I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc.
I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase.
The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos.
So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
