Here is why this is critical: ### 1. Links are like recommendations If other sites, especially authoritative ones, link to a page, this is perceived as a "vote of trust". In essence: > "If others consider this content valuable, it probably deserves attention". ### 2. Popularity signals Mentions in the media, blogs, forums, and social networks are markers that a site generates interest. Algorithms see that the content lives beyond the page itself, which means it is relevant and active. ### 3. Harder to fake On-page optimization can be "drawn up". External signals, however, are harder to control. That is why they are considered a more "honest" indicator of a site's value in the eyes of others. ### 4. Separating quality Millions of sites write the same thing. But some have 5 links, others have 500. This helps the search engine rank pages by authority, not just by content. Put simply, external signals are a site's social rating. And the search engine trusts it more than the site's own self-assessment.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
