Content Decay
Content MarketingAlso: Content Erosion · Traffic Decay
Quick definition
Content decay is the gradual decline in a piece of content's organic traffic after it peaks. It usually happens because the information becomes outdated, newer competitors outrank it, search intent shifts, or Google quietly downgrades its ranking signals over time.
How it varies across Australia
Most published content peaks within six months and then enters slow decay. Across the Australian content sites we've reviewed, the largest traffic losses come from posts that were never updated after the first three months. The opportunity is rarely 'write more.' It's 'refresh the ones already ranking.'

Content decay is the slow leak most content programs ignore until it's too obvious to ignore. A post ranks, traffic rises, you celebrate, you move on to the next thing. Six months later, traffic is half what it was. Twelve months later, the page is on page two and you're not sure why.
Decay is caused by a few overlapping forces. Information becomes stale (prices changed, screenshots are outdated, the tool you reviewed launched v3). New competitors publish stronger versions of the same answer. Search intent shifts as the topic matures. And Google's algorithm quietly rebases what 'good' looks like for that query.
The fix is almost always cheaper than writing new content. A 30-minute refresh of a decaying post often recovers more traffic than three new posts in the same topic cluster. Most content teams don't do it because measuring decay requires looking at last year's content, and last year's content isn't where attention goes.
A blog post is a perishable asset. Treat it like fresh produce, not like furniture.
How it shows up
Content decay shows up in Search Console as a downward sloping line on specific URLs. The most diagnostic signal is the gap between peak traffic and current traffic. If a post peaked at 4,000 monthly clicks and now does 1,200, that's a 70% decay signal. If most of your top-twenty pages show that pattern, your content strategy is leaking faster than it can replace itself.
It also shows up as ranking drops on tracked keywords, falling click-through rates as competitors test better titles, and (eventually) deindexing if the quality signals drop too far.
The Australian context
Australian content sites are particularly vulnerable to decay because the Australian search universe is smaller. Once a global competitor moves above you on a generic query, the local share you held often disappears. The defence is industry-specific or location-specific content that global sites won't bother to produce.

Common questions
How fast does content decay?
Most content peaks within six months of publication and starts losing traffic within twelve. Posts in fast-moving categories (tech, marketing, AI) decay faster. Posts in slow-moving categories (legal, accounting fundamentals) can hold for years.
How do I tell if my content is decaying?
Compare each top-ranking page's last-month traffic to its all-time peak in Search Console. Anything below 70% of peak is decaying. Anything below 40% is in active decline and urgent.
Is refreshing better than rewriting?
Refresh first. Update the information, swap in better examples, improve the intro, add a recent section. Rewriting from scratch loses the existing URL's ranking authority. Only rewrite if the original is structurally broken.
How often should I refresh content?
Top-performing posts: every six months. Mid-tier posts: annually. Long-tail posts: when search volume or competition meaningfully shifts. Set a calendar reminder for the top twenty pages, not for everything.
