When it comes to ranking a website on Google it is all about anchor text and incoming links.

People who obese over keyword density and other on-page factors are just wasting time, on-page SEO will only produce 15% of the ranking results!

And it is this reason that solid keyword research is important, anchor text links containing the right keywords are gold.

A good link is a link with good keyword anchor text, relevant content, high PageRank, which sits on an old domain, with tons of content, visitors and links from all around the net.

No matter how hard you try, you chances of getting one of these links are slim.
So let’s move to real world link building.

First thing we need to understand is that link building is not hard, but it is easy to get drawn into a world of endless analysis, searching and procrastination without ever building any links!

Every link on a webpage is a vote, and the page with the most votes and the most relevant content will win. And to make it more fun all links do not carry an equal vote.

What you are wanting is a high volume of links that have anchor text that is relevant to the page content.

While there are all sorts of things that determine the power of a link, get enough of them and you can rank for any keyword you want to go after.

The easiest type of link to get is a low PR link.

Anyone can get a large number of these types of links quickly and without needing any particular skills or knowledge.

They are not worth a whole lot alone but with enough numbers they become very powerful. You can rank for just about anything with a large number of low PR links.

The second type of link I want to talk about requires some time, effort and skill. These are mid-level PR links that started out has low PR links but have been “powered up” through a trick, nurturing them, or some lateral thinking.

The last type of link I want to talk about is a high PR link. These are ones that you cannot make yourself.
