How often should website content be updated for AI search freshness?

Review and update key pages whenever information changes, and schedule regular content audits—typically every three months for competitive topics and every six to twelve months for evergreen resources. Prioritise pages that drive conversions or answer high-intent queries, checking for outdated stats, changed product details, new regulations, or shifts in best practice. When you update, make the changes visible with clear "last updated" dates and, where relevant, short change logs or added FAQs so AI engines can see both freshness and added depth. AI engines favour content that is not only recently updated, but also reflects current reality on accuracy-sensitive topics like pricing, compliance, and fast-moving industries.
