Radar Assessed 50 Known Brands for AI Readiness. Scores Ran From 4 to 88.

What the Data Says

The Radar Brand Index tracks 50 recognizable brands across SaaS, E-commerce, Fintech, Healthcare, and Media. Each one is scored with Radar's AI Readiness Score, a technical check of the brand's own site. Full results are public, re-scanned on a rolling schedule, and free to browse.

Correction: an earlier version of this post said each brand is audited weekly with Radar's full 13-tool methodology, including live AI queries, and described blocked and low-scoring brands as invisible to AI. As of 24 September 2026, this version replaces it: the index uses the AI Readiness Score only, brands are re-scanned on a rolling schedule, its launch grades used the index's own cut-offs (C from 55, D from 40), and a low score or a blocked scan does not show that AI engines cannot read or cite a brand. It also reported that 56% of brands scored D or F. With a median of 55 across 47 scored brands and D starting below 55 at launch, at most 26 of the 50 brands could have been D, F or blocked, so that figure cannot be right, and the launch scores were not kept to recount it. This version no longer uses it.

The headline finding is uncomfortable. At launch, the average score across the 47 brands that returned a meaningful audit was 54.6 out of 100, and the median was 55. Three additional brands returned no useful data at all because of paywalls or anti-bot defenses, and we mark those Audit Blocked instead of forcing a zero score.

Some of the brands in this lower half are names you would expect to be on top of AI search. Patagonia is one of the most beloved content brands of the last decade. Substack hosts thousands of writers. Stratechery is the gold standard for technology newsletters. The New York Times is The New York Times. None of them scored above a C grade in the index at launch.

This piece walks through the findings. It is not a takedown of the brands that scored low. It is a snapshot of what Radar's technical checks found on these sites in May 2026. Most teams have not adapted to the technical demands of AI ingestion. The few that have show what is possible, often without the budget or recognition that suggests they should be ahead.

How the Index Works

The index uses one score from Radar's audit pipeline: the AI Readiness Score, which checks AI bot access, structured data, llms.txt, content accessibility and cross-signal consistency on each brand's site. The score comes from those technical checks, not from AI answers. The scoring formula is published at /platform/methodology.

The catalog is curated, not algorithmic. Ten brands per category were chosen for global recognition, public AI/SEO presence, and a mix of leaders and challengers within each vertical. The list is not a ranking of importance. It is a sample of names readers will know.

“The bar for AI readiness is technical, not creative. Beautiful content still needs a page that machines can parse.”

Radar Brand Index, May 2026

When a brand returns no useful audit data because of a paywall, a login wall, or aggressive anti-bot defenses, we mark it Audit Blocked rather than scoring zero. This is a real and important signal. A score of zero implies the content is bad. Audit Blocked means the Radar scan could not read the content, regardless of its quality. Three brands in the index (Chime, Quartz, The Information) are in this state. We will return to them later.

The Top of the Index

Six brands earned an A grade. Three of them are SaaS companies. Two are healthcare or fintech. One is consumer e-commerce. The pattern is striking, and the lesson is structural.

Stripe and BetterUp tie at 88. Stripe is unsurprising. The company has invested heavily in technical SEO and developer documentation for years, and most of the AI visibility infrastructure (clean robots.txt, well-formed schema, rich llms.txt-equivalent documentation) was already in place before AI search was a category. BetterUp is more interesting. The coaching platform has built a content library that is technically accessible by AI in ways that most healthcare brands have not.

Webflow and Casper share third at 87. Webflow is again expected. The platform is built by people who understand machine-readable structure. Casper is the surprise. A mattress DTC company outscoring most healthcare and media brands is not what category-bias predicts. Casper has historically invested in long-form content marketing (the now-defunct Van Winkle's, sleep journalism), and the technical residue of that investment shows.

Calendly and Asana close out the A grades at 86 and 85 respectively. Both are pure-play SaaS companies, both have engineering-led product teams, both have well-structured docs and marketing sites.

The pattern: technical investment in machine readability beats brand recognition. Companies that built their websites for developers and search engines are the same companies that AI search can read.

The Surprising Bottom

The bottom of the index is the part of the data most people will find uncomfortable. These are not unknown brands or failing companies. They are recognized names that struggle with the specific technical demands of AI search.

Patagonia scored 35 out of 100, a D grade. Patagonia is one of the most respected content brands in retail. Their long-form journalism, environmental reporting, and product storytelling won industry awards for years. The score reflects technical infrastructure, not creative quality. The readiness checks found a JavaScript-heavy site structure and incomplete schema markup. The story is the same for Warby Parker (32, D), another DTC darling whose creative voice did not show up in the readiness checks.

Substack scored 42, a D. The platform that hosts thousands of independent writers has not optimized its own brand site for AI visibility. The publication infrastructure for Substack writers is one thing. The pixelmojo.io equivalent of Substack as a brand is another, and that brand site shows an irony that will not be lost on any of their writers.

Stratechery scored 39, a D. Ben Thompson's newsletter is one of the most-cited tech publications in the industry. The brand site itself ranks lower than its content suggests because of paywall mechanics that block much of the writing from being crawled directly.

