What is the importance of the population density

Keywords on a web page?

Since the beginning of the web, specialists of the references
I've always wanted to be able to define the ideal percentage
For the number of times, a keyword must appear in
A web page to optimize its classification in the
The search engines. Not only is this ideal parameter
There is no (otherwise it is not possible), but in more each
Engine applies its own algorithms, which, in addition,
Change very regularly.

The population density corresponds to the number of times a keyword is
Repeated in the total number of words in a particular page.

For example, if a page of 200 words includes ten times the
The word "optimization", the density of the word is of 5%. The myth
This page wants to be better than another whose classifieds
A density of the same word is only 2%. In general, it is
He admitted that a density between 5% and 10% would be the
More effective. Around 20% and beyond, there are risks
That search engines for the Prohibition of the pages
The cause of the attempt to "spam".

Some tools of analysis of density will take into account the
By including the words on the labels "title", "meta tags" and "Meta
Description" while others do the calculation on the text
Alone.

This could be as simple, yet.

The algorithms of the motors have a functioning
Much more complex. Its objective is the reason
More possible with the criteria "human" in order to provide them
The most relevant results. An engine gives weight to
The location of the words on the page and to the nearby
Between them. It analyzes the quality, especially
