5)There is an important aspect in SEO called Link Exchange.Sites submit their url in link directories to exchange links with websites.But on a common basis sites from one category are not allowed to exchange links with sites from another category.
I want to know more about link exchange, link directories and their role in increasing targeted traffic.
