Googlebot Validation

Google has finally completed a DNS project that will allow us to use a simple reverse and forward DNS check to verify it's really, truly, honestly Googlebot and not a cheap immitation, or Google crawling thru a proxy, or anything else you can imagine.

I'm so sick of explaining why you might need this and what it solves you'll just have to follow a few links and read the threads at these various places.

Here's the official How To Verify Googlebot post on Google's blog.

Then you can check out what's been said about How To Verify Googlebot on Matt's blog.

Then a couple of threads on WMW about Verifying Googlebot that should answer any other questions on this topic.

Thanks again to Matt for getting this project finished!
