Your current observations show that:
Given the nature of your site, 99% of the pages will likely never be shared, so the sharing widget that shows "0 likes, 0 tweets, etc" becomes a monument to how unshared (and unsharable?) your content is.
I have experienced this exact same scenario with a large B2B site I managed.
There are two places that might warrant the inclusion of a sharing widget:
- The Homepage - assuming you have a convenient location on the page. This gives the rare user who wants to share somewhere to share from, and keeps the marketing department happy.
- Pages that perform well in organic search - if product pages do well from an SEO perspective, it those pages are objectively valuable (assuming your SEO practices are actually organic and white-hat), so if any pages on your site are worth sharing, and therefore worth having a sharing widget, it's these.
Otherwise, save the space and cut down the visual distraction by leaving this UI element out.
