CrawlGenius Log Analyzer

CrawlGenius Log Analyzer is a web service for examining how search engines and AI crawlers move through server logs. It is best suited to SEO professionals and teams responsible for large or technically complex websites. The product is a focused crawler-diagnostics platform, but its free limits and excluded SEO data make careful plan selection essential.

Overview

The analyzer turns raw requests into reports on crawl-budget waste, HTTP errors, orphan pages, redirect and canonical problems, and fake bots. Dashboards cover crawl coverage, freshness, time to first visit, newly discovered URLs, and URLs crawled without a click. Those views are practical for finding inefficient discovery and prioritising technical SEO work, rather than for measuring rankings or link authority.

AI and LLM crawlers are separated from Googlebot, with comparisons between AI and conventional SEO activity. CrawlGenius says claimed AI crawlers are checked against more than 3,500 official IP ranges and that spoofed hits are rejected during ingestion. That verification makes the AI-versus-SEO reporting more useful than a simple user-agent count.

The service is hosted in the EU, processes data under GDPR, and truncates visitor IP addresses before storage. It does not currently hold SOC 2 or ISO 27001 certification. Keyword rankings, backlink data, and outbound webhooks are outside the product's scope, so it should not be treated as a complete SEO suite or an automation endpoint for every workflow.

Key features

Log collection can use a WordPress plugin, server agent, uploaded log files, Amazon S3, or an FTP/sFTP deposit. FTP/sFTP is excluded from the Free plan. Crawler segmentation and crawl-waste reports are core capabilities, while paid subscriptions add a REST API and MCP server for programmatic access; Free provides neither.

The guided trial analyses a customer's real logs for 30 days without a credit card or commitment. Founder-led onboarding, training, and technical SEO advice are part of the support model, and Enterprise adds a dedicated customer success manager. Paid plans include 13 months of history, with 90-day and three-year retention options also offered, allowing organisations to match storage cost to reporting needs.

Pricing

CrawlGenius uses a freemium model, with paid access advertised from €44.10 per month and a 30-day trial. Prices below exclude VAT unless stated otherwise.

• Free — free: 10,000 log lines per month, one project, and a seven-day visible window. It is suitable for a small site or an initial evaluation, but the short window, single project, low quota, lack of FTP/sFTP, and absence of API or MCP access quickly constrain recurring analysis.
• Starter — €49 a month: billed monthly with no commitment, or 10% less with an annual commitment. It includes one project, 250,000 log lines per month, and 13 months of history; the crawler module is optional. This is the sensible fit for one substantial website that needs longitudinal reporting, though the project cap and optional crawler component matter.
• Agency — €149 a month: billed monthly with no commitment, or 10% less annually. Unlimited projects share an aggregate 500,000-line monthly allowance, with additional volume priced by tier. Agencies gain room for multiple clients, but high-traffic portfolios may incur extra charges.
• Enterprise — custom pricing: billed by custom quote for more than 20 million lines per month or more than 50 projects, with custom volumes and retention. It is aimed at organisations whose ingestion and storage requirements exceed the fixed plans.

All paid plans are substantially more capable than Free, but the quotas are measured in log lines rather than sites alone. Teams should estimate monthly traffic before choosing a tier, especially when several projects share an Agency allowance.

Platforms

CrawlGenius is delivered through the web. Its ingestion connectors extend into WordPress, servers, uploaded files, Amazon S3, and FTP/sFTP, but the latter requires a paid plan.

Who it's for

SEO professionals diagnosing crawl efficiency, bot authenticity, and technical discovery patterns are the natural audience. Starter fits a single serious site; Agency is for teams managing multiple properties; Enterprise is for very high-volume estates or more than 50 projects. Free makes sense for a small site, a short audit, or a trial of the reporting model, not as a long-term archive.

Pros and cons

Pros

• Separate AI crawler analysis: AI/LLM activity is compared directly with Googlebot activity, and IP-range verification filters spoofed requests.
• Actionable crawl diagnostics: Waste, errors, orphan URLs, redirects, canonicals, freshness, and unclicked URLs are covered in one focused workspace.
• European privacy posture: EU hosting, GDPR processing, and truncated visitor IPs reduce exposure for privacy-conscious organisations.
• Useful paid ingestion and automation: S3, FTP/sFTP, REST API, and MCP support more operational workflows than the Free tier.

Cons

• Restrictive Free tier: 10,000 lines monthly, one project, and only seven visible days limit ongoing monitoring.
• Meaningful recurring cost: Starter is €49 monthly and Agency €149 monthly before VAT, with extra Agency volume charged by tier.
• Narrow SEO scope: No keyword rankings, backlink data, or outbound webhooks are included.
• No major security certifications: SOC 2 and ISO 27001 are not currently held.

Alternatives

SEO Log File Analysis Tools is the broader starting point for comparing products in this category.

Choose SEO Log Auditor instead if you want free, open-source software that runs locally across Linux, macOS, Windows, and the web, with no paid tier.

Spider-Lens is a free, open-source self-hosted option with no stated usage limits and broad platform support.

Pick Screaming Frog SEO Log File Analyser for desktop Linux, macOS, or Windows use; its Free plan handles 1,000 log event lines and its paid licence costs $139 a year.

LogLens suits users seeking API or self-hosted deployment, real-time analytics, and bot and AI crawler detection on a freemium model.

SEOMER is a web alternative centred on quick page checks and usage top-ups rather than dedicated server-log operations.

Log File Bot Traffic Cost Analyzer is preferable for local or BigQuery-based bot-traffic cost work, from browser triage to very large files.

AuditLabs SEO Log File Analyzer is another web freemium choice, built by SEO practitioner Antonio Maculus.

Crawl Lab is a free web tool with no sign-up, no paid tier, and no server-side size limit.

Verdict

CrawlGenius Log Analyzer is a strong choice for SEO teams that specifically need trustworthy crawler segmentation, AI-bot visibility, and detailed crawl-waste diagnosis from server logs. Choose it when EU-hosted analysis, long history, and paid ingestion or automation justify the subscription. Look elsewhere if you need rankings, backlinks, webhooks, desktop or self-hosted operation, or a generous free tier for sustained high-volume use.
