Brought to you by GEOforge.\nIn this solo roundup, Paris Childress, founder of Hop AI and co-founder of GEOforge, covers nine stories from the week in AI search, led by Profound's new data showing that AI citations have a half-life.\nIn this episode:\n⏳ Your AI citations have a half-life\nProfound launched Citation Decay inside Answer Engine Insights. It calculates daily citation share on a rolling two-week average and tracks a URL's first citation, rise, peak, and half-life.

In its tracked B2B sample, ChatGPT mentioned brands in 40% of responses but recorded a 0% brand-controlled citation rate. Gemini showed 25% mentions versus 12% brand citations, and Perplexity 22% versus 25%.\n🥇 Brands are AI's first choice in only 29% of answers\nLeoprd analyzed 31,200 AI responses across 27 brands, seven categories, and eight platforms.
