Message match is most of it
The headline should repeat the promise of the ad almost word for word. Every mismatch between ad and page is a moment where the visitor re-evaluates whether they are in the right place.
One decision per page
Navigation, secondary offers and footer link farms all leak intent. A paid landing page has one job. Give it one action and remove everything competing with it.
Proof beats adjectives
Specific numbers, named clients and real screenshots outperform every superlative. If you cannot name the client, name the number.
Test structure before you test buttons
Button colour tests are theatre. Test the offer, the headline and the order of the page. Those are the variables with enough effect size to reach significance before the quarter ends.
