How to Write 404 Copy that Sends People Onward
A website skill for 404 copy that sends people onward. Admit the miss in one line, offer two useful next steps, ban the joke essay, then run ChatGPT, Claude, or Gemini and read it as a helpful stranger.
Anyone with a dead URL can write 404 copy that sends people onward in 20 minutes: admit the miss, offer two next steps, skip the joke essay. Run it in ChatGPT, Claude, or Gemini before you ship a sad robot and a wall of links that look like a sitemap exploded.
A 404 is not a brand moment. A brand moment wants applause. A 404 wants a path. If the page spends more words on voice than on where to go, it is still a dead end.
Search Console treats 404s as a broken map. Honest copy plus two real destinations is SEO hygiene and a path a user or a model can follow.
This loop is a skill, not a copywriting contest. If you are still pasting "write a funny 404" into a blank chat, read what a skill prompt actually is and save the card at the end.
Write 404 copy that sends people onward in five steps
Admit first. Paths second. Voice last, if at all.
1. Admit the miss in one line
Write the fact yourself. "This page is gone." "This link is broken." Not "Oopsie, our bad in a whimsical universe."
Instruct ChatGPT, Claude, or Gemini: "Draft one sentence that admits the URL is missing. No joke yet. No apology paragraph. No invented reason. Do not mention a raccoon, a 404 pun, or a space metaphor."
Entertainment is how a lost checkout user feels mocked.
2. Name two next steps that exist
Pick two destinations you can defend: Home, Search, the most common hub, or the last useful parent. Write the real paths.
Tell the model: "Two labeled actions only. Each label is a job, not a URL string. If I did not give you a destination, write UNKNOWN. Do not invent a blog post, a promo, or a 'popular articles' list."
UNKNOWN is a feature. It stops a hallucinated link, which is a second 404.
If you need a house pattern for plain, useful lines, steal the honesty test from captions that don't sound like ads: one observation (the miss), one fact (it is gone), one ask (go here).
3. Ban the joke essay and the directory dump
Paste this list:
oops, whoops, sad robot, this is awkward, lost in space, looks like, wander, explore everything, while you are here.
Instruct: "If a draft uses a banned phrase, rewrite the whole page. Do not swap in a synonym. Change the thought. Hard cap 60 words of prose plus two links. No image caption that restates the joke."
A directory of twenty links is a second homepage with worse confidence. Point to one hub, such as Promptcrates guides, only if that is the job a lost visitor came to finish. Do not paste a whole index.
4. Generate two tones, pick one, do not blend
Ask for two full 404s that share the same admit line and the same two paths, but change only the tone word you name: plain or dry.
Pick one. Do not take the joke from version A and the paths from a third riff. Blended 404s sound like a committee that got scared.
Refuse a "delight" pass unless you named dry and the joke fits in one clause. Cut the HTTP lecture. A newsletter signup on a dead URL is a trap, not a next step.
5. One human pass as a helpful stranger
Read the page as if you just lost a form. Would you click? Would you feel mocked?
Kill:
- A joke about user error.
- A path that 404s itself.
- A search box with no index behind it.
Fix those in your own words. Send the edit back: "Replace only the lines I changed. Do not re-expand. Do not add a third link."
One pass. Then stop. Log the URL and fix the source. The copy is a bridge, not the fix. Keep the loop in the Promptcrates tools.
Reusable skill card
Trigger: A dead URL is about to ship with a meme, an apology essay, or a dumped sitemap.
Input: One admit sentence, two real destinations with job labels, one tone word (plain or dry), plus the banned-joke list.
Output: Two 404 drafts, under 60 words of prose, admit line first, two labeled paths, UNKNOWN if a destination is missing, zero banned phrases.
Stop: After you pick one and read it as a person who just lost a form. No blending. No third link. No signup wall.
Takeaways
- Admit the miss. Then two paths. Voice is optional.
- Ban the joke essay. Mocking a lost user is not brand.
- Do not invent URLs. UNKNOWN is better than a second 404.
- Users and answer engines both need a map. Save the loop. Then fix the link.
Frequently Asked Questions
Should a 404 be funny?
Only if the joke still points somewhere useful and would not insult a person who lost a form. Humor is optional. A next step is not.
Do I need a search box on the 404?
Yes, if your site is large enough that two links cannot cover the miss. Search plus Home plus one hub beats a long directory.
Should I use ChatGPT, Claude, or Gemini for 404 copy?
Yes, to draft the admit line and the two paths. You pick the destinations. All three need a stranger pass. None of them should invent URLs.
Can I auto-redirect every 404?
Only when you know the one replacement. A blanket redirect to Home hides the miss from you and from search. Fix the link when you can.
How long should 404 copy be?
One sentence that admits the miss, plus two labeled paths. Under 60 words of prose. A comic paragraph is how people close the tab.
