Breadcrumbs are a trail of website links that allow visitors to track where they are on a website and how far they are from the home page. Usually, they are visible at the top of a website or just under the navigation bar. Even Google uses breadcrumb-style navigation in the SERPs. Breadcrumbs are incredibly SEO-friendly; they add internal links to your site, improve your site architecture, and encourage people to visit more pages on your website. Usually, web designers prefer not to add breadcrumbs to the site as they think breadcrumbs disrupt the page design. However, well-placed breadcrumbs can do much more good than harm. You should add breadcrumbs to your website where they are visible to the users. Also, breadcrumbs should be mobile-friendly. If they are visible on mobile devices, you should make sure they are big enough or button-like to be clickable.
