SEO Tools Centre is a free collection of 100+ online tools for writing, search engine optimisation and running a website. You can paraphrase and proofread text, research keywords, check how a page appears in Google and AI search, test a site's speed and convert PDF and image files, all without signing up.
SEO Tools Centre is run by Ahmad Shahzad Sanmal, an SEO specialist who provides off-page SEO and link-building services to clients. He looks after the tools, writes and reviews the guides and handles the site's day-to-day running. SEO Tools Centre has been online since 2016 and is maintained independently.
Because the tools come out of real client SEO work, they focus on the checks people need most often: what a page looks like in search results, whether search engines and AI crawlers can read it, and whether the text is clear and original.
Most SEO and writing tasks need a quick, single-purpose tool: count the words in an essay, check a meta description, merge two PDFs, see whether a page is blocked from AI search. Many sites that offer these tools hide them behind sign-ups, limits or cluttered pages. SEO Tools Centre keeps them free, fast and in one place, with a plain guide on every page.
SEO Tools Centre is free to use and is supported by advertising. Ads never change a tool's results, and no company pays to be recommended in our guides. You can read how we handle data and cookies in our Privacy Policy.
You can also find and review SEO Tools Centre on SaaSHub and AlternativeTo.
