The difference between a relative link and an absolute link is relative links are much shorter while absolute links always contains the full address of a page. I have relative links to different pages on my website but an absolute link like to to Zelda Wiki is outside my website so it contains the full address. That is important because it affects navigation on a website it is important to have good navigation so that you get more people going onto your website, having a navigation bar helps to make navigation easy for the viewers because they don’t have access to the pages like the creator of the website has. Navigation is important for organization of the website.
