SHOWING 32 OF 32 TOOLS

AI visibilityAgent readiness checkScore how readable your site is to AI agents: crawler rules, sitemap, llms.txt, Link headers and the well-known descriptors they look for.
AI visibilityAI crawler checkerWhich AI crawlers can actually read a page. Real robots.txt group precedence for eleven tokens, what each one controls, and whether the page needs JavaScript.
AI visibilityAnswer readiness scoreHow quotable a page is inside an AI answer: the opening paragraph, question-shaped headings, lists, tables, an FAQ block, sources and a date.
AI visibilityAI content extractorSee a page as a text-only crawler sees it: navigation and scripts stripped, main content shown, word count and surviving headings listed.
AI visibilityStructured data for AIWhich structured data an AI answer engine can use here: who publishes this, what the page is, and which facts it may state.
AI visibilityllms.txt generatorRead your sitemap and homepage and draft an llms.txt: the map an AI reads to work out what your site is for. Edit it before you copy.
AI visibilityllms.txt validatorCheck an existing llms.txt against the spec at llmstxt.org, line by line, and fetch its links to find the dead ones.
Crawling and indexingRobots.txt generatorBuild a robots.txt and decide which AI crawlers can read your site, with what each block costs you spelled out. Runs in your browser.
Crawling and indexingRobots.txt testerIs this path crawlable by this bot. Real precedence: specific groups beat the wildcard, longest pattern wins, Allow takes a tie.
Crawling and indexingSitemap checkerFind your sitemap the way a crawler does, then check what is inside it: valid entries, working URLs, and a lastmod that means something.
Crawling and indexingRedirect checkerTrace the whole 301, 302, 307 and 308 chain for a URL. Every hop and status code, with loops, over-long chains and https downgrades flagged.
Crawling and indexingBroken link checkerRead the links on a page and request a spread sample of up to 25 to find the ones that lead nowhere. A sample of one page, and it says so.
Crawling and indexingCanonical tag checkerDoes your canonical match the URL you land on after redirects, does it point at itself, is it absolute, and is the page it names real.
Structured dataSchema markup validatorPaste JSON-LD or point us at a page. Reports which schema types are there and which fields Google's own documentation requires that are missing.
Structured dataFAQ schema generatorQuestion and answer pairs in, valid FAQPage JSON-LD out, with an honest note on what Google still does with FAQ markup.
Structured dataArticle schema generatorArticle, BlogPosting or NewsArticle JSON-LD with the author, dates, images and publisher Google recommends.
Structured dataHowTo schema generatorSteps, supplies, tools and total time in, HowTo JSON-LD out, with minutes converted to the ISO 8601 duration schema.org needs.

Structured dataBreadcrumb schema generatorYour page hierarchy in, BreadcrumbList JSON-LD out, positions numbered and the last crumb handled the way Google documents.
Content and metaMeta previewSee your page as a Google result and as a shared link, with character counts and live editing.
Content and metaTitle tag generatorWrite a title and watch its real pixel width against Google's ~600px desktop cutoff, measured by rendering it rather than counting characters.
Content and metaWord counter and readabilityWords, characters, sentences, paragraphs and reading time, plus a real Flesch-Kincaid grade with a syllable count that is explained rather than hidden.
Content and metaKeyword density checkerTerm frequency and density for one, two and three word phrases, with the stopword list published in full instead of hidden.
Content and metaURL slug generatorTitles to clean slugs, one line each. Handles accents properly, including the letters that plain Unicode stripping would delete.
Content and metaHTML to markdownPaste HTML, get clean markdown. Headings, lists, links, tables and code blocks, converted by your browser's own HTML parser.
Content and metaUTM campaign URL builderBuild a tagged campaign URL and catch the mistakes that quietly split your reports: capitals, spaces and a missing campaign name.
Domain and networkDNS lookupEvery record a resolver can see for your domain, with the TTL on each one: A, AAAA, CNAME, MX, NS, TXT and SOA.
Domain and networkDNSSEC checkerIs DNSSEC switched on for your domain, and does the signature chain still validate? Those are two different questions, and this answers both.
Domain and networkSSL certificate checkerWho issued the certificate, when it expires, how many days are left, and whether the chain a browser walks leads somewhere trusted.
Domain and networkIP lookup and reverse DNSResolve a hostname to every address it has, then check whether each address points back at a name that resolves back to it.
Domain and networkSPF, DKIM and DMARC checkerThe DNS records that decide whether your mail arrives and whether anyone else can send as you, with your SPF record's real lookup cost counted.
Domain and networkHTTP header checkerEvery response header from a URL, scored on transport, browser safety, caching and crawlability, with a plain line on what each one does.
