It is easy to fixate on the ad — the headlines, the keywords, the bid. But the ad's only job is to earn a click. What happens after the click decides whether you get a customer or just a bill. That "after" is the landing page, and its quality is one of the most under-appreciated levers in all of paid search.
Google agrees enough to score it. Landing page experience is one of the three factors that make up your Quality Score, right alongside expected click-through rate and ad relevance. A poor landing page experience drags down your Quality Score, which raises your costs and lowers your positions — so a bad page hurts you twice: it fails to convert visitors and it makes your ads more expensive.
