Most content has dateModified older than 18 months

dateModified is the schema field recording when a page was last substantively edited. This check looked across your articles and blog posts and found that most of them carry a dateModified more than 18 months old, meaning the bulk of your content hasn't been meaningfully touched in over a year and a half. AI engines and Google's freshness algorithms both weight recently-updated content more highly, on the reasoning that a page kept current is more likely to reflect accurate, up-to-date information. Content aged past 18 months without any update starts losing ground to more recently maintained competitor content, even if the underlying information hasn't actually gone out of date. Your content team should treat this as an ongoing quarterly task. Review your top-traffic content, update statistics, add new examples, fix any broken links, and update dateModified honestly whenever the edit is substantive enough to matter, rather than bumping the date without a real change behind it.
