How to refresh old content so it ranks
|
Hello Reader! Last week we talked about how investing in refreshed content might just be the best TOFU strategy of 2026 (see the post here). The argument landed, judging by my inbox, but it left one question hanging. How do I refresh content so it ranks without burning the same hours a new post would take? This week is the how. Ahrefs analyzed 17 million AI citations and found that pages cited by AI assistants average 1,064 days old, compared to 1,432 days for organic results. That's 25.7% fresher, a full year younger. ChatGPT leans hardest toward new pages, while Google's AI Overviews and organic results are the most forgiving of older ones. So the more your audience lives in ChatGPT, the more freshness matters. Seer Interactive's July study pulled 47,097 citations across ChatGPT, Gemini, and Perplexity and kept only the pages cited three or more times, the ones the models genuinely lean on. Of the pages they could date, 72% had been updated in the past year, but only 42% were published in the past year. The freshness these models reward comes from maintaining older pages, so here's how to do the maintaining: 1. Let citation data pick your refresh list. Skip the guesswork about publishing cadence. Pull the pages AI assistants and Google already cite (or used to), and start there. A page with citation history has proven the models trust it, and a refresh renews the lease. Invest in AI-visibility tools to help you. 2. Sort every candidate into a quick update or a rewrite. This is how Ahrefs runs its own refresh program. Quick updates are minimum viable fixes with outsized returns, like swapping a dead stat, replacing a changed screenshot, or tightening an intro that buries the answer. One writer can clear several in an afternoon. Rewrites are for pages where the argument itself has aged, the search intent has moved, or the piece needs to serve a second business goal like supporting a product launch. Most pages need the first. Save rewrites for pages that earn the investment, because the biggest refresh mistake is giving every page the full-remodel treatment when 80% of your library only needs a coat of paint. 3. Change the substance, never just the date. Crawlers compare your page body against prior versions, so a new date on old words fools nobody. Worse, it can cost you trust with returning readers who remember the piece. A real refresh changes what the page knows. You need new data, current examples, sections covering what's happened since you hit publish. If someone read the old version and the new version back to back, they should learn something different from the second one. 4. Hunt down anything older than a year. You'll need to replace stats, screenshots, pricing, tool walkthroughs, examples, and expert quotes that are tied to a moment that has passed. A good rule of thumb: If a number predates 2025, it either gets a current source or it gets cut. 5. Say what you changed, in places humans and machines both read. Add a short dated note near the top, something like "Updated September 2026 with new citation data." Here's an example of an updated post I wrote for Shopify: Readers trust a visible update stamp, and that stamp converts your invisible work into visible credibility. Then make sure the machine-readable signals match your on-page note. Seer dated pages in its study using schema, sitemaps, and headers, which means those three fields are exactly where AI systems look to decide whether your page is fresh. If your sitemap's lastmod date still shows 2024 after a September refresh, you did the work and hid the receipt. Happy Refreshing!
