What is Google Pagerank?

The Pagarank a website shows the popularity index, put numbers on a scale of 1 to 10 is measured by the importance of the site. From this simple premise is understood that the higher the value, we will have more relevance in the SERPs and therefore have more chance to get out on the first pages of search.

How to calculate PageRank?

For calcora the Pagerank is necessary to know the algorithm, namely formula mathematics that result in the value of PageRank.
PR X * 15
PR (X + 1) * 3

PR = Pagerank

This is the simplification of Forumula that, believe me, is much more complex!
In practice we have to read as follows:
To get a PR = 3 we must have at least 15 links from sites with PR = 3
Or from sites with PR 3 = 4

For related links and connections mean careful, PageRank may vary from page to page, so if such a site from which you receive a link on its home has a value of PR = 5 but the pages where your link is in the PR = first you have to consider the latter value and not the first.

How do you improve the Pagerank?

There are several ways to increase the value of PageRank shall list some here:

1. Buy banner or link from popular sites
2. Natural (sacrifices and so much sweat!)
3. Link Exchange (subject)

Now that we have an idea of ​​what the PageRank, imagine what would happens if your site had a value greater than PR = 6 we would have a greater number of visits due to the greater importance.
Google takes into account a set of values, of course these are within our site such as

* well done a very good code
* links to various social networks
* images with the ALT tag description
* internal links with descriptions
* use of keywords in the site but not to exceed
* sponsored links from other sites to your
* speed of opening pages
* have links to the Feed
* have a blog (not required)
* set up a sitemap and register it in Google webmaster center
* use the robots file to indicate what to read to the crawlers (spiders) and what not
* date content

In principle you follow these rules, but there are others, you should get good results and ensure a good ranking.
