Content Freshness Gap Finder

Fetch a sitemap and see which pages are fresh, aging, or stale based on their lastmod date, with the oldest pages listed first so you know what to refresh.

Enter a full sitemap address, or just a domain to try /sitemap.xml automatically.

About this tool

This tool fetches the sitemap you enter and reads the lastmod date on every page it lists, then sorts every page from oldest to newest so the pages most overdue for a refresh are immediately visible. Pages updated within the last 6 months are marked fresh, pages between 6 and 18 months are aging, and anything older than 18 months is marked stale. A page with no lastmod date, or one that could not be read as a valid date, is shown separately as unknown age rather than guessed at. This only reflects what the sitemap itself reports: a page can be edited without its lastmod being updated, and a sitemap missing lastmod entirely will show every page as unknown age.

A concept worth knowing by name here is Query Deserves Freshness, or QDF, a real part of how Google ranks results, first described publicly by Google Fellow Amit Singhal back in 2007. QDF means Google boosts recent content specifically for queries where freshness genuinely matters, breaking news, trending topics, current prices, this year's version of something, rather than applying a blanket bonus to newer content everywhere. That is exactly why this tool sorts by age instead of assigning a single freshness score: whether a stale page is actually a problem depends entirely on whether its topic is one where being current matters, not on the raw number of months since it was last touched.

Frequently asked questions

Search engines use freshness as one signal among many, particularly for topics where accuracy changes over time, such as pricing, statistics, or how-to instructions. Beyond search engines, stale content is also a real trust signal to human visitors: a page that visibly has not been touched in years reads as neglected, whether or not its information is still accurate.
From the lastmod field in the sitemap itself, the same field search engines read for the same purpose. This tool does not fetch or analyze each individual page, only the dates the sitemap already reports, so results are only as accurate as the sitemap is kept.
A sitemap entry is not required to include a lastmod date at all, and many sitemaps, especially auto-generated ones, omit it entirely or only fill it in for some pages. A page shown as unknown age was not skipped or ignored; there was simply no usable date available to check it against.
These are practical, general-purpose thresholds meant to separate genuinely current content from content that is worth a second look, not a rule search engines themselves publish or enforce. A page that intentionally has not changed because its subject has not changed is not necessarily a problem; this tool surfaces age as a starting point for review, not a verdict.
Search engines are generally understood to be skeptical of a lastmod date that changes without any real content change behind it, and doing this across many pages at once is a known pattern search engines have described discounting. The date is meant to reflect an actual update, not signal one that did not happen.
No. The address is used only to fetch that one sitemap file for that one check, and nothing is saved. Only public web addresses can be checked: requests to private or internal network addresses are refused.
Query Deserves Freshness, or QDF, is a real part of Google's ranking approach, first described publicly by Google Fellow Amit Singhal in 2007: Google boosts newer content specifically for queries where recency genuinely matters, such as breaking news, trending topics, or anything tied to a specific year or current price, rather than rewarding newer content across the board. This is exactly why a page's age alone does not tell the whole story: a stale page about a topic that never changes may be perfectly fine, while a stale page on a topic people expect current answers for is a real problem worth prioritizing first.
