You do not want to drive traffic from your ads to a generic landing page. Ideally, every different kind of message you have in a Google or Facebook ad, that same message is carried over to the landing page that the ad leads to. You want what the person searches for, what they see in the ad, and what they see on the landing page to all match.
That’s what Google refers to as your Quality Score and you can increase that by making sure all these areas remain consistent.
