New analysis on AI content sources

A new analysis of AI citations reveals that most AI-generated answers from ChatGPT, Gemini, and Perplexity rely heavily on brand-controlled content. Companies, not publishers, are shaping what users see in AI summaries. For marketers, owning and optimizing branded content for AI visibility could soon be as essential as SEO—now’s the time to adapt your content strategy.

Google Ads cracks down on poor visuals

Google Ads has begun flagging low-quality images across campaigns, signaling a stronger push for creative excellence and user trust. Blurry or overly compressed visuals may reduce ad delivery, adding a fresh layer of accountability for advertisers. For marketers, creative quality control just became a measurable metric that can directly affect ad performance.

Duolingo enters the ad platform game

Duolingo has unveiled a new ad platform built with Adobe, designed to bring more premium inventory to brands aiming to reach its younger, highly engaged audience. The move positions Duolingo as both a publisher and an ad partner, blending education with brand storytelling in a trusted environment. For marketers, it’s a chance to test a new, high-attention channel where younger consumers are both active and receptive.
