The short answer
Write the landing page after choosing the channel and audience. A generic homepage is rarely enough for early growth experiments because each audience needs different proof and language.
Answer
How do I create landing pages for campaigns?
Create campaign landing pages by matching one audience, one problem, one promise, and one CTA. The page should feel like the natural next step from the ad, post, reply, or search query that brought the visitor there.
