I've been working with Google's Adsense program for a while now. If you're
not already in the program, why not take a look at it now at
https://www.google.com/adsense. I really like Adsense. It makes me money and
it's easy to work with. Just some simple copy & paste into your webpage and
you're done. Right?

Wrong! You can do it that way if you want. Who knows? Maybe you'll get lucky
and get a lot of clicks. But if you're really serious about making a lot of
money with the program, you're going to have to tweak it a little.

I've invested quite a bit of time experimenting with the program. When I
first signed up, I got some clicks and made a tiny bit of money. That wasn't
good enough. I knew there must be a way to get more of my visitors to click
on the ads.

Google has a strict policy about not pointing to the ads in any way or
asking people to click on them, so there were two things I couldn't do. What
else was there?

Then I remembered reading an article once that discussed the psychological
impact of colors on the human mind. I started researching everything I could
find on the subject.

After a lot of reading, many tests and periods of watching my clicks go up
and down, I found the one color combination that seemed to work the best.

Testing previously done at supermarkets had revealed that the same product
could pull more sales from just changing the colors of the label. What were
these colors? Red and yellow! The combination of these two colors has an
immediate impact on the person who sees them. They make your eyes stop and
focus. They pull your eyes right to that part of the page. They grab your
attention! I'm not sure exactly why the combination of red and yellow does
this, but it does. On one of my sites, I changed my Adsense ads to a bright
red border and a yellow background with black text and URL.

My click through rate more than doubled with just that one simple change.
That's what worked on my site. Your site's color scheme may work better with
a slightly different color combination. Try lots of different color
variations. Make a change in the morning and let it ride for the whole day.
The next morning, try a different set of colors. Change the border,
background, text. Change everything you can. Most importantly, keep detailed
records of the color scheme you used, click ratio and revenue generated.

After you've done all the experimenting you want to, go back to the most
profitable one and let it run for a week or so and see how it does. I'm
always trying different colors even after my run of good clicks with red and
yellow. There are a lot of color combinations to choose from. You never know
when you'll find just the right one.
