Is search marketing old enough to have a good old days? If it is, then I remember them. Ah, the days when you could fire up the Overture keyword tool to see how many searches were done in the U.S. on Yahoo! for a particular keyword. Add a little math, and you could estimate the number of searches done across all U.S. search engines in a month. But then Yahoo! crippled that free tool, and we've been left with no way to project keyword demand, until now.


Bill Hunt, my co-author of Search Engine Marketing, Inc. worked with his team at Global Strategies International to estimate keywords using Google's free keyword tool. The good news is that this technique allows you to estimate keyword demand for any country where Google is used, not just the U.S., but the bad news is that it is an arcane and time-consuming procedure that requires you to click your heart out before you extract the information.

If you're wondering why you'd want to project keyword demand, that's simple. Keyword demand is the number of searches on a particular search keyword done in a period of time, such as "3,000 U.S. searches per month for the keyword Mike Moran" (I wish). By understanding the number of searches for a keyword, it can help you know which ones are most worth concentrating on.

For example, years ago when I worked with IBM to sell their ThinkPad computers online, it was extremely valuable to know that the keyword laptop was far more popular than notebook because then we could optimize for the word that more searchers used.

But you can do a lot more with keyword demand. If you have an estimate of how many searches are done each month, you can take guesses at how many visitors you might get to your site by improving your search marketing. And you can project from there how many people might buy something. Keyword demand is the basis of convincing yourself that the time, effort, and money required for successful search marketing is worth it.

Before moving on to the procedure, remember that even though we are using Google's tool, Google is not promising that any of these numbers are accurate--in fact, there's no real way to test the accuracy of these numbers anyway. But it gives you a good idea of where you stand--better than any other free tool can do.

Oh, and one more thing: What Google giveth, Google can taketh away. eth.

At any moment, Google might decide to change the way its tool works. If that happens, we'll try to update the procedure so that you can do something else. But as we found out with Yahoo!'s treatment of the Overture tool, it's hard to know what to do when the old method breaks. At first, the Overture keyword tool became a bit unreliable--it ran slowly and started to time out a lot--then the numbers were frozen in time in January of 2007. Later in 2007, the URL begin to yield 404s all the time. To this day, I am not sure that Yahoo! has made any announcement that the tool was ever withdrawn. The same thing could happen to this procedure that works with Google's tool.

But, at least it works now, and it is the best free alternative you've got. If you're willing to pay for information, Wordtracker, Trellian's Keyword Discovery, and other tools provide numbers that help you estimate keyword demand, but my favorite price is always free.

So, check out the free guide to estimating keyword demand. Let me know if it works for you.

Why can't you just go here:

Then you can do all of the calculation at the end of what they say. It is a lot easier and not that time consuming. There is also the SEObook.com keyword tool that is free and helps out with this.

Gee, Tim, that sure looks a lot easier. I will check with Bill to see if there's a reason why we shouldn't use that, but it could be that he (like me) did not know about it. Thanks for bringing it to my attention. If it looks good, I'll update the post with the new information. Thanks for sharing this resource with everyone.

I don't see how anyone could estimate that Google would base their prediction on "it takes 100 clicks to get a paid search click", when you consider that the ad would be in the first position. I did the math (working backwards) on a high volume exact match term where I know we are at the top of the listings for all impressions tells me that this Google tool is estimating CTR to be around 5%. But that was just for this term... most likely it varies greatly by term.

The way I estimate impressions is to compare a term whose volume I know with the new term in Google Trends.

Thanks for the comment, Chris. Bill's team has tested this and believes that this is the most accurate multiplier for the broadest number of terms. I agree with you that it will vary a lot term by term, but Bill's company has seen the best results with this formula.

Hi Mike, if you are Ok with global predictions (not just US), you can use the free keyword suggestion tool from Wordtracker.

http://freekeywords.wordtracker.com/

Not to be confused with their free trial, this is a free tool that shows the predicted searches per day for the top 100 keywords relating to a seed keyword. It is exactly the same dataset as their paid tool. Captcha kicks in after a number of searches, but not right up front.

Tim, Google has now confirmed that the tool you discovered is a permanent change to their policy that eliminates the need to go through the histrionics that I documented on my site (http://adwords.blogspot.com/2008/07/keyword-tool-updated-with-search-volume.html). Thanks to Tim for spotting this even before Google came clean about it.
