The essentials
- Evergreen: content that stays true and useful for months (an answer to a customer question, a method, a comparison); it can be reposted and feeds the platforms' internal search.
- Trending: content tied to a moment (a viral format, a news item, a trending sound); strong but short reach, useful for reaching beyond your followers.
- 2026 split: 60 to 70% evergreen, 20 to 30% trending, 10% company news; the reverse exhausts the team and the audience.
- Shelf life: a few hours on X, one to two days on Facebook and LinkedIn, several weeks on TikTok and YouTube where search extends distribution.
Evergreen content keeps its value for a long time: the answer to a question your customers ask every week, a method, a comparison, a mistake to avoid. Trending content exploits a moment: a format doing the rounds, a news item, a sound or a meme, an event. Both have their place in a social strategy; the problem comes from the proportion and from what is expected of each. This page gives the definitions, the real shelf life by network, the split that holds over time and the method for recycling.
Two different logics of reach
| Criterion | Evergreen content | Trending content |
|---|---|---|
| Main objective | Consideration, trust, saves, search | Awareness, reach beyond followers, new followers |
| Reach peak | Moderate, steady | Strong if the timing is right, nil if it is missed |
| Distribution period | Long: TikTok, YouTube and Pinterest search, reposts | Short: 24 to 72 hours |
| Cost of production | Higher (substance, fact-checking), amortised by recycling | Low, but demands responsiveness |
| Risk | Poor | Off-topic, out of step with the brand, trend already over |
| Signal sent to the audience | Expertise, seriousness | Closeness, responsiveness, humour |
The platforms themselves have changed: TikTok, YouTube and Instagram increasingly work like search engines, which extends the life of evergreen content that is well titled and described. How this distribution works is detailed in the social media algorithm.
Real shelf life by network
The shelf life of a post is the period during which it still receives a significant share of its reach. Orders of magnitude for 2026:
- X: a few hours; all content there is effectively « trending ».
- Facebook: 24 to 48 hours for the feed; Reels can be redistributed for longer.
- LinkedIn: 24 to 72 hours, more if comments restart distribution.
- Instagram: 24 to 48 hours for the feed, several days to several weeks for a well-received Reel.
- TikTok: several days to several months; internal search gives old videos views again.
- YouTube: months to years for a well-optimised long-form video; a few days to a few weeks for a Short.
- Pinterest: months; the network most favourable to evergreen.
Practical consequence: evergreen is all the more worthwhile when the network has a search component. On YouTube and TikTok, take care with the title, the description and the spoken keywords; on LinkedIn and Facebook, plan to repost.
The split that holds over time
The recommended split for an SME in 2026: 60 to 70% evergreen, 20 to 30% trending, the rest company news (recruitment, events, offers). This proportion is thought through by the month, in the editorial calendar, with content pillars that guarantee the evergreen share. Two frequent drifts:
- All trending: the team chases formats, reach is erratic, new followers do not match the target audience and nothing lasts. This is the drift of accounts that measure their success in views.
- All evergreen: the account is solid but grows slowly; reach stays confined to followers and searches. This is the drift of B2B accounts that do not dare.
A trend is only worth using if it can carry your message: repurpose the format, keep the substance. An accountant who uses a trending format to explain a tax deadline is doing trending content; an accountant who dances is doing nothing.
Producing and recycling evergreen
Evergreen is built from customer questions. A list of 30 real questions gives six months of substantial content. Each question becomes a main format (a 45-second video or a carousel), then is adapted: an extract in a story, a quote as a visual, a text version on LinkedIn, a question as a poll. Adapting across networks is detailed in managing several social networks without burning out. Recycling follows a simple rule: an evergreen post that has exceeded 1.5 times the account's median engagement is reposted, in a slightly modified form (new hook, new visual, new format), 60 to 90 days later. Fewer than 10% of the audience saw it the first time.
| Original format | Evergreen adaptations | Repost interval |
|---|---|---|
| Short educational video | Carousel of key points, quote as an image, LinkedIn text, extract in a story | 60 to 90 days |
| Comparison carousel | Piece to camera, table as a single image, poll | 90 days |
| Customer testimonial | 15-second extract, verbatim quote as a visual, « before / after » post | 90 to 120 days |
| Article on the site | A series of three videos, a carousel, questions and answers in the comments | Each time the article is updated |
Measuring each with the right metric
Judging trending content on saves, or evergreen content on views at 48 hours, leads you to abandon what works. For trending: reach beyond followers, new followers, shares, views at 3 days. For evergreen: saves, comments, clicks, cumulative views at 30 and 90 days, profile visits and, on TikTok and YouTube, the share of views coming from search. These metrics belong in the dashboard described in the reference SMO KPIs, with an « evergreen » or « trending » label on each post so the two families can be compared at three months.

Frequently asked questions
What is evergreen content on social media?
Content that stays true and useful for months: an answer to a common question, a method, a comparison, a mistake to avoid, a definition. It depends neither on the news nor on a fashionable format, is found through platform search and can be reposted in another form without losing value.
Should you follow trends as an SME or a B2B business?
Yes, sparingly: 20 to 30% of posts, provided the trend serves your message and stays compatible with your tone. A well-repurposed trend reaches people beyond your followers; a trend followed for its own sake attracts an audience unrelated to your customers and tires the team.
How long does a post stay visible?
A few hours on X, 24 to 48 hours on Facebook and Instagram for the feed, 24 to 72 hours on LinkedIn, several weeks to several months on TikTok, YouTube and Pinterest thanks to search. These durations justify reposting evergreen content on networks with a short shelf life.
Can you repost content that has already been published?
Yes, and it is even recommended for evergreen content that performed well: fewer than 10% of the audience saw it the first time. Wait 60 to 90 days, change the hook, the visual or the format, and avoid the exact copy that some platforms distribute less well.
