Freshness is a ranking signal for some queries and completely irrelevant for others. Knowing which is which decides where you should invest in content refreshes and where you should leave pages alone. This page walks through which queries reward freshness, the test that tells you whether yours does, and what actually counts as a "real" refresh (spoiler: changing "2025" to "2026" does not).
Freshness isn't always good. Google tries to match the searcher's expectation. For "how to tie a bow tie," the best answer might be a page published in 2014. The knot doesn't change. For "best AI tools in 2026," the best answer is a page updated last month. The market changes constantly.
Your job is to figure out which category your query is in, then invest only where freshness matters.
Don't guess. Search your target query. Scan the top 10. Are most of them published or updated within the last 6 to 12 months? If yes, freshness is a factor. If most top-10 results are 3 to 5 years old and still ranking, freshness doesn't matter much. Invest your refresh budget elsewhere.
Google picks up and displays recent update dates in the SERP. A page with "Updated April 2026" gets clicked more than a 2019 page, even when the content is nearly identical. The visible date is a CTR signal as much as a ranking one.
Best practice:
datePublished, dateModified)Google's systems have gotten good at detecting fake refreshes. A changed dateModified with no real body changes doesn't earn freshness signals and can hurt trust over time.
For freshness-sensitive pages:
For evergreen pages, check annually. If nothing in the world has changed about the topic, leave it alone.
When you do a substantial refresh on a freshness-sensitive page, some SEOs change the published date as well as the updated date. This can trigger Google to re-crawl faster and occasionally boost rankings. Only do this when the refresh is substantial, not just cosmetic.
Open Search Console. Sort pages by traffic, descending. For the top 20 pages, check the age. Any over 18 months old, run the test, search the query and see how fresh the top 10 is. If the top 10 is freshness-sensitive and yours is stale, put it on the refresh list for this month.
Next: cannibalization and thin content, the two on-page mistakes that silently sink whole sites.
Not all pages need refreshing. Focus on:
Don't refresh pages that are already ranking well and stable. If you're #1 on an evergreen query, leave it alone. Refreshing adds risk of minor ranking changes for no upside.
