Best Free SEO Tools in 2025

Having covered the basics, it’s time to look at the top free SEO software available on the modern market. Check out the list below, read about each tool’s features, advantages, and disadvantages, and single out the ones that appeal to you the most.

1. Ahrefs

Ahrefs is a popular search engine optimization package software with a free plan. It tops our SEO tools list for the sheer amount of capabilities it offers without a price tag. You’ll benefit from it the most if you use it for:

• Keyword research and generation
• Keyword rating analysis
• Backlink checking and tracking

The software works well across multiple platforms, so you won’t have to search for separate free SEO tools for YouTube, Google, Amazon, and other brands. Ahrefs will give you insights into your ranking per keyword, provide info on keyword volumes, and identify both healthy and broken links across the board.

This SEO tool’s primary downside is the limit it imposes on free-plan users. Its limited-use Webmaster Tools make for a great start but won’t be sufficient for brands with more complex needs.

2. Semrush

Semrush is another well-known tool among experienced digital marketers. While it offers the most value within its paid plans, there are still plenty of fantastic features users can take advantage of for free, such as:

• Its  SEO ranking software free capabilities
• Its content and technical site audits 

Semrush offers a specialized rank checker that can track your search rankings for up to 10 keywords a day for free. It can also perform a complete analysis of your site, evaluating its content and technical structure. Through these assessments, it aims to generate SEO-based recommendations, from keyword-geared content briefs to writing pointers.

The main drawback of Semrush is that many of its unique features are only available to paid accounts. Making its Share of Voice or Trends Analytics for Reddit functions complimentary would’ve elevated it to the level of the best free SEO tools for Reddit, Facebook, LinkedIn, and other famous social media platforms. However, with plans starting at $129.95 per month, it’s too expensive for those just starting out. 

3. Google Search Console

Google’s Search Console is on par with Semrush, which is hardly surprising considering what it offers. This free-to-use website has an integrated analytics tool that scores your website’s performance according to Google Search results across numerous categories. We recommend using it to learn:

• Your best-ranking keywords
• Click-through rates
• What technical issues hold your site from growing

Moreover, Google Search Console allows you to submit XML sitemaps and individual URLs. It’ll scan, monitor, and troubleshoot your search engine visibility, providing insights into your traffic volumes, rankings, indexing status, and any underlying issues.

It's undoubtedly one of the best free SEO tools for WordPress, Webflow, Shopify, Squarespace, and other popular platforms. However, it won't provide any results for search engines other than Google. If you're looking for a more comprehensive tool, you might need to choose something else.

4. Google Analytics

If you’re not new to the industry, you know many modern marketers swear by Google Analytics. It is one of the best SEO optimization free tools, offering the most in-depth and detailed reports on your website performance. Think of it as the perfect addition to Google Search Console, completing your website analysis with data on your user behavior and traffic sources.

All you need to do is incorporate its HTML code into your website’s code, and you can start tracking all traffic in real time, according to:

• Its origins
• Whether it’s organic, direct, or paid
• Pages it’s targeting the most
• Demographics
• What user interactions it encompasses

Some users find Google Analytics challenging due to its steep learning curve. The tool's extensive functionality and wealth of information can be overwhelming for beginners. Additionally, no customer support is available for those using the free search engine optimization software version. 

5. AnswerThePublic

This software doesn’t enjoy the same popularity as some of its predecessors, but it is still a great tool for marketers looking to optimize their content.

These analytics are a fantastic resource, whether you’re generating new content or enhancing what you already have. They can also help you gain a better understanding of your audience and individual user search intent.
