The instinct to always create something new ignores an asymmetry in your own favor: your account today has a different, usually larger, audience than it did when most of your old posts went out — and nearly none of today's followers saw them. A content archive isn't a pile of used material. For most accounts, it's mostly unseen material with a publish date attached.
The math that makes this worth doing
Follower overlap with any single old post is almost always low. If a post went out a year ago to 2,000 followers and you have 6,000 now, at minimum two-thirds of your current audience has a 0% chance of having seen it — they weren't there. Add in the reality that feeds don't show every post to every follower even at the time of posting, and the realistic overlap between "people who saw this the first time" and "people following you today" is usually a small fraction of your current audience, not most of it. The content isn't stale to them. It's new.
What makes a post a candidate, and what disqualifies one
Not every old post qualifies — the audit is about separating evergreen posts from expired ones.
Good candidates:
- Explains a concept, process, or how-to that hasn't changed
- Makes an argument or takes a position that still holds
- Performed well the first time (a signal the idea itself resonates, independent of timing)
- References tools, numbers, or examples that are still current if checked
Disqualified:
- Tied to a specific news cycle, launch, or current event that has since resolved
- References a limited-time offer, discount code, or deadline that has passed
- Cites a stat, price, or product detail that's since changed
- Was reactive to something happening "right now" at the time — it can't be right now again
The test is simple: read the post cold, as if a stranger just found it today. If anything in it assumes a moment in time that has passed, it's expired, not evergreen.
A simple scoring approach
For anything that survives the disqualification pass, score it on three questions:
- Still accurate? Every fact, number, and reference checks out as of today.
- Still relevant? The problem or question it addresses is one your audience still has.
- Performed well originally? Above-average engagement relative to your typical post at the time, not just in absolute terms.
A post that scores yes on all three is a strong repost-verbatim candidate. Two-out-of-three (usually missing "performed well") is still worth resurfacing, just with lower expectations — it might have underperformed the first time because of bad timing, not a bad idea, and a second attempt is close to free to find out.
Refresh vs. repost verbatim
If a post is a "yes" on accuracy and relevance but has one stale detail — an old screenshot, a stat that's moved, a reference to a since-changed feature — refresh it rather than reposting as-is: swap the one stale element, keep everything else, republish. If it's fully accurate and it's just been a while, repost verbatim; there's no benefit to rewriting something that already worked, and rewriting introduces a chance of making it worse.
Building this into a routine
Treat the audit as a recurring pass rather than a one-time cleanup: once a month, pull your top 10-15 posts by original engagement from more than six months back, run them through the scoring questions above, and queue whatever survives. This pairs naturally with the same pillar-and-derivatives thinking in our content repurposing guide — a strong old pillar can even be re-derived into fresh carousels or quote cards using the video-to-carousel or testimonial methods, not just reposted as-is. Either way, the archive you already have is very likely underused, not exhausted.
