Keywords Research and their Importance!

Are the keyword results shown up by Google by search volumes is the correct data and how much one can rely on this data??

I’ve been told that they deliberately misrepresent that data but there’s no logic to that that, since they didn’t need to supply it in the first place, nor is there any proof to support it.

The numbers for sure though are skewed by people doing, marketing, SEO or PPC research type searches and so should only ever be taken as a rough guide to how popular or competitive a keyword phrase might be.

Yes, is right i think …
In Google Adword, you can know volume search about all keyword that you want …
But, most important is choice a relevant keyword with your’e sites …

Thanks
