Free Keyword Research Tools
Now let’s explore SEO tools by category. There are plenty of high-quality free tools available, so it would be a waste to mention only the highlights.
These are designed to provide you with a solid understanding of your keywords and what you should target.
Google Trends

Google Trends displays the popularity of search queries over specific periods. It’s great for performing keyword research on emerging topics, as traditional professional tools like Ahrefs and Semrush may not yet have data on them.
However, I should note that Google Trends isn’t the best source for most keyword research. It can provide an overview or quick comparison of metrics, but for serious research, you should consider keyword difficulty metrics from reliable tools.
Google Keyword Planner

Google Keyword Planner is a tool within Google Ads that helps marketers research and identify keyword opportunities. It offers insights into search volumes, keyword competitiveness, and potential CPC. It’s great for those who only need occasional or casual keyword research, as the data is limited and much broader compared to other options, making it less informative.
Ahrefs Free Tools

Ahrefs offers many free tools that are helpful for small projects and one-off bits of research. While the platform’s main tools are paid, their free solutions provide simple yet effective ways to improve SEO.
Free SEO Audit Tools
These will help you discover problems with your site that might be broken or causing SEO issues.
Ahrefs Webmaster Tools
Ahrefs Webmaster Tools is a somewhat hidden offering, even for seasoned SEO professionals. While Ahrefs requires a paid account for most keyword research, it offers free webmaster tools for those looking to improve their content and fix technical issues.
Woorank

This tool covers areas such as meta descriptions, keyword usage, mobile responsiveness, sitemap validity, and even social media integrations.

By entering a URL, you can get a comprehensive report detailing the site’s performance metrics, such as fully loaded time, total page size, and the number of requests made. The platform provides insights based on key performance indicators and visualizations, such as waterfall charts, which break down the load order and timing of each element.
