The short answer

In 2016 Google's Andrey Lipattsev described backlinks as one of the top three Google Search ranking factors, but by September 2023 Google's Gary Illyes said backlinks are important, people overestimate their importance, and they have not been in the top three for some time; a 2024 Search Engine Roundtable report quoted Illyes as saying Google needs very few links to rank pages and has made links less important over the years. Google's current documentation positions backlinks as one quality factor among many: the How Search Works page says whether other prominent websites link or refer to content is a quality factor, the SEO Starter Guide says PageRank is just one of many ranking signals, and the ranking systems guide says PageRank continues to be part of Google's core ranking systems. Google's Webmaster Guidelines introduced a Link spam section as of 2022-10-13, and its spam policies state that buying and selling backlinks is not a violation as long as the links are qualified with rel="nofollow" or rel="sponsored"; however, a pattern of unnatural, artificial, deceptive, or manipulative backlinks can result in a manual action, the disavow tool is an advanced feature that should be used with caution and can harm performance if used incorrectly, and most sites will not need it because in most cases Google can assess which links to trust and works very hard to ensure third-party-site actions do not negatively affect a website. A 2025 Backlinko analysis of 11.8 million Google results found the #1 result has on average 3.8 times more backlinks than positions #2 through #10; a 2025 Ahrefs study of 75,000 brands found a backlink correlation of 0.218 with AI Overview brand visibility, compared with 0.664 for web mentions, and states all factors it studied revealed moderate to very weak correlations; a 2026 Search Engine Land article reports typical link building pricing sheets show flat rates of $400 to $500 per backlink or rigid monthly retainers starting at $5,000, based on the author's audits of vendor proposals.

Often said, but we could not find it in the rules4

Lots of people say this. We went looking for an official source that backs it up and could not find one, so treat it as something people repeat rather than something settled.
