You optimized the ad. The leak is downstream. The most common conversion killers we find in audits.你优化了广告，漏却在下游。这是我们在诊断里最常发现的转化杀手。
When we audit a struggling account, the problem is downstream of the ad more often than not. The targeting is fine, the creative is fine, and then the click lands on a page that fumbles it. Here are the leaks we see most.当我们诊断一个表现不佳的账户，问题往往出在广告的下游。定向没问题，素材也没问题，结果点击落到一个把它搞砸的页面上。以下是我们最常见到的几处漏点。
One: the page does not match the ad. If your ad promised a problem-first hook, the page should open on that problem — not a generic homepage. Message match is the single biggest CRO lever and the most ignored.一：页面与广告不匹配。如果你的广告用的是"先讲问题"的钩子，页面就该从那个问题开场——而不是一个通用首页。信息一致性是最大、也最被忽视的 CRO 杠杆。
Two: it is slow. Every second of load time costs you conversions on mobile, where most of your paid traffic lives. Three: too many choices — a page with five calls to action has none. Four: the offer is buried. Five: no proof — testimonials and numbers near the button do more than another paragraph of copy.二：太慢。在移动端——你大部分付费流量所在之处——每多一秒加载都在赔转化。三：选择太多——一个有五个行动号召的页面，等于没有。四：优惠被埋住了。五：没有信任背书——按钮旁的客户证言和数字，比再写一段文案更管用。
