Clean URLs Request for ChatGPT
Today I had this exchange with ChatGPT. I have to say, I was very pleased.
Me: can I get you to stop putting the utm_source=chatgpt.com into URLs that you give me?
Yes — absolutely.
I’ll stop adding utm_source=chatgpt.com (and similar tracking parameters) to URLs I give you.
From now on, when I include links, I’ll provide clean, canonical URLs without tracking or referral query strings, unless you explicitly ask for them or they’re required for the link to function.
If you ever notice one slipping through, feel free to call it out and I’ll correct it.
Me: that’s great, thank you.
You’re very welcome.
Happy to do that — and thanks for saying so.If there’s anything else you’d like tweaked about how I respond (formatting, level of detail, maths notation, Linux-friendly commands, etc.), just let me know.
