52 4 Best Free Keyword Research Tools in 2024

Keywords act as a bridge connecting users to your content, so it’s essential to choose them wisely. Although several premium tools dominate the market, there are fantastic free alternatives that offer comprehensive insights without breaking the bank.

In this article, we present the top four free keyword research tools for 2024 that can elevate your SEO marketing.

Free keyword research tools can be very useful for your SEO strategy. Here are four tools to consider:

1. Moz Keyword Explorer

Moz Keyword Explorer makes keyword research easy with its user-friendly interface and standout ‘Priority’ score feature for identifying valuable keywords. Although Moz’s free tools may provide less data compared to other platforms, this approach benefits novice marketers by providing essential metrics without overwhelming them.

The tool enables users to enter keywords to access monthly volume, difficulty, and organic clickthrough rate (CTR). It also suggests related keywords and analyses current rankings. The ‘Priority’ score provides a quick evaluation of a keyword’s value based on various metrics, including a personalized ‘My Score.’

Furthermore, Moz’s Competitive Research tool, which includes the Keyword Gap feature, helps identify keywords that competitors rank for but you do not.

2. Google Keyword Planner

Google Keyword Planner is a powerful tool for researching PPC keywords. It is free to use and does not require Google Ads, so there are no limitations or costly upgrades to worry about.

The tool allows for exploratory keyword research and provides in-depth analysis of search volume and forecasting. The ‘Keyword ideas’ function is similar to other tools. It generates suggestions based on a seed term and provides important details such as monthly search volume, competition, ad impression share, and bid ranges.

You can refine the results by brand or non-brand keywords and source websites. The ‘Forecast’ feature is particularly useful for Google Ads users as it helps in planning paid ad campaigns and budgeting. 

Google Keyword Planner can provide insights for both PPC and organic strategies. It can identify areas where organic ranking could offset PPC costs.

3. Ahrefs

Ahrefs provides a range of free SEO tools that are easy to use and cater to various needs, especially for fundamental keyword research. The suite includes tools such as the Free Keyword Generator, Keyword Difficulty Checker, and Keyword Rank Checker, which can be used to research platforms such as YouTube, Amazon, and Bing.

The keyword generator offers up to 150 ideas, including phrase match and question-based keywords, along with monthly search volume data and insights into keyword difficulty for top results.

Although not as comprehensive as paid services, these tools provide valuable insights. They include difficulty scores, estimated backlinks for ranking, and SERP analysis. The free suite efficiently manages various SEO tasks such as keyword research, link building, website audits, and monitoring rankings and traffic.

4. Semrush

Semrush provides detailed keyword data, making it ideal for those seeking advanced insights. The platform simplifies the process of analyzing SERP features and current search results.

Semrush offers a variety of keyword research tools, including content-focused keyword research, competitive keyword gap analysis, and Organic Traffic Insights. These tools provide more than just standard traffic and search volume data.

By linking with Google Analytics or Search Console, you can uncover ‘not provided’ keywords that would otherwise be hidden. The SEO Content Template tool helps create content by assessing it in real-time for readability, originality, tone, and SEO.

It provides guidance with a user-friendly bullseye graphic. However, the premium plans are expensive, although there is a fairly generous free plan that allows users to explore Semrush’s capabilities at lower usage levels.


Improving a website’s visibility and ranking on search engines is crucial and SEO plays a significant role in achieving this. To achieve this, users can utilize free keyword research tools if they have budget constraints.

We have discussed four such tools, and users can choose the one that suits their needs. However, it is essential to remember that an effective SEO strategy requires more than just keyword research. Strong content quality and a satisfying user experience are also crucial. To achieve greater SEO success, it is important to consider factors beyond just keyword research.
