Content decay

Content decay is a slow decline, not a one-time drop. A page keeps loading fine and keeps ranking, just a little lower each quarter, because its facts have aged, a competitor published a more complete treatment of the same query, the search intent behind the query shifted, or the page stopped getting new internal links as the rest of the site grew around it.

It is easy to miss for exactly that reason. A broken page or a crawl error announces itself. A decaying page does not: nothing is technically wrong with it, so it rarely triggers an alert. It usually only shows up when someone compares a query's traffic this quarter against the same quarter a year ago, not by looking at the page on its own.

The fix depends on the cause. An outdated fact or example needs updating, not a rewrite. A competitor's stronger page needs the site to genuinely cover what that page covers and does not. A page starved of internal links needs to be reconnected into the site's current structure, not just refreshed in place.

Semantyra does not track a year of ranking history for every page, since most sites do not retain that in Search Console either. Instead it flags pages the site itself has not modified in a long stretch, based on the page's own dated metadata, as the population where decay concentrates. That is a leading indicator, not proof of decline: an old page can still be accurate, and a recently edited one can still be decaying for reasons a modification date will not show.
