Test Driving The AdWords Keyword Tool

September 7th, 2008 by Adam

On the first week of July 2008, the Internet Marketing community received great news: the Keyword Tool in Google’s AdWords started to show real numbers for search volumes instead of shaded bars.

My Inbox was flooded with messages from all the newsletters I subscribe to, announcing the revolution. One of the marketing gurus went so far as to conclude: “it probably spells the end for services like Wordtracker.” Another guru couldn’t curb his enthusiasm: “Holy cow! Talk about shaking up the planet!”

Jim Morris, a keyword research authority, posted the following on his nichbot.com blog: “All of a sudden - there is no longer any confusion about how many times people are searching for a certain keyword phrase on Google.com.”

Mr. Morris included in his post a screenshot of 8 results the Tool returned when he had asked for keyword suggestions for the term “blogging.” Here they are: blogging, blogs, blog, blogging software, radio blog, pink is the new blog, blog search, bad girls blog. Three columns follow the keywords list: Advertiser Competition, Approx Search Volume for last month, and Approx Average Search Volume.

Prior to July 2008, these 3 columns showed a shaded green bar, which somehow represented the volumes, i.e. if the bar was fully shaded it must have indicated very high volume; an empty bar indicated no competition etc. Now, the columns of search volume include actual numbers, while the Advertiser Competition column still shows shaded bars.

I went through the suggestions Jim Morris got for “blogging” and checked a couple of them. For instance, the Advertiser Competition bar next to “radio blog” is painted 3/4 green. Looks like quite a lot of bidders on this keyword, doesn’t it? One expects to find a lot of ads when “radio blog” is searched. Well, not necessarily. There is not even one ad for “radio blog” (at least there were none on 7/8/2008, when the blog was published and I conducted my search). Not in the U.S. nor in the UK or Canada.

The same thing happened when I tried “bad girls blog.” The shaded bar is painted half green, perhaps indicating moderate competition (As you can see, it is hard to know what it actually indicates. The question is: why doesn’t Google reveal the real number of bidders on each keyword? Why is it a secret in the first place?) At any event, you expect some competition when the bar is half green, don’t you? But again, there is not even one ad for “bad girls blog” in all the English speaking countries.

It wouldn’t be so bad if Google were just a search engine. But Google charges millions of people billions of dollars for AdWords, and a smart advertiser has to rely on the data that Google gives them to make intelligent decisions regarding his/her advertising campaign. If these data are extremely inaccurate, there is a good chance that most advertisers who use AdWords are pouring a fortune into Google’s pockets to no avail.
