Okay, so with most of my niche websites, Keyword Tracker has been very useful and accurate. However, with a term that I think is solidly searched a few times per day, Keyword Tracker has it at around 4,000 while the other keyword research tools have it at 900, 310, and 19 respectively. All of these tools claim to have the best stats from all the major search engines....but I dont know what to think of a 19-4000 range...any suggestions?
Usually in these kinds of situations I would say work out the average however thats a large range. Could I firstly ask which keyword research tools you found these results on?
