why listings duplicate

That job you saw 59 times today? It's probably one job.

Why the same job appears dozens of times.
(It's not the employer's fault.)

If you've seen what looks like the same job posted 50 times in the space of a minute, you're not imagining it. And it's usually not who you'd think.

⚠️ TL;DR We traced one senior engineering role that appeared as 59 separate "postings" from a single aggregator, all logged within 25 seconds of each other, all from one postcode. Each had a genuinely unique tracking URL — the signature of syndication fan-out, not 59 real openings. Across the full dataset, 1,756 (advertiser, title) pairs showed 5+ postings landing on the exact same day — 16,341 posting records sitting inside bursts like this.

What's actually happening

Many job boards don't post original listings; they aggregate them from other sources — employer career sites, other boards, ATS feeds. When a distribution platform pushes one vacancy out to many channels at once, each channel can generate its own unique tracking link for what is, underneath, the exact same job.

We saw this directly: a senior engineering role at a well-known employer showed up as 59 separate postings, all logged between 11:39:39 and 11:40:03 — a 24-second window — all tagged to the same single postcode. Sequential aggregator ID numbers a few digits apart. That's exactly what syndication fan-out looks like: one real vacancy, mirrored across dozens of tracking links, not 59 real openings.

🚫 Don't panic-apply to every duplicate

If the same-looking role appears in five places, it's very likely one vacancy. Applying five times won't improve your odds.

🎯 Go to the source

If you can find the employer's own careers page, apply there directly — usually the cleanest route into their real pipeline.

📊 Be skeptical of "huge" numbers

If an advertiser appears to have an enormous number of live postings, check whether it's genuinely that many, or heavily syndicated.

🎯 The bigger picture
Job board data is messier than it looks from the outside. A raw "number of postings" is not the same as "number of real jobs available" — and neither job seekers nor platforms reporting labour market stats should treat it that way without accounting for syndication. Including us, until we account for it.
