No Cervical Mucus 8 Weeks Pregnant

In 2006 it was widely spoken of the theorem Randfish, with whom we had approached (albeit very mild) to the algorithm of Google.

This theorem is named after its creator and that is the owner and operator of seomoz.org , who rely on its expertise in search engine optimization, had tried to write a formula that sums up all the factors that might be present in the algorithm of Google.

Randfish The theorem is based on a simplistic , but to keep in mind, sum of several factors to get high rankings in search engines. to these factors, below, is assigned a weight according to their importance.

The Randfish Theorem:

Google
score = (Using Keywords - 0.3) +
(Importance domain - 0.25) +
(Link Input - 0.25) +
(data users - 0.1) +
(Quality of content - 0.1) +
(manual push) -
(Automatic & Manual Penalties)

factors in the use of keywords (Keywords):


* Keywords in title tag
* Words chiave nei tag degli header
* Parole chiave nel testo del documento
* Parole chiave nei link interni che puntano alla pagina
* Parole chiave nel nome di dominio e/o nell’indirizzo della pagina (URL)

Importanza del dominio:

* Storia della registrazione
* Età del dominio
* Importanza dei link che puntano al dominio
* Rilevanza del dominio sull’argomento basata sui link in entrata ed in uscita
* Utilizzo storico & pattern dei link verso il dominio

Punteggio dei link in entrata:


* Età dei link
* Qualità dei domini che mandano il link
* Qualità of pages sending links
* Text links
* Assessment of the quantity / weight of the link (Pagerank or its variations)
* Score on the subject of the pages / sites that send the link

data users:

* History of the percentage of clicks (CTR) on the page in search engine search

* Time spent by users on the page
* Number of searches for URL / domain * Change
visits / use of URL / name of the
domain users that Google can monitor (toolbar, wifi, analytics, etc.).

score of quality of content:


* Potentially given by hand searches and the most popular pages
* Supplied by internal evaluators of Google (see Henk) *
automated algorithms to evaluate the text (quality, readability, etc.).

This is not a perfect representation of 'algorithm, but there is a strong feeling that the real algorithm, it may be composed of many of these factors in the calculation.


How many are the factors that bind to the history of Randfish
