Landing page experience is AdWords’ measure of how well your website gives people who click your ads exactly what they’re looking for–quickly and effortlessly. Your landing page is the URL people arrive at after they click your ad, and the experience you offer affects your Ad Rank and therefore your CPC and position in the ad auction. Your ads may show less often (or not at all) if they point to websites that offer a poor user experience. Easy-to-navigate content is important factor which improves user experience.
Organize and design your page well, so people don’t have to hunt around for information. Make it quick and easy for people to order the product mentioned in your ad.

Help customers quickly find what they’re looking for by prioritizing the content that’s visible above-the-fold.
