AdWords Traffic Estimator and Bid Tool

https://adwords.google.com/select/trafficEstimatorSandbox
Remember AdWords? That’s the advertising side of AdSense. AdWords is
the program that advertisers use to place the ads that you show on your
Web site using the AdSense program. The AdWords Traffic Estimator and
Bid Tool is actually an AdWords tool, but because AdSense is the other side
of AdWords, you may find it useful to help determine which high-paying keywords
you should be targeting with your Web site.
It works simply enough. Enter a few bits of information into the form
provided — information like keywords, bid amount, and targeting location —
and then the program generates a report that shows you how much traffic can
be expected for an ad based around the keywords you provided. Here’s how
to use it:
1. Log in to the Web site listed at the beginning of this section.
2. Enter a list of keywords that you want to target in the text box provided,
as shown in Figure 17-2.
3. Enter a maximum cost-per-click in the Choose a Currency section.
You may have to use your imagination here, but don’t choose a costper-
click that’s too low or too high. Instead, think in terms of an average
cost. There are no averages for what users can expect to pay for the use
of a keyword, but my suggestion is to use a figure that’s no less than $1
per click and no more than $10 per click. You want to keep your options
as wide open as possible, but you can also experiment with the numbers
to see what you find.
4. (Optional) Enter a daily budget.
I don’t usually bother with this. I leave this blank so that I’m not limited
by the hypothetical budget because a daily budget is really only relevant
if you’re planning to use the AdWords service where you pay to have
your ads placed on Web sites.
5. Select your regional targeting — language, location, and countries —
and then click Continue.
A new page appears, displaying stats for the keywords that you selected.
You’ll see Average CPC, Estimated Clicks Per Day, and Estimated Cost
Per Day.
Use the statistics that are returned to get a feel for which keywords you have
under consideration that will pay the highest in terms of CPC and cost-perimpression.
Again, it’s not an exact science, but getting a feel for what advertisers
are paying helps you better understand what you can expect (very
roughly) as far as earnings are concerned.
