A great guide from the folks at Stripe for effective landing page copy.
Some total non-brainers in there but they bear repeating.
Landing pages often say “we offer” or “our solution,” which focuses on the wrong thing—your company, not your customers. Go through each sentence in your copy and rewrite it to address your customers. One way to do this is to begin with the word “you.” Another tip is to start your sentence with a verb. Focusing on them nearly guarantees that your copy will address—and speak to—your visitor.
