I'm looking for the different ways of increasing the QS of the landing pages I use. Is it really possible to reach the 10/10 (or 9 or 8). Any key ideas I have to follow?
QS is heavily weighted to CTR. Increase your CTR with more attractive ads, you'll have a higher QS. Learn more.
One trick for increases quality score is to separate high and low performing keywords. This is especially important when creating new accounts or launching new products. By isolating keywords, with say, a QS of 7 and higher, you will drive up the QS of the campaign, thus the words will follow. By isolating the low performers, you can test ad copy and try to drive the ctr up these words. 99% of Quality Score is Click Through Rate, Google rewards you for having a keyword that is directly related to the search query, to the ad, to what you are selling. Many People make this harder than it needs to be. A/B testing ads is something that you need to do to drive up your CTR's and thus drive up your QS.
