Website Progression

Hi, im a newbie and im getting a bit overwhelmed by the information regarding setting up the blog. im sure that
when people start off they tend to have very few articles , and their designs would be much different from
what they have started? do people start off with hefty number of articles at the start? or can they progress
with few articles for SEO purpose? and the most important thing is that what would the layout be
at the start of the website design, im sure they wont be any homepage displaying articles from different
categories as there are only few articles so do we keep the blog page as the front page? please explain guys! thanks
