Content Freshness for AI: The 90-Day Refresh Rule

If ScoutRival’s Site Audit flagged “Freshness,” it means one or more of your key pages hasn’t been meaningfully updated in a long time — and AI search engines lean toward content that’s recently changed. The fix isn’t a trick; it’s a light quarterly habit of keeping your most important pages genuinely current. This guide shows you exactly what to update, how often, and how to do it on any platform — plus the one shortcut that will hurt you.

Why freshness moves AI citations

AI search engines are built to answer questions with current information, so they favour pages that look recently maintained. The 2026 data is consistent on this. Multiple studies find that roughly half of all AI citations come from content less than 13 weeks old. Pages updated within the last 30 days earn an estimated 3.2× more AI citations than older pages — and one ChatGPT-focused study found the model cited pages updated in the last 30 days a large majority of the time. Ahrefs’ analysis of millions of citations found AI-cited content is meaningfully fresher than standard organic results.

Not every engine weighs freshness the same. Perplexity is the most aggressive — it leans on real-time retrieval and heavily favours recent content. Google AI Overviews behaves closest to traditional organic search. ChatGPT sits in between. Claude is the least freshness-sensitive of the major engines. So a refresh habit helps everywhere, but it moves the needle most on Perplexity-style surfaces.

The mechanism is intuitive: a page that was updated last month is more likely to reflect current prices, current facts, and current best practices than one last touched two years ago. The model can’t verify that directly, so it uses recency as a proxy for reliability.

The 90-day refresh rule (and what “refresh” really means)

Here’s the honest version of the rule most guides get wrong: freshness only counts when the content actually changes.

Search and AI systems can tell the difference between a page that was genuinely revised and one where someone just nudged the “last modified” date. Bumping the timestamp with no real edits doesn’t earn you a freshness boost — and repeated fake bumps can erode the trust signal, so the tactic actively backfires. Every refresh needs at least one genuinely new, substantive element.

The practical routine:

1. Pick your cornerstone pages — the ~10 pages that matter most: top service pages, your price guides, your main FAQ, your best-performing blog posts. You don’t refresh the whole site; you maintain the pages that earn citations.
2. Every ~90 days, make a real edit to each. A substantive refresh means one or more of:
   • Update prices, stats, or figures to current numbers.
   • Add a new FAQ or answer a new common question.
   • Update or add a cited source link.
   • Add a new example, tip, photo, or section that wasn’t there before.
   • Remove anything that’s now outdated or wrong.
3. Add a visible “Updated: [Month 2026]” line near the top of the page, so both readers and models can see it’s current.
4. Update the year in evergreen titles (”…(2026 Guide)”) — but only as part of a real refresh, never on its own.

One genuinely new element per page per quarter is enough. This is a maintenance habit, not a rewrite.

How to keep pages fresh on your platform

The underlying signal — a dateModified timestamp that changes when you edit — is emitted automatically by most platforms when you actually save changes. Here’s the path on each.

WordPress

1. Pages or Posts → edit your cornerstone page. Make your substantive change (new FAQ, updated price, refreshed stat).
2. WordPress updates the page’s modified date automatically when you click Update — and most SEO plugins (Yoast, Rank Math) emit an updated dateModified in the page’s structured data.
3. Add a visible “Last updated: [Month Year]” line just under your H1 — type it as a normal paragraph, or use a “last updated” option if your theme or SEO plugin offers one.
4. Update the year in the SEO title via Yoast or Rank Math if the page carries one.
5. Don’t use a plugin that batch-changes modified dates sitewide with no content edits — that’s the fake-freshness trap.

Wix

1. Edit the page or blog post and make your real content change.
2. Wix updates the post’s modified date on publish; blog posts show a visible published/updated date you can surface.
3. Add an “Updated: [Month Year]” line near the top of the page text.
4. Update the SEO title in the page’s SEO Basics if it carries a year.

Squarespace

1. Edit the page or blog post and make a genuine update.
2. For blog posts, you can adjust the post date to reflect a real refresh — but only after making real edits.
3. Add a visible “Updated: [Month Year]” line in the content.
4. Refresh the year in the SEO Title under the page’s SEO settings.

Webflow

1. Edit the CMS item or static page and make your substantive change, then Publish.
2. If you run a blog as a CMS Collection, add an “Updated date” field and display it on the page — this gives readers and crawlers a visible recency signal.
3. Update the year in the page’s SEO title in settings.

Shopify

1. Edit the page or blog post under Online Store → Pages / Blog posts and make your real change.
2. Shopify tracks the updated timestamp; for blog posts you can show the date.
3. Add a visible “Updated: [Month Year]” line in the body.
4. Update the year in the page’s search-engine listing title.

Any other platform

Whatever your CMS, the rule is identical: change the content, let the platform update the modified date, show a visible “Updated” line, and put the current year in evergreen titles. The tool doesn’t matter — the real edit does.

Let a tool find what’s stale — you verify the facts

If you’re a ScoutRival customer, BlogCraft’s refresh can scan a cornerstone page and suggest what’s gone stale — an old stat, a missing FAQ, a dated example — and draft the update. As always, the tool can’t confirm your local facts. So the required step is yours: verify every price, number, and claim before you publish. Use it to spot the gaps and speed the writing; keep the truth-check in your hands. And never point it at your whole site to batch-touch pages — that’s exactly the fake bump that hurts you.

How to confirm it worked

• Open a refreshed page and confirm it shows a visible, recent “Updated: [Month 2026]” line near the headline, backed by real edits you can point to.
• Check that none of your cornerstone pages has gone more than 12 months untouched.
• View the page source and confirm the dateModified reflects your recent edit (most SEO plugins expose this in the page’s structured data).
• Re-run your ScoutRival Site Audit — the “Freshness” check should clear once your key pages carry recent, genuine updates.

Common mistakes to avoid

• Faking the date. Changing only dateModified (or a plugin that bulk-bumps timestamps) with no real content change doesn’t help — and repeated fake bumps erode retrieval trust. This is the single biggest mistake, and it makes things worse, not better.
• Refreshing everything at once. You don’t need to update your whole site quarterly. Maintain the ~10 cornerstone pages that actually earn citations; ignore the long tail.
• Rewriting for the sake of it. A refresh is one genuinely new element, not a from-scratch rewrite. Small, real, regular beats big and rare.
• Putting the year in the title without updating the page. “2026” on a page you haven’t touched is a promise the content doesn’t keep. Update the content first, then the year.
• Hiding the update. If you refreshed a page, show a visible “Updated: [Month Year]” line — it’s a recency signal for readers and models alike.
• Ignoring which engine you care about. If Perplexity visibility matters to you, freshness matters most there. Prioritise accordingly.

The bottom line

AI search rewards content that’s genuinely current, and the studies are consistent: fresher pages get cited far more often. The winning habit is small and honest — pick your ~10 cornerstone pages, make one real substantive edit to each every 90 days or so, show a visible “Updated” date, and keep the year current. The only way to lose is to fake it: a timestamp bump with no real change hurts you. Do the real work, lightly and regularly, and you stay in the answer.
