🤖 Overview

SeoSiteCheckup is a legitimate SEO analysis tool operated by SEOSiteCheckup Inc., a company based in the United States that provides free and paid website auditing services. Its primary purpose is to crawl individual web pages or entire sites on-demand at user request to evaluate technical SEO factors such as page speed, meta tags, heading structure, broken links, and mobile-friendliness. Unlike search-engine crawlers, this bot does not build a public index but instead delivers real-time diagnostic reports directly to the requesting user through the SeoSiteCheckup.com interface.

🌐 Technical Behavior

The SeoSiteCheckup crawler follows an on-demand model: it only fetches pages when a user explicitly triggers an audit from the tool’s web interface or API. According to the company’s official support page (https://seositecheckup.com/faq), the bot typically makes between 1 and 10 requests per audit, depending on the depth of analysis requested (e.g., single-page scan vs. multi-page crawl). The crawler uses HTTP/1.1 and defaults to the user-agent string SeoSiteCheckup/1.0 (also reported as SeoSiteCheckup or SeoSiteCheckupBot). It identifies itself via the User-Agent header and does not spoof other common bots. IP ranges are associated with cloud providers such as Amazon Web Services or Google Cloud, though exact blocks are not publicly documented. Requests are sent from a small set of subnets to facilitate rate limiting by webmasters. The bot does not follow JavaScript rendering unless specifically enabled via the tool’s “advanced” settings, and it respects standard HTTP caching directives such as Cache-Control and Last-Modified.

📋 robots.txt Compliance

SeoSiteCheckup explicitly states on its FAQ page that its crawler honors robots.txt Disallow directives. If a webmaster blocks SeoSiteCheckup in their robots.txt file, the tool will not crawl the disallowed paths and will return an error or warning in the audit report. Documentation at https://seositecheckup.com/robots-txt confirms that the bot checks robots.txt before every crawl session and caches the file for a short period (typically 30 minutes) to avoid redundant fetches.

🔍 Detection Indicators

Administrators can identify SeoSiteCheckup traffic by inspecting server logs for the User-Agent string SeoSiteCheckup/1.0 or SeoSiteCheckup. Some versions also include the header From: [email protected] as a contact address. The bot typically does not set custom HTTP headers beyond standard ones. Because audits are user-initiated, the referer header may contain the SeoSiteCheckup domain (e.g., https://www.seositecheckup.com) when the crawl is triggered from the web interface. The IP address often belongs to a known cloud provider range, which can be cross-referenced against published lists of SEO tool IPs.

📊 Data Usage

All data collected by SeoSiteCheckup is used exclusively for generating the requested SEO audit report. The tool does not store crawled content long-term or use it for any AI training, search indexing, or resale. According to the company’s privacy policy (https://seositecheckup.com/privacy), audit results are retained temporarily (usually 30 days) to allow users to revisit reports, after which the raw data is deleted. No aggregation across multiple audits occurs, and the company does not build user or site profiles beyond analytics for service improvement.

⚙️ Rate Limiting Policy

While SeoSiteCheckup is not malicious, its on-demand nature can appear aggressive if a single user triggers multiple sequential audits — the bot may send 10–50 requests in under a minute to the same domain during a deep crawl. Rate limiting is justified to prevent accidental load on origin servers; webmasters should throttle access from the known user-agent string or block it entirely if the tool is not needed, while being aware that this will prevent legitimate SEO diagnostic reports from being generated.
