I post in multiple categories, so is it better to have:

Consulting > Services > Implementation > Service A

Consulting > Services > Optimization > Service A

Consulting > Services > Upgrade > Service A

or,

Consulting > Services > Implementation, Optimization, Upgrade > Service A

I was doing second way, the problem is google doesn't show 3rd set of crumbs. ie it only displays: Consulting > Services on search result.

But having multiple breadcrumbs on the page doesn't look good. any suugestions?

Update For @PatomaS 's question

I mean 3 lines of breadcrumbs, see above i have posted same article (Service A) in 3 categories (Implementation, Optimization, Upgrade). So you can reach same article through 3 categories. So whats the best breadcrumb to display on article 'Service A'?
