Coaching in two different niches


Hi,
I can’t remember if it was a call in SCS or a podcast with Brooke, (I think it was a podcast) but one of her coaches had two different niches. I remember that she was coaching lawyers and perhaps women after divorce (unsure about this one). I’m just wondering if you’d recommend having two different websites for such different niches or if you’d just have different sections on the same website? How would you go about it?
I’m asking because I’m building a certain niche right now, however, I have a huge upcoming opportunity in a niche I’ve coached before with a large audience. I’m wondering if I’d undermine my credibility by sending people to a mixed website etc. All input will be appreciated. Thanks!
