I 200 Fattori SEO per il Ranking di un Sito

Durante una conferenza Mutt Cutts (“il vescovo” :D) dichiarò che Google utilizzava all’incirca 200 fattori per determinare il ranking di un sito.
Dopo questa affermazione molti hanno cercato di stilare una lista dettagliata, credo che la prima apparsa in rete sia quella di WebmasterWorld che riporto :

Domain

* Age of domain
* History of domain
* Keywords in domain name
* IP address of domain
* Location of IP address / Server

Architecture

* HTML structure
* Use of Headers tags
* URL path
* Use of external CSS / JavaScript files

Content

* Keyword density of page
* Keywords in Title Tag
* Keywords in Meta Description (Not Meta Keywords)
* Keywords in header tags (H1, H2 etc)
* Keywords in body text
* Freshness of content

Per Inbound Link

* Quality of website inbound linking
* Quality of web page inbound linking
* Age of website
* Age of web page
* Relevancy of page’s content
* Location of link (Footer, Navigation, Body text)
* Anchor text of link
* Title attribute of link
* ALT tag of images linking
* Country specific top level domain
* Authority of top level domain (.edu, .gov)
* Location of server
* Authority links (CNN, BBC, etc)

Cluster of Links

* Uniqueness of class C IP address

Internal Cross Linking

* Number of internal links to page
* Location of link on page
* Anchor text of FIRST text link

* Over optimisation
* Purchasing links

* Performance / Load of a website
* Speed of Javascript

Misconceptions

* XML Sitemap (Aids the crawler but doesn’t help rankings)
* PageRank (General indicator of page’s performance)

E’ una lista molto interessante da cui prendere comunque spunto 😉
