What is Content Decay Rate?
The speed at which a piece of content loses organic traffic or engagement over time after its initial performance peak.
Content Decay Rate Explained
Content decay rate quantifies how quickly a page or article loses traffic after reaching peak performance. A high decay rate indicates content that is time-sensitive, topic-dependent, or outcompeted by newer content from competitors. Measuring decay rate helps prioritize the content refresh queue: pieces decaying fastest and generating the most traffic loss are typically the highest-value refresh candidates. Decay rate is calculated by comparing current traffic to peak traffic over a defined period, often expressed as a percentage decline per month or quarter.
Frequently Asked Questions
How do you calculate content decay rate?
Take the peak monthly traffic of a piece, compare it to its current monthly traffic, calculate the percentage difference, and divide by the number of months elapsed to get a monthly decay rate. For example, a page that dropped from 5,000 to 2,000 sessions over 12 months has approximately a 25% annual decay rate.
Which content types decay fastest?
News articles and trend-based content decay very rapidly, often within weeks. How-to guides and listicles on competitive topics decay moderately as competitors publish updated versions. Evergreen conceptual content typically decays slowly but still requires periodic refreshes to maintain ranking.
How can you slow content decay?
Regular content refreshes, internal link updates, and expanding coverage to match current search intent are the most effective tactics. Structured data, updated statistics, and new sections that address evolved user questions can reinvigorate a decaying page without a full rewrite.
