SEO & marketing crawler that measures crawl, content, and links
OnCrawl is a technical SEO platform that combines large-scale website crawling with log analysis and data-driven correlation to prioritize SEO work for agencies and in-house teams. It’s best for SEO managers, technical SEOs, and digital agencies who need crawl-driven diagnostics and data modeling; pricing ranges from entry paid plans to custom enterprise contracts, so it’s a commercial, scalable tool rather than a free alternative.
OnCrawl is an enterprise-focused SEO & marketing platform that crawls sites, analyzes logs, and correlates crawl data with rankings to surface technical SEO priorities. It specializes in combining crawl maps, page-level metrics, and server log analysis so teams can attribute indexation and traffic trends to on-site issues. The platform’s key differentiator is its data-model approach that links crawlability, content, and internal linking with Googlebot activity. OnCrawl serves technical SEOs, in-house marketing teams, and agencies; pricing is commercial with tiered paid plans and custom enterprise options.
OnCrawl is a technical SEO platform founded to help SEO teams translate crawling data and server logs into prioritised actions. Originating in France and built for enterprise-scale websites, OnCrawl positions itself at the intersection of SEO crawling, log analytics, and data science. Its core value proposition is to move beyond one-off site crawls by producing time-series datasets and correlations that explain whether indexing and organic performance changes are caused by crawlability, content issues, or site architecture. The product emphasizes measurable SEO outcomes across large domains and complex site architectures.
The product provides several concrete features. First, OnCrawl’s web crawler can process millions of URLs with configurable crawl settings, rendering JavaScript when needed and exporting crawl maps and URL-level metrics. Second, the Log Analyzer ingests web server logs (gzip, raw or streaming) to map Googlebot and other crawler activity against the site structure; it surfaces which URLs are crawled, crawl frequency, and 404/500 responses over time. Third, the Data Studio and correlation reports join crawl data, log data, and Google Search Console or Google Analytics to compute correlations between technical metrics (crawl depth, internal links) and organic traffic or impressions. Fourth, OnCrawl’s API and CSV exports let teams import data into BI tools or run custom analyses, and built-in visualizations include crawl maps, indexation funnels, and link equity charts.
OnCrawl’s pricing is tiered and aimed at professional buyers. There is no unlimited free plan; instead the company offers trial/demo options and entry paid plans with URL or crawl-unit limits. As of the latest published pricing, OnCrawl sells Starter/Pro-like tiers with monthly URL or crawl-credit limits and Core plans starting in the low hundreds of euros/dollars per month for smaller sites, while larger Business and Enterprise tiers move to custom pricing with higher limits, SLAs, and SSO. Paid tiers unlock larger monthly URL allowances, Log Analyzer credits, historical trend retention, and API access; enterprise plans add custom ingestion, dedicated onboarding, and priority support. Exact live prices should be confirmed on OnCrawl’s pricing page or with sales.
OnCrawl is used by technical SEOs, in-house search teams, and agencies that manage large catalogs or international sites. For example, a Technical SEO Manager uses OnCrawl to reduce indexation gaps by 30% through combined crawl-log correlation and prioritized fixes, and an SEO Director at an ecommerce retailer uses the Log Analyzer to identify crawler budget waste and improve crawl frequency on high-value product pages. It also fits content ops teams who need page-level visibility on internal linking and duplicate content. If you need a simpler dashboard or lower-cost keyword tracking only, consider alternatives like Screaming Frog for small audits or Botify for similarly enterprise crawl+log analysis features.
