📊 More insights into ChatGPT’s August citation shifts via @Similarweb ! We already knew about the Reddit and Wikipedia declines, but 1) Where did this citation share go and 2) Did the shift look the same across industries? Similarweb shared with me this additional analysis of US desktop data, comparing August vs July 2026 across all prompts, as well as Beauty, Finance, and Travel ones. A few findings that stood out: * Across all 4 segments, Social Media, Reference Materials, and News & Media were the biggest 3 declines. This includes Reddit and Wikipedia. * For the 3 industry segments, the biggest increases were often in category relevant site types. E.g. Travel prompts saw Travel sites become a lot more frequently cited. This means brands in that category have a bigger chance of being cited * Citations are no longer dominated by a few UGC sites and moving towards category specific sites Take a look at the data here 👇 Thanks so much, @AdelleKehoe for the insights 🙌

More and more consumers are buying through AI, sometimes without ever leaving the LLM. So brands have to ask: Is AI recommending your products? And is that driving real sales? @NielsenIQ partnered with Similarweb on a new Agentic Commerce Measurement solution to answer exactly that: → What buyers are asking AI assistants → Where your products rank in AI recommendations → Whether your product data is optimized for AI agents → How AI discovery converts into real sales Full announcement below.

In less than a year, the share of AI answers containing web citations has increased more than fivefold. Read more on the topic in our Gen AI Landscape report:
