Content libraries often grow by addition. New articles appear while old service names, outdated examples and broken next steps remain untouched. Over time the site becomes larger without becoming more useful.
Maintenance can be simple: review important pages, update changed information, improve internal links and consolidate overlapping pieces. A page does not need a cosmetic rewrite simply to change its date. It needs a review when there is something meaningful to improve or confirm.
That approach is better for customers and easier to manage. A smaller set of maintained resources can communicate more authority than a large archive nobody is willing to revisit.
