How Often Should I Update Content for AEO?
Update content at the clock speed of its topic — fast-moving subjects like AI tools may need refreshing every few weeks, while stable evergreen topics can go many months. The rule isn't a fixed cadence but keeping each page accurate and current relative to how fast its facts change.
Update content at the clock speed of its topic — fast-moving subjects like AI tools may need refreshing every few weeks, while stable evergreen topics can go many months. The rule isn't a fixed cadence but keeping each page accurate and current relative to how fast its facts change.
Quick answer
At the clock speed of the topic. Volatile subjects — AI tools, pricing, shifting best practices — may need a refresh every few weeks; stable evergreen topics can go many months. There's no universal interval — keep each page accurate and current relative to how fast its facts change.
What determines the right cadence?
The topic's rate of change. A page about a volatile, fast-evolving subject decays quickly (content decay is well-documented) and needs frequent updates to stay accurate, while a page about a stable concept stays correct for far longer. So instead of one interval for everything, match each page's refresh schedule to how fast its facts actually move — the "clock speed" idea at the heart of the Freshness pillar and of running a refresh system.
How do I know a page is due?
Watch for decay signals. Outdated numbers, references to old tools or prices, or a shifted consensus all mean a page is due, and your citation tracking is another tell — a page that stops getting cited may have decayed relative to fresher competitors — AI-cited pages tend to be notably fresher than typical results. Treat those signals, not the calendar alone, as your trigger to refresh.
Update or publish new?
Usually update first. Refreshing a strong existing page to keep it accurate often delivers more than adding another page, because it preserves accumulated authority while restoring freshness. Fix what's decaying, then publish new content for genuinely new questions — maintenance and expansion are both part of staying current, but a decaying high-value page is the higher-priority fix.

- How often should I update content for AEO?
- At the clock speed of the topic. Fast-moving subjects — AI tools, pricing, fast-changing best practices — may need refreshing every few weeks, while stable evergreen topics can go many months. There's no universal cadence; the rule is to keep each page accurate and current relative to how fast its facts actually change.
- Does updating frequency depend on the topic?
- Entirely. A page about a volatile, fast-evolving subject decays quickly and needs frequent updates to stay accurate; a page about a stable concept stays correct far longer. Match your refresh schedule to each topic's rate of change rather than applying one interval to everything.
- How do I know when a page needs updating?
- Watch for outdated facts, dropped citations, and topic changes. If the page now contains stale numbers, references old tools or prices, or the consensus has shifted, it's due. Tracking your AI citations also helps — a page that stops being cited may have decayed relative to fresher competitors.
- Is updating old content better than publishing new?
- Often, yes. Refreshing a strong existing page to keep it accurate usually delivers more than adding another page, because it preserves accumulated authority while restoring freshness. Update what's decaying first, then publish new content for genuinely new questions.
