How often should I update content for AI Search?

Content Update Cadence is the rhythm at which important pages are reviewed, refreshed, and improved. In AI search, freshness matters because AI assistants and search engines need current facts, pricing, product capabilities, statistics, and recommendations. A good cadence depends on the page type: fast-changing product and comparison pages may need frequent reviews, while evergreen glossary pages can be updated when terminology, examples, or market behavior changes. The best SEO and GEO programs track which prompts and citations each page supports, then prioritize updates where buyer intent, competitor positioning, or AI answers have shifted.
