I recommend using the free tools in Ryan Robinson’s blog for beginners; and more importantly, I highly advise reading the thorough and easy-to-understand tutorial articles about keywords and how to use keyword tools to understand the dynamics of keyword optimization in content writing and site structure. I have included more specialized and useful keyword generators such as “Answer The Public,” “KeySearch LSI Keyword Generator,” “Google Trends,” and social media AI keyword generators.

Checklists of Free Keyword Research Tools

Twin Word Ideas

This is an AI keyword generator.  The homepage targets the expertise this too has to offer to affiliate marketing.

Twin Word Ideas targets the relevant keywords for a niche, and it supports 46 languages and more than 230 geographic target locations.

It uses an AI to compile a list of popular topics and user intent (user queries); which provides you with a listing of suggested topics to use in content writing.

A FREE plan is available, but it has a daily free research limit.  You can always resume your keyword research the next day.

Google Keyword Planner

This tool is awesome, but it requires a tutorial.  Google Keyword Planner is another useful and powerful keyword research tool, and it's completely FREE.

It is used for Google Ads, so it specializes in PPC (pay per click) keyword search.

It is completely free to use if you don't buy Google Ads which means that there is no daily limit for need for an upgrade.

The tool has two main features.  The first is for exploratory keyword search and discovery; and the second is for researching 'search volume' (or customer queries) and forecasting.

When you enter the seed keyword, it compiles a list of monthly search volumes, change over time, competition, ad impression share, and bid ranges.

Refine your keyword search by brand or non-brand keywords; for example, search luxury fine lingerie rather than simply 'lingerie' for a more in-depth research volume.

As a PPC tool for Google Ads, it has the added feature of forecasting an organic search engine traffic strategy by forecasting where your keyword or long-tailed keyword ranks in the worldwide web.

Google Keyword Planner and Google Analytics are two useful and highly recommended tool to learn how to operate and SEO your website in keyword search.  Use the tutorials in Google and YouTube to build your skill set.

You only need a Gmail account to login and use Google Keyword Planner and Google Analytics.

ahrefs Free Keyword Generator & Free Keyword Difficulty Checker

Use their database to find relevant keywords from over 8 million queries.  "Just enter up to 10 words or phrases and choose from 1 to 6 keyword ideas."  You can search by 'engine' (Google, Bing, YouTube, Amazon); and by 'country' (worldwide listing).

The ahref Free Keyword Difficulty Checker is also a valuable resource to research keyword search volume.  The homepage explains the importance of researching keyword difficulty in affiliate marketing.

ahrefs Keyword Difficulty Checker
Keyword Difficulty measures how hard it is to rank in search engines for a specific 'key' word or phrase. 

A high keyword difficulty means that these key words or phrases have a  high competition which means that it would require months and even years to build a high Google authority for your website by using content writing and linking to trustworthy websites that have a high Google authority in order to start receiving organic search engine traffic by using these highly competitive key words and phrases.

It is highly suggested by professional bloggers such as Ryan Robinson, to use keywords and phrases that have a medium to high keyword research volume and a low keyword competition.

If you are new to keyword research, then I highly recommend reading the articles explaining the keyword process and the SEO process in blog articles written by Ryan Robinson.  These articles will help you learn and build the skills you need for promoting in affiliate marketing and to optimize your website with the right keywords to quickly gain organic search engine traffic.

Read Ryan Robinson's articles and take notes to understand what keywords are, how to find the right keywords to optimize your website for organic search engine traffic, to boost traffic to your content writing,  to use keywords in on-page SEO, and how to optimize your overall website in the back office of the SEO Suite.
