Wordtracker or Google Adwords Tool:Which one to trust?

Well, from my experience, I can say both are rough estimates but I will have to go with Google since we all use Google as our Search engine. However, do note that it also doesn't return very accurate results...

With regards to Wordtracker, the difference in searches is because the source of Wordtracker data is complied from DogPile and MetaCrawler.

That explains the difference between the 2 keyword tool.

However, wordtracker can be very useful in getting some quick related keyword phrases. and if you are doing niche research, I would suggest you compile the data from both search engine and also read up on your market Forums, Yahoo Ans, Magazines etc.

google adwords keyword tool used more because it is free.
And wordstracker is free and paid both so it is used less .

personally i prefer Wordtracker as it is more correct as compare to Google Adword which only provide with us limited data

In my experience, Google's figures are often a wild guess. But it's better than nothing and gives a place to start.

Wordtracker's sample is too limited for me - when was the last time anyone you know used Dogpile?

Whilst there's no specific numbers data, Google Insights for Search and also the suggestions that appear as you type in your search are great places to find untapped keywords with decent volume. Insights because it shows the trends, the suggestions because a lot of people will choose them rather than keep typing.
