Seolyzer is a hybrid SEO tool that combines site crawl diagnostics with server log analytics—offering a detailed look into how search engines interact with your site. It pinpoints crawl budget inefficiencies by identifying URLs that search engines request often, pages that trigger errors, or blocked file types that could harm indexation.

Alongside crawl log monitoring, Seolyzer provides technical SEO auditing: identifying missing titles, oversized pages, slow load times, or misconfigured headers.
