Drop in a server log file and see which pages search engines and AI crawlers really request, how often, and where they hit errors or waste time.
Server logs are the only record of what crawlers actually do on your website. The Visiblio Log Analyser reads an access log in your browser, recognises Googlebot, Bingbot and AI crawlers such as GPTBot, and shows which pages they visit, how often and what status codes they get back.
Your file is processed on your own computer, and large files are read in pieces so they do not have to fit in memory.
See what bots request, not what a sitemap says they should.
Check whether AI assistants' crawlers are visiting your content.
Find error pages, redirects and low-value URLs eating crawler time.
The file is not uploaded to Visiblio's servers.
Load the sample to see the report before using your own file.
A summary of visits by crawler, with the day-by-day pattern, so you can see when and how heavily search engines crawl.
A table of the most requested URLs with their status codes and folders, so you can spot parameters, duplicates and error pages.
See which URLs return 404 or 5xx errors to crawlers and how often, to prioritise fixes.
Ask your host or developer for an access log, or download it from your server.
Select the file. It is read in your browser and nothing is uploaded.
Review crawler activity, crawled pages and errors, then fix what wastes crawling.
Prove what crawlers do instead of assuming.
Find crawl waste on sites with many URLs.
See whether AI crawlers fetch your key pages.

A log file analyser reads your web server's access log and shows which URLs were requested, by whom and with what result. For SEO, it shows exactly how search engine crawlers behave on your site.
Logs show real crawler visits, including pages that are crawled too often, pages never crawled, and errors returned to bots. This is information that crawling your own site or reading Search Console cannot fully give.
No. The file is read in your browser, and the analysis happens on your computer.
Common access log formats from web servers and CDNs are supported. If a format is not read correctly, start with the sample file to see what is expected.
You can start for free. Plans set the size of the file and the number of analyses each month.
Open the tool, add your website or a page address and see the result in minutes. It is free to start.
