All of my quality scores dropped??

I have 300+ keywords on my campaign, most were 8/10-10/10 quality score. A couple days later, most of them dropped to 4/10 and 5/10, with my highest being 7/10, and even a few 3/10. I don't know what the problem is... Any ideas?

 

Bump and..

Could this be because my CTR decreased from 3% to 1.5% over the past week? Not sure if it would lower my QS's that much though..

 

You would need to paste a couple of examples of your ads, and the landing page used.

I would assume it was google giving you the benefit of the doubt until they finally crawled your site and realized that the content was not related to the ads you are using..

 

Most of QS is CTR so yes, a drop in CTR will see a drop in QS.

 

I'm assuming you aren't promoting anything that Google doesn't like, correct?

For example risk-free trials or scammy "make a million in a month" kinda products

 

If he was, his QS would be 1 across the board. A one is the off switch meaning you are violating one or more rules.

 

Yep, definitely nor promoting anything like that. I'm promoting a legitimate service

 

i think you should check your backlinks may be you loss some backlinks or it can be a kind of negitive marketing.
