What Are Keywords?

Keywords are the phrases people type into their favourite search engine (typically Google) when they are looking for information online.

As an affiliate marketer, your job is to get “in front” of these people with your content and get them to your website where you will eventually sell them on a product which you will be paid a commission on.

Why Are Keywords Important For Affiliate Marketers?

The cornerstone of every successful affiliate marketing website is the type of traffic you get.

For affiliate marketing purposes, the best traffic you can get is from SEO (search engine optimisation) and that’s because all search engine traffic has “intent”.

Nobody goes searching on Google to waste time. They typically want to find something and many, are looking for information (and products) that could solve a specific problem they have.

There are what we call keywords with a buying intent and they’re the type of keywords you want to find as an affiliate marketer.

How To Know If A Keyword Has “Buyer’s Intent”

While I’m going to share with you a few keyword tools down below, the best tool you can use with SEO is “common sense”.

Here’s an example of what I mean:

People who search for “cat videos” are probably not looking to buy cat food. However;

Someone who’s searching for “best food for Siamese cats” is probably someone on a mission to find (and buy) the best food for their cat.

That is what I mean by keywords with “buyer’s intent”.

I can’t give you specific examples because I don’t know your niche, but to help you get some ideas going, these are typically the type of phrases people use when they are in “buying mood”.

  • How to buy _____
  • Where to buy _____
  • Product X review
  • Product X vs Product Y
  • How much does Product X cost?
  • Best ____ for _____

Makes sense?

I have a few additional resources down below to further drive the point home, but let me now tell you about some of the best keyword tools you can use to find these type of keywords.

5 Keyword Research Tools For Affiliate Marketers

Next up I have 5 keyword tools which you may want to check out (4 free, one paid) but before we get into that, one thing you should know is that there are plenty of keyword research tools out there and each one of them will present different data from the rest (so take everything with a grain of salt).

However, the below 5 are what I currently use (with the exception of one) and I can assure you that the keywords these tools will reveal will be more than enough to get you ranked for buyer-rich keywords and earning affiliate commissions.

Google’s Autosuggest Feature

One quick way any brand new affiliate marketer can find some great keywords is to see what Google is auto-suggesting to people.

These are “long-tail keywords” which typically have very low competition, and if you look hard enough, you’d be able to come up with plenty of “buyer keywords”.

How To Use Google Auto Suggest

The Google autosuggest is simple in theory but effective in practice & it works like so:

#1 – Go to Google

#2 – Start typing in your keyword and then

#3 – See what Google auto-suggests while you are typing


is answerthepublic a good keyword research tool

This is one of my favourite SEO tools that very few people know about.

What it does is that it curates all the “long tail” keywords people look for in Google.

How To Use AnswerThePublic:

#1 – Simply visit the ATP website here.

#2 – Type in a short (root) keyword.

#3 – In a few seconds, ATP will reveal to you the most commonly searched long-tailed keywords for that niche/keyword.

Google’s “People Also Ask” Keyword Tool

One other tool which I am also enjoying and having good results with is the People Also Ask feature in Google.

Now you can use the keywords you find here as a standalone article, or you can use them as sub-headings (if it makes sense to do so) in an article with your target keyword,

For example, if your “main keyword” is:

“How To Do Indoor Gardening”

You can also include the below suggestion as sub-titles (H2s) when you are creating your article.

PRO-TIP: The more you click on these keywords, the more related keywords will come up.

Neil Patel’s UberSuggest Keyword Tool

This is also another popular tool that you can use. I don’t use it often as I prefer the AnswerThePublic tool myself, but since everyone talks about it, and it’s free, I saw it fit to give it a mention here.

Here’s how you use it;

#1 – Go to

#2 – Type in your main keyword.

The tool will reveal a list of long-tail keywords which you can either target with a stand-alone article or include these keywords as sub-headings inside your main article.
