Regarding Google's rich snippets for product markup...
I have a site with various widgets on it and would like to use the product markup. I am confused as to how to go about this though. Each widget has its own features page with basically all the details needed for the markup, but is it okay to basically markup the whole page since the various details are all throughout it and then just do this for each widget page?
Or... I have a description page which has a brief 'intro' of all the widgets on it together for people to read over and select from... would it be better to use this and do all of them on one page?
Do I need to markup the products on every page they appear on the site or only once on the site?
I could not find any details on the correct way to go about this other than they tell you how to mark them up... well is it every page or only once?
