Free SEO tools for keywords, content, links and technical checks
Last reviewed and updated
ToolForge is a collection of 90+ free SEO tools grouped by the job you need done: finding keywords, writing and tagging pages, fixing technical issues, auditing backlinks and page authority, and measuring speed. Nothing here asks for an account.
The six sections below follow the order a real optimisation pass takes. Work through them once for a new site, then repeat the technical, link and freshness checks on a schedule.
Track the results, not just the fixes
Open the free SEO dashboard to log keyword positions, monitor referring domains and score any page live — then follow the SEO guide or run the SEO checklist before you publish.
1Free keyword research tools
Keyword tools tell you which phrases people actually type before they buy, book or sign up. Start broad, then narrow down to long-tail variants where competition is realistic for a newer site.
Pair volume with intent: a phrase with 200 searches from buyers beats 5,000 searches from casual browsers.

2Free on-page and meta tag tools
On-page SEO is the part you fully control. Every page needs one unique title, one meta description, one H1, and clean social preview tags so shared links look deliberate.
Generate the tags rather than hand-writing them — it keeps character counts inside search-result limits and prevents duplicated markup.

3Free content and writing tools
Search engines reward pages that answer a question completely. Check length, readability and repetition before you publish, and rewrite anything that reads like filler.
Thin pages and duplicated paragraphs are the two most common reasons a well-optimised page still fails to rank.

4Free technical SEO tools
Technical SEO decides whether your content is discoverable at all. Sitemaps and robots.txt guide crawlers, redirects preserve link value, and HTTPS is a baseline expectation.
Crawl your own site the way a bot does — broken links and redirect chains are invisible in a browser but obvious to a crawler. Internal links matter here too: a page nothing links to receives almost no crawl priority or authority, however good it is.

5Free backlink and page authority tools
Backlinks remain among the strongest ranking signals Google uses, and page authority is largely a function of how many relevant domains link to a URL and how your own internal links distribute that value. Audit which domains link to you, how they anchor those links, and whether the profile looks natural.
Compare your referring domains with competitors to find realistic outreach targets instead of guessing, then point internal links from your strongest pages at the ones you want to rank. Recheck monthly: lost links are the quietest cause of a ranking drop.

6Free speed, freshness and monitoring tools
Speed and mobile usability are ranking factors and conversion factors at once. Test the pages that receive the most traffic first, then optimise the heaviest assets.
Content freshness belongs in the same routine: re-audit your top pages quarterly, update anything with dated figures, and confirm the updated version is reindexed. A page that isn't indexed or isn't reachable can't rank at all.
