Crawling & technical audit
Moz Pro
Weekly Rogerbot crawls run at stated per-plan page limits with issue categories and severity, new issues flagged against the previous crawl by email, fix visibility, and Core Web Vitals analysed per tracked URL on a weekly re-check with 90 days of history — that part is genuine diagnosis, though the crawler sits in North America, which the vendor itself says can impact accuracy for international sites. Prioritisation is by issue type and frequency rather than traffic impact, and I found no public information on JavaScript rendering, log files, Search Console integration, indexation or canonical diagnosis, or structured-data validation.
Searchmetrics
The only site-health evidence is '24/7 always-on monitoring tracks how AI bots crawl your site. Real-time alerts and prioritized fixes' — a GPTBot alert feed, not an audit. No page limits, no JavaScript rendering, no Core Web Vitals, no indexation/canonical diagnosis, no log-file or Search Console comparison anywhere in the evidence, which puts this below even a basic link-and-tag crawler.
