The infrastructure of OnCrawl Log Analyzer lets you upload log entries every day at scale and analyze millions of search engines hits per day.

OnCrawl is the first and only one to calculate how long it takes to a page to be crawled for the first time by Google and how long it takes to generate its first SEO visit.

Live log monitoring helps you anticipate changes and monitor site events hour-by-hour or even minute-by-minute.

We automatically process Apache, IIS, and Nginx log files but we are always working on custom parsers to support other formats.

Our customers use OnCrawl to skyrocket their SEO performance

Providing deeper and more reliable SEO audits

I have been able to find certain issues that I generally would not have found using other tools. The search engine ranking drop, after the website was redesigned, occurred around April 2017. Since doing the SEO audit of the NBRI website, using OnCrawl data, the website is now ranking for about 1,000 more keywords across the board.
