Bing Ads quality score is an important component to focus on when optimizing your Bing Ads account.
A well managed account with good quality scores can help improve results, lower cost per click and save you time when managing your Bing Ads account.
Keep in mind that with Bing Ads, quality score is not a KPI (key performance indicator) but more of a diagnostic tool.

Think about it this way: 1) is my ad relevant to the search query? 2) can users find what they are looking for on my landing page?
