AI Crawler Log Analyzer

Paste raw lines from your server access log. You get the number of lines parsed, how many hits came from AI crawlers and what share of traffic that is, plus a per-bot breakdown with owner, hit count and the status codes each one received. Nothing is stored.

How do I check if AI crawlers visit my site?

Your server access log records every request, including AI crawlers, and it is the only place you can see them. Google Search Console only reports Google's own crawlers. Download or copy your access log, paste the lines into a log analyzer, and it will match user-agent strings like GPTBot, PerplexityBot and Claude-SearchBot and count their visits.

Why logs

Robots.txt says allowed. Logs say what happened.

Checking robots.txt tells you what you have permitted. It does not tell you whether anything turned up. A site can allow every AI crawler and still get no visits, usually because nothing links to it or the pages are too thin to be worth fetching. The log is the only honest record. Every request your server answers gets written down, with the time, the page and the user-agent that asked.

Search Console will not show you this

The Crawl Stats report in Google Search Console covers Google's own crawlers only. It does not report GPTBot, PerplexityBot, ClaudeBot or anything else from OpenAI, Anthropic or Perplexity. If you want to know whether those bots reached you, the access log is the source.

Status codes tell the real story

A bot that visited and got a 200 read your page. A bot that got 403 was refused, usually by a firewall or bot-protection rule rather than robots.txt. A bot that got 404 followed a broken link. We show the codes each crawler received so you can tell those cases apart.

Where to find your access log

Pick the line that matches your setup, then copy a few hundred lines.

Reading the output

What the numbers mean for a local business

Do not chase a big AI crawler percentage. A high share can simply mean human traffic is low. Read the three numbers together: how many lines you pasted, how many were AI crawlers, and which bots those were. A handful of hits from OAI-SearchBot and PerplexityBot is a better sign than hundreds of hits from one training crawler.

Zero AI hits

This is common and it is not always a problem. It can mean your robots.txt blocks them, that your firewall is refusing them, or simply that the sample you pasted is too short. Try a longer stretch of log first, then run the crawler access checker.

Training bots but no search bots

If you see GPTBot and ClaudeBot but nothing from OAI-SearchBot, Claude-SearchBot or PerplexityBot, your content is being read for training but not being fetched for answers. That usually points to weak external links and few mentions rather than a technical block.

One bot doing all the work

Sometimes a single crawler accounts for almost every AI hit. That is normal, and it tells you which engine is most likely to know your site today. It also tells you where a block would hurt most, because losing that one bot would take out most of your AI visibility.

Privacy and limits

What we do not do with your log

Nothing you paste is stored. The lines are parsed to produce the counts and then they are gone. Two honest limits: we only read standard combined-format access logs, so a custom log format may not parse, and we can only match bots by their user-agent string. A scraper can claim to be anything, so treat the breakdown as a strong signal rather than proof of identity. Google-Extended and Applebot-Extended will never appear at all, because they do not crawl.

Next steps

What to do with what you find

The log tells you what is happening. It does not tell you why. Pair it with a robots.txt check so you can separate a permission problem from a demand problem, and re-run it monthly so you have a trend rather than a snapshot.

If crawlers are being refused

Repeated 403 responses to named AI bots point at your firewall, CDN or a security plugin, not robots.txt. On Cloudflare, check your bot-fighting and WAF rules. On managed hosting, ask support whether AI user agents are filtered by default, because some are blocked out of the box.

If crawlers get in but you are not cited

Access was never the whole job. Being fetched and being quoted are different things. Once the log shows healthy crawler visits, the work moves to content: answering real questions plainly, being mentioned on other sites, and keeping your business details consistent everywhere.

Questions

AI Crawler Log Analyzer FAQ

Where do I find my server access log?

On Hostinger, open hPanel, go to Files and then Access Logs. On cPanel hosting, look under Metrics for Raw Access, or open File Manager and check the logs folder. On a server you manage, the file is usually at /var/log/nginx/access.log or /var/log/apache2/access.log. If you cannot find it, your host's support team can send it to you.

Is it safe to paste my log file here?

We do not store anything you paste. The lines are parsed in the request that produces your results and are not saved. That said, access logs contain visitor IP addresses, so use your own judgment. If you would rather not paste real data, you can remove the first column from each line before pasting and the bot matching still works.

How many log lines should I paste?

Enough to cover at least a few days. AI crawlers visit small sites irregularly, so a single hour can easily show zero hits and tell you nothing. A few hundred to a few thousand lines usually gives a fair picture. If your log is enormous, take a recent continuous block rather than lines picked from different weeks.

What log format does this accept?

Standard combined format, which is the default on Apache and Nginx and what almost all shared hosts produce. Each line carries the IP, the timestamp in brackets, the request in quotes, the status code, the bytes sent, the referrer and the user-agent. If your lines look different because someone customized the format, the parser may skip them.

Can a bot pretend to be GPTBot?

Yes. A user-agent string is just text the requester sends, so anything can claim to be any bot. Verifying a crawler properly means checking the requesting IP address against the ranges each company publishes. This tool matches on the user-agent name only, which is reliable enough for a health check but is not proof of identity.
