Optimal SEO of your website in Google Search (SEO)

The advent of digital technologies and the Internet in France is growing rapidly each year. The impact of this phenomenon on the trade is undeniable since today more and more companies are transferring part of their trade on the Internet. It is important for a company not to neglect the impact of the web since we are 83% to use internet in France. We use the web every day to:
find a company that provides the services or products we are looking for
learn about the seriousness of a business
In France in 2014 the rate of equipment of French companies with a website is 65%. The first observation is that if you are part of the 35% of companies that do not have a website you leave the place to your competitors. If you are one of the 65% to have your website then you find yourself in direct competition with your usual competitors. Because it is about this: being present on the Internet is essential, being well positioned in the Google results is just as much. The competition is tough, you must act or you will fall into the abyss of SEO.
What is SEO SEO?
First of all we will only talk about Google which today represents in 2015 a market share of 96% in web searches. SEO is to position yourself in the results of Google on searched expressions.
We can not talk about a position if we do not speak of expression. For example, "I am (badly) placed in Google" does not make sense. "I'm (badly) positioned in Google on -plombier six fours-" is much more relevant. "Natural" referencing consists of taking actions to improve one's position on one or more expressions. This is therefore measurable: on a date D1 I have the position N1 on the expression E, on a date D2 I have the position N2 on the expression E It is thus possible to measure the evolution (in addition or in less) of your position on this or that expression.
