Landing Page Conversion Audit Skill 安全审计

78Audit a live page (or a mockup) for the things that actually move conversion rate on paid traffic, and return a ranked fix list. Do not return a generic "add more social proof" list - every finding must name the element, the failure mode, and what to change it to.9

2526Ask for, or fetch, in this order. Note explicitly which you did not get, because it caps what you can claim:2728| Input | What it unlocks |29|---|---|30| Page URL | Everything below (fetch and read the rendered DOM, not just the HTML source) |31| Traffic source + a sample ad / keyword | Message-match check, the single highest-impact finding |32| Sessions and conversions over the last 14-30 days | Whether the problem is statistically real or noise |33| Funnel step drop-off numbers | Which step to audit at all |34| Device split | Whether to audit mobile-first (usually yes: paid social is 70-90% mobile) |35

3536If you only have the URL, say so in the output and mark every quantitative claim as an estimate.37

4142**A. Message match (ad → page)**43- Does the page headline repeat the ad's promise in the ad's own words? A mismatch here caps everything downstream and is the most common single leak on paid traffic.44- Does the page deliver the *specific* thing the ad promised, or a general homepage version of it?45- Is the offer visible without scrolling on a 390x844 viewport?4647**B. Above the fold, mobile**48- One clear promise, one clear CTA. Count the competing CTAs - more than one primary action is a leak.49- Is the CTA button reachable in the first viewport, or is it below a hero image?50- Load: is anything meaningful painted before ~2.5s LCP? Slow hero video/images on paid social is a silent 10-30% loss.51

7071**G. Measurement (check this even though it is not a conversion leak)**72- Is a conversion event firing at all? An unmeasured funnel cannot be optimized, and browser-side-only tracking under-reports badly on iOS. See `server-side-conversion-tracking`.73- Is the click id (`fbclid` / `ttclid` / `gclid` / `msclkid`) carried from the landing page through to the order? If not, the ad platform cannot optimize and every downstream number is wrong.74

9697Rules for the report:98- Never claim a percentage lift for a specific fix. Say "expected direction" and rank relatively. Published lift numbers from case studies do not transfer.99- If sessions are under ~1,000 or conversions under ~30 in the window, state that the data cannot separate a real problem from noise, and rank by first-principles friction instead.100- Cap the "fix now" list at 7 items. A 30-item list does not get implemented.101
