Content Decay
Content decay is the slow drop in how often people find and click a page over time. On Google's Search Off the Record podcast, Lizzi Sassman said in SEO it usually means content declining in search interest, which can show in Search Console as a dropping click rate. John Mueller added the world moves on while the page stays put.

What Content Decay means for your business
Mueller said not every page needs to be new, and that people often treat decay as a direct SEO factor when it's more of a strategy question: what you want your site known for, whether that matches what people look for, and whether the information is still correct.
We'd look for it on the pages that used to bring in calls, like a pricing page, a guide that names a product you no longer carry, or a service page written for questions buyers stopped asking. In Search Console, we'd compare each page's clicks and impressions with the same months a year earlier, then read the page the way a buyer would today.
When a page has slipped, we'd fix the content first. That might mean new facts, a clearer opening, or folding the page into a stronger one. Our content freshness entry covers when to change the date.
If a page that used to bring in work has gone quiet, rewriting it for the buyer asking today is where we'd start.
