intent” – in other words, people who are ready to buy!

But all of this is only possible with strong keyword research to find the right keywords to target for your website or blog.

The last thing you want to do as an affiliate is to spend all your time and effort building an affiliate website around keywords that nobody is searching for. Not only will this make it hard to get traffic, but you’ll also have a tough time making sales (and commissions) from your affiliate site!

Doing the proper research upfront can save you a lot of time and effort in the long run.

6 Key Features of An Affiliate Marketing Tool

As you can see, the features of an affiliate marketing tool are pretty varied. Some features are essential for almost any SEO project, while other features are specific to affiliate marketing and affiliate websites.

So, if you want your affiliate marketing effort to yield the best results, then there are 6 essential elements that your chosen SEO tool should have!

1. Keyword Research Abilities

The first and most important feature of any good SEO tool is the ability to do keyword research. After all, that’s the bread and butter of SEO!

Your SEO tool will provide various methods for finding keywords, including general and niche-specific keyword databases and suggestion tools that give you ideas for new keywords based on what you already rank for.

Getting accurate keyword complexity scores and search volume metrics is also important. Otherwise, you won’t know how difficult it will be to rank for a given keyword or how much traffic you can expect if you manage to rank for it.

2. Backlink Data

Another essential SEO metric is backlinks. To rank well in search engines, your website needs to have links from high-quality websites pointing to it.

The best keyword research tools will have a database of backlinks that you can use to see which websites are linking to your competitors and what kind of link text they’re using (anchor text). This information can be used to successfully build affiliate marketing backlinks to boost your domain authority and make ranking in the search engine results pages (SERPs) easier.

3. Traffic Analysis

Knowing how much traffic a website gets is another essential SEO metric. The best keyword research tools will have detailed traffic analysis features that allow you to see how many people are hitting the website and where that traffic is coming from (organic search, direct, referrals, etc.)

This information can be used to improve your own website’s traffic by targeting the same sources of traffic that your competitors are getting theirs from.

4. SERP Analysis

SEO is about ranking well in the SERPs. The best keyword research tools will have SERP analysis features that allow you to see how your website is currently performing in the SERPs for various keywords and how your competitors are doing.

This information can help you adjust your SEO strategy to improve your current SERP rankings.

5. Competitor Analysis

To beat your competitors, you need to know what they’re doing. The right keyword research tool will be the one with detailed competitor analysis features that allow you to see what keywords your competitors are targeting and what their backlink profiles look like.

Increasing affiliate marketing sales comes down to being able to outrank your competitors in the SERPs. The right information can improve your SEO efforts by targeting similar keywords as your competitors and building similar (or better) backlinks.

6. Long-Tail Keywords

Long-tail keywords refer to keywords that are very specific (generally made up of multiple words) and usually have lower search volume than their shorter-term counterparts. The best keyword research tools will have an updated database of long-tail keywords you can use to find ideas for new keywords to target.

Long-tail keywords are often easier to rank for than broader and shorter ones, so they can be a great way to drive high-quality traffic to your website with less competition.

As part of your SEO keyword mapping strategy, the content you create based on long-tail keywords can link to other, high-traffic pages on your website, resulting in more overall traffic and improved rankings across the board.

What Type of Marketer Can Benefit From Doing Keyword Research?

Various types of marketers can benefit from doing keyword research. Here are a few examples.

An Affiliate Starting An Ecommerce Store

If you’re an affiliate who’s just starting out in ecommerce, keyword research can be a great way to find product-related ideas. You can use keyword research tools to find search terms to create content around, along with products to add to your site.

This means that you’ll have a good chance of ranking well in the SERPs for these keywords, which can result in more traffic and sales.

For example, suppose you’re going through the process of learning how to start to reverse dropshipping. As opposed to just starting to add products to your site new and hoping for the best, the proper keyword research will allow you to find high-quality products with the right search volume and competition you can handle.

Businesses Interested In Expanding Key Business Areas

Businesses interested in expanding into new areas can use keyword research to find popular keywords related to these areas.

Using the right keyword tools, you can get an idea of the level of interest your target audience has in a set topic, helping you decide whether or not it’s worth expanding into them.

For example, a business that promotes ID scanning software and is looking to expand into KYC compliance might use keyword research to find popular keywords related to this new topic. If they see a high level of interest in this topic and their current tool can be modified to help with such compliance, they might decide to expand into this area.

Businesses That Want to Offer an Affiliate Backend

Getting affiliates to promote your products is a great way to drive sales and grow your business. But in order to get affiliates on board, you need to offer them a backend that’s easy to use and provides all the information they need!

Consider a people search company that wants to offer an affiliate backend. In order to get affiliates on board, they need to offer a backend that provides affiliates with the right information, such as search volume and competition data for various keywords.

The right keyword research tools can help them find the right keywords to target and provide other information that can be used to improve the backend. This can result in more affiliates signing up to promote their products, which can drive more sales.

Affiliates That Want To Scale Their Business

What does it mean to scale a business?

This question can have multiple answers, but generally, it means sustainably growing your business beyond its current size.

One way to achieve this is by increasing your traffic and conversions. If an affiliate business depends on search engine optimization to get traffic, then keyword research can be a great way to achieve this.

By finding popular keywords with high search volume and low competition, this affiliate can optimize their website and content for these keywords, resulting in more traffic and conversions. And, as we all know, more traffic and conversions equals more significant business!

Best Keyword Research Tools for Affiliates Wrap-up

Keyword research is essential to search engine optimization and should be conducted regularly to ensure that your website ranks well for the right keywords – and as a way to uncover trending keywords to inform your overall strateegy.

Many different keyword research tools are available out there, each with its own set of features that cater best for unique business use cases.

But in the end, no matter what your needs are, there’s a keyword research tool or two out there that can help you. Get started today and see how you can benefit from doing keyword research!
