AdSence-importance of keyword placement

  Just  Color Picker, use the Select Corner Style drop-down
menu to specify how you want the corners of your ads to look: square,
slightly rounded, or very rounded.

Select the channel you want to use to track your ad and then click
Continue.

On the next page, enter a new name for your ad  and then
click the Submit and Get Code button to generate the code
for the ad.

Copy and paste the ad code generated into the HTML on your
 Web site.
These steps are okay for most situations, one little problem
with using the Color Picker to determine colors for your
 ad elements: Your color choices are somewhat limited.

The palette that Google makes available
to you shows only about 60 colors out of the hundreds
that a browser can display. You’re not limited to those 60,
 though. You can further customize your colors by entering
 the hexadecimal number for the color you want displayed.

After you finish researching your keywords and then
 selecting the most valuable — those worth most to your
pocketbook — and the most appropriate words for your
 Web site, you have to actually integrate them into your Web
site. Using those valuable and appropriate keywords in your
site’s content is good practice, and more information about
 how to use those words in your content.

Metatags where keywords should appear include the following:
Title metatags
Description metatags
Keyword metatags
Heading metatags
Alt text
Now, for those of you out there who are faint-of-heart when it comes to HTML
coding, be aware that you need to physically place these metatags (with the
exception of the alt text) in the top section of the HTML code of your Web
page, between the tags that indicate the head of your page.

Text ads are so appealing  and certainly the main
reason they perform so well when compared to the other
 types of ads that AdSense makes available  is because
 text ads can be made to blend well into your Web page.
