- Get a prioritized speed fix list for a live page.
- When you already have a link and want the AI to work from it instead of starting from scratch.
- Reuse it as often as you like: fill in the blanks (url) with new details and copy again.
- With ChatGPT, Claude, Gemini and more, the AIs that support what this prompt needs.
How to use it
- Open chatgpt.com or claude.ai (or another AI listed here).
- Paste the link into the prompt where it says so. The AI needs web access for this (on by default in most apps).
- Fill in the highlighted blank ([URL]) below, or edit them after pasting.
- Copy the prompt, paste it into the chat and send.
- If the AI can't open the link, paste the page's HTML instead.

Prompt
Audit the performance of this page: [URL]. Look at what you can see of the page (HTML, scripts, images, fonts, third-party tags). Then give me: 1. The likely biggest causes of slow loading and layout shift, ranked by impact. 2. For each, the specific fix with code or config examples (image formats and sizes, lazy loading, font-display, preconnect, deferring scripts, caching headers). 3. Quick wins I can do in under an hour vs bigger changes. Say clearly which findings you verified from the page and which are educated guesses, and tell me to confirm with Lighthouse or PageSpeed Insights.
