I wouldn’t try to do all of them Just pick a handful of the big ones, or the relevant ones where you would want to be featured and perhaps where you believe you customers may think to find you.
Try turning things around, if you were wanting to find details about a game studio that had made your favourite game, where would be the first place you might look?
To some degree it may also depend on what you share, or plan to share, in the future.
I’d personally certainly want to be found easily via a web search.
A quick way to do some research for this would be to check out a few of the studios behind some of the big, well known games and see what they are doing.
If you have loads I think it won’t be as good as having a select few, but those having interesting and frequently updated content. If I see something which hasn’t been updated for months I often assume it’s dead etc.
Considerations for what gets posted/shared too will be important, any kind of questions / support type things should probably be limited to personal accounts. Progress on games, prototypes, artwork, video of game play those would all be interesting and related content. News on new projects and especially of completion, linking to where the games can be found (Google / Apple stores etc).
On a personal note you may, if you have one, want to update a LinkedIn profile of your own and mention employment at the Studio, providing web links to it and so on (when you’re all set up).
