Google Adsense Tips make money from website

Basically, a public service adis an ad that Google
places in an AdSense ad block when there are
no appropriate ads to be displayed in that space
at that time. One time when you’re likely to see
public service ads is when you’ve first added the
AdSense code to your Web site.

In order to serve ads to your Web page that
match the content of the page, Google periodically
 examines — or crawls— the site to
determine the content of the site. Then ads are
pushed out to your Web site based on that content.
 When you’ve first put the AdSense code on
your site, it takes a few hours (and sometimes
even a couple of days) for Google to crawl the
site to examine the content. Until that happens,
the company wants somethingdisplayed in the
space that you’ve made available, so public
service ads are the filler

One way that you can get users to click
your ads is to ensure they appear in the right
 context on your Web site. In Chapter 3, you
find out about building content-rich Web sites
 and how you can optimize your Web site
 content for AdSense. Use those tips to help
 create pages that are complemented by the
ads Google dishes out to your site.
