I get 9 to 10 visitors on a 1900 exact search keyword I am #1 for. I have been #1 for a while but I should be getting over 60 users on average. I hate Google.wned:
I guess you should always under estimate when doing research.
You have over estimated your potential for this keyword by assuming that pos 1 gets 100% of the exact. You also assume that you are in pos 1 for 100% of the google local figure (ie everywhere that the local figure applies to). Both are not necessarily correct (the first is guaranteed not to be).
For exact match, take the local exact and multiply it by a 3rd for pos 1 traffic. Now halve it. It is a reasonable guide to reality and holds up in anything I have looked at so far.
In your situation ... 1900/30 = 63. 63*.3 = 21. 21*.5 = 10 to 11 per day.
