A landing page is not only a design screen. It is a sequence of decisions: what is the offer, why should a visitor trust it, what happens next, and how easy is it to contact the team.
The main CTA should appear in the hero, after the value blocks, near proof, and again before the final section. Repetition helps visitors act when they are ready.
Performance is part of conversion. Heavy assets, script-only content, and slow first render can damage both paid traffic results and organic visibility.
