Crawling & technical audit
Moz Pro
Weekly crawls at published page limits per plan, severity-tiered issue categories with "Moz Recommends Fixing" guidance, and per-URL Core Web Vitals scored on Lighthouse weighting match the mid-tier package. Issues are prioritised by type and frequency rather than traffic impact, and the pages state the crawlers are based in North America, "which can impact accuracy and performance for international sites". I found no public information on JavaScript rendering, log-file or Search Console comparison, or structured-data validation.
Searchmetrics
Everything audit-shaped here is "24/7 always-on monitoring" of AI bots with "real-time alerts and prioritized fixes" — a bot-watch feed, not an audited crawl. No page limit, no JavaScript rendering, no Core Web Vitals, no indexation or canonical diagnosis appears anywhere; even the broken-links-and-missing-tags baseline of the 3-anchor is unevidenced, and the prioritisation claim is the only thing keeping it above 0.
