Key Findings
  • An X/Twitter post has a half-life of 49 minutes. 95% of all engagement ends within 24 hours of posting.
  • Instagram feed posts have a half-life of ~18 hours; Reels can surface for 2–4 weeks through the Explore feed.
  • Pinterest pins have a median active lifespan of 16 weeks, roughly 2,000× longer than a tweet.
  • SEO-optimised blog posts have a half-life of 2.03 years - the longest of any content type studied.
  • TikTok's median post lifespan is under 1 hour - views arrive in the first FYP push or not at all; viral exceptions can resurface for weeks.
  • YouTube evergreen videos can drive search traffic for months to years, but news and trending videos decay within 1–7 days.

Methodology

We combined two sources. First, GenSumo's own data - 173,000+ posts tracked across connected creator accounts (2025–2026), with Pinterest pins measured over a full 52-week window per pin. Second, published engagement research - including a longitudinal half-life study covering 5.6M+ posts, plus benchmark reports from Sprout Social, HubSpot, Hootsuite, and Orbit Media. Where sources conflicted, we favoured the larger sample. Full citations are in the Cite section.

Data Scope
  • Platforms covered: X/Twitter, TikTok, Snapchat, Facebook, Instagram (feed + Reels), LinkedIn, YouTube, Pinterest, and blogs
  • Half-life: Time for a post to receive 50% of its total lifetime engagement
  • Active window: Period of meaningful organic reach above 10% of peak performance
  • All figures are medians. Individual results vary by account size, niche, and content quality.

Content Lifespan Across Every Major Platform

Content lifespan - the time a post continues to receive meaningful organic reach - varies by a factor of more than 2,000 between the shortest-lived platforms (X/Twitter, TikTok) and the longest (Pinterest, blogs). The difference is not about quality; it is about architecture. Feed-based platforms rank content by recency. Search-based platforms rank by relevance.

Half-life figures from cross-platform longitudinal engagement research (5.6M+ posts) and GenSumo platform data. Active window estimates: GenSumo team research, 2025–2026, cross-referenced with Sprout Social, HubSpot, and Hootsuite benchmark data. * TikTok: median non-viral post; viral content can resurface for weeks. † Snapchat: Stories expire after 24 hrs by design; direct Snaps disappear on view.

Why the gap is so large: Feed-based platforms (X, TikTok, Facebook, Instagram) rank content primarily by recency. New content constantly buries older posts. Search-based platforms (Pinterest, YouTube, blogs) rank by relevance - meaning content published months or years ago competes directly with content published today.
03

Short-Lifespan Platforms: X/Twitter, TikTok, Snapchat

These three platforms share a defining characteristic: engagement is overwhelmingly concentrated in the first minutes to hours after posting. The feed refreshes constantly, new content displaces old, and the algorithm rewards freshness above all else.

X / Twitter: 49-Minute Half-Life

Longitudinal engagement tracking across 5.6M+ posts records the median half-life of an X post at 49 minutes - up slightly from 43 minutes measured in 2024 data. Despite this marginal change, 95% of a tweet's total lifetime engagement still arrives within the first 24 hours. Industry benchmark data from Sprout Social and HubSpot both corroborate this, noting that the typical visibility window in a follower's feed is 15–20 minutes for average accounts.

The short lifespan is structural. X's reverse-chronological and engagement-weighted feed continuously surfaces new posts. A tweet that doesn't earn early engagement (replies, reposts, likes) within the first 30–60 minutes effectively disappears. High-follower accounts or posts attached to trending conversations can extend this window to hours, but these are exceptions.

An X post has a half-life of 49 minutes. A Pinterest pin has a half-life of 16 weeks. That is a 3,265x difference in content longevity from the same publishing effort.

TikTok: 0-Minute Half-Life (With Viral Exceptions)

Published cross-platform engagement research records an effective half-life of under 1 hour for the median TikTok post - meaning most posts receive 50% of their total lifetime engagement almost immediately after going live. This reflects TikTok's For You Page algorithm, which delivers content based entirely on predicted engagement, not follower relationships or recency. A video either earns immediate watch-time and is amplified, or it is suppressed within the first hour. In practice, most views arrive within the first 1–2 hours after posting.

