Link decay is the gradual decline in clicks or traffic that a published URL receives as time passes. Unlike link rot (where the destination disappears), the link itself remains valid, but fewer people click it.

The typical pattern is a sharp spike in clicks immediately after publication, followed by a rapid drop-off. For a shortened URL shared on social media, roughly 50% of all clicks occur within the first 3 hours, and click volume drops significantly after 24 hours. According to Bitly's public data, the average "half-life" of a shortened URL (the time for clicks to fall to half the peak) is about 3 hours.

Decay speed varies by platform. Twitter (X) decays fastest, with an average post lifespan of about 18 minutes. Facebook posts last several hours, blog articles several days to weeks, and search-engine-driven links can sustain traffic for months or years.

Visualizing link decay through a URL shortener's click analytics helps evaluate marketing effectiveness. Analyzing the decay curve of a campaign link reveals the optimal posting time, whether re-posting is needed, and the effective lifespan of the content.

Strategies to slow link decay include creating evergreen content (material whose value does not diminish over time), updating and re-sharing content periodically, securing search traffic through SEO, and redistributing links via email newsletters.

FAQ

What is the difference between link decay and link rot?

Link rot means the destination page has disappeared and returns an error. Link decay means the link still works but receives fewer clicks over time. The former is a technical problem; the latter is a content freshness issue.

How quickly do social media links decay?

On Twitter (X), a post's visibility in the feed is short, with a post lifespan of around 18 minutes, so clicks are concentrated in the short window right after posting. Facebook posts last several hours, and Instagram Stories expire after 24 hours. Decay speed correlates with how fast each platform's feed refreshes.

How can I slow down link decay?

Create evergreen content that stays valuable over time, secure organic search traffic through SEO, update and re-share content periodically, and redistribute links through email newsletters.
