Most early-stage landing pages are written like a product spec sheet: here's what it does, here's what it's made of, here's the price. That's not what gets someone to buy something they've never heard of.
A landing page has exactly one job at each stage of the visit: get the next scroll, then get the next click, then get the order. Everything on the page should be doing one of those three things — or it shouldn't be on the page.
They open with the founder's story instead of the buyer's problem. Story matters — but it's the second thing a stranger needs to hear, not the first. Lead with what changes for them, then earn the right to tell them who you are.
The second most common mistake: one page trying to serve every stage of the funnel. A cold visitor from an ad and a warm visitor from a retargeting email need different amounts of context. If you only have one page, at minimum let the top third do the convincing and push the "why us" deeper down, not first.
