Google Keyword Tool vs Wordtracker
question about differences in the two

Can anyone give me a simple explanation for why the numbers in Google's keyword tool are so completely different than Wordtracker's search numbers?

I've always used Wordtracker, and now have a client questioning the accuracy of it.

Wordtracker shows the number of searches for one term 450 per month. Google's tool show it at 14,800...which seems utterly ridiculous to me. I think Wordtracker has to be the correct one.

Google shows the highest term for that type of business is "another term". (90,000!) That doesn't even register as a search term on Wordtracker! What do ya'll think this is about?

If you click on the question mark icon at the top of the Local Search Volume and Global Monthly Search Volume you will see this:

"This statistic applies to searches on Google and the search network"

In other words, the figures you see include Adwords traffic from all sources in their search network, not just Google itself.

In short, it's not a good indicator of how much traffic you can expect from Google from SEO.

Hi there,

my name's Mal Darwen, and I work for Wordtracker Customer Services. I hope the following is of some use to you:

Google's Adwords tool can be a useful addition to the SEO's toolkit, although it does seem to be more geared towards the PPC market. However, the number of results returned by Google is 200 while with Wordtracker, users get and can download up to 1000 keywords.

We feel that Google is using this new tool to generate new Adwords accounts
from where it makes its money. Wordtracker provides an independent keyword
research service on a subscription basis – we do not make money from each
keyword result that people might build on.

While Google reports impressive search volumes, there are a number of
• The figures Google provides are not actual searches but approximations. Like WT, Google takes a small sample and extrapolates an estimate from that. From our research that sample appears small but we’re still investigating.
• The default search position is ‘broad match’. This highly inflates the search estimates for a particular keyword.

Here is Google’s definition:

Broad Match - This is the default option. If you include general keyword or keyword phrases (such as tennis shoes) in your keyword list, your ads may appear when users search for tennis and shoes, in any order, and possibly along with other terms. For example, your ad may appear for the queries buy tennis shoes and tennis sneakers but not tennis players. Your ads may also be displayed on relevant variations of your keyword phrases and plurals, as
well as some related keywords and phrases via our expanded keyword matching technology.

Broad matches are often less targeted than exact or phrase matches.

• The estimates returned by Google also contain searches from Google’s content network. That’s the wide range of sites that publish Google ads.
• Google are also reporting monthly estimates while Wordtracker provides daily estimates.
This means that on first examination the Google counts will seem much higher than WT.

Wordtracker has always been completely open about where we get our data from. We take our information from two metacrawlers, Dogpile.com and Metacrawler.com. People use such search engines to search Google, MSN and Yahoo at the same time and as such provides very clean bot-free data. We get daily records which represents approximately just under 1% of daily searches across all search engines.

As I say, I hope this makes things a little clearer.

Mal and others,
I truly appreciate you taking the time to tell me this. I will keep it to use as a reply many times over. It is exactly what I suggested to the client (actually her webmaster) but to see it in print is a great help. Thank you so much, all!
