I am looking for a tool where i can research about long tail keywords. I have used many seo tools. but I am not which is the best for finding long tail keywords. please help.
There are a few of such tools. You could try HitTail, Long Tail AdWords.com or simply fiddle around with Google AdWords Keyword Tool.
As usual, thanks for the mention. HitTail analyzes the traffic ON YOUR OWN SITE. This is best for either natural search optimization (catapulting under-performing terms to the first page of Google by adding new optimized content) or PPC optimization (by adding low-cost, highly qualified and trafficked keywords to your campaigns).
another free tool that I've found very good for generating long tails is one called Massive Keyword List Builder from ibizresearch.com
I have been using HitTail for a while now. Even bought the Plus package for some of my premium sites. All I can say that it has paid for itself many times over. I still use the free version for minor sites and the info is excellent as well. Well worth trying the free option - what do you have to lose?
That's what I'm going to post here... My favorite is hittail.. It gives me searches of long-tail keywords of the visitors on SE...
The problem is finding a tool that is accurate (hittail excluded as it uses your own log files). I have yet to find one that is reliable. I have not been impressed with wordze so the search continues.
Just use any keyword adviser and then in the front of them add "free" or "cheap" or something like that lol just kidding
