A condensed version of our full playbook post, mapped to what RoboHost automates vs what you handle.
Automated for you
- Image compression + WebP (LCP weight)
- Script defer + lazy images (render-blocking, LCP)
- Cache headers + compression (TTFB on repeats)
- Minified assets (parse time → INP)
Your part
- CLS: set width/height on images and embeds in your markup
- LCP: keep the hero element near the top of the DOM
- INP: limit third-party scripts — each tag is someone else's JavaScript on your main thread
