Start with the bottleneck

Do not optimize every page at once. Find the biggest meaningful drop in the journey and ask why qualified users fail to move forward.

Measure transitions

Track the conversion between key steps: visit to lead, lead to call, sales page to checkout, checkout to purchase, purchase to upsell.

Offer, audience, traffic quality, headline, proof, friction and follow-up usually deserve attention before cosmetic tweaks.
