The Landing Page Is Half the Auction
Quality Score has three inputs, and one of them isn't in the ad account at all. Landing Page Experience is judged on relevance to the searcher's intent, transparency about the offer and the business, and ease of use on any device — and it feeds directly into what you pay per click.
This is where most agencies stop, because the landing page belongs to someone else. We build them, so we do not have to. A campaign pointed at a page that loads slowly, buries the offer, or answers a different question than the one that was searched is a campaign paying a tax on every click — and that page is also the exact place where paid clicks quietly stop becoming phone calls.
