Movement

This is the first edition on this tier, so no move can be computed for Similarweb yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Similarweb across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Best Overall Budget Pick: Similarweb ... Widely regarded as the best market intelligence platform for its price.” DeepSeek V4 Flash · Market intelligence · budget prompt · first choice
“Start with Similarweb's free data” GPT-6 Luna · Market intelligence · budget prompt · first choice
“If the company is looking for a platform that can provide comprehensive digital intelligence... Similarweb may be a good choice.” Llama 4 Maverick · Competitive intel · paraphrase prompt · alternative
“their free browser extension and basic web platform provide valuable high-level data on competitor traffic sources for free” Gemini 3.5 Flash · Market intelligence · budget prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Do not use this as your sole source of truth for competitor traffic... otherwise, avoid or cross-validate everything.” DeepSeek V4 Flash · Competitive intel · negative prompt · hard negative
“Verdict: Avoid for critical business decisions. Use only for rough market sizing or trend spotting.” GLM 4.7 FlashX · Competitive intel · negative prompt · hard negative
“Similarweb is described as not useful for day-to-day optimization because it cannot help you optimize pages, track rankings, or audit technical issues” Perplexity Sonar · SEO · negative prompt · soft negative
“I would be cautious about using these as authoritative sources: - Similarweb and Semrush for exact competitor traffic, revenue, or market share.” GPT-6 Luna · Market intelligence · negative prompt · soft negative

Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

How it is countedHide how it is counted

Every page similarweb.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Similarweb's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Similarweb, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Similarweb by email, built from the raw record of the edition. It shows:

  • where Similarweb is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name Similarweb, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at similarweb.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