The New York Times scored 41, also a D. The flagship of American journalism. Same pattern: paywalls, JavaScript rendering, and a schema implementation that has not kept up with AI search expectations.

The most striking result is in healthcare. Hims and Hers, the DTC men and women health brands, both scored 4 out of 100. Both companies are publicly traded and have significant brand recognition. The score reflects an aggressive sign-up wall, JavaScript-only rendering of all clinical content, and a robots.txt configuration that blocks most non-browser user agents. The site looks healthy to a human visitor; the readiness checks found almost nothing they could parse.

This is not a moral judgment of these brands. The decisions that produced these scores (paywalls, sign-up walls, anti-bot defenses) were rational responses to other business problems (content theft, scraping, conversion optimization). They are also the decisions that lower a brand's AI readiness score.

Healthcare Is the Worst Category

The category averages tell a story.

SaaS leads at 66.9 average. Engineering-led product teams build technically readable sites by default. The same disciplines that produced clean APIs and developer documentation now produce clean schema markup and robots.txt configurations.

E-commerce comes in second at 61.2. DTC brands have spent the last decade investing in performance marketing and SEO, and the residue helps with AI visibility too. Casper, Allbirds, and Glossier all scored above the index average.

Fintech sits at 57.8, helped enormously by Stripe at 88 and dragged down by Revolut at 28. The variance is large within the category. Modern banking interfaces tend to be JavaScript-heavy and gated, both of which work against AI crawlers.

Media at 47.3 is the surprise. The category that should be most content-rich is, on average, second worst. The reason is paywalls. Most major media brands have spent the last five years tightening paywalls in response to ad revenue collapse. The strategy was rational for direct revenue, but paywalled text is hard for any machine reader to use.

Healthcare at 38.7 is the worst category by a wide margin. The 9-point gap between Healthcare and Media is larger than the entire spread from SaaS to Fintech. Healthcare DTC brands gate clinical content behind sign-ups, rely heavily on JavaScript for product pages, and frequently use anti-bot defenses to prevent automated abuse. Each decision is defensible in isolation. The combined effect is a category that AI search engines struggle to read at all.

“Healthcare DTC brands gate clinical content, rely on JavaScript, and use anti-bot defenses. Each decision is defensible in isolation. The combined effect is a site that machines can barely read.”

Three Brands Radar Could Not Scan

Three brands in the index returned no meaningful audit data. Chime in fintech, Quartz and The Information in media. We mark them Audit Blocked rather than scoring them zero, because zero implies bad content. These brands have content. The Radar scan could not read it.

The Information is the clearest case. The publication is a paid subscription with a hard paywall. The Radar scan of a story page got a login prompt, not the article. Subscribers see the writing; a crawler without a subscription does not.

Quartz has a similar profile, though softer. JavaScript-heavy rendering combined with paywall mechanics meant the Radar scan saw much less than a human visitor does. The brand has high awareness in business journalism circles.

Chime is the most surprising of the three. The challenger bank has tens of millions of users and a substantial public presence. The audit failure traces to anti-bot defenses, likely Cloudflare-level rules that block non-browser user agents from accessing content pages. The decision is reasonable from a security standpoint. If AI crawlers are blocked the same way, AI assistants cannot reach the content that would let them describe Chime accurately to a user asking about challenger banks. The Radar scan does not test AI crawlers directly.

These are not failures of the audit. They are findings. The Audit Blocked treatment in the public index page explains that Radar could not scan these brands. The index distinguishes a blocked scan from poor optimization, and that distinction is important. A brand that scores 30 has clear technical work to do. A blocked Radar scan needs investigation before drawing conclusions about AI-crawler access.

What This Means for Your Brand

Three takeaways from the data, in order of importance.

One. Brand recognition does not predict AI readiness. The top of the index is dominated by SaaS companies and a handful of e-commerce challengers. The bottom is full of names that have spent years building consumer trust through content. The technical work that makes a brand readable to AI search engines is different from the creative and editorial work that makes a brand resonate with humans. A team can be world-class at one and below average at the other. Most are.

Two. The structural decisions that drive low scores are usually rational responses to other problems. Paywalls protect revenue. Sign-up walls protect conversion data. Anti-bot defenses protect against scraping abuse. JavaScript rendering enables modern UX. Each decision has a defensible business case. The combined effect is a site that machine readers struggle to parse. This is a strategic choice now, not an oversight. Brands have to decide which audience matters more: human visitors who can navigate paywalls and JavaScript, or AI crawlers that cannot.

Three. The path from low to high score is shorter than people think. The technical fixes (allowing AI crawlers in robots.txt, completing structured data, server-rendering critical pages) are well documented. None of them are research projects, though most sites still fail answer-engine optimization anyway. A brand at 30 can move up with focused technical work. The brands at the top of the index do not have proprietary technology. They have technical hygiene that the bottom of the index lacks.

If your brand sits in the lower half of the index, walk through Why is my company invisible in AI search results? to identify which of the three failure modes is dominant for your domain.

The Radar Brand Index will keep re-scanning these brands. Brands that improve their technical readability will move up. Brands that double down on paywalls and anti-bot defenses will stay where they are. The index will be the public record of which choice each brand made.
