![]() ![]() ![]() ![]() This is to avoid multiple requests at a time. Rate limiting ( effective in blocking constant post request ESPECIALLY for forms without captcha ) : This is for bots that will RESPECT robots.txt ( like search engines googlebot|msnbot|slurp.).ģ.

That would be the ideal way to cloak for spiders. ![]() ( I am not sure how but this is for sure the best way to track them ) One distinctive feature of most of the bot is that they don't carry any cookie and so no session is attached to them.

In this code we check "hostname" which should contain "" or "" at the end of "hostname" which is really important to check exact domain not subdomain. Verify that it is the same as the original accessing IP address from your logs. If you really need to detect GOOGLE engine bots you should never rely on "user_agent" or "IP" address because "user_agent" can be changed and acording to what google said in: Verifying Googlebotġ.Run a reverse DNS lookup on the accessing IP address from your logs, using the host command.Ģ.Verify that the domain name is in either or ģ.Run a forward DNS lookup on the domain name retrieved in step 1 using the host command on the retrieved domain name. I've written a library in Java that performs these checks for you. If the resulting IP is the same as the one of the site's visitor, you're sure it's a crawler from that search engine. Then, because someone could set such a reverse DNS on his IP, you need to verify with a forward DNS lookup on that hostname. For Google this brings a host name under, for Bing it's under. The top search engines officially support verification through DNS, as explained by Google and Bing Īt first perform a reverse DNS lookup of the client IP. All the lists you find online are outdated. In the old days this required maintaining IP lists. The 2nd part is verifying the client's IP. If (strpos($crawlers_agents, $USER_AGENT) = false)īecause any client can set the user-agent to what they want, looking for 'Googlebot', 'bingbot' etc is only half the job. $crawlers_agents = implode('|',$crawlers) it is better to save it in string than use implode every time to get crawlers string used in function uncomment it You can checkout if it's a search engine with this function : 'Google', ![]()
