You send someone to a product through your affiliate link in January. They bookmark the page, think about it, and buy in March. Do you get paid?
Usually not. Most affiliate programs use a fixed attribution window—a clock that starts ticking the moment someone clicks your link. If the purchase happens after that window closes, the commission disappears. No pro-rating, no partial credit, no notification.
If you’re running a content site, newsletter, or course with affiliate revenue, you need to know how long your windows are and what happens when they expire. Here’s what actually determines whether you get paid.
How attribution windows work
When someone clicks your affiliate link, the merchant (or network) drops a cookie or session identifier in their browser. That token tracks two things: which affiliate sent the traffic, and when the click happened.
If the user completes a purchase before the window closes, you get credited. If they return after the window expires—even if they use the same browser—the system treats them as a direct visitor. The sale goes unattributed, or worse, it gets attributed to the last affiliate link they clicked.
Most SaaS and digital-product programs use one of three standard windows:
- 30 days: Common for low-ticket or high-volume products. Examples include MailerLite, Brevo, and many WordPress plugin marketplaces.
- 60 days: Mid-range. Used by tools with longer consideration cycles, like project management or analytics platforms.
- 90 days: Rare, but not unheard of. Some enterprise SaaS and high-ticket course platforms extend this far.
A few programs—usually those with recurring subscriptions—use a hybrid model: a 30-day window for the first purchase, then lifetime commission as long as the customer stays subscribed. Beehiiv and some hosting affiliate programs work this way.
What resets the clock and what doesn’t
Here’s where it gets messy. Attribution windows don’t always behave the way you’d expect.
Clicking your link again resets the timer. If someone clicked your link in January, then clicked it again in February, the window starts over from February. This is why retargeting the same audience—through follow-up emails, retargeting ads, or repeated social posts—can extend your effective window.
Visiting the site directly does not reset it. If they click your link once, then return via bookmark or organic search, the original clock keeps running. The merchant’s system doesn’t know they came back unless they click another tracked link.
Clearing cookies kills the attribution immediately. Most affiliate tracking relies on browser cookies. If the user switches devices, uses incognito mode, or runs a cookie cleaner, the link between your referral and their session disappears. This is more common than most affiliates realize—especially among privacy-conscious audiences.
Why long consideration cycles hurt affiliate revenue
If you’re promoting a $500/year tool or a $2,000 course, your audience isn’t buying on impulse. They’re comparing options, reading reviews, waiting for budget approval, or just procrastinating.
The problem: a 30-day attribution window assumes a fast buying cycle. If your content attracts researchers who take 60 or 90 days to decide, you’ll send plenty of traffic and see weak conversion numbers—not because your audience isn’t buying, but because they’re buying outside your window.
I’ve seen this play out with hosting referrals. Someone reads a performance comparison in October, sets a calendar reminder to migrate in January when their current plan renews, and buys direct. The affiliate who did the research gets nothing.
What you can do about it
You can’t change the attribution window, but you can work around it.
Track your own click timestamps. Use a link shortener or UTM parameters that log to your analytics. Compare your click dates against conversion dates reported by the affiliate network. If you see a pattern—lots of clicks in month one, conversions spiking in month three—you know your window is too short for your audience.
Retarget clickers before the window closes. If you’re promoting a product with a 30-day window, send a follow-up email at day 20. Frame it as a reminder, a case study, or a bonus resource. The goal is to get them to click again and reset the timer.
Focus on products with longer windows or lifetime cookies. If your content naturally attracts slow decision-makers, prioritize affiliate programs that offer 60- or 90-day windows, or those that credit you for the lifetime of the subscription. Postmark and some WordPress hosting programs lean this way.
Build an email list and nurture before promoting. If someone joins your list and you send them an affiliate link six weeks later, the 30-day clock starts fresh. You’re not racing against a window that started when they first discovered you.
One more thing: last-click attribution
Even if your window is still open, you can lose credit if the customer clicks another affiliate’s link before buying. Most programs use last-click attribution, meaning the most recent referrer wins.
This is why you see affiliates aggressively retargeting the same audience, running comparison posts that link to competitors, and sending discount reminders. They’re not just trying to convert—they’re trying to be the last click.
If you want a larger share of your affiliate revenue to stick, treat your links like a checkout flow: keep the path short, reduce the time between click and purchase, and don’t assume a single mention will carry you through a 60-day consideration cycle.
