Free tools
Free checks on one page or the whole site: speed, titles, links, sitemaps, AI crawlers, structured data, and the searches and rivals around them.
22 pages
One page of yours
- On-page SEO checkerPaste a URL and get the page read as a crawler reads it: title, description, canonical, indexability, headings, alt text, links, share tags, what to fix first.
- Title and meta description checkerPaste a page or type a title and a description: pixel widths, character counts, desktop and phone previews, with the h1 and canonical beside them.
- Social preview checkerPaste a URL and see the card a share produces on X, LinkedIn and Slack: the Open Graph tags read, the image fetched and measured, and what to fix first.
- Structured data checkerRead the JSON-LD on a page: every type, the rich result each can earn, the required and recommended fields it lacks, and a mended copy of each node.
- Server response checkerPaste a URL and time the server's answer: time to first byte, HTTP/2 or HTTP/3, brotli or gzip, Cache-Control, HSTS, the headers that decide when a page starts.
- Redirect checkerFollow a URL's redirects hop by hop: each status and destination, the time each took, the kind of hop, meta and script redirects, one rule to replace it.
- hreflang checkerPaste a URL and check its hreflang: the versions declared, whether the codes are ones Google reads, the self-reference, whether each version points back.
The whole site
- Core Web Vitals checkerPaste a URL for one Lighthouse run on a simulated phone: LCP, CLS, TBT and FCP against Google's thresholds, the biggest savings, the failing audits.
- Sitemap checkerRead a sitemap the way a crawler does: what it lists, how it is dated, whether robots.txt names it, and whether thirty of its addresses answer 200.
- Internal link checkerPaste your home page and get up to sixty pages fetched and their links read: the orphans, the pages sitting deepest, the least and most linked, links per page.
- Broken link checkerEvery link on one page, up to 150, fetched eight at a time: the ones that 404 with the words they carry, the ones that redirect and where to, as a list.
- robots.txt testerPaste a site, paths and a crawler: what its robots.txt allows by the rules Google reads with, the rule that decided each, why it won, and the file mended.
- AI crawler access checkerPaste a site or a page and see, crawler by crawler, whether it may read it: root and page, the rule that decides, the text without JavaScript, llms.txt.
- llms.txt generatorWrite an llms.txt from your site or from a few fields, in sections, and check the one a site already has against the proposal, link by link.
Searches and rivals
- SERP checkerType a search and see the results page as Google draws it now in six markets: the top ten sites, the People also ask questions, and who the AI Overview cites.
- Keyword volume checkerPaste up to twenty search terms and get the monthly searches for each in one of six markets, sorted, totalled, and ready to copy as CSV. No account, no card.
- Keyword ideas finderType one term and get up to fifty longer searches that contain it, with monthly demand, difficulty and intent, and a reading of the pattern.
- Backlink checkerType a domain and see how many sites link to it, how many only with nofollow, the spam score, and the twelve strongest linking domains. Free, no account.
- Click-through rate calculatorClicks and impressions to a rate, the typical range at your position, and the rows of a Search Console export ranked by the clicks they leave behind.
Write the file for you
- Schema markup generatorBuild the JSON-LD for an organisation, a product, an article, a FAQ, a how-to or a breadcrumb from a form, required fields marked and every value checked.
- robots.txt generatorBuild a robots.txt that says which AI crawlers may train on your pages and which may cite them, with the sitemap line and the paths closed to everyone.
- Title and meta description generatorPaste a page URL or a search phrase and get five titles under 60 characters and five descriptions of 120 to 155, written from the page, lengths counted.
