In their own words
CrawlGenius Log Analyzer
CrawlGenius Log Analyzer analyzes server logs to show how search engines and AI crawlers interact with a website. Its SEO analysis identifies crawl budget waste, HTTP errors, orphan pages, redirect and canonical issues, and fake bots. AI and LLM crawlers are tracked separately from Googlebot, with comparisons between AI and SEO crawling. Dashboards cover crawl coverage, freshness, time to first visit, new URLs, and URLs crawled but never clicked.
Logs can be supplied through a WordPress plugin, server agent, file upload, Amazon S3, or FTP/sFTP deposit; FTP/sFTP is unavailable on the Free plan. Paid plans include a REST API and MCP server. The pricing page says AI crawlers are checked against more than 3,500 official IP ranges and spoofed hits rejected at ingestion. The company says data is hosted in the EU, processed under GDPR, and visitor IPs are truncated before storage; it does not currently hold SOC 2 or ISO 27001 certification. The web-based product is aimed at SEO professionals. The Free plan is free and covers 10,000 log lines monthly, one project, and a seven-day visible window. Starter is €49 a month and Agency is €149 a month, excluding VAT. A guided 30-day trial uses real customer logs and requires no credit card or commitment.
Screaming Frog SEO Log File Analyser
Screaming Frog SEO Log File Analyser is a desktop application for examining access logs and understanding search engine and AI bot activity. It installs locally and keeps log event data in a local database. It accepts Apache, W3C Extended, and Amazon Elastic Load Balancing logs, and can verify supported bots to identify spoofed requests. Reports cover crawled URLs, crawl frequency, response errors, redirects, bytes downloaded, and response times. Users can match imported data containing a URLs column against log activity, including crawls, directives, or external link data. Log files can be added by drag and drop, with analysis exported to CSV or Excel. The software can process millions of events, though capacity depends on hard drive space. It runs on Linux, macOS, and Windows. The free plan allows 1,000 log event lines and one project. The paid licence costs $139 per year and includes unlimited events and projects, subject to storage capacity. Free technical support is listed for both versions.
