Today I got many of my best keywords in different campaigns go from Great to Poor (with $10 bids!!!!).
Some of these keywords were running for months under Great. I did not make any changes on the landing

pages neither (since months).

What is also weird is that this switch (Great to Poor) is happening across campaigns of unrelated products

(going to the same site).

Anyone of you experienced in this problem ? give me a solution pls?

There was a new update on the quality score system so you must be affected. You will pay the minimum bid

per click and it was not go down unless it's not a quality score problem. And also Sometimes the quality

score fails with some sites or you only have to change a small thing. Good luck!
