Why track SiteAuditBot traffic?
Control third-party crawl impact on your server. SiteAuditBot crawls your site to build Semrush's SEO database. While useful for competitive analysis, these crawlers can consume significant server resources on large sites.
Identify who's analyzing your site. SiteAuditBot visits reveal when competitors or agencies are running audits on your domain.
Manage crawl priority. If SiteAuditBot is consuming crawl budget you'd rather allocate to search engines, you can throttle or block it based on measured volume.
Surface 4XX and 5XX errors before search engines find them. If SiteAuditBot reports broken pages or server errors in its crawl data, you can fix those issues proactively — before search engine crawlers encounter them and your rankings suffer.
Is SiteAuditBot worth the server resources?
SiteAuditBot crawls your site to build Semrush's SEO database. Unlike search engines, this crawler doesn't send you any referral traffic — it feeds a third-party tool.
That's not necessarily a problem — Semrush's data may power tools you use yourself. The question is whether SiteAuditBot's crawl volume is proportionate to its value.
