Which "Search Term Suggestion Tools" Are Best to Use for Google?

Just wondering: Which "Search Term Suggestion Tools" Are Best to Use for Google?

So far, I am familiar with Google Adwords tool, Wordtracker, Overture & DigitalPoint keyword tool...

Please forward me names of tools (including URL where I can find tool) which will be added value to above mentioned ones!!

PS - Doesn't necessary to be a 'free' tool, also reliable good 'paid' subscription tools are fine with me!

Thanks a lot!

 

I think you pretty much covered them all there.

I tend to use overture most and divide its results by 2 to get the real traffic.

 

I think most (if not all) the tools picks up information from these 3 places only.

 

You mentioned: "I tend to use overture most and divide its results by 2 to get the real traffic."

Sorry, didn't understand what you mean by divide its results by 2 to get the real traffic? How do you divide? Can you explain again?

Thanks a lot!

 

If overture estimates 10,000 searches per month then there are likely to be about 5,000 searches per month.

No idea why this is or if its true. Its just my experience in certain markets.

 

As far as I knew Overture doesn't "PREDICT" anything. It displays the number of searches for that term from the PREVIOUS month.
The DP Tool (a good one) combines both Overture and Wordtracker into one.
