how to build an autonomous landing page engine that self improves from competitor churn:
1/ set up the
@firecrawl MCP with cron/routine to run scheduled scrapes. pull from G2. Trustpilot. Reddit. forums.
extract EXACT cancellation phrases into a living churn database refreshed weekly.
2/ run multi agent analysis in claude.
cluster complaints by purchase friction.
run 5 synthetic buyer panels to score candidate copy against current PostHog baselines.
test the skeptic. the price checker. the comparison shopper.
3/ auto generate modular page component packages.
→ a pain inversion headline using an exact 4 word churn phrase
→ an uncropped UI screenshot showing the specific fix
→ an objection-handling block tailored to that competitor's flaw.
4/ deploy Next.js edge middleware. personalize the page in real time.
match the variant to the incoming ad creative ID. UTM parameters. search intent. PostHog user traits.
5/ connect the
@posthog MCP to run HogQL power calculations. set a hard volume floor ie 400 conversions per variant to call a valid 20% lift. default stance is underpowered until the math clears.
6/ auto promote winning variants via feature flags. route 80% of ad spend to the winner. feed the winning copy back into your Meta ad pipeline.
treat CRO like a continuous data engineering loop
