How to choose what to optimize first

Prioritize optimization by focusing on high-impact, low-effort changes on pages that sit directly in the conversion funnel. Use an impact-effort matrix to score each opportunity on potential business impact and implementation difficulty, then start with the changes that move the most important metric with the least resource investment.

High-impact pages include pricing pages, checkout flows, product pages, and primary landing pages, because these sit closest to the revenue event and carry the most conversion traffic. Within those pages, look for drop-off points using analytics tools: if 60% of visitors leave between the pricing page and the signup form, that transition is the highest-priority optimization target. The PIE framework (Potential, Importance, Ease) provides a structured scoring method: Potential measures how much improvement is possible, Importance measures how valuable the traffic on that page is, and Ease measures how quickly the test can be implemented. Avoid the temptation to optimize low-traffic pages or secondary elements before addressing the primary conversion bottleneck. One well-designed test on a high-traffic checkout page will produce more learning and more revenue impact than ten tests on blog sidebar CTAs.
