Question About Tags

I hear mixed reviews on whether to use tags to promote your game/make your game more searchable.

When talking about tags, are these just keywords in the title and description of your game? And do they have to be in the format of “#tag” or “tag”.

The downside I hear is adding tags make the developer seem desperate. I would think you could easily add keywords within sentences of the description and it wouldn’t look weird.

I imagine this is what they think would look desperate, for example: #roblox #game #videogame #phone #console #obby #platform
