如何检测googlebot并找出已抓取的网页以及googlebot已完成的所有其他内容？

Question

I want to gather all data and use it for own purposes from my CRM.

Answer 1

if (preg_match("~google~is", $_SERVER['HTTP_USER_AGENT'])) {
    echo "Find GoogleBot!";
}

You can use $_SERVER['HTTP_USER_AGENT'] to check for keywords, "google" will be enough probably.
