Movement

This is the first edition on this tier, so no move can be computed for Siteimprove 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 Siteimprove across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“I would recommend Siteimprove if you want the strongest balance of website accessibility monitoring and overall content quality governance in one platform.” Perplexity Sonar · Website governance · paraphrase prompt · first choice

“Often cited as the market leader, Siteimprove is an enterprise-grade platform that combines accessibility, SEO, and content quality into one suite.” GLM 4.7 FlashX · Website governance · comparative prompt · first choice

“Siteimprove is an advanced digital governance platform that combines accessibility, SEO, quality assurance, and analytics in one solution.” Claude Haiku 4.5 · Website governance · comparative prompt · first choice

“Silktide and Siteimprove are frequently cited as leading for teams that want accessibility, content quality and SEO checks in one dashboard.” Muse Glimmer 30B · Website governance · scale prompt · first choice

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.

“Platforms to Avoid if Budget is Very Tight: Siteimprove: ... notoriously expensive.” Qwen 3.7 Flash · Website governance · budget prompt · hard negative

“enterprise website governance and accessibility platforms like Siteimprove, Acquia (formerly Monsido), or Silktide—which routinely start at $5,000 to $50,000+ per year—are usually out of reach” Gemini 3.5 Flash · Website governance · budget prompt · soft negative

“heavily tailored toward large enterprises... custom modular pricing that typically starts at $15,000/year and can quickly balloon to $40,000+” Gemini 3.5 Flash · Website governance · direct prompt · soft negative

“common complaints across the largest platforms (including Siteimprove, Crownpeak, and others) include: Slow performance / slow loading” DeepSeek V4 Flash · Website governance · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Siteimprove. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 179 of the 188 answers that named Siteimprove and are not a share of its labels.

How it is countedHide how it is counted

Every page siteimprove.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. Read September 29, 2026.

Names read as Siteimprove

What the judge wrote, as written, with how often. The vendor table decides that these count as Siteimprove; a claim can dispute any of them.

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 Siteimprove'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 Siteimprove, 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 Siteimprove by email, built from the raw record of the edition. It shows:

where Siteimprove 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 Siteimprove, 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.

Badges

Wins only: a badge exists where Siteimprove is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.

AI models recommend Siteimprove first in Website governance and accessibility this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