Strong completion rate re-enters the distribution cycle. Algorithm can resurface the video days or weeks later.

It is important to note that TikTok's half-life measurement has a bimodal distribution: most posts die within the first push window, but genuinely viral content can be resurfaced by the algorithm weeks or months later - a behaviour absent from Twitter/X. This makes TikTok's "~0 min" label accurate for the median post, but misleading as a universal rule.

The exception is viral content. Videos that achieve strong watch-time completion rates and share velocity can re-enter the algorithm's distribution cycle days or even weeks later. These are statistical outliers, not a reliable distribution model for most creators.

Snapchat: Ephemeral by Design

Snapchat Stories disappear after 24 hours by default; direct Snaps disappear on view. This gives the platform a structurally enforced content lifespan unlike any other major platform - the architecture itself sets a hard ceiling. Engagement data confirms this, recording an effective lifespan of under 24 hours for Snapchat content, with virtually all interactions tied to the notification window immediately after posting.

04

Mid-Lifespan Platforms: Facebook and Instagram

Facebook and Instagram both run on feed-based algorithms that weight recency heavily, but their slightly longer half-lives compared to X and TikTok reflect larger average post libraries, slower feed consumption habits, and algorithmic redistribution features like Explore and Reels.

Facebook vs Instagram: Half-Life by Format
Choosing the right format on Instagram multiplies lifespan by up to 20x.

Reels lifespan reflects active redistribution window via Explore and Reels tab. Sources: Cross-platform engagement research; Sprout Social; Later; GenSumo Research 2026.

Facebook: 86-Minute Half-Life, 5–6 Hour Active Window

Cross-platform engagement research records Facebook's post half-life at 86 minutes. This is consistent with Hootsuite benchmark data and BuzzSumo content analysis, both of which show that most meaningful engagement - reactions, comments, shares - accumulates in the first 5–6 hours after publishing. Facebook's organic reach has fallen sharply over the past decade, from ~16% in 2012 to approximately 1–2% in 2025, meaning the vast majority of followers never see any given post regardless of timing.

Posts in active Facebook Groups can exceed this window considerably. Group posts benefit from notification delivery rather than feed ranking, which means members are more likely to see and engage with content beyond the typical decay window.

Instagram: 18-Hour Half-Life for Feed Posts, 2–4 Weeks for Reels

Published engagement data records Instagram feed posts at a half-life of 1,096 minutes (~18 hours) - significantly longer than Facebook or X. Sprout Social and Later's platform research attribute this to Instagram's algorithm weighting saves and shares more heavily than likes, and its tendency to redistribute high-save content through Explore, extending reach beyond the immediate follower graph.

Instagram Reels operate on a fundamentally different lifespan model. Because Reels are continuously redistributed via the Reels tab and Explore feed based on engagement signals, high-performing Reels can surface for 2–4 weeks after publication. Exceptionally viral Reels have been observed driving views months later. This makes Reels the only Instagram content format with a meaningful long-tail.

Instagram Reels last 2–4 weeks. Instagram feed posts last 48 hours. On the same platform, choosing the right format multiplies content lifespan by 10–20x.

05

Long-Lifespan Platforms: LinkedIn, YouTube, Pinterest, and Blogs

These platforms share a common trait: content is ranked by relevance or recommendation quality, not just recency. This fundamentally changes the economics of content creation - a single piece of high-quality content can drive organic reach months or years after publication.

LinkedIn: 1–7 Days, With Algorithm Extensions

LinkedIn posts have an active engagement window of approximately 24–48 hours for typical content, with high-performing posts receiving extended distribution for up to 7 days via LinkedIn's "Dwell time" algorithm. Unlike Instagram or Facebook, LinkedIn's algorithm rewards content that generates meaningful comments and debate - and will continue to resurface such posts in the feeds of second-degree connections well beyond initial publishing.

