• For each ad, you specify a final URL to determine the landing page where people are taken when they click your ad.
• Google's policy is that your landing page and display URL (the webpage shown in your ad) must share the same domain.
• Your landing page experience is one of several factors that helps determine a keyword's Quality Score. The experience of a landing page is represented by such things as the usefulness and relevance of information provided on the page, ease of navigation for the user, and how many links are on the page.
