Some Quick Tips for New Users
- Google prefers pages with lots of text rather than lots of pictures, because it can better assess what kind of ads will be interesting to your visitors.
- If you want to see how your ads look before they go live, you can check them on an online test server. But keep in mind that if the server is connected to the Internet, Google can see your pages, so it can, and will, index them.
- Google's online help pages for AdSense (https://www.google.com/adsense/online-help) are chock-full of useful information on setting up shop, getting the most out of the program, maintaining your account, troubleshooting, and so on. Visit every so often, especially before you write in for help. If you have a question that isn't answered by the help pages or is specific to your account, drop the AdSense crew a line using the form at https://google.com/adsense/contact.
- For more help, including instructions on blocking robots other than the Googlebot, check the Troubleshooting Tips section of the "Google AdSense Technical Implementation Guide" at https://www.google.com/adsense/faq-tech.
