Refresh AEO content when the underlying information changes or when evidence shows an important customer need is not being met. Prices, availability, policies, product details, and platform requirements may need attention quickly, while stable educational explanations may need less frequent review. Keep an owner and review date for important pages, and update the substance rather than changing a date to make unchanged material look new.
As a working cadence, review priority visibility data monthly and use more frequent checks during a focused launch or investigation. Schedule a broader content review quarterly, then adjust the frequency to your industry’s rate of change and available resources. These intervals are operating recommendations, not search-engine requirements. Use repeated observations and business outcomes to guide changes, avoiding constant rewrites triggered by a single unusual AI answer.
