Thank you! I usually change it every three months, but I did'nt know if that was too often! Thanks for the advice!It depends on how often you do it. Like every 3 months? Every month?
Every three months or seasonally could be a good idea. People like consistency and sometimes longevity of one certain thing. With channel art it may be difficult because many YouTubers usually change their art when they update their channel content, like a reboot, sort of. It can also be good because some people like to see new things quite often. I say you shall do it as you please, I'm sure you will be fine!
