Link hoarding is the term given to a website concentrating its efforts on building inbound links while creating no outbound links. This is often done in the belief that inbound links are valuable while outbound links are not. However, this is disputed by some SEO experts, who say that a website’s rank isn’t negatively affected by outbound links.
Furthermore, outbound links are considered to bring value to content, showing that a website’s post has been well researched and that the author or organisation behind posts is well connected to the discourse around their niche. It also provides more value to a reader investigating the topic considered.
