SiteAuditBot is a bot in the SEO crawlers category, operated by Semrush.
Check for over 130 common website issues and get special reports about your site’s crawlability, use of markups, internal linking, speed/performance, HTTPS, and international SEO.
SEO crawlers map links, keywords and technical issues for SEO tools and backlink databases. They help the tool's customers, often your competitors, rather than you. Rate limit or block the ones you do not use.
Sample user agent strings sent by SiteAuditBot:
Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25 (compatible; SiteAuditBot/0.97; +http://www.semrush.com/bot.html)Mozilla/5.0 (compatible; SiteAuditBot/0.97; +http://www.semrush.com/bot.html)Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
SiteAuditBot follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
User-agent: SiteAuditBot Disallow: /
User-agent: SiteAuditBot Disallow: /private/ Disallow: /search
User-agent: SiteAuditBot Allow: /blog/ Disallow: /
User-agent: SiteAuditBot Allow: / User-agent: * Disallow: /
User-agent: SiteAuditBot group, SiteAuditBot ignores your User-agent: * rules, so repeat any that should still apply.SiteAuditBot from SiteAuditBot's user agent; check Semrush's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
SiteAuditBot works for an SEO tool's customers, often your competitors. It adds server load without readers, so rate limit or block it unless you use the tool.
Transfon Security for publishersSEO crawlers map landing pages and links for competitor research. Keep SiteAuditBot's visits out of campaign data.
Transfon Security for advertisersSiteAuditBot can map your catalogue, prices and site structure for competitors. Block it unless you use the tool yourself.
Transfon Security for e-commerceAllow SiteAuditBot only if your team uses the tool; otherwise rate limit it on docs and marketing pages.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement.

Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Yes. SiteAuditBot follows robots.txt, so a Disallow rule for the SiteAuditBot user agent stops it from crawling the paths you list.
Add "User-agent: SiteAuditBot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "SiteAuditBot" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so SiteAuditBot may not follow it, and anyone can send SiteAuditBot's user agent, so a fake SiteAuditBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
