The quick rundown of the top ten, followed by my personal comments in red:
- Don't click your own ads: It is amazing how many people don't realize this is a problem even if they are "truly interested" in what is being advertised.
- Don't ask others to click on Google ads: You'd think this was obvious, but not the publisher. Few weeks ago I saw a huge 250x500 pixel image reminding visitors to click at least three ads a day, or else their free access to the site might be gone the following day.
- Don't employ pop-up prompts or automatic software installations: Sneaky pop-ups containing AdSense or reminders to click the ads have been hitting the radar recently.
- Be aware of how your site is promoted:This seems to be reminding those publishers who are utilizing spy ware to promote their site with AdSense ads as being against the AdSense terms and policies.
- Don't place Google ads on sites that contain prohibited content: No comments!
- Respect Google trademarks:Reminding publishers who are utilizing Google logos etc about their brand guidelines.
- Don't tamper with the AdSense code:It is always amazing how frequently people change the JavaScript yet don't realize it is against the AdSense terms.
- Provide a positive user experience: Someone should remind the publisher who bombarded me with eight pop ups, a full complement of Google ads and about two sentences of keyword spam content on the page.
- Provide a good environment for advertisers:About creating pages advertisers would be happy to see their ads appearing on.
- Be responsive:If Google emails you with an account or policy issue, respond as soon as possible.
