Why do I see the same job on so many websites?

Employers and recruiters often publish one role to several job boards at once, and aggregator sites copy listings from those boards. Each copy shows its own date and layout, so one opening can look like five separate jobs. The original usually sits on the employer's own careers page.

Should I apply to the same job on every site?

No. Applying more than once for the same role can look careless and splits your effort. Find the employer's own listing, apply there once, and keep a note of the link and date. If the role only appears on a board, apply through that one.

How can I tell if a job posting is still open?

Check the employer's careers page first, because it tends to be updated soonest. Look at the update date rather than the original post date, and see whether the apply link still works. If the role is gone from the employer's page but still on boards, it may have closed.

What is an employer-direct job listing?

It is a listing read straight from the employer's own hiring system or careers page, not copied from a job board. The apply link belongs to the employer, and there are usually fewer duplicates. It can miss roles that employers publish only on boards. Job Opportunities API, built by the same studio as Kaeros, works this way.

Why the Same Job Appears on Five Sites (and Which to Trust)

You search for a "Marketing Coordinator" role at one company and find it on a big professional network, a general job board, a local site, an aggregator and a company page. Five tabs. Same title, same company, slightly different dates. It is natural to wonder: is that five jobs, or one?

Almost always, it is one. The same job posted on multiple sites is not a sign that you are missing something, or that the company is desperate. It is how job listings travel. Once you see the plumbing, you can use it to save time, apply to the right place and write a better CV for the role.

How one job becomes five

A typical journey looks like this.

The employer creates the role. Usually in a hiring system called an applicant tracking system (ATS), and often as a page on the company's own careers site.
The ATS or a recruiter sends it onward. Many hiring tools can publish a role to several job boards with one click. That gives the board its own copy of the listing.
Aggregators collect from boards. Some sites exist only to gather listings from many places into one search. They copy what the boards show.
Agencies and recruiters repost. A staffing agency may advertise the same role under its own name, sometimes without naming the employer.
Every copy gets its own date. A board may show the day it received the listing, another the day it refreshed it, and a third the day it noticed it. That is why "posted 3 days ago" and "posted 3 weeks ago" can describe the same job.

So five listings do not mean five openings. They mean one opening, copied four times.

What this costs you

Duplicates are annoying, but the bigger costs are quieter.

Time. You scroll the same role again and again, or apply twice through different doors.
Dead ends. A copy can stay online after the employer has filled or closed the role. You apply, hear nothing, and wonder what you did wrong. Usually the answer is: nothing. The listing was already stale. Our guide on how to spot ghost job postings explains what to look for.
Missing details. Each copy may drop part of the description, the salary or the apply instructions that the original had.
Hidden employers. Some agency listings do not name the company, so you cannot research who you would work for.

None of this is your fault. It comes from how the system is built, not from how you search.

How to find the original listing

You can usually get to the source in a few minutes.

Search the company's name and the exact job title. Add "careers" to the search.
Open the employer's own careers page and look for the role there. Companies tend to keep this list closest to the truth.
Check where the "Apply" button leads. If it goes to the employer's hiring system, you are in the right place. If it goes to another board, you are on a copy.
Compare dates and wording. If one version has a fuller description or a newer update date, that is probably nearer the source.
Notice who is posting. If the company name is missing or generic, it may be an agency listing. Look for the same role on the employer's page.
Save the employer's link, not the board's. It is the one that tells you the role is still open when you return to it.

If the role is not on the employer's careers page at all, treat that as information, not proof. It can be new, internal, or already filled. For more on this, see our comparison of LinkedIn Easy Apply and applying on the company website.

Where employer-direct job data comes in

Behind many job sites there are data services that supply the listings. Some copy them from other boards. Others read them straight from the employer's hiring system or careers page. We call that last kind employer-direct data.

Employer-direct data changes the picture in three ways. There are fewer duplicates, because each role is read once at its source. The apply link belongs to the employer. And a good service notices when a role has been taken down, so a closed job does not keep looking open.

It is not perfect. Employers that do not publish on a public hiring system, or that post only on boards, will not show up. And no service can tell you whether a company will actually hire.

One example is Job Opportunities API (JOA), which is the source we would point you to if you want the employer's own listing first. It collects postings from employers' hiring systems, careers pages and public employment services, keeps roles that have closed with a closure date, and sends you to the page where the employer takes applications. We are open about the connection: JOA is built by the same small studio as Kaeros, so weigh this recommendation with that in mind. You can browse its listings at jobopportunitiesapi.org/jobs. It will not have every role, because some employers post only on boards, so treat it as another tool next to your usual searches, not a replacement for them.

Make the duplicates work for you

Once you know why a job repeats, the repetition becomes useful.

Wide distribution can mean active hiring. A role sent to many boards at once often means the employer wants a lot of applicants quickly. It does not guarantee a response, but it suggests the role is not a quiet internal formality.
Very old copies are a warning, not a verdict. If a listing has been online for months with no change, ask whether the employer still shows it on their own page before you invest an evening in it.
Different copies can fill in each other's gaps. One may show the salary range, another the team, a third the exact location. Gather what you need, then apply through the original.

It also helps to keep a short record of what you have applied to: the company, the exact title, the link to the employer's own page and the date. A simple spreadsheet works. If you would rather not maintain one, there are tools built for it; Erioun, which is built by the same studio as Kaeros, is one of them. The point is the same either way: with five copies of every job, a written note stops you from applying twice and tells you when it is time to follow up.

What this means for your CV

The original listing is the best text to write your CV against. Boards sometimes shorten descriptions, and the full employer text shows the exact skills, tools and wording the hiring team uses. Compare it with your CV and mirror the relevant phrases, honestly and only where they are true for you. Our ATS-friendly CV guide shows how to do that without keyword stuffing.

A role that appears on five sites is still one role. Put your energy into one strong application, sent through the employer's own door, with a CV written for that exact listing.
