Tangram

Tangram evaluates nothing itself — it is the assembly layer that takes the ratings from NavBoost and Glue and builds the final search results page from them. Think of it as a conductor: it decides which elements appear where on the results page, but it doesn't judge whether the content is good.

The outputs of NavBoost and Glue as input — Tangram combines these behavioral ratings into a SERP layout, making no judgments of its own.

GlueResponse = the behavioral input delivered by Glue, which Tangram assembles into the final SERP layout; Tangram itself is the composition layer, not a measured value. [B/C]

Tangram has no direct E-E-A-T bearing because it doesn't judge. Authority and Trust appear only indirectly because Tangram arranges the results of systems that do measure those dimensions.

There is no direct lever at Tangram. Whoever optimizes NavBoost and Glue through genuine user satisfaction automatically benefits — Tangram then shows the content in the right place in the right order.
