High pr doc files

[seo.academy]

I saw that the website www.comunicatedepresa.net outranks www.comunicatedepresa.ro for the therm "comunicate de presa" in google.ro SERP even though .ro beats .net in every seo indicator (links, domains linking, fb likes, g+, onpage etc)

I saw that site:www.comunicatedepresa.net returns a lot of *.doc files with a title that contains the kw ("comunicate de presa").

Ex:

www.comunicatedepresa.net/worddoc/1485/

It seems a little suspicios to me.Did anyone see this before (google giving higher importance to doc files)?

Does anyone know why .net site is ranking better?

I love these questions because they defy the laws of Google gravity!  There are many "indicators" outside of the commonly discussed you find most often in these forums.  You are on the right track in suspecting that Google takes the format of a site's content into consideration.  If a site has relevant textual content along with a variety of downloadable .doc or .pdf files with relevant titles, preference may be swayed toward the site that seems to offer the most relevant information.  Variety does matter, whether you're offering content that's supported by images, videos, outbound links, .doc documents, or .pdf documents, etc.

I also suspect that .net extension carries more weight than .ro, but there's no conclusive evidence that I can find.
