Hi, Displaying an ad on a page with live chat might result a violation of "dynamic content" but I see that in some cases there are ads on pages with chat (or Instant messenger), Any recommendations for a page with a chat and a lot of traffic?
Google ads, search boxes or search results may not be:
•Placed in emails, email programs, including webmail, or on pages where dynamic content (such as live chat, instant messaging, or auto-refreshing comments) is the primary focus. (Does not apply to AdMob.)
Main problem with live chat is that it's not modded and plenty of times "content" created through live chat can go against adsense rules. So, they just made it against all live chat in general to save the hassle.
Do it and get caught and you probably will receive perm ban for that particular site.
Use other ads instead of adsense is the safest bet on your dynamic chat screen. If the site has lots of traffic, don't risk adsense standing and eligibility for your other pages 'leading' to the eventual chat screen.
Think of others ways to work adsense into your site through looking and observing your user behaviors. Do they visit other pages? etc.
