I would like to pause my adwords campaigns for a few weeks, but I am afraid that I will loose the CTR and quality score. Is there a good way of doing that?

I thought of lowering my budget to retain CTR, but I have 5 campaigns with 10 adgroups each. My cost per click is about $1.90. i.e. it would still be a pretty substantial budget just to keep everything ticking.

Any ideas? How long would it take to regain a good quality score after pausing a campaign?

Thanks!!!

Mark
