The Off-Page Authority Triangle: Reviews, PR, and Mentions
LLMs corroborate. Three off-page signals — reviews, PR, and unlinked mentions — form the triangle that decides whether an engine trusts your brand.

On-page work makes your content extractable. Off-page work makes the engine trust it. Three off-page signals form a triangle that, taken together, decides whether an answer engine treats your brand as a credible source: reviews, PR, and unlinked mentions.
Side one: Reviews
Review platforms — G2, industry-specific directories, Google — are corpora that answer engines read. A brand with consistent, substantive reviews on the platforms an engine trusts is corroborated as real and credible. Perplexity in particular leans on review sites.
Side two: PR
Press coverage in publications an engine already cites does two things: it provides a trusted third-party description of the brand, and it associates the brand with the topic in the model's view of the world. PR is not vanity here — it is entity corroboration.
Side three: Unlinked mentions and co-citation
Co-citation is being mentioned alongside a topic and alongside authoritative sources, even with no hyperlink. For LLMs this matters because training and retrieval build associations between entities from text proximity, not just links. A brand named in the same paragraph as the topic and a trusted source is being taught to the model.
Before
A client had solid PR and mentions but almost no reviews. Engines mentioned the brand but rarely as a recommended option.
After
After a focused review-generation push on two platforms, the brand started appearing in 'best of' style answers.
Takeaway
Engines were waiting for the third side of the triangle. Diagnose which side is missing before you spend.
How an agency operationalizes the triangle
- Audit all three sides for the client and score which is weakest.
- Invest first in the weakest side — that is where the marginal citation is cheapest.
- Re-measure citation share monthly and rebalance.
