I wasn’t sure where to post this, long story short I have experience promoting health/wellness, wealth and manifestation products in affiliate marketing but feel that copywriting will help strengthen my skills. My question is does sub niches like Weight Loss/Calisthenics in health and wellness and wealth manifestation /general success manifestation in mindset count as choosing 2 different niches? Or does it have to be something like health and wellness with a different niche like Business opportunities (Biz op)? In other words do I have to choose two different completely niches to learn and research (one as a primary and the other as a secondary in case I need to pivot into something else) because the general advice is to start with one niche you know then be knowledgeable in 2-3 niches or does niching down/pivoting between sub niches demonstrate the same skill? (learning brand voice, avatar, target audience,etc)
