The page repeats the promise that earned the click.
Someone who taps an ad for a mattress with two free pillows expects to land on that offer, with the pillows in plain sight. If they land on your homepage, or on a product page that never mentions the free pillows, they start to wonder whether the offer was real. So the page opens with the ad's headline, the same photo and the same offer, in the same words.
It can lower what you pay for each click, too. Google's ad auction looks at the page your ad leads to, and Google says higher quality ads 'can often lead to lower CPCs.' So every page starts from a brief built on the ad itself: its headline, its offer and who it's aimed at.
- The ad's headline, photo and offer at the top of the page
- A page for each campaign or offer
- A brief built on the ad before design starts
