Quality score is a rating Google gives your ads on a scale of one to ten. It measures how relevant your ad, your keyword, and your landing page are to each other. A score of seven or above is generally considered good. The higher your quality score, the less you pay per click, which means your budget goes further. A low quality score means Google sees your ad as less relevant, so you pay more for the same clicks. Improving your landing page and making your ad copy match your keyword closely are the best ways to raise it. What score are you currently getting on your campaigns?
