Here's the answer from the biggest benchmark in the field, 41,000 pages and 57 million conversions: the median landing page converts 6.6 percent of visitors, ecommerce at 4.2, and the spread between median and best is mostly fundamentals done properly. No exotic tricks appear in the top quartile. These are medians, not promises, but the craft is learnable.
The anatomy is seven blocks, top to bottom: a headline stating the visitor's desired outcome in their words, not your product's name. A subhead saying how and for whom. One call to action repeated down the page, and no navigation menu, because landing pages have one job. Proof with real numbers and real faces, never synthetic. The mechanism in three skimmable steps. The top three objections answered where they occur. And the closing call to action with a risk-reverser.
The invisible converter is message match: the page must continue the sentence the visitor clicked. An ad promising DMs answered while you sleep that lands on a generic services page leaks most of its traffic in three seconds. Every traffic source gets its own headline variant, which costs nothing now that pages render from a saved brief.
And mine the copy from customer language: the best-converting headline is usually a cleaned-up version of something a customer already said in a review or DM.
Then measure like an operator: conversion counted at the action, one change per week maximum, headline first. If visitors bounce, the first suspect isn't the page. It's the promise that brought them.

One page with a job beats a site with a menu.
