Again the same thread - Keywords are not active! Sorry to cianuro. I don't find any answer for my problem with the sticky here! My keywords are not active for more than 1 week. My daily budget is $20! I tried with 3 different campaigns (2 are campaigns from clickbank..) Quality score for all my keywords are : Great! This is the case for more than a week! In case if Adwords ppl will trigger my keywords after manual review, will it take more than a week? (I really don't know ) your ad delivery is being spaced throughout the day - What is this? This is another reason given by Adwords for my ads not showing. Help plz...
your ad delivery is being spaced throughout the day this means your budget isn't enough to allow your ads to be shown everytime your keyword is searched for, so google show it periodically through the day. If that's the case, you should see impressions.
That would be kind of dumb ientrepreneur - if you haven't already check all this stuff: http://adwords.google.com/support/bin/topic.py?topic=24
