Hello, I have a question for people with any experience in Adwords.

Around last monday I re-started one of my campaigns. Changed the landing page, and tightened up my keywords and ad. My CTR shot up from around 2.0% to 8.0% (rough figures), and my ranking also climbed. This was without touching my CPC which remained around 0.06. Well, around Wed I wake up and check my campaigns, and I see 0 hits, 0 impressions. It turns out they shut off all my keywords and required a min bid of 0.30 to turn them back on.. that was at best, some required $1.00+

So I get one of the reps in live chat and ask, maybe it was a bug or something, and he tells me my quality score dropped, so my keywords were de-activated. If I wanted them activated again I had to pay the minimum and then if my QS increases, I can lower my CPC.

Wtf?

I don't understand how this makes a bit of sense. I looked up Quality Score in help, and it says
"Quality Score is determined by your keyword's clickthrough rate (CTR), relevance of your ad text, historical keyword performance, the quality of your ad's landing page, and other relevancy factors"

Well my CTR was fine. My Ad Text was extremely relevant to my landing page. (It's not like I was promoting black girls and sending them to a shemale landing page), and historically the campaign ran around 2.0% with a 6-7 avg ranking or so with a 0.07 CPC. Thousands of clicks, so it had quite a history.

So I ask, what are 'other relevancy factors', or is this some common thing Google has been doing since they changed to their new inactive keyword program (opposed to 'in trial', etc). Is there a way to get my ad back running w/o paying 0.30c per click? I activated around 6 keywords today at 0.30 cpc just to see if maybe i'd get actual lower amounts, but sure enough my ads ranked #1, and was 0.30 every click. I don't know what to do, any help? Thanks
