Did you know that Google uses something called “PageRank Nearest Seed”?
This means there are authoritative, highly trusted websites that Google refers to as “seed websites.”
Your link’s value is calculated based on its distance from these seed websites. For example, if you get a link from a seed website, it is a powerful link.
If you get a link from a website that got a link from a seed website, it is less powerful, and so on. The further your link is from a seed website, the less power it holds.
