One small problem is you can only to see fetch as googlebot in the google webmaster tool, so you can’t see other sites’ situation. and today I’ll introduce you a new way to act as googlebot: User-Agent

How to edit the User Agent string

To change the User Agent string, just enter

about:config

as an address in the address bar of FireFox, the location where you normally enter a URL (link). I recommend to preserve the original value, which you can get when you enter just about: in the address bar.

Remember to keep the original value, the googltbot sight can’t view the flash and other script code.

Now press the right mouse button to get the context menu and select “String” from the menu entry “New”. Enter the preference name “general.useragent.override”

without the quotes. Next, enter the new User Agent value you want Mozilla Firefox to use. I added my name and a link to my web site to the original value. You can also pick one from the list of User Agent strings. Check the new value by entering about: in the address bar.

Detecting Googlebot cloaking

The User Agent string “Googlebot/2.1 (+http://www.googlebot.com/bot.html)“, without the quotes can sometimes be used to discover sites that use a simple technique to feed Google’s spider (“Googlebot”) optimized web pages in order to obtain a higher position (spamdexing). This technique is a form of cloaking that is in most cases against the terms of services of Google. If you discover such a web site, and the page can be found with Google, report the offending site to Google for a better search experience.
