I generally use the back button if I want to go back or click the logo to hit the homepage again. I rarely use breadcrumbs but my employer found a year back that adding breadcrumbs to the website boosted SEO significantly. I'm wondering if this is because the early URL with SEO relevant text in the scope of the content or if people are actually clicking them.. Any thoughts?

The SEO advantage is unknown to me (and off-topic), but breadcrumbs are a good thing. Even if the user doesn't actually click on them, it is a visual reference to where they are. It helps them develop a mental model of how your site is laid out, and thus aids them in navigation indirectly, even if they don't click the links right in the breadcrumbs. Jacob Neilson speaks highly of breadcrumbs.
