Breadcrumbs have been debated quite a bit in the past. Some claim that the last part of the breadcrumb trail should be non-active to inform users they have reached the end. In other words, Do not link the current page to itself.
On the other hand, that portion of the breadcrumb would won't be displayed in the SERPS and if it was may lead to a higher CTR.
Foe example: www.website.com/fans/panasonic-modelnumber
panasonic-modelnumber would not be active as part of the breadcrumb.
What is your take?
