I want to change my site's domain because I feel the current name no longer fits what the site has become. Almost none of my traffic comes from people searching for the brand name; it's almost entirely organic search traffic for the topic itself.

If I 301-redirect every URL on the old domain to its exact equivalent on the new one, will my rankings take a significant hit? Or, if I use the Change of Address tool in GSC and handle the migration cleanly, should the impact be minimal?

What is your experience on domain change for a website that depends on search traffic?
