Answer : these values are collected strictly thanks to
the use of the
Alexa bar...; which is apparently very little used at least in France.
Hence possibly messing up the statistics. It might well be the same for
other languages, in particular those for which the Alexa bar... is
simply not working/translated. So... be careful with the use of the
Alexa data. They are a very interesting feedback... but also to take
with a pinch of salt.
It's the same in Poland - I think very few Poles use Alexa bar.
