I created a campaign and its now active but with ads its coming "Trade Mark, limited " and my ads are not showing..What is this ? why ads not showing after approval ??
You should check Google trademark policy: http://adwords.google.com/support/aw/bin/answer.py?hl=en&answer=6118
As stated above, sounds like you tried to use a trademarked term, change that term to something else and you should be ok.
yeah, per their policy you can(at the moment) bid on trademark terms but can't use these terms in the ad itself. This will probably hurt your click thru rates, so I would suggest looking for other terms that can be used synonmously..
