Link building is a process of improving website visibility and traffic. Usually, the more the links come to your site via different sources, the more traffic your site will receive. However, link building is a tedious process which requires proper allocation of resources and time. Also, awareness of effective link building techniques and their appropriate implementation can go a long way towards link popularity.
While implementing any link building technique (Article syndication, blog posting, and forum participation), the major emphasis area should be determining the value and relevance of webpage where your link would be.
Typically, we consider Google Page Rank as an indicator of quality and authority site. However, in case of link development, it should not be a parameter of website selection for backlinks. Sometimes link from PR0 could be more valuable than PR7. And the reason is links value on a page depends on total number of links (inbound +outbound) on that page.
In most of the cases high PR webpage carry large number of outbound links that reduce the effectiveness of individual links on that page, as Google recommends only 100 links per page. Although, links from authority sites such as.edu and.gov can aid extra points in overall brand value of your website.
Links from relevant sites are always regarded as best and more preferably those of the similar theme or from same industry. Nevertheless, links from entirely different theme can also help you if the site pointed to your site is renowned and authorized in its domain.
