My big question is this:

If I change my ad every couple of days to reflect special offers, will I be at a disadvantage?

I mean that:

1) My keywords are unchanged
2) My ads do not create enough impressions to generate a "history" before they are updated

Would running new ads cost me more? Google actively encourages us to improve, improve, improve...

Ad CTR, with time, affects keyword CTR. Things were fine as they were. The new algo only has a tiny impact on things from a surfer's viewpoint, but a big impact on Google's earnings from those who regularly update or try to improve their ads.

And here's a thought - by letting us choose to not change our ads very often, Google's editorial staff will have less of a backlog!
