High-weight backlinks generally refer to those that have a relatively high trust value in the eyes of search engines such as Google. The content published on such websites may be quickly captured and indexed by these search engines and participate in the ranking process. If an article with backlinks is published on such a website, the backlink will also be crawled by the search engines and even be quickly indexed. In the eyes of the search engines, this high-weight website has given you a vote of trust with its backlink, while low-weight links do not have such an advantage.
