If I create a filter that only tracks subdomains like: sub.domain.com, will it also track visitors on domain.com/sub ?

Or do I have to create a second filter for that?

Probably not and probably yes.

Why don't you set different goal funnels for your different sub domains. It will make your tracking better.

I suggest that you just create another filter for it for better result.

IO think you need to create another filter which track the sub domains. Because subdomain is the complete seprate website which has no relation now with domain. If your domain has millions of back links then it cant be profitable for the sub domain.

Sub domain is different from a sub directory. So, you might want to use different filters.

Subdomain and domain these two are different websites, so I suggest you that you can create two separate filters for each one.
