Adwords Help - QS Droped From 10/10 to 1/10 overnight??

People need to understand that QS is mostly tied to your CTR as well as the CTR of your competitors. There are many other factors as well such as landing page, but the weight is very small.

Dropping from 10 to 1 in QS is a bummer. You say you have a CTR of at most 0.4%. I assume that's search since QS does not (yet) apply to the content network. That's very low CTR and in the old days, your ads would not be shown for failing the minimum CTR requirement.

Without seeing your campaign, I put the blame on poor ads resulting in poor CTR. Google has revised your QS having passed some threshold of impressions. So create better ads. I don't suggest putting your time yet working on your page. I have many high QS on keywords that did not appear anywhere on the landing page, although the theme of the page match the keywords.

As for new domain/account, there is no need for that. It also won't solve your problem by just copying. Your problem is almost for sure with your ads.

No need to start a new campaign or group. Simply create new ads to test in your current campaign. 90% of managing a campaign is doing just that: testing different ads.

As far as I know, there is no QS penalty for duplicate content. The most important factor in quality score is your CTR relative to competitors for that position. Therefore, a QS of 1 means that almost everybody else has a better CTR than you. Doesn't matter what your CTR is, it could be 1% or 5%. It means that compared to them, your ad is poor.

If your QS went from 10 to 1 its not because of CTR or any other normal criteria. It's a penalty. It was most certainly a planned manual review and in general it means Google doesn't like your offer and/or your promotion method. It happens mainly with affiliate sites and dishonest products like "free trials", where the customer gets mostly a bad product on a rebill procedure, while thinking he gets it for free. You see, the most important strategy for Google is to keep their searchers happy at all costs.

If you have your own site, often the reason is that your landingpage is not providing value on its own and works as a "bridge page" to an affiliate offer. Value is not seen as a short review.

If you have your own product and its not an affiliate site, then you most certainly did something wrong regarding their TOS. For instance collecting data without giving a right privacy policy.

It is interesting to get the reason why it happens and you could write a polite email to your support or call. But the general advice is to start over with a new domain, and dont make the same mistakes again. If you are for instance promoting cpa offers you might just start again and expect to see a slap in some weeks.

What happens with many cpa/affiliate promos at the moment is basically a joke since you see a new domain and an offer, after 3-4 weeks it gets slapped and there it is again with a new domain and the process repeats itself. I think Google will soon be smart enough to avoid those kind of affiliate offers altogether, much to the dispair of the CPA networks.

I'm surprised you are getting that many impressions on such a long keyword. It may also be part of your problem in that you don't have enough of them in your ad. Try shorted tailed like "garmin nuvi 680 gps". I can't think of any negatives for this as it's pretty specific. What are the negatives you are using?

I'm also confused about your CTR. In your original post, you mention 0.1% and your last, you say 80-100 clicks in 1000 impressions which would be 8-10%.

Sorry, I missed the 's.

Yes, if you are getting poor results from search partners, it would be wise to turn that off. In general, I found traffic from search partners has lower CTR and lower conversions. When the reverse is true, I wish we could have search partner campaigns only. I also wish that Google would show data for each in the reports. That would go a long way in optimizing a campaign.
