I don't think I can try writing whatever is making those bloggers the most money, I just can't.
While part of earning is quality content, another is down to popularity.
I can guarantee that a lot of those people making a hundred buck per post have been here for years and posting regularly for that time.
The two best pieces of advice that i can give for a new person starting are to engage on other posts. It's how you get popular and the other part is to take part in the splinterlands competitions where you can get large votes for creating good content. They do two a week and the votes are large. The have a share your battle challenge and a separate splinterlands promo challenge every week.
