What content decay actually looks like
At its best the day it launches. Then it fades.
Slowly enough that a year is gone before anyone notices. People hear content decay and picture a broken page: a 404, a busted image. That is not it. The page loads fine, looks fine, reads fine. It just does not get found anymore.
The traffic does not fall off a cliff, which is exactly the problem. Decay is a long, gentle slope. A few percent a quarter, and people are terrible at noticing a few percent a quarter. You only see it when you pull two years onto one chart and go: oh. Oh no.
Three things are happening, and they move at different speeds. The world moved and the page did not. Somebody out-wrote you. And the search itself changed, so people stopped phrasing the question the way they did when you wrote the page. Your rankings for the old phrasing hold fine. Nobody types it anymore.
The page did not get worse. Theirs got better.
Which one is hitting you.
Stale stats, old screenshots, prices from two product cycles ago. Nothing broke. The facts just quietly stopped being true, and the page kept stating them.
Or a competitor published something more complete, earned a few links, answered the follow-up you missed, and walked past you.
Or people stopped phrasing the question the way they did when you wrote the page. Your rankings for the old phrasing hold fine. Nobody types it anymore.
Decay is silent, so it loses every budget fight to the loud problems. And it just keeps bleeding.
The fix is simple, not fast.
Find the bleed. In Search Console, pull Performance, compare a date range against the same range a year earlier, sort by clicks, and flag anything down more than twenty percent year over year. Beacon runs this exact comparison as part of its audit, so you don't have to build the spreadsheet by hand.
Then triage. Not every decaying page deserves saving. The ones worth your time are the pages that used to convert. Spend the effort where the traffic was worth money.
A website is a garden, not a monument.
Decay is just what unattended gardens do. Look at the slow chart on purpose, before late becomes too late.
Improve, then bump the date. Update the stale facts, answer the new questions, redo the screenshot, add internal links from your strong pages, and only then bump the publish date. Bumping the date without improving the page is a trick, and Google has gotten good at spotting it. The SEO ground-truth worksheet is the same checklist we hand clients before that pass, so nothing gets missed.
