Low speed score: what do I fix first?

What you may see

The speed report is full of red items

Most likely cause

Many items are small; a few explain most of the score.

Check first (about two minutes)

Run the report on the phone profile for your main page and save it.

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a senior web performance engineer who explains speed problems to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM
Low speed score: what do I fix first?

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Many items are small; a few explain most of the score.

DO THESE STEPS, IN THIS ORDER
1. Sort the opportunities by estimated saving and take only the top three.
2. For each, explain in plain words and fix it, measuring before and after.
3. Ignore items that do not matter to my visitors, and tell me why.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The score improves for the top three items and the page is not visually different.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not cheat the score.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?
