Since more and more publishers are worried about being suspended from AdSense, and it seems like even more publishers claim they "didn't know" the rules because they didn't read the terms and/or policies, the AdSense team has created a brand new top ten list of what to do (and not to do!) to ensure your AdSense account remains in good standing.
The quick rundown of the top ten, as well as some of my personal comments in italics with each:
Don't click your own ads I have been saying this ever since AdSense launched. 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 Again, you'd think this was obvious, but not the the publisher I saw a few months ago with 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 utlizing spyware 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 I still see AdSense showing up on adult or gambling sites these days.
Respect Google trademarks Reminding publishers who are utlizing 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 bombaded me with eight popups, 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 ASAP :)
You can read the full What can I do to ensure that my account won't be disabled? including clarifications about each of these top ten items, so you can ensure you are following the most important terms and policies, since these are the ones that publishers most commonly run afoul with which result in suspended AdSense accounts.
