Have you ever got this? My best keywords have only ever been 9/10, but I don't know why as Google just says it's great but not how to improve. I have the keywords in my text, titles even website name. Does 10/10 really exist?

10/10 does exist, but if you're consistently getting 9/10 you're doing pretty good. Google can't tell you exactly how to improve since they want to keep their algorithm a secret. They want to help, but they can't tell you everything or it becomes too easy to manipulate and take advantage of their system.

Thanks!

I have managed to get 8/10 but looking at this thread would love to take one more step

I've got 10 out of 10 but have plenty of keywords around the 8 mark.

Try doing the three variations of the keyword
keyword
"keyword"
[keyord]

start eliminating the ones that have a poor ctr on them and that should start pushing your QS up.

Also use
-keyword to elimate useless impressions. You only need so many impressions as you need clicks. Watch what keyword expressions click on your ad and elimate the ones that are no good. Ie the wrong type or location.

hey great yar i have managed o get only 7/10, now i will go further and like to have 10/10 for.....

yes, I have two keywords 10/10 Quality Score, but they don't convert

I manage to get 8/10 as my max.....I have my keywords in title, ad text, URL, website..

Even i have heard if you optimize your website from SEO perspective and get some backlinks and do the basic on-page optimization .....that also helps in good quality score in adwords...

i have three keywords which have 8/10 quality score.

I saw a video where you can pay by impression. Has anyone does this and if so does it help to save money? and do you get more for what you pay for?
