SemrushBot
Semrush's SEO crawler for competitive analysis and backlink tracking.
What is SemrushBot?
SemrushBot is the web crawler for Semrush, a leading SEO and digital marketing tool platform. It crawls the web to build Semrush's databases for keyword research, backlink analysis, site auditing, and competitive intelligence features.
The crawler respects robots.txt and identifies itself clearly. Semrush provides verification tools for authenticating genuine SemrushBot requests. Like other SEO crawlers, it provides no direct ranking benefit but builds Semrush's commercial data products.
SemrushBot crawl rates are moderate and generally less impactful than AhrefsBot. However, for smaller sites, cumulative SEO crawler traffic (Ahrefs + Semrush + Moz + Majestic) can be noticeable.
User-Agent Strings
These are the known user-agent patterns used by SemrushBot. Use them to identify this crawler in your server logs or configure robots.txt rules.
robots.txt example:
User-agent: SemrushBot Disallow: /private/ Allow: /
