I've had an adwords account that has been idle for about 4 months now, and I'm just getting around to setting an ad up in it. For the search network, it's asking for a minimum bid of $10 (!) for every keyword. Is this related to how long my account has been inactive? Is there something I can do about this? Thanks in advance.
No the length of your account being inactive should have nothing to do with this. I think this is the problem: http://webtov.com/blog/adwords-5-and-10-minimum-bids-what-2007-07-04/
This has been covered hundreds of times in this forum and has a clearly defined answer in the sticky FAQ.
