Resume exact promise
If an ad promises a selection for a specific need, the landing page must show this selection and the criteria that justify it. A generic title followed by a complete catalog forces the visitor to redo the sorting. Choose an offer and an audience before design.
Reassure before the button
Show price, content, variants, delivery, returns and help available at the moment when doubt arises. A demonstration or example of use can be more useful than a big slogan. Don't invent a countdown timer, limited stock or testimonial.
Test the entire course
From a phone, open the ad, page, cart and checkout. Check price consistency and form errors. Track cart additions and attributable orders, but also look at the questions received: they often reveal what the page doesn't explain.
