Hilltop Algorithm

The Hilltop Algorithm, acquired by Google in 2003, was a highly influential, early algorithmic update that fundamentally shifted how search engines evaluated backlinks. Hilltop introduced the concept of “expert” documents-pages that specifically linked to a large number of highly relevant, non-affiliated websites on a specific topic (like a massive directory or resource page). The algorithm dictated that a link from one of these recognized “expert” hubs carried significantly more weight than a standard link. Hilltop established the foundation of modern topical authority and the extreme value of securing links from highly curated, industry-specific resource pages.

The Hilltop Algorithm was an early Google update that made some links much more powerful than others. It decided that if a massive, highly respected directory of websites linked to you, that link was worth ten times more than a random link from a normal blog.
