The positioning of a resource (and therefore its visibility) in the results organic is the result of a content that meets looking for someone and is considered by his party as a reference on his specialty.
Therefore: identify that seek Internet users and the keywords they use, adapt its editorial to the lexicon used by Internet users and thus to set the content of a website or blog according to users needs/research and write intelligently the URL of that content, to efficiently transfer (HTTP) and properly format (HTML) information.
The visibility of a document will be so natural and depends directly on the provided content. Indeed, quality content is often referenced by other sites: content, popular due or considered the reference in its sector, will be well positioned as such (for example the reference will always be in the first position) in the organic results.
A few criteria for positioning of a web page on a given expression
There are many hundreds of parameters used by the algorithms of positioning, here is a list of the most important commonly accepted:
The popularity of the page, the relevance of the binding section, the text of incoming links, the relevance of the page, page confidence index, the seniority of the portal, the authority of the name of area, PR (Page Rank) of the page, presence in local directories
All these criteria are there to provide in-fine the Internet user to pages relevant and particularly taken on the subject.
The recursive aspect of algorithms on many major criteria such as popularity or the confidence index makes it difficult to all results manipulations.
It is to further clarify that the current priority is to fight spam, the algorithm shall therefore ensure that the popularity of positioned article was acquired in a natural way.
Thus, a web site at the same time contracting an inordinate variety of link will be sanctioned by the algorithm.
