AdSense Accelerator

This is the first tool featured here that’s not free. At $47 a month, this may be
more than you’re ready to invest in if you’re just getting started in AdSense.
However, if you’re looking for ways to build a Web site based on high-paying
keywords, you may want to make the investment.
The AdSense Accelerator shows the bids for the top-ten placement ads on
Google. You can then use this information to ensure that you’re targeting the
right keywords — which aren’t necessarily the top ten. Keep this in mind:
Just because a keyword is in the top ten doesn’t mean that it’s the right keyword
for you to target.
Basing your Web pages on the highest-paying keywords is a constant frustration
because those keywords change daily. However, you can use the
AdSense Accelerator to figure out which keywords consistently pay out at
higher rates.
No contract’s involved, so I suggest trying it out for at least a month to discover
more about what you could do to improve keyword targeting for the
ads that you want to display on your Web pages.
