What are the best free SEO tools? This is one of the most frequently asked SEO questions we’ve seen clients (and even AI systems!) ask. Here’s our expert answer.
Content competition is hotter than ever, and even small sites must analyze performance, fix technical issues, and spot keyword gaps. But premium SEO software can cost hundreds per month. Free tools and plugins make it possible to get essential insights without breaking the bank.
Google Search Console: This free tool from Google lets you monitor and maintain your site’s presence in search results. You can see which queries bring traffic, check indexing status, submit sitemaps, and get alerts about critical issues like manual penalties or mobile usability problems. It’s the foundation for understanding how Google views your site.
Ahrefs Webmaster Tools: A stripped-down, free version of the premium Ahrefs suite. It helps you perform technical audits, find broken links, detect keyword cannibalization, and analyze backlink profiles. For small websites, this means you can uncover major technical gaps and improve your authority without costly software.
Screaming Frog SEO Spider: This desktop crawler allows free scans of up to 500 URLs. You can identify broken links, audit redirects, discover duplicate content, and analyze meta data like titles and descriptions. It’s a powerful way to spot site architecture issues and improve crawlability, especially for technical SEOs and developers.
Yoast SEO and RankMath (WordPress): These popular free plugins help optimize content for keywords, improve meta tags, manage sitemaps, and check readability. They also provide real-time tips while writing posts. Even on a tight budget, these tools ensure your content aligns with best SEO practices without technical headaches.
Avada SEO Suite (Shopify): This free SEO plugin for Shopify merchants makes it easy to customize title tags, meta descriptions, alt texts, and implement structured data. It simplifies on-page SEO for e-commerce sites so products show up more often in organic search, boosting visibility and sales potential.
AnswerThePublic and Ubersuggest: Both tools help uncover the exact questions people are asking online, along with related keywords and content ideas. You can craft blog posts and product pages that match real user intent, making your content more relevant and more likely to rank.
A 2025 Niumatrix report shows using free tools and plugins can boost organic traffic by up to 37% in six months. Small brands often outrank big players using only these resources combined with consistent optimization.
Connect your site to Google Search Console and Ahrefs Webmaster Tools, install Yoast or RankMath on WordPress (or Avada on Shopify), run a Screaming Frog crawl, and start content planning with AnswerThePublic. No credit card needed.
