Welcome to the Q&A Forum

Even if you look at the home page and the nav menu will have the word "windsurfing" in front of each menu item?

Thanks for the response. I did that off course and I am scoring an A grade on the on-page optimastion side. That says nothing about how the users will view it and if a human review of google will flag it as spammy.

I would like to rank for words as:
windsurfing equipment
windsurfing news
windsurfing sails
windsurfing boards etc.

Now am I wondering if I should use exact those words in the navigation/titles/descriptions because it seems not user friendly. The whole website is about windsurfing thus naming it just “equipement” instead of “windsurfing equipment” would be clear to a visitor that I am talking about that windsurfing related topic.

Here is an example: http://madwindsurfing.com/cat/competitions-events/
I can even change the URL to http://madwindsurfing.com/cat/windsurfing-competitions-events/

What would be the best way of choosing the naming/descriptions when I do on-page optimisation which is good for the engines and for the users and who would you do in my case?
