According to google keyword tool the search is 65000 per month (global) but I am getting a few visitors just 20-15! It is on the first position in google!
65000 is search metric not click metric. we all know that adwords tool is not accurate but its shows approx results let us know more about your keyword
Just because impressions are high Definitely does not guarantee lots of clicks just because you are the top ad for your keyword. You must create interesting ad text and also try your best to climb the rankings on organic indexes. By creating better ads then your competitors you will see your click through ratio increase.
Its not meant to be accurate, its to give you an idea of whats being searched. Also use local, as Global is an estimation for the year, which as we all know trends come and go fast...
you have to check "local searches" for "Exact match" not global for broad as that makes a big difference.
the 65k searches is global, are you listed as number 1 for all local google versions too? for e.g. google.com, google.co.uk, google.de etc? if its that link in your sig i dont see it on first page on google uk search
It seems Google AdWords is more about providing estimates because more often than not, even when you're doing keyword research they start trying to come up with all sorts of variants that you didn't want.
