Well, I have Expert Seo System (SEO analysis software) and, when I create reports analysing some keywords, I realize page 1 is dominated by:
Big Brands containing...
Millions of pages indexed and...
Shared by dozens or hundreds of social network users.
So, yeah, it's needed. Only problem is: how can I create a big brand website, containing millions of pages indexed (with high quality content!) and shared by dozens or hundreds social users with my budget (I have USD 19.50 in my wallet now)?
Be or not be... This is the question.
