Ask Do freelance platforms have a rule about how quickly you must respond to a client message?

[Edward22]

I have noticed that response time seems to matter a lot on most freelance platforms, even when no one tells you the exact rule upfront. Some platforms show your response rate openly on your profile, which makes clients judge you before they even read your bio. It makes me wonder if there is an actual written rule about how fast you are expected to reply or if it is just an unwritten expectation that affects your ranking. How does your platform handle this?
