help Seolyzer FAQ

What does Seolyzer analyze?

Seolyzer is primarily a log-analysis tool for SEO teams, using server log files to show how search-engine crawlers move through a site. It can reveal crawl activity, response codes, and pages that receive little or no crawler attention.

Does Seolyzer replace Google PageSpeed Insights?

No. Google PageSpeed Insights measures page performance and user-experience signals, while Seolyzer studies server logs and crawler behavior. They answer different questions and can be used together.

Which search engines can Seolyzer help monitor?

Its main SEO use is analyzing crawler visits such as Googlebot and Bingbot recorded in server logs. The exact bot identification depends on the log data and the tool’s current processing rules.

Why would an SEO specialist use Seolyzer?

It can expose crawl-budget waste, repeated visits to unimportant URLs, and technical errors that ordinary analytics may miss. That information helps prioritize internal-linking, status-code, and indexing fixes.
