Performance Budgets for Catalog Pages

Daniel Kowalski11 May 2026

Performance Budgets for Catalog Pages

Speed affects conversion even in B2B. A catalog page that takes seconds to load wastes the time of people who order all day.

Set limits and enforce them

Define budgets for page weight, JavaScript size and key timings, then check them in your build pipeline. Budgets turn performance from a vague aim into a pass or fail criterion.

Fix the usual suspects

Oversized images, blocking scripts and unbounded third-party tags cause most slowdowns. Serve responsive images in modern formats, defer what is not needed and audit tags regularly.

Key takeaways

  • Define and automate performance budgets

  • Optimize images first

  • Audit third-party scripts
