CrawlGenius Log Analyzer

CrawlGenius Log Analyzer examines server logs to show how search engines and AI crawlers interact with websites. Its SEO analysis can surface crawl budget waste, HTTP errors, orphan pages, redirect and canonical issues, and fake bots. It tracks AI and LLM crawlers separately from Googlebot and offers 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 provided through a WordPress plugin, server agent, file upload, Amazon S3, or FTP/sFTP deposit; FTP/sFTP is not available on the Free plan. Paid plans include a REST API and MCP server. The pricing page says the service checks AI crawlers against more than 3,500 official IP ranges and rejects spoofed hits at ingestion. The company says data is hosted in the EU, processed under GDPR, and stored after visitor IP addresses are truncated. It does not currently hold SOC 2 or ISO 27001 certification. The Free plan is €0.00 per free and includes 10,000 log lines monthly, one project and a seven-day visible window. Starter is €49.00 per month and Agency is €149.00 per month, both excluding VAT. A guided 30-day trial requires no credit card or commitment.

CrawlGenius focuses on log-based visibility into search and AI crawler behavior, with a free tier and paid automation options. Readers should weigh its retention and plan limits, as well as the absence of keyword rankings, backlink data and outbound webhooks.

It suits SEO professionals who want to inspect crawler activity, log coverage and crawl waste. Teams needing automation can consider paid plans, which include an API and MCP server.

CrawlGenius Log Analyzer turns server logs into focused reporting on search-engine and AI-crawler activity. It is best suited to SEO professionals diagnosing crawl behavior across a site or portfolio. Its crawler-specific diagnostics are the draw; its modest free allowance and paid volume limits make scale an important buying consideration.

Overview

The analyzer surfaces crawl budget waste, HTTP errors, orphan pages, redirect and canonical issues, and fake bots. Dashboards follow crawl coverage, freshness, time to first visit, new URLs, and URLs crawled but never clicked. That makes it useful for investigating how bots discover and revisit pages, but not a replacement for a broader SEO suite.

AI and LLM crawlers are separated from Googlebot, and the product offers comparisons between AI and SEO activity. CrawlGenius says it checks AI crawlers against more than 3,500 official IP ranges and rejects spoofed hits during ingestion. That distinction can make bot-traffic analysis more meaningful. The product does not include keyword rankings, backlink data, or outbound webhooks, so teams needing those capabilities will need other tools.

Key features

Logs can arrive through a WordPress plugin, server agent, file upload, Amazon S3, or FTP/sFTP deposit; FTP/sFTP is excluded from Free. Paid plans add a REST API and MCP server, opening up automation that the free tier lacks. Crawler segmentation and crawl-waste reports support the core diagnostic use case.

Data is hosted in the EU and processed under GDPR, with visitor IP addresses truncated before storage. CrawlGenius does not currently hold SOC 2 or ISO 27001 certification, a relevant limitation for organizations that require either credential. Paid plans include 13 months of history, while 90-day and three-year retention options are also listed.

Pricing

The pricing note gives a free plan, paid access from €44.10/mo, and a 30-day trial. Plan prices are stated separately in EUR excluding VAT: Starter is €49 a month and Agency is €149 a month, both billed monthly without commitment, with a 10% discount for annual commitment. The difference between the “from” figure and the listed Starter price makes it worth confirming the applicable price before subscribing.

• Free — free: 10,000 log lines per month, one project, and a seven-day visible window. It is a low-risk way to assess the analysis, but the short window and small quota constrain ongoing monitoring; FTP/sFTP, the REST API, and MCP server are not included.
• Starter — €49 a month: One project, 250,000 log lines per month, 13 months of history, and an optional crawler module. This suits an individual site needing longer-term visibility, though the single-project cap and optional crawler module narrow its appeal for multi-site teams.
• Agency — €149 a month: Unlimited projects and 500,000 log lines per month aggregated, with additional volume priced by tier. It fits agencies managing multiple properties, but the shared quota means larger portfolios may incur extra costs.
• Enterprise — custom pricing: For more than 20 million lines per month or more than 50 projects, with custom volumes and retention. A dedicated customer success manager is included.

The guided 30-day trial analyzes a customer's real logs and requires no credit card or commitment. The founder provides onboarding, training, and technical SEO advice, which can help teams get value from a specialized tool; Enterprise adds a dedicated customer success manager.

Platforms

CrawlGenius is web-based. Its EU hosting and IP truncation may suit teams attentive to data handling, while the absence of SOC 2 and ISO 27001 certification may rule it out for buyers with those requirements.

Who it's for

This is a focused choice for SEO professionals who need to investigate crawler behavior, waste, and URL discovery using server logs, especially when separating AI crawler activity from Googlebot matters. It is less suitable as a standalone answer for teams seeking rankings, backlinks, outbound webhooks, or generous multi-project volume at the entry price.

Pros and cons

• Pros: Separates AI crawlers from Googlebot and compares AI with SEO activity; verifies AI crawler identities against more than 3,500 official IP ranges; provides useful URL and crawl diagnostics; offers a no-card, no-commitment trial on real logs.
• Cons: Free is limited to 10,000 lines a month, one project, and seven days; Starter is capped at one project and makes crawler analysis optional; Agency's 500,000-line allowance is aggregated; rankings, backlinks, and outbound webhooks are absent; SOC 2 and ISO 27001 certification are not held.

Alternatives

For a broader starting point, browse SEO Log File Analysis Tools. Consider these alternatives if their access model, platform, or stated limits better fit your work:

• LogLens offers a free web, API, and self-hosted option with 500K requests per month, one website, and 30 days of history; choose it when that allowance and deployment range are a better fit.
• SEOMER combines quick page checks and limited daily usage on its free plan with paid token top-ups; consider it when that usage model suits you better than log-line-based plans.
• SEO Log Auditor is an open-source, MIT-licensed tool that runs locally; choose it if local execution is the priority.
• AuditLabs SEO Log File Analyzer comes from SEO practitioner Antonio Maculus, Director of AI Content Strategy at Better Collective, and has a Supporter plan at $7.99 a month; consider it if that option better matches your needs.
• Crawl Lab is free, requires no sign-up, and has no server-side size limit; it is worth considering if those constraints matter most.
• Log File Bot Traffic Cost Analyzer offers browser triage under 500 MB, exact CLI analysis for 500 MB–50 GB, and BigQuery for 50 GB+; choose it if that size-based workflow is a better fit.
• Nirengi Log Analyzer is free for macOS 14.4 or later, with no subscription or in-app purchase; consider it if you use a compatible Mac.
• Patrick Stox Log File Analyzer is free, needs no sign-up, accepts multiple files, and streams large logs in chunks; choose it if those file-handling terms suit you.

Verdict

Choose CrawlGenius if you are an SEO professional who needs detailed log-based crawl diagnostics and a distinct view of AI crawler traffic. Its verified crawler segmentation, URL dashboards, and longer paid retention make that case compelling. Look elsewhere if you need a full SEO suite, formal SOC 2 or ISO 27001 certification, or higher project and log-line allowances without stepping into custom pricing.
