Choosing the right keywords for your website’s content strategy can help your search engine optimization efforts as well as attracting the right type of visitors.

To help you do this, you need a keyword research tool that will give you access to accurate data and reveal long tail keywords that will help you to rank.

In this blog post, I’m going to give you 12 of the best keyword research tools available that will help you to choose the right keywords for your website.

1. SEMRush

Website: semrush.com

Price: From $119.95/m. Free trial available.

Best feature: Keyword Magic

Semrush keyword research tools

SEMRush is not only a keyword research tool but a suite of tools for online marketers. You can do keyword research, SEO research, content marketing research and more with this robust set of tools.

The keyword research tools available in SEMRush has made the tool one of the leaders in the industry for many years. You’ll find this suite at the top of most keyword tool lists because it is just that good.

Some of the best features of SEMRush are:

  1. Keyword Magic Tool
  2. Keyword Gap Tool
  3. Topic Research Tool

Keyword Magic allows you to input a single seed keyword and generate lots of other related keywords in your niche, including long-tail keywords. You can then explore different sub-categories to find even more keywords and topics you may not have thought about.

The Keyword Gap tool allows you to check competitor sites for unique and common keywords they rank for. SEMRush checks for organic and paid keywords.

After finding keywords, you can save them in the keyword manager for later use.

One of my favorite features is the topic research tool found in the content marketing section of the tool. You enter a topic and it generates a mindmap of related ideas, interesting topic headlines, questions your audience asks about the topic and related keywords.

SEMRush is a very useful keyword research suite but it is very pricey. You can use it for free with limitations that include limited results and a cap on the amount of daily requests you can make. Currently you can only make 10 requests per day.

The paid subscriptions are best for people who need to do a lot of research. There are three paid plans starting with the Pro plan which costs $119.95/month. The Guru plan costs $229.95/month. You can try both plans with a 7 day free trial.

There is also a Business plan which costs $449.95/month which is great for large businesses and agencies. There is no free trial for this plan.

2. Ahrefs Keyword Explorer

Website: ahrefs.com

Price: From $99/m.

Best feature: Keyword difficulty

Ahrefs keyword generator

Probably better known for its backlink checker tool, Ahrefs also has a very good keyword tool which rivals that of SEMRush.

Ahrefs keyword tool probably has the largest database, with 8 billion queries, as it pulls data from multiple search engines across 171 countries around the world. With such a huge database, this means that the tool can help you find opportunities other tools may not find.

Ahrefs data is updated every month to ensure you get the most accurate data each time. Google isn’t the only search engine supported. The tool also can estimate volumes for Bing, YouTube, Amazon, Baidu, Yandex and more which makes it even more useful.

The best feature of Ahrefs is probably Keyword Difficulty (KD). Most keyword tools will give you a keyword difficulty rating as a general estimate such as “difficult” or a percentage eg. 80 out of 100. Keyword Difficulty tells you how easy or difficult it is to rank for the given keyword and how many estimated backlinks you’ll need to get on the first page of the SERPS.

Ahrefs previously offered a 7 day free trial to use their keyword explorer. However, you’ll have to subscribe to use this tool. A Lite plan starts at $99/month for access most of the suite. The Standard plan for $199/month gives you even more features.

3. Google Keyword Planner

Website: ads.google.com

Price: Free

Best feature: Refine keywords

Google Keyword Planner

Keyword Planner is a free to use tool that comes directly from Google. It doesn’t have all the bells and whistles that most of the other keyword tools have but you’re getting data right from the source.

This tool was made for uses of Google Adwords so they could get keywords for paid advertising but you can use it to get keyword search data. You’ll need a free Adwords account even if you don’t plan on running any ads.

To do keyword research in the Google Keyword Planner, you can just enter your desired seed term and get more keyword ideas, search volume and more. Or you can enter a website domain or page from any website to get an idea of what keywords they’re using.

It may not be the best keyword tool to use for SEO however you cannot deny the accuracy of the data if you’re optimizing your website for Google.

4. Keyword Tool

Website: keywordtool.io

Price: Free / From $89/m

Best feature: Keywords for multiple platforms

keywordtool io

KeywordTool.io database works by giving you lists of keywords based on autocomplete suggestions from 11 different search engines.

  • Twitter
  • Pinterest
  • Apple App Store
  • Google Trends

The free version of Keyword Tool gives you lots of suggestions based on your query and you can generate a lot of keyword ideas from these.

9. Answer The Public

Best feature: Alphabeticals

Answer The Public keyword tool

Answer The Public is one of my favorite keyword research tools. I started using this as an alternative to Google autocomplete.

With Answer The Public, you don’t get search volume and difficulty scores and analysis. The tool simply gives you a list of keywords based on what you would find using Google’s autocomplete while searching a keyword. Other tools do this but not as well as Answer The Public.

Results are sorted and displayed visually in separate groups representing:

  • questions – queries starting with what, who, why etc.
  • prepositions – queries containing for, is, to, with etc
  • comparisons – queries with vs, and, or, like etc
  • alphabeticals – eg. search query + words with a, search query + words with b etc
  • related – queries related to your original seed query

You can choose to download and save the results displayed as an image or the entire results as a spreadsheet.

Answer The Public has a pro upgrade starting at $99/month which gives you access to some pro only features like hiding unwanted results, data comparison and more plus a content strategy.
