Deliverables

  • Baseline report from field data and throttled mobile traces
  • Prioritised fixes with expected gain and effort
  • Critical CSS and render-path work
  • Image pipeline: formats, sizes and lazy-loading
  • Third-party script audit
  • A/B tests with a stated hypothesis and success metric

Process

  1. 01

    Measure

    Lighthouse on a throttled mobile profile plus field data - numbers before opinions.

  2. 02

    Find the blocker

    Usually a widget, an app or an oversized hero image - rarely the theme itself.

  3. 03

    Fix by payoff

    LCP first, then interaction, then layout shift - one change at a time.

  4. 04

    Report

    Including what did not move, so the next quarter starts from facts.
