37 platforms ranked by AI citations

A platform, here, is a large website where content is published by users, sellers or the company itself, and that AI models reach when they build an answer. The index brings together very different families of sources:

• Reference and publishing: Wikipedia, Medium, WordPress.
• Reviews and ratings: Trustpilot, TripAdvisor, Yelp, Glassdoor.
• Video, music and streaming: YouTube, TikTok, Twitch, Spotify, Netflix.
• Communities and Q&A: Reddit, Quora, Stack Overflow, Discord, GitHub.
• Social networks and messaging: LinkedIn, Facebook, Instagram, Twitter/X, Pinterest, Snapchat, WhatsApp.
• Marketplaces and listings: Amazon, Shopify, Leboncoin, Indeed.
• Software and technology vendors: Microsoft, Apple, Salesforce, HubSpot, Notion, Slack, Zoom, Figma, Canva.

Google is deliberately left out. It is the search infrastructure behind many AI answers rather than a source cited for its own content, and counting it would blur the picture.

Each card shows citations per 100 AI answers: out of 100 answers given by the five models, how many cite the platform. The value is an average over the whole tracking period, so a platform that took off recently can sit below one that has been steady for longer.

Open a card to see the detail: the split by model, the month-by-month curve in French and in English, and the industries where the platform is cited most. A Versus page puts two platforms side by side.

A low value does not make a platform irrelevant. GitHub or Stack Overflow can be central for a narrow set of technical questions and absent everywhere else, which pulls their average down.

GEO (Generative Engine Optimization) is the work of making a brand visible in AI answers. Much of what an assistant says about a business comes from outside its website: reviews, community threads, video tutorials, encyclopedic entries. The platforms ranked here show where models look for that outside view.

The practical question is which of them fits your sector. A hotel has more to gain on TripAdvisor than on GitHub, and a developer tool the reverse. The industry index completes this page by showing the platforms cited for each sector.
