02What they warned about

Sites the answers cite

20 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. 187 links across 85 sites, every framing counted.

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 mobile push notification and SMS marketing platform for a mid-market B2B company?”Paraphrase“Which push and SMS messaging tool would you recommend to a mid-sized B2B company?”Comparative“What are the top mobile push and SMS marketing platforms and how do they differ?”Budget-constrained“What is the best mobile push notification and SMS marketing platform for a company with a limited budget?”Scale-constrained“We are a 500 person company evaluating a mobile push notification and SMS marketing platform.
