Create JSON-LD for 15 schema.org types — Organization, LocalBusiness, Article, Product, FAQ, Event, Recipe and more — with required-field checks.
Turn a verification code into the meta tag or DNS TXT record for Google Search Console, Bing, Yandex, Pinterest, Facebook, Baidu and Naver.
Create an RFC 9116 security.txt so researchers know how to report vulnerabilities — contacts, expiry, policy and languages checked.
Generate Apache .htaccess or Nginx rules for HTTPS, www or non-www, trailing slashes, 301 redirects, 404 pages, compression and caching.
Get title and meta description ideas for a keyword in five languages, with character counts — built from proven templates, not AI.
See how your title, URL and description may look in search results on desktop and mobile, with pixel-width estimates and cut-off warnings.
Find the most used words and phrases in your text, their density, and how often and how early your focus keyword appears.
See the status, every response header, compression and caching of a URL, and check HSTS, CSP, X-Content-Type-Options, frame protection and more.
Follow every redirect hop of a URL with status codes and timings, and check HTTP→HTTPS and www / non-www consistency.
Check a page’s title, meta description, headings, canonical, robots, hreflang, language, Open Graph, structured data, word count and images.
List every link on a page with its anchor text and rel values, count internal and external links, and spot empty or generic anchors.
Check the links on a page (or a list of URLs in Pro bulk mode) for 404s, server errors, redirects and unreachable hosts.
Find images without alt text, with meaningless file names, missing width and height, heavy files or old formats on any page.
Find http:// scripts, styles, frames, images and media on an HTTPS page that browsers block or warn about.
Check the viewport tag, zoom, responsive CSS and images, plugins, fixed-width elements and small fonts in a page’s code.
Measure time to first byte, HTML size, compression, HTTP version, render-blocking scripts, third-party hosts and page weight from the server.
See which CMS, framework, server, CDN, analytics, ads, payment and chat tools a website uses — with the evidence for each.
List the cookies a site sets before consent, with domain, lifetime, Secure, HttpOnly and SameSite flags and a likely purpose.
Validate JSON-LD on a page or pasted code: JSON syntax, schema.org context and required and recommended properties for common types.
Find the RSS, Atom or JSON feeds of a website and validate one: required fields, dates, links, duplicate IDs and latest items.
Validate an XML sitemap or sitemap index and count its URLs, generate a sitemap from a URL list, or split a large one into files and an index.
Validate a site’s robots.txt, test whether a path is allowed for a crawler (AI bots included), or generate robots.txt and llms.txt files.
Compare two pages and see how similar their main text is, whether titles and descriptions match, and how their canonical tags handle it.
Check that your business name, address and phone are the same on up to five pages — read from schema.org, microdata and tel: links.
Look up A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records, compare public resolvers, and check SPF, DMARC and DNSSEC.
Look up an IP address or domain: version and type, reverse DNS, network owner, range, registry country and abuse contact.
Check a site’s TLS certificate: trust, host-name match, issuer, expiry and days left, key, signature, protocol, cipher and chain.
See when a domain was registered, its age, expiry date, registrar, status, transfer lock, DNSSEC and name servers from official RDAP data.
Crawl your site from a start page and find errors, missing or duplicate titles and descriptions, H1 problems, thin, slow and noindex pages.
