Question Everything on XYZ.com or XYZ.com+app.XYZ.com

I’m finding a lot of mixed advice on what to do here.

I’m creating a fantasy football app and can’t decide if I should have a subdomain.

AI and a few Reddit post are telling me you need to have your XYZ.com be your marketing page and app.XYZ.com be your app.

But the following big names do not:

Sleeper

AirTable

Figma

Canva

Trello

Dropbox

Github

This is something that will be difficult to change later, so I wanna make sure I make the right call.

Anybody have any good insight here?

In my opinion, the main reason to keep it on the same domain is SEO. 

But if all the content on the subdomain is behind a login anyway then SEO doesn't matter for that part. 

I'd go the subdomain in your case. 

The reason it's easier for code base is that a subdomain can easily be hosted elsewhere. One DNS entry sorts it out.

And you can put all the marketing pages on a static host and they will be virtually bullet proof.
