How to act on today's news

News in AI search moves fast and citation patterns churn 40–60% month over month, so treat each development as a trigger to re-measure rather than a reason to panic. The reliable weekly loop: keep AI search crawlers allowed, keep answer-first content fresh on the pages that earn impressions, and track your prompt set across engines so you see changes in your own mention data — not just in headlines.

• Re-run your tracked buyer prompts across ChatGPT, Perplexity, and Gemini
• Check robots.txt against the current AI bot matrix (bots change names and vendors add new ones)
• Refresh one impression-winning page with today's developments where genuinely relevant
