Ana, the answer is clearly "looking for", because the subject is yourself.

Hello Ana The big question is CONTEXT. That is vital, because in different contexts, either statement could be correct.

Going after is more often used when you're chasing something or pressing charges against someone. I'd rather use the looking for in your situation.

Ana, in that case, I would actually use neither. I would say: I am not sure who they are targeting, but I am clearly not part of that demographic. Something like that. 'Demographic' might be a bit too technical, so you could then just say 'target market'. In informal speech, you can repeat words at times.

There are many kinds of English Americans have their way of speaking and British have their way buh I think they’re both correct
