Internal links are exactly what the name suggests: hyperlinks from one page to another within the same website. These are vital to helping visitors navigate through your website.
By offering visitors plenty of quick, easy internal links within your website, you help usher them through your website and can even move them in the direction you want.
A good example of effective internal links is in the main drop-down menu of a clothing shop’s website. This will typically include links to all the different brands, categories, genders, etc. in one clear layout so that a customer can quickly find what they’re looking for and get to the page in a minimal number of clicks.
