i want to know that how manytimes a spcific keyword is serch daily on google?

 

You can always use the Google Keywords tool to find that information: https://adwords.google.com/select/KeywordToolExternal

 

using the external adwords keyword tool it will give you a monthly average,
to find out a daily average for yahoo, google or msn individually you can go to
seobook.com and select the tools tab and use the free keyword tool that they
have available.

 

Thanks its very helpful 4 me.
