On <time datetime="2026-05-07">May 7, 2026</time>, OpenAI changed how ChatGPT surfaces brands in answers. Footnote citations became inline clickable links placed inside the response text. Brand referral traffic jumped 157.7% week-over-week, and homepage referrals surged 354.7%, per Similarweb's clickstream data. ChatGPT's citation volume also fell 86–94% across key markets between February and April 2026. Fewer brands get cited. Those that do receive far more traffic per mention. BrandCited tracks which side of that divide your brand sits on across eight AI engines.

BrandCited's free scan shows your citation rate across ChatGPT, Perplexity, Claude, Gemini, Copilot, Grok, You.com, and Brave. Run it at brandcited.ai to see where you appear and where you don't.

What did ChatGPT change on May 7, 2026?#

ChatGPT swapped footnote-style citations for inline clickable brand links embedded inside answer text. Before <time datetime="2026-05-07">May 7</time>, brands appearing in ChatGPT answers showed as plain bold names with citation chips at the bottom of the response. After May 7, those same names became clickable callouts that link straight to the brand homepage, placed inline next to the relevant claim.

The share of ChatGPT responses containing an inline brand link jumped from 0.4% to 6.2% on May 7, a 14x increase on a single day, per Profound's tracking across thousands of monitored queries. Before the update, roughly 26 to 32% of ChatGPT referrals landed on brand homepages. After, that rate jumped to around 60% and stayed there.

The user experience change is the mechanism behind the traffic numbers. A citation chip at the bottom of a 300-word answer is easy to skip. An inline link embedded in the sentence that mentions your brand is harder to ignore. Users clicking from an inline mention arrive at the front door of a brand, not three levels deep in a blog post.

How much did brand traffic change after the update?#

Total ChatGPT referral traffic to tracked brand websites increased 157.7% week-over-week after <time datetime="2026-05-07">May 7, 2026</time>, per Similarweb's clickstream data. Homepage referrals surged 354.7% in the same window.

B2B Software and SaaS brands saw the largest absolute gains. Daily OpenAI referrals to monitored brand sites in that segment rose more than 200% above the pre-May 7 baseline. ChatGPT referral traffic converts at 7.1%, placing it second only to paid search at 7.8% among inbound channels, per ALM Corp's analysis of Q1 2026 brand traffic.

In retail, AI-referred traffic to U.S. sites grew 393% year-over-year in Q1 2026, and AI-referred orders on Shopify grew nearly 13x over the same period, per Shopify's enterprise data. AI-referred visitors convert 42% more often than visitors from organic search. ChatGPT is no longer a brand awareness channel with a vague halo effect. It's a measurable acquisition channel with conversion rates competitive with paid media.

<section id="why-chatgpt-cites-fewer-brands">

Why is ChatGPT citing fewer brands while traffic per mention surges?#

ChatGPT cut its citation volume 86–94% across key markets between February and April 2026, per SEOClarity's global citation analysis. The analysis covered the U.S., UK, Canada, Germany, and Italy and identified two specific algorithmic shifts as the cause: <time datetime="2026-03-08">March 8</time> and <time datetime="2026-04-19">April 19, 2026</time>.

The U.S. zero-citation rate (the share of ChatGPT responses that include no citation at all) doubled in March 2026, from 28% to 48%. OpenAI is relying more on parametric training knowledge for answers and less on live web retrieval. When ChatGPT does cite, it now cites fewer sources per response. Both levers move together, compounding the impact.

The result is a narrowing field. Fewer brands get cited. Those that do receive inline links rather than footnotes, driving far more traffic per mention. A brand that survived the citation cutback is now winning a larger share of a smaller pool, with each win delivering twice the homepage traffic it did before May 7.

Which brands does ChatGPT cite and link after the May shift?#

ChatGPT cites brands whose content appears at high frequency in its training data and that carry consistent entity signals across the web. AuthorityTech's 2026 analysis found that 80% of pages ChatGPT cites don't rank on the first page of Google. Organic search position is not the primary predictor of AI citation.

