I have previously talked about internal linking and how you can increase your search engine rankings by improving your internal linking structure. This article will focus on how to distribute your page authority flow to optimize the search engine rankings.
What is page authority?
Every page that has been indexed by the search engines receives a certain amount of authority. Search engines calculate the authority different one from another but in general the most important factor of getting page authority is to have good inbound links to your site from other websites.
Page authority in Google is called PageRank. PR is calculated on an article by article basis rather than on a site by site basis. So your home page might have a PR5 ranking, while your most recent article might have PR0.
How does the link juice work?
Each page passes link juice (authority) and each linked page gets the authority. If your PR5 main page links to 10 different sites, each of these 10 links, internal and external, is going to get an equal amount of PR. So the higher the PR of the page that is linking and the fewer links the page links to, the more authority the linked page will receive from the link.
In general, the more internal pages you are linking to from each page, and the fewer external links you are linking to, the more authority your site will maintain as a whole, as authority will continue to circulate around your pages.
Note that link juice is passed through all links. Every single linked page from your site receives a percentage of the PR assigned from the page you link from. Each link counts, including “Contact Page” or “Email This” link and does take up the authority of your original page.
So for you it is important to consider all the different pages you link to on your blog. Think about which pages are important to you, which pages would you like to rank high in search engines and which pages deserve the passed authority.
How do I prevent link juice leakage?
The “nofollow” attribute on individual links is a mechanism that gives bloggers the ability to modify link juice/authority flow. For Google, nofollow links are dropped out of the link graph and are not counted.
You can employ nofollow attribute on your sites to limit the amount of link juice that flows out of your page to external pages on different domains, or you can use it to control where the link juice will flow to within your site and the internal pages.
How do I use the nofollow attribute?
Add the rel=”nofollow” attribute in the links you do not want to send the link juice to. Add the rel=”nofollow” attribute to all the links that you do not want to be taking from the authority that could be recycled back onto your site.
This is how a normal link looks like:
This is how a link with rel=”nofollow” attribute looks like:
<a rel=”nofollow” href=”http://www.google.com”>Google</a>
Hopefully, this is another step of search engines optimization of your site, that will eventually result in your site ranking high for your content relevant keywords.
