The following are the quickest and most efficient strategies I will utilize to improve the quality score a few notches:  By improving the relevance of the landing pages: The landing page is the component of the Quality Score that determines whether the campaign passes or fails. Spending time on a strong and improved landing page will only have a minor effect. If the page is really terrible, it is necessary to look for and solve the evident problem. For instance, if the landing page just contains an e-mail address, then we need to add some extra content, information, and links so that users may learn more about the advertiser before electing to share their information with the company.  By creating relevant and interesting advertising copy: Write relevant and appealing ad language, and use the top-scoring keywords within an ad group in the headline, description, and URL slug of your ad. This allows the person searching to see their search term in the ad content, boosting their likelihood of clicking on the ad and so raising CTR.  Better keyword structure: By doing stronger keyword research, you can establish the correct foundation for your campaigns, which will ultimately make your keywords more relevant to your ad copy and landing sites.
