Definition
Entity SEO treats expertise, experience, and trust as attributes of a person or an organization – an entity – rather than attributes of a single page.
That distinction sounds academic until you watch it decide who gets cited. A model choosing a source does not read your site the way a visitor does. It checks whether a consistent, verifiable identity exists across the places it already trusts, and it does that before it evaluates a word of your writing.
A page can be optimized. An entity has to be built.
Two ideas come out of that work. I named both because I needed to point at them in client conversations, and pointing at something unnamed is slow.
Trust Halo
Trust Halo is the name I use for the transfer of an established entity’s trust to a new domain connected to it. When the search ecosystem already knows who stands behind a project, a brand-new site can inherit credibility it has not earned on its own. I did not plan mine. I noticed it, three weeks in, while trying to work out what was wrong with my analytics.
In February 2026 I launched madera-online.pl with just over a dozen articles and no backlinks. By March it had reached roughly 4,000 clicks.
Then the part I had not planned for. On 20 March 2026, weeks after launch, two national outlets cited the site as a source on closed hiking trails in Madeira: Dzień Dobry TVN, quoting me by name, and Podróże Wprost, which MSN then syndicated.
It was not the first time either. In September 2025, Interia Hub sourced a piece to bornholm-online.pl, another small blog of mine with no press office behind it. Twice, on two unrelated domains, in two different fields. At that point it stops looking like luck.
The explanation was not the domain. Google and several language models already had enough signals to connect each project with me – and a journalist checking who was behind it found a person, not a blank.
The full case study, with the search console data, is in my 2026 book – published in Polish.
Authority triangulation
Authority triangulation means establishing three separate kinds of authority, so that credibility does not rest on a single source. One kind alone is fragile: an impressive client list means little to a journalist, and a well-cited paper means little to a procurement team. Three, all pointing at the same person, are hard to wave away.
Institutional
Recognition granted by bodies that answer to their own rules – a university lectureship, a publishing house, a library authority record.
Market
Evidence that people pay for the work and come back: named clients, repeat engagements, conference invitations that were not bought.
Substantive
The work itself, checkable by anyone who cares to check – books, published research, documented case studies, the E-E-A-T signals a search engine can actually read.
