I have a maths related site and google created the sitelinks for my site , :) :) google is giving my site some priority
and i'm using the google web master tools
And there is an option to block any unwanted links from that list...
But the sitelinks are not exactly the subcategories of my site.
Can we decide what should be our sitelinks in google?
Note: I tried to create a new tag as 'google-sitelinks' but without reputation i could not create such one.
