2. Domain authority and page authority. Next, you should learn about domain authority and page authority, and how they predict your site’s search rankings. Here’s the basic idea; your site’s domain authority is a proprietary score, provided by Moz, of how “trustworthy” your domain is. It’s calculated based on the quantity and quality of inbound links to your website. The higher it is, the higher all your pages across your domain are likely to rank in organic search results. Page authority is very similar, but page-specific, and you can use it to engineer a link architecture that strategically favors some of your pages over others. Authority depends on the authority and volume of inbound links.
DisabledGO, an information provider for people with disabilities in the UK and Ireland, hired Agency51 to implement an SEO migration strategy to move DisabledGO from an old platform to a new one. By applying 301 redirects to old URLS, transferring metadata, setting up Google webmaster tools, and creating a new sitemap, Agency 51 was able to successfully transfer DisabledGO to a new platform while keeping their previous SEO power alive. Additionally, they were able to boost visitor numbers by 21% year over year, and the site restructuring allowed DisabledGO to rank higher than competitors. Their case study is available on SingleGrain.com.
Steve, sometimes good information to users is a consolidation of very high quality links. We have over 3000 links to small business sites within the SBA as well as links to the Harvard and Yale library, academic journals, etc. But because we have the understanding that there should be no more than a hundred links in a website (more now from what Matt said) we have used nofollow on all of them out of fear that Google will penalize our site because of the amount of links.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
