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and thin pages, measures PageSpeed for mobile and desktop, and reviews the page text for spelling, translation and outdated-date errors.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.

SEO, Links und Textfehler Website-Check für SEO, tote Links und Textfehler. Gib eine Webadresse ein, und die Seite wird in wenigen Sekunden geprüft: Titel und Meta-Beschreibung, Überschriften, Canonical- und hreflang-Tags, strukturierte Daten, Alt-Texte von Bildern, Sicherheits-Header und ob die robots.txt der Website KI-Crawler lesen lässt. Für eine ganze Website liest der vollständige Check bis zu 20 Seiten aus der Sitemap, testet interne Links auf tote Ziele, findet doppelte Titel und Beschreibungen, noindex-Widersprüche und dünne Seiten, misst PageSpeed für Mobil und Desktop und prüft den Seitentext auf Tippfehler, Übersetzungsfehler und veraltete Daten. Jeder Befund nennt die Seite oder die Regel, aus der er stammt, damit du ihn direkt beheben kannst. Gebaut für Inhaber kleiner Firmenwebsites und die Leute, die sie betreuen, auf Deutsch und Englisch. Grenzen: nur öffentliche Seiten, nichts hinter einem Login, robots.txt wird respektiert, höchstens 20 Seiten pro Check, Berichte werden 90 Tage aufbewahrt. Kein Sicherheitsscanner.
