Do you think this keyword tool just an example : http://tools.seobook.com/general/keyword/ does show accurate searches done by them, because i am getting ranked top three for an keyword which is searched for 3,674 in google for a month, but i did not get any single search from that keyword, but I get visitors for different keyword where it shows less but more visitors for that, how come this
I like to try different keyword tools. Some list terms in wrong order and you do not get good results. Check your keywords in other tools and see how much traffic the term gets.
