Jane knows that her campaigns will be more efficient if she improves her quality score. How can Jane do this?

The selected answer options are correct because improving the ad relevance, expected click-through rate (CTR), and landing page experience are key factors in improving a campaign's quality score in Microsoft Advertising. Ad relevance refers to how closely the ad copy matches the user's search intent, and making the ad copy more relevant can lead to a better quality score by aligning the ad content with what users are looking for. Expected click-through rate is another important factor, as higher CTR indicates that users find the ad compelling and are more likely to click on it. Microsoft Advertising rewards advertisers with higher CTR because it signals to the platform that the ad is likely to be engaging. Finally, the landing page experience is crucial; a relevant, user-friendly landing page that provides a good experience for visitors helps increase the chances of conversion and thus contributes to a higher quality score. While increasing bids may improve ad placement, it does not directly influence the quality score and is therefore not a method to improve it. Quality score is more strongly impacted by the relevance and performance of the ad and landing page rather than just the bid amount.
