What is Google’s PageRank?


If you have ever done any reading about search engine optimization or were just curious how you can get your site to the top of the Google search engine results, understanding PageRank is vital. I’m going to introduce you to the basics of PageRank and also provide a brief discussion on how much you should really worry about PageRank if you are running a website or Internet business.

Google’s founders, Larry Page and Sergey Brin, invented PageRank and it forms the basis for how Google works. Google didn’t become the best search engine in the world by chance, it became the best search engine because it provided the best results. PageRank is in fact the technology that gave Google its competitor-killing edge, a way to greatly improve the accuracy and validity of a search response to a user query.

What is MozRank

MozRank represents a link popularity score. It reflects the importance of any given web page on the Internet. Pages earn MozRank by the number and quality of other pages that link to them. The higher the quality of the incoming links, the higher the MozRank.

How is MozRank scored?

We calculate this score on a logarithmic scale between 0 and 10. Thus, it's much easier to improve from a MozRank of 3 to 4 than it is to improve from 8 to 9. An "average" MozRank of what most people think of as a normal page on the Internet is around 3.

How can MozRank be improved?

A web page's MozRank can be improved by getting lots of links from semi-popular pages or a few links from very popular pages.


How does Spam Score work?

Over the last year, our data science team, led by Dr. Matt Peters, examined a great number of potential factors that predicted that a site might be penalized or banned by Google. We found strong correlations with 17 unique factors we call "spam flags," and turned them into a score.

Almost every subdomain in Mozscape (our web index) now has a Spam Score attached to it, and this score is viewable inside Open Site Explorer (and soon, the MozBar and other tools). The score is simple; it just records the quantity of spam flags the subdomain triggers. Our correlations showed that no particular flag was more likely than others to mean a domain was penalized/banned in Google, but firing many flags had a very strong correlation (you can see the math below).

Spam Score currently operates only on the subdomain level—we don't have it for pages or root domains. It's been my experience and the experience of many other SEOs in the field that a great deal of link spam is tied to the subdomain-level. There are plenty of exceptions—manipulative links can and do live on plenty of high-quality sites—but as we've tested, we found that subdomain-level Spam Score was the best solution we could create at web scale. It does a solid job with the most obvious, nastiest spam, and a decent job highlighting risk in other areas, too.

The SISTRIX Visibility Index is a reference number for a domain’s visibility in Google’s search result pages. The higher the value, the more visitors the domain is expected to gain from Google.

The Visibility index is therefore extremely well suited to measure and rate the success of SEO-actions or to analyse the consequences of changes to the Google algorithm.

You are also able to perform meaningful competition analyses with its aid. Due to this, you can, for example, identify the most successful websites in one segment, which are then consulted as Best-Practice examples (orientation towards the best) to increase one’s own success. This way, proven, optimal, or exemplary SEO-methods can be recognised and adapted.


What is Backlink?

In search engine optimization (SEO) terminology a backlink is a hyperlink that links from a Web page, back to your own Web page or Web site. Also called an Inbound Link (IBL) these links are important in determining the popularity (or importance) of your Web site. Some search engines, including Google will consider Web sites with more backlinks more relevant in search results pages. May also be written as two separate words, back link.


What is Majestic?

Majestic SEO is one of the best link intelligence tools available to website owners today and the best part is that it’s free, at least a big part of it is, and definitely holds it’s own against tools such as Linkscape from SEOMoz and link data from RavenTools. First we are going to cover ways to use Majestic SEO on your own link data and then your competitors, so you should already have an account set up and your website verified..
