Basically what im after is a tool that can accurately analyze keyword competition for a certain term... Say - free flash games I wanna know how many links the 100th site in google has to achieve a rank of 100 for this particular search time. Are there tools that accurately do this?
I don't know if I understood you correctly, but is this what you were looking for ? http://inventory.overture.com/d/searchinventory/suggestion/
Ya Ive used that tool pretty good too, although it gives the results for first 10 , rather than say 90-100. Would be cool if that was an option. Also the accuracy is a little astray for some things, like "Number of times searched last month". Ive seen it say 0, when it was at least 10,000 times..but overall its a very useful tool, especially for keeping an eye on the top 10.
If you don't mind then you could check my tool which will give you top 20 competitors pages technical info which you need. IMHO it doesn't matter whether you are on 100 position or 21 because after 15 or 20 rank you will not get traffic. It is free.
