I'm currently using google keyword tool and IBP for the keyword analysis. But the thing is both tool are stating different numbers, for example:

As Per Google Keyword Tool:

Global Monthly Searches for the keyword iPhone to PC Transfer: 301,000 and Local Monthly Searches (US): 110,000

And as per IBP Keyword Tool Local Monthly Searches for the above keyword is less than 10

So I'm little confused by these stats. Can anybody tell me which one is correct? And the above keyword is worth to traget or not?
