Updated October 28, 2026. “Free” means a free plan or free tier exists; limits change, so check each tool before relying on it.
Free SEO tools, in short: Google Search Console is the one free SEO tool every site needs, because it shows what Google actually indexes and which searches bring you clicks. Add PageSpeed Insights for speed, the Rich Results Test for schema, a crawler such as Screaming Frog (free up to 500 URLs) for technical issues, and Google Trends plus Keyword Planner for research. With Ahrefs Webmaster Tools and Bing Webmaster Tools you can run a complete SEO workflow without paying.
How we chose these tools
We use several of these on BrandMag, including Search Console, Analytics, PageSpeed Insights and Rank Math. The list favors tools that use first-party data from search engines, have a free tier that is genuinely useful rather than a trial, and cover a different job each. We left out tools whose free plans are too limited to do real work.

How to use them together
Weekly
- Search Console Performance: which queries and pages gained or lost clicks.
- Search Console Pages: any new indexing errors.
Monthly
- Crawl the site with Screaming Frog or Ahrefs Webmaster Tools and fix broken links and redirect chains.
- Check Core Web Vitals in Search Console and PageSpeed Insights for your main templates.
- Review Bing Webmaster Tools; Bing data also feeds some AI assistants.
Before writing a new article
- Use Google Trends and Keyword Planner for demand, and AlsoAsked for the questions to answer.
- Search the topic yourself and note what the top results miss.
After publishing
- Validate schema with the Rich Results Test.
- Request indexing in Search Console with URL Inspection, once; resubmitting repeatedly does not help.
Tools to avoid or treat with caution
- “Instant indexing” plugins using Google’s Indexing API for normal pages. Google reserves that API for job postings and livestreams and runs spam detection on submissions. See our technical SEO audit checklist.
- Traffic bots and “CTR manipulation” services. They inflate analytics, distort decisions and can put an AdSense account at risk.
- Third-party volume numbers taken as exact. Use them to compare keywords, not as forecasts.
Bottom line: Start with Google’s own free SEO tools, then add others only to fill gaps. A small stack of free SEO tools used every week beats a long list of free SEO tools you never open.
