AEO Content Refresh Cadence: When to Re-Optimize for Re-Citation

If citation half-life is the problem (median 6 weeks of decay), refresh cadence is the answer — but only if it's done right. Most teams either over-refresh (date-only spam, which Google has learned to discount) or under-refresh (set-and-forget). Here's the cadence that actually drives re-citation, broken down by content type.

What does 'refresh' actually mean in 2026?

Refresh cadence by content type

AI/AEO tactical content: every 6 weeks (fast-moving). Industry benchmarks and case studies: every 12 weeks. YMYL content (medical, financial, legal): every 12 weeks minimum, with documented reviewer sign-off. Evergreen definitions and how-tos: every 6 months. Original research and benchmark studies: annually with full re-collection. **Match velocity to topic velocity — not to the calendar.**

The 4 edits that drive re-citation

1. Updating an inline statistic with a newer source (cite the year explicitly). 2. Adding a new FAQ Q/A pair reflecting an actually-asked question that month. 3. Adding a new H2 + 40–80 word direct answer block addressing a sub-question. 4. Updating an outbound citation link to a fresher source. **All four signal real research effort to both Google and AI engines and reliably produce re-citation within 2–4 weeks of refresh.**

The 4 edits that don't (and why)

1. Date-only updates with no content change — discounted. 2. Cosmetic restructuring (renaming H2s without changing content) — neutral at best. 3. Removing internal links to add new ones with no net signal — wash. 4. Adding generic intro padding (no new information) — risks helpful-content demotion. The pattern: changes that don't add information value don't earn re-citation.

The refresh tracking spreadsheet

Columns: URL, content type, target cadence, last refresh date, next refresh date, refresh type planned, post-refresh citation check date. Review weekly, schedule the next 4 weeks of refreshes. Without a tracking artifact, refreshes default to 'whatever's on top of mind' — which is the wrong pattern entirely.