Third-party presence matters more than self-published content for ChatGPT citation. Brands with Trustpilot profiles have a 53.5% citation rate in AI responses versus around 1% for comparable brands without them, according to third-party citation research cited by AEO Engine. Review platforms, directories, and trade publications all contribute to the external signal that tells retrieval systems a brand is real and worth citing.

The structural predictor is entity clarity: the consistency with which a brand is described in the same terms across multiple external sources. When ChatGPT's training data contains three different descriptions of what your brand does, the model is uncertain which version to cite. When every external source (Wikipedia, G2, Crunchbase, Trustpilot, trade press) says the same thing, the model cites with confidence.

<section id="how-to-track-ai-referral-traffic-in-ga4">

How do you track AI referral traffic to your brand right now?#

Google added a native AI Assistant channel to GA4's Default Channel Group on <time datetime="2026-05-13">May 13, 2026</time>. It tracks clicks from ChatGPT, Gemini, and Claude across every GA4 property with no custom filters or developer work required. Sessions from recognized AI assistants receive the medium value "ai-assistant" and appear under the AI Assistant channel in Default Channel Group reports, per Search Engine Journal's coverage of the launch.

GA4's AI Assistant channel has one key limitation: it can only classify traffic when the referring tool passes the referrer header with the request. Research into AI referral behavior estimates that 20 to 40% of actual AI-originated visits arrive looking like direct traffic, because mobile app environments strip referrer data. The GA4 channel captures web-referred AI traffic; dark traffic from native apps goes uncounted.

Perplexity, Microsoft Copilot, and You.com are not yet in GA4's recognized referrer list. Google's documentation uses the phrase "popular AI assistants," suggesting those platforms will be added in a future update. Until then, tracking Perplexity and Copilot citations requires a dedicated monitoring tool rather than GA4 alone.

ChatGPT is weighted at the appropriate share of BrandCited's composite score given its 62.6% market share among AI search tools. If your brand's ChatGPT citation rate dropped between February and April 2026 along with the platform-wide decline, BrandCited's trend chart shows when the drop happened, which query types were affected, and how your rate compares to tracked competitors. You can run BrandCited's free scan at brandcited.ai and see your citation rate across all eight engines in 30 seconds.

<section id="what-to-do-right-now">

What to do right now#

1. 1Check GA4 for the AI Assistant channel. Open Default Channel Group in GA4. If you see zero sessions under AI Assistant, either ChatGPT, Gemini, and Claude aren't sending traffic, or it's arriving as direct because you're getting mobile app clicks with stripped referrers. Both scenarios need a response.

1. 1Run a citation baseline. Check your brand in ChatGPT, Perplexity, and Claude right now. Record which query types surface your brand and which don't. This is your baseline before you make any changes. Without it, you can't measure whether what you do next works.

1. 1Audit your entity description for consistency. Search your brand name in ChatGPT. Check whether the description it gives matches what your homepage says, what your Crunchbase profile says, and what your top three third-party listings say. Inconsistency across sources suppresses the model's confidence in citing you.

1. 1Claim and update your third-party profiles. Brands with Trustpilot profiles have a 53.5% AI citation rate; those without have around 1%. Claim Trustpilot, G2 or Capterra, and Crunchbase. Update each with your current product description, using the same language across all three.

1. 1Rewrite your homepage above the fold. Since the May 7 update, 60% of ChatGPT referrals land on your homepage rather than a specific page. The first 100 words of your homepage are now the landing experience for AI-referred visitors. If a visitor can't tell within five seconds what you do and for whom, those visitors leave.

1. 1Track citation rate week-over-week. The May 7 update made AI citations a direct traffic channel. A drop in citation rate is now a drop in a real traffic channel. Set up BrandCited or GA4's AI Assistant channel to catch shifts before they compound.
