PageRank is the most important indication of the power of back links but do you know where does the PR come from and how it is distributed? It’s important to know that to avoid mistakes when building links.
Links and PageRank
About Link Density
The number of outgoing links per page is an important metric. Too many links can render a backlink useless even if the PR of the page is high itself.
This is a very often overlooked aspect of link building so I feel like it deserves a dedicated post. Far too many inexperienced marketers think that PR is all that matters regardless of other metrics that a page has. Don’t underestimate the importance of link density.
Press Releases
While the most popular press release sites are paid and take a fee to post a press release, there are many press releases that you can submit content to and get a backlink from.
