In the context of web design, links hold websites together in ways beyond giving visitors a labeled and self-evident method of transitioning between individual pages. Of course, this type of link-building is referred to as internal links because those who would follow them technically both start and remain within the same website. As an SEO concern, the significance of links that are confined within the boundaries of a web domain is that they guide both human users and search engines' web spiders to related URLs within that domain. Since search engines' algorithms attempt to award the highest page ranks to URLs that are evaluated as the most useful and relevant sources for specific audiences, internal links allow spiders to both discover new pages and make associations between the linked pages' respective content.
The companies hosting websites representing their brands also naturally have an interest in links that point to their sites but originate from elsewhere on the Internet. In concept, links pointing toward one website are created on another site because that second website's owner sees value in mentioning the first site as a resource of interest to them and their community. The emergence of these backlinks naturally takes place on its own if a website's content is both strong and relevant to the intended demographic, and the quality of the content the backlinks appear alongside can influence the "link juice" those backlinks funnel to the website in question.
Although recent adjustments to Google's concealed algorithms have downplayed the direct role that backlinks have on a website's ability to rank in the highest positions, websites can still find value in stimulating backlink creation. Writing a blog post on an external site as a guest can be useful for not only the backlink but also the opportunity to establish business ties with established players within the industry. One's own website can also voluntarily host outbound links toward external websites to indicate a willingness to form a positive business relationship with them. Furthermore, Google's spiders can recognize a website's subject matter more clearly based on the high-authority external domains it links to.
