Index Marketing September 2026 Edition

Ecommerce marketing

Asked as “ecommerce marketing platform”, and as “marketing tool for an online store”, on behalf of a mid-market B2B company. 50 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.
Standing
Contested
36% of first choices, contested.

By buyer segment

The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

01The standing

02What they warned about

Two of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, Gemini 3.5 Flash, Perplexity Sonar, Mistral Small, DeepSeek V4 Flash, Llama 4 Maverick, Qwen 3.7 Flash, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. 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
50%
11 of 22 labels negative · 7 of 12 models · 2 hard negative
“Mailchimp\u2019s pricing structures have climbed sharply ... count unsubscribed, cleaned, and archived contacts toward your monthly billing threshold” Gemini 3.5 Flash, negative prompt
Klaviyo

8 of 45 labels negative · 6 of 12 models · 3 hard negative
“Klaviyo — The Most Controversial Right Now ... Trustpilot rating: 1.9/5 ... the worst rating of any major platform researched” DeepSeek V4 Flash, negative prompt
HubSpot Marketing Hub

5 of 34 labels negative · 4 of 12 models · 1 hard negative
“**Avoid Klaviyo and HubSpot Early On**” Gemini 3.5 Flash, budget prompt

“Atrocious/nearly absent account support, chat support that always has to "get back to you later," closing tickets without resolution” DeepSeek V4 Flash, negative prompt

03What they cite

Citations exist only for the models that return a source list: four of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

19 of 72 answers in this category came back with a source list, from 4 of 12 models: citations where the model returns them, or the search results it consulted. 5 of those lists are Google grounding redirects that name no site and are left out of the counts. 199 links across 133 sites, every framing counted. Ranked by the number of answers carrying the site or page. The other 8 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.
