Quick Answer
CJ (Commission Junction) is one of the longest-running affiliate networks — a marketplace where your brand (the advertiser) connects with publishers who promote you in exchange for commission on the sales they drive. You join as an advertiser, install CJ's tracking on your site, set your commission terms, and then recruit and approve publishers from inside the dashboard. Once tracking is live and partners are active, CJ records the clicks and sales and handles paying your publishers for you.
What it is
CJ (Commission Junction) is an affiliate network — think of it as a managed marketplace that sits between your brand and the thousands of websites, creators, and content publishers who might want to send you customers. You don't pay them directly or chase invoices; CJ tracks who drove each sale, calculates the commission, and pays everyone out of the funds you deposit. Founded back in 1998, it's one of the oldest and largest networks around, which means it has a deep, mature base of established publishers.
Here's an everyday analogy. Imagine you run a shop and you want a small army of recommenders out in the world sending shoppers your way. Instead of hiring each one, signing contracts, and tracking who sent whom on a spreadsheet, you join a kind of agency. The agency hands every recommender a coded business card, watches the front door to see whose card a customer arrived with, and at the end of the month tells you exactly who to thank — and pays them on your behalf. CJ is that agency, just for the web.
Why it matters
If you're launching or taking over an affiliate programme, the network you run it on shapes almost everything: which publishers you can reach, what your tracking looks like, how you pay, and how much manual work lands on your desk. CJ matters because it carries serious weight with the established affiliate community — coupon and loyalty sites, content publishers, and large media partners have CJ accounts already and are comfortable working inside it. That existing footprint means you're not starting from a cold, empty room.
It also matters because CJ is a more "enterprise" platform than some of the lighter-touch networks. There's real reporting depth, granular commission rules, and tooling built for brands that take affiliate seriously. The flip side is that it expects you to know what you're doing — which is exactly why a beginner's orientation like this is worth reading before you start clicking buttons.
How it works
From your side as the advertiser (the brand running the programme), getting going on CJ looks roughly like this:
- Sign up as an advertiser and get approved. CJ vets advertisers, so you'll provide business details, your website, and a sense of the programme you want to run. This isn't an instant self-serve signup — expect an onboarding step before your account goes live.
- Install the tracking. CJ gives you a snippet of conversion tracking (often a tag or container) that fires on your order-confirmation page and reports the sale amount and order ID back to the network. Nothing works until this is firing correctly, so this is the step to get right.
- Set your commission terms. Decide what you'll pay — a percentage of each sale, a flat fee per action, or different rates for different product groups or customer types (new versus returning). These rules live in your account and CJ applies them automatically.
- Build your programme terms and creative. Write the agreement publishers see when they apply (the "offer"), upload banners and text links, and set the cookie window that decides how long after a click a sale still counts.
- Recruit and approve publishers. Use CJ's publisher marketplace and recruitment tools to find partners, then approve the ones that fit. You control who joins — you can auto-approve or review every application by hand.
- Fund your account. CJ pays your publishers from a balance you top up, plus its network fee. Keep this funded or payouts (and your standing with partners) will stall.
- Monitor, optimise, and pay. Watch the dashboard, validate or correct transactions during your review window, and let CJ handle the actual publisher payments on schedule.
Common mistakes
- Treating tracking as a "set and forget" step. A mis-fired or duplicated conversion tag is the single most common cause of dramas — publishers either go unpaid (and leave) or get paid twice (and your costs blow up). Test a real order end to end before you invite anyone.
- Launching with no recruitment plan. Joining CJ doesn't make publishers appear. The network gives you reach, but you still have to actively find, pitch, and approve the partners you want. Brands that "go live" and wait usually see nothing happen.
- Approving every publisher who applies. Some applicants add real value; others are low-quality or sit on brand-bidding and trademark terms you don't want. Set clear approval criteria up front rather than rubber-stamping everyone.
- Ignoring the transaction review window. CJ gives you time to validate or reverse transactions (for returns, fraud, or test orders) before they lock. Skip this and you'll pay commission on cancelled or fraudulent sales you could have caught.
Reporting tips
The CJ dashboard can feel busy at first, so start narrow. Pull a performance report by publisher and sort by sales — this immediately shows you the handful of partners actually driving revenue versus the long tail doing very little. As a beginner, resist the urge to read every metric; clicks, orders, sales amount, and earnings-per-click (EPC) will tell you most of what you need in the early weeks.
Watch your new-versus-returning customer split if you've set that up, because it answers the question every finance team asks: "are we paying commission on customers we'd have got anyway?" Also keep an eye on individual publisher trends over time rather than single days — a partner whose orders suddenly spike overnight is worth a closer look, since it can signal anything from a genuine campaign to coupon leakage or trademark bidding. Schedule a regular report to your inbox so monitoring becomes a habit, not something you remember once a month.
When to use / when not to use
| CJ is a strong fit when… | Think twice when… |
| You want access to a deep, established base of professional publishers from day one. | You're a tiny brand wanting the lightest, cheapest possible setup with minimal admin. |
| You need enterprise-grade reporting, granular commission rules, and serious tooling. | You don't have the time or a manager to actively recruit and vet publishers. |
| You can fund the account and absorb network fees as part of your cost of sale. | Your tracking can't yet reliably fire a clean conversion tag — sort that first. |

Frequently asked questions
How long does it take to get started on CJ as a new advertiser?
Plan for days, not minutes. Advertiser accounts are reviewed and onboarded rather than instantly self-served, and then you still need to install and test your tracking, write your programme terms, and upload creative. Most brands are realistically a week or two from sign-up to a programme that's genuinely ready to recruit into, especially if a developer has to add the conversion tag.
Do I need a developer to set up CJ tracking?
Usually yes, at least briefly. CJ's conversion tracking has to fire on your order-confirmation page and pass back values like the sale amount and order ID. If you're on a platform with a CJ integration or a tag manager you're comfortable with, a non-technical manager can sometimes handle it — but for a clean, tested setup, having a developer place and verify the tag is the safest route.
How much does it cost to run a programme on CJ?
There are three layers: the commission you pay publishers, a network fee CJ charges on top of that activity, and often a deposit or minimum to keep the account funded. Treat all of it as a cost of sale and model it before you launch, because the network fee is easy to forget when you're focused on commission rates. Get current figures directly from CJ during onboarding, as terms vary by account.
