Problem referencing of worpress articles

Hello,

I created a Web site there is a few weeks:

http://tourbilol.com/

The site was well referenced (2nd page on Google when we return ” tourbilol “)

My problem it is because when we bang(type): “site:tourbilol.com” on Google to see all the pages referenced on Google.

I realized that only pages were referenced (all the present big parts(parties) on the navigation bar) but articles (which are contained in the categories of the navigation bar) are not referenced.

I do not know how it is and how seen to it to reference articles.

I installed(settled) a plugin of SEO on wordpress which presents exactly the referencing of the article, but it does not work:
