AI SEO Checklist for Old Posts: 15 Checks Before You Refresh

New drafts need a different pass. For those, use our 30-minute pre-publish AI SEO checklist, which checks a new article before its first crawl. This post covers what changes once a page has a history: traffic to protect, a URL with links pointing at it, and facts that were true when you wrote them. For the whole site at once, run an AEO audit instead.

Old posts are worth the effort. In Ahrefs' study of about 17 million AI citations, the average page cited by AI assistants was 2.9 years old, yet a full year younger than the average page in Google's organic results. Old pages still get quoted, and an old post with current facts is exactly what these engines like to cite.

The Refresh 15: An AI SEO Checklist at a Glance

The Refresh 15 is this AI SEO checklist in one table. Each check has a pass test you can answer yes or no. Work top to bottom, because the early checks can save you from doing the later ones.

Checks 1–3: Choose the Posts Worth Refreshing

The first three checks of the AI SEO checklist answer the question most refresh guides skip: should this post be refreshed, merged, or left alone?

Check 1: Demand

In Search Console's Performance report, group by page and look at the last three months. A post with impressions has demand. The Generative AI performance report adds how often your pages appeared in Google's AI features. A post that matches a buyer prompt you track counts too; our guide to measuring GEO shows how to build that prompt panel.

Check 2: A reason

A refresh needs a reason you can write down. Three cover most cases:

1. A fact changed. A price, a law, a product name or a statistic has moved on.
2. Clicks fell. Use the report's Compare option to set the last three months against the same months a year earlier. Google suggests weekly or monthly granularity, so the day of the week doesn't skew it.
3. An AI answer quotes it wrong. If ChatGPT or Perplexity repeats an old claim from your post, that post jumps the queue. Our guide to fixing incorrect brand facts in AI answers traces a wrong answer back to its page.

Slow traffic loss is called content decay, and the Compare view is the easiest way to spot it.

Check 3: One page per question

Two posts that answer the same question split your signals. Merge them into the stronger one and redirect the weaker URL. Google says a permanent redirect tells its indexing pipeline that the target should be canonical.

Checks 1 to 3 point to one of five outcomes:

With dozens of candidates, rank them before you run the AI SEO checklist on any one post. Our guide to optimizing content for AI search has a refresh priority score for that.

Checks 4–10: Fix the Facts, Answers and Sources

This is the part of the AI SEO checklist that changes the page itself, and where most of your time goes.

Facts and dates (checks 4 to 7)

Check 4 is the slowest and matters most. Open every source the post links to, confirm each figure still says the same thing, and date anything that can change: "as of September 2026." Google's quality questions ask whether content has "easily-verified factual errors."

Check 5 catches a common shortcut. Changing "2024" to "2026" in a title without updating the body promises something the page doesn't deliver. Change the year only when the content earns it. Leave the URL alone, even if it has a year in it. A new URL needs a redirect, and the old address is the one with the links and history.

Check 6 covers what ages fastest: broken links, retired features and screenshots of an old interface. Each one signals a page nobody has looked at in a while.

Check 7 is about honesty. Google's guidance on dates asks for a visible "Last updated" date plus dateModified in your Article markup. Google's helpful content guide warns against "changing the date of pages to make them seem fresh when the content has not substantially changed." A typo fix isn't a refresh.

Answers (checks 8 and 9)

Check 8 starts in Search Console. Click the post in the Pages view, then open the Queries tab to see what people search when they find it. Rewrite the first sentence so it answers the top query directly, with its key number or condition.

Check 9 uses the same list. Question queries the post shows up for, but never answers, are free topics. Give each one a heading phrased the way people ask it, and answer it in the first sentence below. Microsoft's guide to inclusion in AI search answers asks for the same thing: headings that reflect real questions, and claims anchored "in measurable facts."

Sources (check 10)

Studies get new editions, vendor pages move, and blogs vanish. Check that every statistic links to a live primary source that still says the same thing, and use the newest edition of any study. It's worth the effort: in the GEO study, adding citations, quotations and statistics raised a page's visibility in AI answers by 30% to 40%.

Checks 11–15: Reopen the Door and Re-Index

A refresh can be perfect and still invisible. The last five checks of the AI SEO checklist make sure crawlers can reach the new version, and know it's there.

Crawl access (checks 11 to 13)

Check 11. Rules written after a post went live can block it: a "block all AI bots" list, a firewall rule for scrapers, or a CDN bot setting. Cloudflare, for one, now sorts AI bots into Search, Agent and Training groups that are allowed or blocked separately. Paste your live robots.txt and the post's path into our robots.txt Tester, and confirm Googlebot, Bingbot, OAI-SearchBot, Claude-SearchBot and PerplexityBot are allowed. OpenAI says a site that blocks OAI-SearchBot won't be shown in ChatGPT search answers except as a navigational link. Our Cloudflare challenge trap guide shows where a blocked bot appears.

Check 12. Theme updates, CMS moves and new plugins can push content into JavaScript unnoticed. In a December 2024 analysis, Vercel found that none of the major AI crawlers render JavaScript. Fetch the raw HTML and search it for a phrase from the new opening:

curl -s https://example.com/blog/old-post | grep -c "a phrase from your new opening"

A count of 0 means those crawlers won't see the refresh. Repeat with a table cell and an FAQ answer, or run our AI Search Readiness Check for an outside view.

Check 13. An old post often has no links from anything written since. Link to it from two newer related posts, and link out from it to them. Google's AI features guide lists content "easily findable through internal links" among its best practices.

Re-index and baseline (checks 14 and 15)

Check 14. Tell each engine about the change the way it listens:

1. Sitemap. Update the post's lastmod. Google uses lastmod only when it's "consistently and verifiably" accurate, and a new copyright line doesn't count.
2. IndexNow. Send one ping. The IndexNow FAQ says a submission is shared with every participating engine. Bing takes part. Google doesn't. See our IndexNow glossary entry.
3. Search Console. Request indexing once in URL Inspection. Google says repeat requests won't speed things up, and crawling "can take anywhere from a few days to a few weeks."

Check 15. Before the refresh goes live, log the post's clicks and impressions for the last four weeks, its AI impressions, and whether it appears for a few prompts you track. Set a re-check date four to six weeks out. Without a baseline, you can't tell a refresh that worked from a quiet month.

Worked Example: A 2024 Tallyfold Post, Refreshed

Tallyfold is a fictional invoicing app for agencies, and every number here is made up. Its post "How to Set Payment Terms for Agency Clients (2024 Guide)" went live in March 2024. Over the last three months it had 4,200 impressions, but clicks fell 38% against the same months a year earlier. Tallyfold's editor ran the AI SEO checklist on it. Checks 1 to 3 passed: demand, a reason and no duplicate, so it was a refresh.

Of checks 4 to 13, the post passed 2 of 10 before and all 10 after, and checks 14 and 15 closed the job. It took about half a day. The check that mattered most is one many refresh guides leave out: a firewall rule written a year after the post went live was stopping OpenAI's search crawler from reaching it, however good the rewrite was. The AI SEO checklist caught it because it re-tests access on every refresh.

When checks 1 to 3 say rewrite instead, Rankbox's Citation-Ready Writer can draft the new version: it researches the live web and writes 2,000–3,500-word articles with their sources. You'd still run this AI SEO checklist on the draft, keep the old URL and add your own figures. Rankbox doesn't audit existing posts, manage robots.txt or track AI citations today.
