RICH BUILDING SITE CONTENTS

First of all, why would you want to build content-rich sites? The short answer is "because it makes people stay on your site for a while, and build an all-they come back again, and they tell their friends about the site."
but why? well, for one thing, people will survive in rich-content sites because it takes time to read one or two articles. become, while they read the entry site, sight their edge (the side) captures the small ads around the articles.
And if people start to realize that certain sites have fields that are attractive as they like, and in particular, the different fields that are constantly changed and updated, they will double-check what's new.
The worst thing in this world is to have a stagnant website that do not change. Exactly, people will visit a site twice-first for a look, and a second to check what changed and when they did not find anything that changed, they most likely will not return. Never.
