I took a look at your blog from another post of yours (fascinating stuff, based on what I can tell from Google Translate, at least). Any chance you were secretly penalized because of some of the more risqué content on your site?

I can be wrong but it seems the contrary. 80% of our traffic is generated by the alternative content. Maybe it lowers the ranking of the Python content. Hard to say.

But now we are actually quite famous in the french Python community. For a blog on such a niche topic in a small country we get around 6000 v/d. The hard part was starting really: we (my co-author and I) have no promotion skill whatsoever.

We actually starting to gain traction after 3 major french bloggers linked to us completely out of the blue (sebsauvage, korben and lehollandaisvolant). It seems linking from trusted source is still the most important part of the game for google.

Eventually I want to create a new site, in english this time, to translate all the stuff and make it SFW so it can benefit more people. Unfortunately this won't be enough to test your theory since as soon as you create content in english, you multiply you traffic by 10000.

Anyway first I'll need to save for 5/6 months of budget before doing so cause as a freelancer I can't really take holidays. Maybe I should do a crowd founding.

Off topic... but thank you for your great blog. :)

:) It's always nice to support, even after all these years. It's a hard job, and we don't get paid to do it so we need to hear comments like that.
