Keyword Tools: Google vs. Wordtracker
by Rosalind Gardner
June 22, 2009

First of all, what you?ll notice when you do keyword searches using Google?s Keyword Tool and Wordtracker, is that you see wildly different numbers... what we first have to realize is that Google is reporting monthly figures and Wordtracker is reporting daily figures. More importantly, the default search on Google returns Broad match results whereas Wordtracker returns an Exact match.

Why the big difference?
Wordtracker is open about the fact that they extract and extrapolate their data from two metacrawlers, Dogpile.com and Metacrawler.com - services that query all the main search engines simultaneously. Their results represent approximately just under 1% of daily searches across all search engines. However, only Google knows the size of the sample that they use to extrapolate their information, although it is known that Content Network search results are included.

Too, you must consider the fact that Google has a vested interest in making their numbers appear large - as primary users of the Google Keyword Tool are either current or potential Adwords customers. Wordtracker, on the other hand, has no reason to inflate numbers. They simply provide a keyword research service.
