Majestic Seo user guide

majestic.com provides some of the most fantastic data that is available for Seo practitioners in the whole industry. Your SerpWorx toolbar contains all of the following metrics:

Majestic Seo explained

Trust Flow

A score based on quality, on a scale between 0-100. Majestic collated many trusted seed sites based on a manual review of the web. This process forms the foundation of Majestic Trust Flow. Sites closely linked to a trusted seed site can see higher scores, whereas sites that may have some questionable links would see a much lower score.

Citation Flow

A score between 0-100 which helps to measure the link equity or "power" the website or link carries. Citation flow is used in conjunction with "Trust Flow". Together the Citation Flow and Trust Flow form the Majestic Flow Metrics algorithm.

Trust Ratio

Trust Flow / Citation Flow = Trust Ratio
The basics behind why the trust ratio works is because, if the Citation Flow is high and the Trust Flow is low, this means that the website being checked has a lot of link equity (or "juice"), but barely any trust from those links. This usually indicates that the site has gained those links from "spammy" areas of the web as they are not close to authoritative sources.

Topical Trust Flow

This is a Majestic feature which provides website categorisation. Majestic has now categorised the web so users can see in which industry sector the website has influence. The Topical Trust Flow helps users find influencers for specific categories and easily determine if a link clean up is required. Topical Trust Flow provides a series of numbers, on a log based scale between 0-100. The number shows the relative influence of a web page, subdomain or root domain in any given topic or category.

Moz user guide

Moz Page Authority

Page Authority is a score (on a 100-point scale) developed by Moz that predicts how well a specific page will rank on search engines. It is based off data from the Mozscape web index and includes link counts, MozRank, MozTrust, and dozens of other factors. It uses a machine learning model to predictively find an algorithm that best correlates with rankings across the thousands of search results that we predict against.

Moz Domain Authority

Domain Authority is a score (on a 100-point scale) developed by Moz that predicts how well a website will rank on search engines. Use Domain Authority when comparing one site to another or tracking the "strength" of your website over time. We calculate this metric by combining all of our other link metrics—linking root domains, number of total links, MozRank, MozTrust, etc.—into a single score.

Moz Trust

MozTrust is Moz’s global link trust score. It is similar to MozRank, but rather than measuring link popularity, it measures link trust. Receiving links from sources with inherent trust—such as the home pages of major university websites or certain government web pages—is a strong trust endorsement.

Moz Rank

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.

Moz Spam Score

Moz Spam Score is a metric that indicates how likely a website is to be penalised by the search engines as a site that provides low value to searchers, as measured by the ratios of content to code, content to external links, external links to internal links, and several other factors.

URL Rating

URL Rating shows the strength on an individual URL’s backlink profile and is measured from 0-100 – with 0 being no authority (for example a brand new page with no inbound links) and 100 being the highest. This metric has the highest correlation with Google rankings, which means that pages with high UR tend to rank better in search engines.

Domain Rating

Domain Rating shows the overall strength of a site’s backlink profile and is measured from 0-100 – with 0 being no authority (for example a new site with no inbound links) and 100 being the highest. Backlinks from sites with high DR carry more "weight".

Anchor Cloud

When searching for the keyword "Web design" 12% of this pages total inbound links, i.e. 61.05k links, because this is an inner page, all have the exact match keyword "web design" as the anchor text in the backlinks. This means that this page has 61050 links x 12% = 7326 links have the exact match anchor text "web design."
