Welcome to the Q&A Forum

Whether you look at zappos.com, bol.com, or other e-commerce websites you will almost always see a footer that is full of links to categories & subcategories. These elements aren't really attractive, and to be honest, I don't think I ever clicked on one of those links because most of the time I don't reach the bottom of such pages. Why do these companies use these kinds of footers? Is it for SEO purpose,? Are those links passing juice? Aren't those links at the bottom of the page and therefore not that relevant as other links used in paragraphs? Aren't they contributing to too many on-page links? Maybe only use it on homepage? I'm really looking forward to the opinions of the experts here at the forum...
