The Quality Score is a measurement of how relevant your ads, keywords, and landing page that links from the ad to your website are to a user seeing your ad through the Google AdWords platform.
Landing pages usually have a call-to-action: a "Buy Now" button, a "Download Now" or a registration form where you ask users to fill in information about them.
This means that most landing pages, either used through a Google AdWords campaign or not, collect personal data from visiting users. If you ask for information from users through a web form, it's a direct transfer of data.
Most companies choose to do this through the footer section of their websites:
It states that the "Quality Score" given to your ads is based on your landing page user experience which includes factors such as:
A well-designed landing page can give you a better score on the ad campaigns. Having a good score means that you'll pay less for running the campaigns.
While remarketing can be a great way to attract past visitors back to your site, you should inform these people that you gather information for remarketing or similar audiences on your website.
The AdWords system regularly reviews your ads and landing pages and probably your website in order to "score" the user experience. For example, disabling the AdWords' bot can get your account suspended from AdWords campaigns:
By default, the AdWords system reviews advertised landing pages to assess landing page experience. If you don't want some of your landing pages to be reviewed, you can follow the steps below to restrict the AdWords system from visiting those pages. However, if you do this, you may end up with a significant drop in Quality Score because we won't have as much information to determine your landing page experience and relevance.
This means your ads may show far less often unless you significantly increase your maximum cost-per-click (in shorthand, your bid). Even with higher bids, however, it is unlikely your ads would show very often and may not even show at all.
Also note that if you restrict access to your entire site, or if you restrict access to so many of your landing pages that it makes it difficult for the AdWords system to meaningfully review your account, your site will be suspended.
Amazon is placing its "Privacy Notice" in the footer section across all its web pages of the website:
While not "officially" required by AdWords to have this kind of legal agreement on any of your landing pages or even the entire website, doing so be used successfully to increase your Quality Score.
You're being transparent with your users about what data you're gathering from them. This is a checklist point that the AdWords system consider when measuring the user experience of the landing page.
