Internal Structures and Linkages

If we recognise that PageRank is really about pages having a vote, then straight away we can derive one important thing about internal link structure and PageRank:

A page that is in the Google index has a vote, however small. Thus, the more

pages you have in the index – the more overall vote you are likely to have. Or,

simply put, bigger sites tend to hold a greater total amount of PageRank within

their site (as they have more pages to work with).

We need to clarify this a bit more. To get a high PageRank, it is not enough to 

have tens of thousands of pages. Those pages must also be in Google’s index. 

To achieve this they must contain enough content for Google’s algorithms to 

consider them worthy of being added to the index. As you develop content for 

your site, you are also creating more PageRank for your site. It’s hard work, and 

you’re creating it slowly – but if you’re also creating pages that people will want to 

link to, then you’re doing yourself two favours at once: PageRank from both 

directions. Or, to put it in very basic terms:

The best “internal” thing you can do to build PageRank is to write lots of good

content. Ensure that pages aren’t overly short or overly long and break the

content into several pages where necessary.

There are three different ways in which pages can be interlinked within a site. In 

practice, sites might use a combination of these. Using a combination is 

fine and normal as long as you understand the different sections and how they

 are affecting your PageRank.
