Someone clicks your link today but buys next week. Do you get credit? It depends on the attribution window.
The basic idea
When a visitor clicks your link, a timer starts. If they complete the qualifying action before the timer runs out, the conversion can be credited to you. If they act after the window closes, it will not be.
Different campaigns use different windows: some short, some much longer. The window is set by the advertiser and published in the campaign terms.
Last click usually wins
Most affiliate programs use last-click attribution. If a shopper clicks your link, then a week later clicks another publisher’s link and buys, the second click usually gets credit. That is why being close to the moment of decision matters.
Why windows differ
| Purchase type | Typical decision time | Why the window matters |
|---|---|---|
| Impulse deals | Minutes to hours | A short window is fine |
| Fashion and beauty | Hours to days | Moderate window |
| Electronics | Days to weeks | Shoppers compare prices |
| Travel | Days to weeks | People plan ahead |
| Finance products | Days or more | KYC and paperwork take time |
How browsers and apps affect it
Attribution depends on the click information surviving until conversion. Privacy settings, ad blockers, cleared cookies, switching devices or moving from a browser to an app can break that link. Advertisers use different methods to reduce this, but no method is perfect. See how affiliate tracking links work.
Planning content around the window
- For short windows, post when your audience is ready to act: during sales, launches or price drops.
- For long windows, invest in comparisons and guides that people read while deciding.
- Remind, do not repeat blindly. A reminder near the end of a sale can bring people back through your link.
- Put your link near the decision. A link in a comparison table is more useful than one at the bottom of a long post.
Attribution window vs validation period
These are different:
- The attribution window decides whether a conversion is credited to your click.
- The validation period is how long the advertiser takes to confirm the conversion is genuine after it happens.
A conversion must happen inside the attribution window, then survive validation, before it becomes approved earnings. See conversion validation explained.
Key takeaway
Know each campaign’s window, be present when your audience decides, and remember that the last eligible click usually wins.
Frequently asked questions
Where can I find a campaign’s attribution window?
It is part of the campaign terms. On M2E, each campaign shows its tracking period before you join.
What if the customer clicks two different affiliates’ links?
Most programs use last-click attribution, so the most recent eligible click usually gets the credit.
Does a longer window always mean more earnings?
Not necessarily. It helps for considered purchases, but campaign fit and conversion rate matter more.
