So the first thing to do when analyzing how usable a site is should be to make sure people are able to easily find their way around no matter which page they first landed on. When it comes to huge websites, breadcrumbs can be a great way to help users identify where they are located.

Breadcrumbs are an excellent way to improve the internal backlinking and on-page SEO of a website. However, for a smaller website (like this one) there might not be a real need. It's always important to balance usability with search engine optimization.

For websites operating on the wordpress platform, there are good breadcrumb plugins available to magically create breadcrumb type navigation for your website.
