Introduction to Trust in Link Building
Trust is commonly understood to be a standalone quality that is passed between sites regardless of link neighborhood or topical vertical. However, this understanding is outdated and incorrect. What’s important is not the trust that is passed from one site to another, but rather the distance between a site and a trusted seed set within a topic. This changes the way we approach link building and how we evaluate the quality of a link.
What are Link Distance Ranking Algorithms?
Six years ago, the concept of link distance ranking algorithms was introduced. These algorithms create a map of the internet that begins with a group of trusted sites, known as the seed set. The seed set links to other sites, which in turn link to ever-increasing groups of other sites. The sites closer to the original seed set tend to be trustworthy websites, while the sites that are furthest away from the seed set tend to be not trustworthy. Google still counts links as part of the ranking process, and it’s likely that there continues to be a seed set that is considered trustworthy.
The Myth of Trust in Link Building
Trust is not a thing that is passed from one site to another. Sites are said to be trustworthy by the link distance between the site in question and the original seed set. The word Trustworthiness is even a part of the E-E-A-T standard of what constitutes a quality website. So, trust should never be considered as a thing that is passed from one site to another because it does not exist. The takeaway is that link building decisions based on the idea of trust propagated through links are built on an outdated premise.
Why Third Party Authority Metrics Are Inaccurate
The second thing about the link distance ranking algorithms is that websites naturally coalesce around each other according to their topics. Some topics are highly linked, and some are not well linked at all. The consequence is that those poorly linked sites that are nevertheless close to the original seed set do not acquire much “link equity” because their link neighborhoods are so small. Third-party link metrics that measure how many inbound links a site has fail because they follow the old and outdated PageRank scoring method. The seed set paradigm does not measure inbound links; it measures the distance from sites that are judged to be trustworthy.
The Importance of Link Neighborhoods
Websites tend to naturally link to other sites that are on the same topic. The seed sets can be chosen according to topic verticals. Some verticals have a lot of inbound links, and some verticals are in their own little corner of the internet and aren’t linked to from outside of their clique. A link distance ranking algorithm can thus be used to calculate the relevance according to whatever neighborhood a site is located in. The point is that there is no context for thinking about trustworthiness as something that spreads from link to link.
Key Takeaways
The following are the key takeaways from this article:
- It is counterproductive to go after so-called “high trust” links from verticals that are well outside of the topic of the website you’re trying to get a link to.
- This means that it’s more important to get links from sites that are in the right topic or from a context that exactly matches the topic, from a website that’s in an adjacent topical category.
- A site like The Washington Post is not a part of the Credit Repair niche. Any “trust” that may be calculated from a New York Times link to a Credit Repair site will likely be dampened to zero.
Takeaways
- Trust is not something that’s passed by links: Link distance ranking algorithms do not deal with “trust.” They only measure how close a site is to a trusted seed set within a topic.
- Link distance matters more than link volume: Ranking systems based on link distance assess proximity to trusted seed sites, not how many inbound links a site has.
- Topic-based link neighborhoods shape relevance: Websites naturally cluster by topic, and link value is likely evaluated within those topical clusters rather than across the entire web.
- Third-party authority metrics are misaligned with modern link ranking systems: Some third-party metrics rely on outdated Page Rank-style link counting and fail to account for seed set distance and topical context.
- Low-link verticals are undervalued by SEOs: Entire niches that are lightly linked can still sit close to trusted seed sets, yet appear weak in third-party metrics, causing them to be overlooked in link builders.
- Relevance outweighs perceived link strength: Links from well-known but topically irrelevant sites likely contribute little or nothing compared to links from closely related or adjacent topic sites.
Conclusion
Modern link evaluation is about topical proximity, not “trust” or raw link counts. Search systems measure how close a site is to trusted seed sites within its own topic neighborhood, which means relevant links from smaller, niche sites can matter more than links from famous but unrelated domains. This knowledge should enable smarter link building by focusing efforts on contextually relevant websites that may actually strengthen relevance and rankings, instead of chasing outdated link authority scores that no longer reflect how search works. By understanding the importance of link neighborhoods and the myth of trust in link building, we can create a more effective link building strategy that drives real results.
