Hello everyone, I am in the process of creating an authority niche site. In this niche, there are 25 or so main topics that I want to post about (it's an educational niche). Would I be better making the site and starting with 10 or so articles and adding another every week or so, or should I just add them all at once? Are there any benefits or drawbacks doing it one way or another? One other related question is, as this is an educational site and this niche has these 25 topics, once they're all posted there won't be a great deal of fresh content I can add. Is it possible to grab and maintain a top Google ranking without adding this fresh content? Thanks in advance.
