Protocol

By Aurélien Bardon

In order to make the reading of this guide as digestible and pleasant as possible, I have not systematically included all the protocols followed. Indeed, since most of the tests follow the same process, this would have been of little interest.

The idea is to always use a keyword that does not exist (not provided in the French dictionary) and that does not return any result page on Google and Bing.

So if after having implemented this keyword on the analyzed criterion and the test web page is ranked, we

can then legitimately think that the algorithms of the search engines are sensible to the tested criteria.

We will then speak of validated and non-validated criteria.

You will find in the tests that will follow the following icons:

Icons	Meaning
	The test does not permit giving an opinion about the validity of the criterion evaluated.
	The criterion tested seems non-valid.
	The criterion tested seems non-valid.
