Fix · Speed

My website is slow

Blocks your work

What you may see

The page takes many seconds to show on a phone
It feels fast on my computer and slow for customers

Most likely cause

Most slowness comes from a few big things: huge images, too much script, slow server answers, or fonts and videos loading early.

Check first (about two minutes)

Test the live page with a speed tool on a phone profile and write the top three findings.
Open the Network tab and sort by size: what are the five biggest files?

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.

MOST LIKELY CAUSE
Most slowness comes from a few big things: huge images, too much script, slow server answers, or fonts and videos loading early.

DO THESE STEPS, IN THIS ORDER
1. Measure first: record the load time, total page weight and the five biggest files on a throttled phone connection.
2. Fix the biggest cause first (usually images: right size, modern format, lazy loading below the fold, width and height set).
3. Then reduce scripts (remove unused packages and third-party scripts), keep fonts light, and make the server answer fast (cache).
4. Measure again and report before and after for each change. Make one change at a time.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The load time and page weight are clearly lower than the first measurement on the same phone profile, and the page looks the same.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not change the design or remove content to score higher.
- 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?
