Who writes copy for personal development? I plan on writing in the personal development space, but my specialty is writing sales letters about self-help books. Do you think my niche is lucaritive? I know self-help books are already hot right now, but do you think it's a profitable niche?
These type of books are only viable if the author is personally successful. If the author is not, then the thing fails as it should.
This niche is very lucrative but it is demanding at the same time. If you write about personal development, then you yourself should be personally developed. Otherwise, nobody will trust you and your ideas described in the book.
My reading tells me that the personal development/self-help niche will grow over the next few years. The thing to keep in mind is that people tend to buy from marketers they know and trust. If you don't already have a developed brand (or name as mentioned) you'll have to do something about that before you can succeed.
Nowadays I would say that this niche is more than lucrative and you will have a lot of opportunities here if you proceed with it properly and if you target the right audience for it and on the right platforms. So, before you start promoting your texts, just make some kind of a strategy on where to advertise them so that you can reach people that are interested in this topic. Paid ads would be helpful in this case as well.
