Person-agent strings are important for controlling which AI crawlers can entry your web site, however official documentation is commonly outdated, incomplete, or lacking solely. So, we curated a verified checklist of AI crawlers from our precise server logs as a helpful reference.
Each user-agent is validated towards official IP lists when obtainable, making certain accuracy. We’ll keep and replace this checklist to catch new crawlers and adjustments to present ones.

Fashionable AI Agent Crawlers With Unidentifiable Person Agent
We’ve discovered that the next didn’t determine themselves:
- you.com.
- ChatGPT’s agent Operator.
- Bing’s Copilot chat.
- Grok.
- DeepSeek.
There is no such thing as a approach to monitor this crawler from accessing webpages apart from by figuring out the express IP.
We arrange a lure web page (e.g., /specific-page-for-you-com/) and used the on-page chat to immediate you.com to go to it, permitting us to find the corresponding go to document and IP handle in our server logs. Under is the screenshot:
What About Agentic AI Browsers?
Sadly, AI browsers resembling Comet or ChatGPT’s Atlas don’t differentiate themselves within the person agent string, and you may’t determine them in server logs and mix with regular customers’ visits.

That is disappointing for SEOs as a result of monitoring agentic browser visits to a web site is vital for reporting POV.
How To Examine What’s Crawling Your Server
Some internet hosting corporations provide a person interface (UI) that makes it simple to entry and take a look at server logs, relying on what internet hosting service you’re utilizing.
In case your internet hosting doesn’t provide this, you may get server log information (often situated /var/log/apache2/entry.log in Linux-based servers) through FTP or request it out of your server help to ship it to you.
After getting the log file, you possibly can view and analyze it in both Google Sheets (if the file is in CSV format), Screaming Frog’s log analyzer, or, in case your log file is lower than 100 MB, you possibly can attempt analyzing it with Gemini AI.
How To Confirm Legit Vs. Pretend Bots
Pretend crawlers can spoof respectable person brokers to bypass restrictions and scrape content material aggressively. For instance, anybody can impersonate ClaudeBot from their laptop computer and provoke crawl request from the terminal. In your server log, you will note it as Claudebot is crawling it:
curl -A 'Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; suitable; ClaudeBot/1.0; +claudebot@anthropic.com)' https://instance.com
Verification might help to save lots of server bandwidth and forestall harvesting content material illegally. Probably the most dependable verification methodology you possibly can apply is checking the request IP.
Examine all IPs and scan to match if it’s one of many formally declared IPs listed above. In that case, you possibly can permit the request; in any other case, block.
Numerous forms of firewalls might help you with this through allowlist verified IPs (which permits respectable bot requests to go by), and all different requests impersonating AI crawlers of their person agent strings are blocked.
For instance, in WordPress, you need to use Wordfence free plugin to allowlist respectable IPs from the official lists (as above) and add blocking customized guidelines as beneath:
The allowlist rule is superior, and it’ll let respectable crawlers go by and block any impersonation request which comes from totally different IPs.
Nevertheless, please word that it’s doable to spoof an IP handle, and in that case, when bot person agent and IPs are spoofed, you received’t have the ability to block it.