LinkedIn is notable for occasional viral posts that resurface weeks later, particularly for thought leadership content shared by high-follower accounts. However, for most business accounts, the reliable engagement window is 1–3 days.

YouTube: 30 Days to 2+ Years for Evergreen Content

YouTube is the platform with the highest lifespan variance. News and trending videos can decay to near-zero views within 7 days. Well-optimised, keyword-rich tutorial or evergreen educational videos continue driving organic search traffic for months to years after upload. The key differentiator is whether the video ranks in YouTube search results for durable queries.

A 2015 AAAI study of 172,000+ YouTube videos found that nearly three-quarters of the top 5% most popular videos go through 3 or more distinct phases of popularity - including revivals months after initial decay. For SEO-focused creators, YouTube functions as the closest equivalent to blog content in terms of longevity potential.

Pinterest: 16-Week Median, Years for Evergreen Content

Pinterest pins have a median active lifespan of 16 weeks based on GenSumo's analysis of 173,000+ tracked pins. Evergreen categories - home decor, recipes, DIY, and gardening - regularly exceed 24 weeks. Some pins continue driving meaningful traffic 18–24 months after publication. 40% of total pin traffic arrives after day 30, confirming that Pinterest functions as a search engine rather than a feed. For a full breakdown of category-level pin lifespan data, see our Pinterest Pin Lifespan Report 2026.

Unlike YouTube, Pinterest's longevity requires significantly less production effort per piece of content. A static image pin can outperform a video in long-tail traffic, making Pinterest's lifespan advantage accessible to solo creators and small teams without video production resources.

Blog Posts (SEO): 2.03-Year Half-Life

Longitudinal analysis of millions of posts records a blog post half-life of 1,068,305 minutes - approximately 2.03 years. This is the longest half-life of any content format measured, and it is corroborated by independent sources. HubSpot's research on compounding blog posts found that approximately 1 in 10 posts continues accumulating organic traffic for years after publication, growing month over month. Orbit Media Studios' Annual Blogging Survey of 1,000+ content creators similarly shows that keyword-targeted, well-structured posts consistently outperform over multi-year windows. The key driver is Google's domain authority model and search ranking persistence - unlike social feeds, search results don't reset daily.

Blog posts have a half-life of 2.03 years. Pinterest pins 16 weeks. YouTube evergreen videos months to years. The three highest-ROI content types all share one trait: search-based discovery.

Format Breakdown: How Content Type Changes Lifespan

Within the same platform, content format can change lifespan by an order of magnitude. Choosing the right format is one of the highest-leverage decisions a content creator makes.

Content Lifespan by Format Within Platform
Active organic reach window by format type
Content Lifespan by Format, GenSumo Research 2026 Platform Format Active Window Type X / Twitter Tweet (text/image) 15–24 hours Feed TikTok Short video 1–3 hours (viral: days) Algo feed Facebook Post (text/image/video) 5–6 hours Feed Instagram Feed post (image/carousel) 48 hours Feed Instagram Reel 2–4 weeks Explore LinkedIn Post (text/image/video) 1–7 days Network YouTube Evergreen video (SEO) Months–years Search Pinterest Static / video pin 16 weeks median Search Blog SEO article 2+ years Search Sources: Cross-platform engagement research; Sprout Social; HubSpot; GenSumo Research 2026 | gensumo.com/research/social-media-content-lifespan-report/

The pattern is clear: within every platform that offers multiple content formats, the format tied to search or algorithmic redistribution (Reels, YouTube search, Pinterest search) dramatically outperforms feed-native formats on longevity. Content creators who default to feed posts are systematically underinvesting in their highest-ROI formats.

07

The 5 Drivers of Content Longevity

Across all platforms in our dataset, five variables consistently explain the difference between content that decays within hours and content that drives traffic for months.

1
Search-Based Discovery

Search algorithms rank by relevance, not recency. A pin or video published 18 months ago competes equally with one published today if it better matches a query. This single architectural difference explains more of the lifespan gap between platforms than any other factor.

