SEO expert Aleyda relays an observation from Tomek Rudzki of peecai: Reddit and YouTube have declined as ChatGPT citation sources since the GPT-5.6 rollout.

Her takeaway: don't treat third-party citation optimization as a one-trick pony — every major model update can shift which platforms gain or lose prominence as citation sources, entirely outside our control. What is controllable is building a useful, relevant brand presence across the platforms and communities where your audience actually is, aligned with community management, digital PR, and broader campaigns — so visibility and authority survive citation volatility.
