CrawlGenius Log Analyzer

CrawlGenius Log Analyzer is a web-based server-log analysis tool for SEO professionals examining how search and AI crawlers reach a site. It is strongest when teams need crawler segmentation and crawl diagnostics rather than a broader SEO suite. Its free tier is tightly capped, while paid plans offer more history and volume at a meaningful monthly cost.

Overview

The analyzer helps identify crawl budget waste, HTTP errors, orphan pages, redirect and canonical issues, and fake bots. Its dashboards follow crawl coverage, freshness, time to first visit, new URLs, and URLs crawled but never clicked. These views make it a focused diagnostic choice for understanding crawling and discovery, not a substitute for keyword or backlink analysis.

AI and LLM crawlers are tracked separately from Googlebot, with AI-versus-SEO comparisons. CrawlGenius says it checks AI crawlers against more than 3,500 official IP ranges and rejects spoofed hits during ingestion, a useful safeguard when bot identity matters to analysis.

Data is hosted in the EU and processed under GDPR; visitor IP addresses are truncated before storage. The company does not hold SOC 2 or ISO 27001 certification. CrawlGenius also excludes keyword rankings, backlink data, and outbound webhooks, so teams needing those capabilities will need other tools.

Key features

Log ingestion supports a WordPress plugin, server agent, log-file upload, Amazon S3, and FTP/sFTP deposit. FTP/sFTP is unavailable on Free. Paid plans add a REST API and MCP server for automation, while the free tier omits both. Crawler segmentation and crawl waste reports address the product’s central use case directly.

Paid plans include 13 months of history, with 90-day and three-year retention options also offered. A 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; Enterprise adds a dedicated customer success manager.

Pricing

The Free plan costs nothing and allows 10,000 log lines per month, one project, and a seven-day visible window. It is suitable for a small initial evaluation, but the low volume and short history make it a poor fit for ongoing analysis of larger sites. It also lacks FTP/sFTP, the REST API, and MCP server.

Starter costs €49 a month, billed monthly with no commitment; annual commitment reduces the price by 10%. Prices exclude VAT. It includes one project, 250,000 log lines per month, and 13 months of history; the crawler module is optional. This suits a single-site team that needs longer-term log analysis, but the project cap and optional module matter when comparing its headline price with intended use.

Agency costs €149 a month, billed monthly with no commitment, with a 10% reduction for annual commitment; prices exclude VAT. It offers unlimited projects and 500,000 log lines per month aggregated, with additional volume priced by tier. Agencies managing multiple sites benefit from the project allowance, but must watch the shared quota as client log volumes accumulate.

Enterprise has custom pricing for customers above 20 million lines per month or above 50 projects, with custom volumes and retention. The plan names no fixed price, so organizations at that scale should expect a quote rather than a published rate.

Platforms

CrawlGenius Log Analyzer is available on the web. Its integration options let teams send logs through several routes, though FTP/sFTP requires a paid plan.

Who it's for

This is best for SEO professionals who need to diagnose crawler behavior, quantify wasted crawling, or distinguish verified AI crawler activity from Googlebot. A single-site team can start with Starter if the optional crawler module and quota suit its needs; agencies get unlimited projects on Agency, but need to account for aggregated volume. It is less suitable for buyers seeking a complete SEO platform, local desktop software, or a free tier capable of substantial, long-term analysis.

Pros and cons

• Pros: Separate AI crawler tracking and comparison with Googlebot give SEO teams a focused way to examine changing crawler activity.
• Pros: The no-card, no-commitment 30-day trial works on the customer’s real logs, making evaluation more relevant than a demo dataset.
• Pros: EU hosting, GDPR processing, and truncated visitor IPs provide concrete data-handling protections.
• Cons: Free is limited to 10,000 lines monthly, one project, and seven days of visible history, restricting sustained use.
• Cons: Starter allows only one project and makes the crawler module optional, while Agency’s 500,000-line quota is aggregated across projects.
• Cons: No keyword rankings, backlink data, or outbound webhooks are included, and SOC 2 and ISO 27001 certification are absent.

Alternatives

For a broader shortlist, see SEO Log File Analysis Tools.

Choose SEO Log Auditor if an open-source MIT-licensed tool that runs locally matters more than CrawlGenius’s managed web service and AI crawler comparisons. Spider-Lens is another free, open-source self-hosted option, with no paid plans or usage limits stated.

Screaming Frog SEO Log File Analyser may suit teams that want desktop software for Linux, macOS, or Windows: its free plan covers 1,000 log event lines and one project, and its paid plan is $139 a year. Choose Log File Bot Traffic Cost Analyzer when the priority is bot-traffic cost analysis, with browser triage under 500 MB, CLI analysis from 500 MB to 50 GB, and BigQuery for 50 GB or more.

LogLens offers a free plan with 500K requests per month, one website, 30 days of history, real-time analytics, and bot and AI crawler detection; it is worth considering for readers who prefer that request-based allowance and history window. SEOMER is a web-based alternative with quick page checks and limited daily usage on its free plan. AuditLabs SEO Log File Analyzer is another web option; its maker says its tools are built by SEO practitioner Antonio Maculus, Director of AI Content Strategy at Better Collective. Crawl Lab is a free web tool with no sign-up, no paid tier, and no server-side size limit.

Verdict

Choose CrawlGenius Log Analyzer if crawler diagnostics, AI-versus-SEO segmentation, and structured log ingestion are central to your SEO work. The strongest reasons to look elsewhere are the restricted free tier, paid-plan quotas and costs, and the absence of rankings, backlink data, and outbound webhooks.
