Linkscape: Reverse Engineering the Search Engines - Linkscape Metrics and Data
(Page 2 of 4 )
This is a summary of the metrics used and data provided by Linkscape.
mozRank (mR)
As stated above, this is a copy of Google's Pagerank, Yahoo! WebRank and Live's StaticRank. It computes the link popularity of pages throughout the web and offers data for everyone to see!
External mozRank
Link-juice flow is equal for internal and external links, but it's also important to know the flow of link juice only from external websites. This is what "external mozRank" does.
Domain Juice (DJ)
Domain Juice is the sum of mozRanks for all URLs in a domain. It uses a 10 point scale. Domain Juice does not include external links in calculations.
External Domain Juice
This measure calculates the sum of all mozRanks from all external links flowing to a particular domain. External Domain Juice measures ranking power for an entire domain as opposed to separate web pages.
mozTrust (mT)
This is a reverse-engineered Google Trust Rank algorithm. Google Trust Rank works on the principle of "seeds," where humans manually identify trusted seed pages, and links from those seed pages pass "trust rank" to other pages. The further a page is from the "seed," the less trust is passed.
It's not clear if Linkscape uses humans to identify seed pages. There's also a chance that a page considered a seed at SEO moz may not be such in Google's eyes.
Domain-Level mozTrust (DmT)
This is exactly the same measurement as above, but on a domain level. This algorithm is used by Google, since new pages with 0 links from authoritative and trusted domains rank high in search results for relatively competitive 3 - 5 word long terms.
URLs
The URL report shows data for the top 2,500 URLs, with links to domains and 500 pages with links to a specific URL. The data represents most important links, according to SEO Moz algorithms.
Anchor Text Distribution
This checks the anchor text of each of the links in a report.
Link & URL Attributes:
Here's the link data offered with LinkScape:
