Crawling & technical audit
Ryte
The crawler clearly exists — 'Löse technische Website-Fehler effizient' and Web Performance are pillars of the whole WUX pitch — but no page cap, crawl schedule, JavaScript rendering or issue prioritisation is stated anywhere. That is above 'no crawler' and below the anchor where a real limit and rendering are documented.
Semrush
The Site Audit engine is real: documented modules for crawlability and indexability, canonicals, structured data, mobile parity and rendering, Core Web Vitals judged against Google's published good and poor bounds at the 75th percentile, Search Console data referenced in the workflow, and multi-million-page crawling on the Enterprise tier. We found no public information on log-file analysis, regression detection between crawls, or whether issues are prioritised by traffic impact rather than count — the captured pages promise a prioritized fix list without stating the ranking basis. Strong enough to bill clients against, a step short of diagnostic.
