Measure before you tune
Use field-oriented data when you can (CrUX, Search Console) and lab tools for debugging. Know whether LCP, INP, or CLS is the real pain on mobile.
High-leverage fixes
- Choose hosting that fits your traffic and caching model.
- Compress and correctly size images; lazy-load below-the-fold media.
- Remove unused plugins and scripts — especially heavy page-builder extras on key templates.
- Cache pages for anonymous visitors; keep ecommerce/cart paths correctly excluded.
- Audit third-party tags; delay non-essential scripts.
Template discipline
Homepage hero videos, autoloading carousels, and unbounded query loops destroy performance. Design for content editors with constraints: image size guidance, limited blocks, and reusable patterns.
After changes, re-test the templates that earn money — not only the homepage in a desktop lab score.