2
Evergreen Topic Focus

Content answering perennial questions retains relevance indefinitely. Content tied to trends or news has a built-in expiry. In our Pinterest dataset, pins in evergreen categories (home decor, recipes, DIY) outlive trend-based pins by 2–3x - and the same holds across YouTube, blogs, and LinkedIn.

3
Keyword Optimisation

Text metadata is the primary signal search algorithms use to match content to queries. Pinterest pins with keyword-rich titles (40–60 characters) receive 67% more impressions in our dataset. YouTube videos with optimised titles and descriptions consistently outrank equivalent content in long-tail search.

4
Engagement Quality Over Quantity

Platforms reward intent signals over raw counts. On Pinterest, saves drive further distribution more than impressions. On YouTube, watch-time completion sustains recommendations longer than views alone. On LinkedIn, comments from second-degree connections extend reach for days beyond initial publishing.

5
Content Freshness Signals

Updating existing content resets relevance signals on many platforms. Blog posts refreshed with new data consistently recover or improve search rankings. Pinterest pins re-saved with updated descriptions re-enter distribution cycles. YouTube videos with updated titles and thumbnails regain algorithmic push. Longevity is not just about initial quality - it is about maintenance.

08

Content Strategy Implications

The lifespan data has direct implications for how marketers and creators should allocate content production effort across platforms.

Goal Best platforms Why
Maximum content ROI (longevity per hour of effort) Pinterest, Blog Highest lifespan relative to production effort
Compounding long-term organic traffic Blog, YouTube (evergreen), Pinterest Search-based ranking persists without re-investment
Real-time reach and news/trend distribution X/Twitter, TikTok Short lifespan, but immediate mass distribution
B2B audience and professional network reach LinkedIn 1–7 day window with second-degree network amplification
Community-building and visual brand awareness Instagram (Reels) 2–4 week Reels lifespan with Explore redistribution
The compound content strategy: The highest-performing content strategies we observe in our dataset combine search-based long-lifespan platforms (Pinterest, blog, YouTube) for compounding organic reach with 1–2 feed-based platforms for real-time audience engagement. Feed-only strategies require constant content production to maintain reach; search-based strategies build an asset base that continues driving traffic without ongoing reinvestment. For Pinterest specifically, our Posting Time Report and Content Mix Report give actionable guidance on maximising that lifespan advantage.

Feed-only content strategies require constant production to maintain the same reach. Search-based strategies build a library that compounds. The platforms with the longest content lifespans are the ones where past effort keeps paying forward.

Frequently Asked Questions

Which social media platform has the longest content lifespan?

SEO-optimised blog posts have the longest half-life at approximately 2.03 years, followed by Pinterest pins (~16 weeks median active lifespan) and YouTube evergreen videos (months to years). X/Twitter has the shortest measured half-life at 49 minutes; TikTok's median post lifespan is under 1 hour, and Snapchat content expires within 24 hours by design.

How long does a tweet or X post last?

An X post has a half-life of approximately 49 minutes. This means half of its total lifetime engagement arrives within 49 minutes of posting. 95% of all engagement ends within 24 hours. In practice, the visible window in most followers' feeds is 15–20 minutes for average accounts.

How long does an Instagram post get traffic?

Instagram feed posts have a half-life of ~18 hours, with most meaningful engagement concentrated in the first 48 hours. Instagram Reels have a significantly longer lifespan - high-performing Reels can surface for 2–4 weeks via the Reels tab and Explore feed, making them the most longevity-efficient Instagram format.

Why does Pinterest content last so much longer than other platforms?

Pinterest operates as a visual search engine. Content is ranked by relevance to search queries, not by recency. A pin published two years ago ranks equally with one published today if it better answers the search query. This makes Pinterest structurally different from feed-based platforms where recency is the primary distribution signal. Our analysis of 173,000+ pins confirms that 40% of total pin traffic arrives after day 30 of publication.
