Crawling & technical audit
Ryte
The homepage claims you can 'löse technische Website-Fehler effizient', so a crawler exists in name, but nothing on page scale, rendering, severity, Core Web Vitals or prioritisation — the evidence is silent everywhere the 3-and-up anchors get specific. I couldn't commission an audit remediation piece off a slogan.
Semrush
The Site Audit scope is real and broad — crawlability and indexability, redirects, Core Web Vitals judged against Google's good, needs-improvement and poor values at the 75th percentile, canonicals, structured data and internal linking — with crawl snapshots, a stated prioritised fix list, and rendered-browser checks in the fallback path. I found no public information on log-file analysis, crawl budget work, or regression detection between crawls with deploy attribution, which is what separates a diagnostic from a very good checklist.
