Domain Authority: What are Domain Authority and Total Page Reputation?

Total Page Reputation includes the PageRank of the Page and the PageRank of the website HomePage.

Relevance and Reputation



Positioning on Google is determined by a combination of ‘Reputation’ and ‘Relevance’. The Google algorithm is looking at both to determine the ranking of a webpage for a keyword.

  1. The total link value of links coming into the Webpage.

What is PageRank?


Google tells us that ‘PageRank is Google’s view of the importance of this page’.

PageRank is on a logarithmic scale. Those with the greatest reputation have a PageRank 10 and a new webpage has a PageRank0 when it is first indexed.

The best indication we are offered by Google  of Website Reputation (Website Authority – Domain Authority) is the PageRank of the HomePage of the website.

A HomePage that is competing for a keyword is allocated a minimum PageRank of 4.5. This means that:

  1. A new website can begin to be competitive for relatively low keyword difficulty keywords if it uses its HomePage.

The value of a link depends on

  1. The reputation of the page providing the link – PageRank of the linking page. This is the link power of that page.
  2. The number of outgoing links on the linking page – the more outgoing links the less the value of those links.

Part of search engine optimization is to increase the reputation of the webpage and website – off-page optimization.

The search engines would like all the links to be natural but if you develop a new website and wait for those links you may wait a very long time.


  1. The keywords (phrases).
  2. Words in the keywords.
  3. Synonyms.
  4. Associated words.

That are

  1. Visible on the webpage.
  2. Present in the underlying coding – particularly the Page Title.
  3. Present in the anchor (linking) text in incoming links to the webpage.


In SEO, as in life, reputation is even more important than relevance.

  • Relevance is largely about what you are and in SEO this equates to on-page optimization.
  • Reputation is what others say about you. To the search engines this means the links that others place on their website to specifically to your webpage and to your website in general.



Total Reputation of a webpage includes the Page Reputation of the page and the domain authority – best represented by the HomePage PageRank.
