About a year ago, Mike Blumenthal covered how Google added a product and services link to edit what people see in your local knowledge panel around the products and services you sell. Most people did not see it but it seems to be rolling out to more businesses now, a year later.
Personally, I do not see it for any of the businesses I control under Google My Business, but others are seeing it.
Kevin Getch posted a screen shot on Twitter of it in action:
Mike responded saying it is likely category dependent:
My experience was that it was category dependent.

But Ben Fisher doesn't agree:
Does not seem to be category dependent it does seem as if it is not 100% roll out I have it in some accounts and not in others

In any event, do you see this option in your Google My Business account?
