Description
From the marketplace listing
Website check for SEO, broken links and text errors. Give it a web address and it checks the page in a few seconds: title and meta description, headings, canonical and hreflang tags, structured data, image alt texts, security headers, and whether the site's robots.txt lets AI crawlers read it. For a whole site, the full check reads up to 20 pages from the sitemap, tests internal links for dead targets, finds duplicate titles and descriptions, noindex contradictions and thin pages, measures PageSpeed for mobile and desktop, and reviews the page text for spelling, translation and outdated-date errors. Every finding names the page or the rule it comes from, so you can fix it directly. Built for owners of small business websites and the people who run them, in German and English. Limits: public pages only, nothing behind a login, robots.txt is respected, at most 20 pages per check, reports are kept 90 days. It is not a security scanner.
Language: English · Automatically detected from descriptions.
