Is it useful for SEO to cross link between TOP level categories, let's say I have a Home page and then 2 sub categories, one about green widgets one about red widgets
Should i create a link from the green widget to the red widget or should I leave those are separate silos ?
I know that within a silo i need to cross link ( from green widget 1 to green widget 2 etc... ) but how about about from the main category to the other main category ?
