How do you prevent the mobile site becoming a duplicate of the full browser site?

[pulseseo]

We have a larger site with 100k+ pages, we need to create a mobile site which gets indexed in the mobile engines but I am afraid that google bot will consider these pages duplicates of the normal site pages.

I know I can block it on the robots.txt but I still need it to be indexed for mobile search engines and I think google has a mobile crawler as well.

Feel free to give me any other tips that I should follow while trying to optimize the mobile version.

Any help would be appreciated

Hi Manoj,

You shouldn't have a problem if you do it right. Google has separate bots,  GoogleBot and GoogleBot Mobile. I can explain how it works but Matt already did it much better. Link to video is attached for you.
