"acceptedAnswer": {
"@type": "Answer",
"text": "ChatGPT's share of measurable B2B AI referrals fell from 89% to 62.6% between 2025 and March-April 2026, per Goodie's AI search traffic analysis. The decline happened as Claude, Gemini, and Perplexity grew their user bases and citation surfaces simultaneously. Claude reached 18.5% of B2B AI referrals, Gemini reached 10.6%, and Perplexity reached 7.3%. ChatGPT's total visit count stayed roughly flat — its share fell because competitors grew faster, not because ChatGPT itself shrank."

"@type": "Question",
"name": "Do ChatGPT and Perplexity cite the same sources?",
"acceptedAnswer": {
"@type": "Answer",
"text": "No. Only 11% of domains cited by ChatGPT also appear in Perplexity, per a 2026 analysis of 680 million citations. ChatGPT and Perplexity draw from fundamentally different citation pools and apply different retrieval filters. Optimizing for one engine does not transfer to the other. Brands that treat AI search visibility as a single-platform problem are invisible to the majority of AI-driven referral traffic."

"@type": "Answer",
"text": "Gemini has the highest brand citation rate at 19.8% of checks, followed by Perplexity at 18.9%, ChatGPT at 14.3%, and Claude at 8.0%, per 2026 brand citation tracking data. Perplexity cites an average of 21.9 sources per response, more than double ChatGPT's 10.4. Despite Claude's lower citation rate, Claude visitors convert at 16.8%, higher than ChatGPT at 14.2% and Perplexity at 12.4%."
