None of the sector's recognised authorities (regulators, trade bodies, leading publications, universities, major partners) link to the site, and few of the site's referring domains are themselves linked from them. TrustRank research shows reputable pages rarely link to spam, so distance from trusted seeds is a spam signal. Google has not confirmed using TrustRank; this check is a proxy for link reputation, consistent with Google's confirmed use of links in ranking.

How do you fix it?
Identify the authorities in the sector and pursue legitimate reasons to be cited by them: memberships, accreditations, research, data, expert contributions and partner listings.
How do you find it on your site?
- List 10 to 20 recognised authorities in the client's sector with the client.
- Check a backlink tool for links from each authority's domain to the site.
- For the site's top referring domains, check whether they are linked from those authorities (one hop away).
- Flag the issue when there are no direct links and few one-hop links, especially where competitors have them.
Which ranking and citation factors does it touch?
Written for the TrustRank page (evidence: General theory). Google has not documented this system in a way a site can test directly, so this check measures a proxy for it, not the system itself.
What is the impact?
Indirect. Estimate only: links from reputable sector sources are likely to strengthen link reputation, but no Google trust score is published.
What is the evidence?
Gyöngyi, Garcia-Molina and Pedersen, Combating Web Spam with TrustRank (VLDB 2004); Matt Cutts on the TrustRank name; Google's ranking systems guide on link analysis.
