Product analytics

Asked as “product analytics platform”, and as “product analytics tool”, on behalf of a mid-market B2B company. 58 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.

38% of first choices, but two endorsed leaders sit here: Mixpanel is four points behind on share and eleven points cleaner on negatives.

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.

The standing

Share is the count of first choices across the direct, paraphrase, budget and scale prompts, over all twelve models, for a mid-market B2B company. Ordered by share.

Google Analytics 4 is made by Google, whose model Gemini 3.5 Flash is in the set. On the four share prompts that model made it the first choice zero times of 4; the other eleven models one time of 44. Lab treatment is defined on the method page; the row is marked, not excluded.

All fifteen head-to-head pages: the top six products, each against each

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

Seven of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, Grok 4.20, Mistral Small, Llama 4 Maverick and Kimi K2 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.

What they cite

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

Sites the answers cite

73 of 84 answers in this category came back with a source list, from 14 of 12 models: citations where the model returns them, or the search results it consulted. 966 links across 199 sites, every framing counted. Ranked by the number of answers carrying the site or page.

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 product analytics platform”, “product analytics 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.
