In this article, CI will introduce you to the latest free and paid keyword research tools in 2023.

Semrush SEO Tool

  • Semrush is not just a regular keyword research tool; it allows you to conduct keyword research in various ways, such as:
  • Searching for keywords using seed keywords
  • Finding keywords that bring traffic to your competitors
  • Analyzing keyword gaps

One simple way is to search for keywords based on a URL. You just need to input a URL (yours or your competitor's), and it will display all the ranking keywords for that page or the entire website.

Besides keyword data, you will see monthly search volume, keyword difficulty, and CPC for PPC.

Keywords suggesttion

Keyword suggestions are another useful feature of Semrush, showing keyword variations and related keywords. This helps you discover more search terms to target.

This makes it easy to find short-tail and long-tail keywords that you can target and outperform your competitors. The keyword difficulty score feature helps you identify easier opportunities. You can get detailed keyword data like:

  • Keyword search volume
  • Keyword difficulty score
  • Search engine results page (SERP)
  • Reports Adsense CPC

There's much more detail you need for accurate keyword research. You also have the option to sort the keyword list by keyword difficulty score, which helps you find low-competition keywords. With just a click, you can add them to your keyword management.

If you're looking for an alternative to Semrush and Ahrefs for keyword research, give SE Ranking a try.

SE Ranking provides all the features you expect from a modern keyword research tool, and it also offers additional features that you won't find in popular tools like Semrush or Ahrefs. With the SR Ranking tool, you can:

  • Research individual keywords

Ahrefs Keyword Explorer Tool

Ahrefs is one of the most popular keyword tools today. This tool provides comprehensive details, including keyword difficulty. Ahrefs uses clickstream data to show the estimated clicks you'll receive from search engines. You can use the Keyword Generator tool to generate ideas for Google, Bing, Amazon, YouTube, and other search engines.


This is useful after integrating the knowledge graph because many keywords can have significant traffic but not receive any clicks from search engines. This is due to them getting direct answers from Google's search results. An example of such a query is: "birthdate of any famous person."

Another standout feature of Ahrefs' keyword research tool is its excellent user interface and the amount of data it provides. Ahrefs offers various other features like backlink analysis and website SEO checks, to name a few. You can read a detailed Ahrefs review here. You can also create keyword lists to directly target from the Ahrefs dashboard, saving you a lot of time without using Excel.

Google Keywords Planner

Google Keyword Planner is one of the most widely used and popular keyword research tools because it's free and directly integrated with Google AdWords.

To start using this tool, you need an AdWords account (you can create a free account). Thanks to Google's data, this tool can provide you with fairly detailed keyword information. However, it also has some limitations in certain aspects. For instance, if you want to see what's happening on your website (traffic, top keywords, etc.) or the activity of a specific keyword on other search engines, you won't find that information here. Google Keywords Planner is free and serves as a basic tool for the initial stages of website SEO. But for more detailed analysis, opt for the tools listed above for better results.
