02What they warned about

A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.

Citations exist only for the models that return a source list: four of the six in this edition.

Sites the answers cite

18 of 72 answers in this category came back with a source list, from 4 of 6 models: citations where the model returns them, or the search results it consulted. 6 of those lists are Google grounding redirects that name no site and are left out of the counts. 161 links across 87 sites, every framing counted. Ranked by the number of answers carrying the site or page. The other 2 models searched through a gateway that returned no source list on this edition.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best customer data platform for a mid-market B2B company?”Paraphrase“Which CDP would you recommend to a mid-sized B2B company?”Comparative“What are the top customer data platforms and how do they differ?”Budget-constrained“What is the best customer data platform for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating a customer data platform.

Noise floor in this category

Flips between the edition run and its calibration repeat. Six prompts per model is a small sample; the index-wide floor is the number to trust.
