Tiene importancia el PageRank

¿Tiene importancia el PageRank?
El PageRank es una medida inventada por los creadores de Google para saber que importancia tiene tu Web y que sitio le otorga en la presentación de sus búsquedas, y como entenderás no es lo mismo el primero puesto que el 1245.
Tan bien tendremos en cuenta que esto sirve mucho y de forma importante, si yo busco mi Blog en Google por el titulo exacto del Blog naturalmente salgo el primero pero si pongo buscar Android, seguramente ni salga.

 Esto para una empresa es muy importante no es lo mismo “portátil acer aspire 5740”, que si que saldrá la pagina de hacer y el modelo que quiero comprar, que poner “portátil”, aquí el que se lleva el gato al agua es el primero de la lista de web encontradas, y puede ser acer o cualquier otro fabricante.
En este momento es cuando uno valora el PageRank, es muy sencillo pocas personas buscan el portátil por fabricante y modelo y millones de personas buscan por “portátil” a secas.
Esto quiere decir que los primeros de las paginas buscadas con palabras menos concretas y genéricas tendrán millones de visitas.
Al tener 10/10, por ejemplo en un sitio que trate acerca de "manuales", quiere decir que si alguien busca sobre el tema, tu sitio sería el primero en consultarse.

¿Cómo funcionan las actualizaciones del Google PageRank?

La barra nos muestra un PageRank en base 10 en una escala logarítmica. Es decir, es fácil subir de 0 a 1 ó de 2 a 3, pero en cambio es muy difícil subir de 5 a 6, y aun más de 6 a 7. Pero este no es el PageRank real de nuestra página, sino el valor que Google le asignó la última vez que actualizó el PageRank y para esto trabajan a diario en Google pero solo publican los resultados cada 3 meses.
