I'm still having a lot of success avoiding slaps but the key is to set up the account slowly. Like put in 4 or 5 keywords that you can get AWESOME click through rates on (set up for search ONLY, not content network or search partners) and wait till you get some good history in the account before putting more keywords in there.

I've also had a couple times when I just COULD NOT get keywords activated. When I talked with google about it it seems that the keywords just have too much negative history with OTHER advertisers and they simply don't let people advertise on those terms or something. Weird.

If you want me to look at your landing page you could PM me and I'll take a look see if I can offer any input
