The floor is 12 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one can't be told apart from repeat variation, and both are shown. Each index measures its own floor from its own repeat, over its own categories, so the floor differs from one index to the next. How the floor is measured

Bars are the share of first choices, 0 to 100Every product with at least 10 labels here. Every product name links to its product page.

Recommended versus criticized

Every product with at least 10 labels here, on both axes. The 30% line names a quadrant, not the verdict above: that one needs more than 40%.

What they warned about

Six of six models held their first choice under the paraphrase. 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.
Mailchimp
62%
8 of 13 labels negative · 6 of 6 models
“Mailchimp is the standard cautionary tale here — price hikes and restrictive contact and email limits have pushed customers to alternatives” Claude Opus 5, negative prompt
Attentive
50%
4 of 8 labels negative · 4 of 6 models
“Some discounted agreements include minimum spending commitments. If usage falls short, you’re invoiced for the remaining commitment.” GPT-6 Astra, negative prompt
HubSpot Marketing Hub
22%
4 of 18 labels negative · 4 of 6 models
“Exceeding your marketing-contact limit triggers an automatic tier upgrade... prohibits mid-contract cancellation or downgrades.” GPT-6 Astra, negative prompt
Klaviyo
27%
7 of 26 labels negative · 4 of 6 models
“As of February 2025, Klaviyo bills on total active profiles, meaning every contactable profile counts whether you email them or not.” Claude Opus 5, negative prompt

What they cite

Six of the six models returned a source list in this edition: six return the pages they cited.

Sites the answers cite

28 of 36 answers in this category came back with a source list, from 6 of 6 models: citations where the model returns them, or the search results it consulted. 426 links across 230 sites, every framing counted. Ranked by the number of answers carrying the site or page. None of the 36 answers across every segment cited this index's own page for the category.

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.

Search against answers

Each company's standing in the answers beside its site's footprint in Google search, one row a site: the products the models named on it with their shares, and the share they add up to; monthly searches on Google, and DataForSEO's estimate of AI search demand (modeled from search signals, directional, not a count of queries to any assistant), for the most-searched of the company's and its products' names (the name is in each row's hover text); estimated monthly organic visits to the site; and its best position in Google's top ten for “best ecommerce marketing platform”, “ecommerce marketing platform”. US estimates from DataForSEO and Google's Ads Transparency Center. A small company's site, or a mid-sized company's site for its flagship, is marked company; a product on a large parent's site (Google, Microsoft) has no site figures. A column with no figures for this category is left out, and an empty cell means none were seen, not none exist. Two measurements side by side: neither is read as the cause of the other.

How 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.
