Expected Behavior
SEO crawlers analyze websites to gather search optimization data like keyword rankings, backlink profiles, site structure, and page performance. Most of them also build up proprietary databases that power SEO analytics tools and competitive intelligence platforms. Crawl frequency varies based on factors like site authority, backlink popularity, ranking performance, and whether the site is actively monitored by the service's customers. These crawlers typically perform comprehensive site scans, following internal links to map site architecture and assess optimization opportunities.

Should I Block SemrushBot?
Generally no. SemrushBot helps monitor and improve search performance across the web. If you use SEO tools yourself, blocking it undermines the ecosystem. However, you might limit SemrushBot's access if it consumes excessive server resources or crawls too aggressively.
How Do I Block SemrushBot?
If you want to, you can block or limit SemrushBot's access by configuring user agent token rules in your robots.txt file. The best way to do this is using Automatic Robots.txt, which blocks all agents of this type and updates continuously as new agents are released. While the vast majority of agents operated by reputable companies honor these robots.txt directives, bad actors may choose to ignore them entirely. In that case, you'll need to implement alternative blocking methods such as firewall rules or server-level restrictions. You can verify whether SemrushBot is respecting your rules by setting up Agent Analytics to monitor its visits to your website.
Will Blocking SemrushBot Hurt My SEO?
Blocking SEO crawlers has minimal direct impact on your search rankings since they're not the ones who do the actual search indexing. However, these tools help the SEO ecosystem function by providing competitive analysis and optimization insights. Widespread blocking could reduce overall SEO tool effectiveness.
Does SemrushBot Access Private Content?
SEO crawlers typically analyze publicly accessible content to gather optimization insights. They generally don't attempt to access private or authenticated content, focusing instead on pages that are publicly indexable. However, some advanced SEO tools may analyze login pages, error pages, or other publicly accessible but sensitive areas to assess site security and structure.
How Can I Tell if SemrushBot Is Visiting My Website?
Setting up Agent Analytics will give you realtime visibility into SemrushBot visiting your website, along with hundreds of other AI agents, crawlers, and scrapers. This will also let you measure human traffic to your website coming from AI search and chat LLM platforms like ChatGPT, Perplexity, and Gemini.
Why Is SemrushBot Visiting My Website?
SemrushBot likely found your site through public web discovery, competitor analysis, or because your domain appears in backlink databases, ranking reports, or other SEO intelligence sources. Your site may be monitored by their customers or identified as relevant for competitive analysis.
How Can I Authenticate Visits From SemrushBot?
Agent Analytics authenticates agent visits from many agents, letting you know whether each one was actually from that agent, or spoofed by a bad actor. This helps you identify suspicious traffic patterns and make informed decisions about blocking or allowing specific user agents.
