The Independent's social commerce revenue surpasses SEO

The Independent's social-commerce revenue surpassed its SEO-based revenue for the first time in September, indicating a shift toward social platforms and away from search traffic, which has declined partly due to AI. CEO Christian Broughton declared the old search-and-social model 'dead' and outlined four growth areas: AI, creator-led studio work, e-commerce, and membership, expected to contribute nearly half of 2026 revenue. The company reported £55.1 million in 2025 revenue, up 4%, with profit before tax rising 9% to £3.5 million. Broughton also highlighted AI productivity gains, including the 'Bulletin' news app with 12 million monthly users, the 'Eva' AI feature that reduced bounce rate, and a live news team six times more productive. Meanwhile, Meta's upcoming terms update on October 30 extends AI training scraping rights to all linked websites, criticized as a data grab that may override robots.txt and bypass licensing. In parallel, e-commerce platforms are navigating AI agent integration, with Amazon blocking third-party agents while Walmart and Target partner with OpenAI, and Zillow licensing data to Google for Gemini.
