I'm implementing the schemas from schema.org on a site for a services provider.
They sell variations of the same service, customised to different user requirements.
Currently they are have 3 different sign up offers, 3 months, 6 months or a year.
My question is. Should I mark up variation of the service as a product and have the offer nested within that:
> PRODUCT VARIATION
Or should I have the company as a kind of global product, the three offers nested within that and then the products within those:
> GLOBAL PRODUCT
>>> PRODUCT VARIATION
Or does this matter? Will Google/Bing/Yahoo work out this information?
If you require any clarification please just ask.
Thank you for any help.
