Internal linking on a website involves linking between different posts within content pillars, which are groups of posts centered around a specific set of keywords. Each content pillar has a main post focused on a main keyword, with related keywords being explored in other posts within the same pillar. It is important to keep related posts within the same content pillar and not link between different pillars. Linking to and from a 404 error page as if it were an index page may disrupt the structure of content pillars.
Linking to a 404 error page from within your content pillars can disrupt the intended flow of your website. It can confuse search engines and users, impacting your search engine optimization (SEO) and user experience. Instead of linking to a 404 page, it is best to redirect users to a relevant page within the same content pillar or to a general landing page. This ensures a seamless browsing experience and maintains the integrity of your website’s structure.
