Affiliate Cookie Duration Benchmarks by Industry 2026
Compare affiliate cookie duration benchmarks by industry using seven current program examples, from a 24-hour retail session to software and hosting windows.
What Should You Compare Before Choosing?
Affiliate cookie duration benchmarks by industry are useful only when the underlying rules are comparable. A simple 30-day click window is different from a retail session that closes after 24 hours, a shopping-cart exception, or a software program that gives a trial one window and a paid conversion another.
This guide compares seven public program examples checked on October 17, 2026: Amazon Associates, Shopify, Semrush, HubSpot, Hostinger, Kinsta, and SiteGround. It groups them by product type, but it does not claim to measure an industry average. The sample is small, selected for public documentation, and useful for understanding how stated terms differ.
Quick answer
Software examples publish simple windows of 120 to 180 days; hosting examples list 30 to 60. Shopify uses a 30-day click-to-trial stage and a 125-day trial-to-paid stage. Amazon has a 24-hour cart-add session plus a separate rule for items already in the cart. These are examples, not category averages.
| Product type | Program examples | Publicly stated attribution rule | What the sample can tell you |
|---|---|---|---|
| Retail marketplace | Amazon Associates | 24 hours to add items; eligible cart items may qualify later | One retailer example, not a retail benchmark |
| Software and commerce | Shopify, Semrush, HubSpot | 30/125-day stages, 120 days, and 180 days | Staged rules are not one cookie length |
| Web hosting | Hostinger, Kinsta, SiteGround | 30, 60, and 60 days | This set spans 30 to 60 days, not a median |
The Amazon Associates help page explains its session and cart exception. Shopify's official referral-window guide explains its trial stages. Confirm terms in each program account.
How to read affiliate cookie duration benchmarks by industry
A cookie window describes how long a referral can remain eligible after a tracked event. It does not tell you what action qualifies, how a later click changes credit, how returns are handled, or when payment is made. Read it beside the starting and qualifying events.
Here, a single-window claim runs from click to conversion. A staged rule has multiple checkpoints. Amazon's qualifying items must enter the cart within 24 hours, while an item already added may qualify before the cart expires, usually after 90 days. That is not a standard 90-day cookie.
We selected seven programs with a stated duration: one retailer, three software or commerce platforms, and three hosts. This was not random, comprehensive, or a conversion study. The ranges describe these examples only.
Retail marketplace example: Amazon Associates
Amazon's current help page describes a 24-hour session that begins when a visitor arrives through an Associates link. That session can close earlier if the shopper orders or clicks another Associate's link. If a qualifying item goes into the cart during the session, a later purchase can still qualify while the cart remains active, usually for up to 90 days. The precise rule depends on the item and the purchase completing under the program's terms.
Report the event, not just a number of days. Calling Amazon a “90-day cookie” obscures the 24-hour cart-add deadline. Explain the session rule and avoid promising credit outside the qualifying conditions.
Software and commerce-platform examples
Shopify: two windows around a trial
Shopify's official referral guide says the affiliate must be the last eligible affiliate link clicked within the prior 30 days for a free trial to be recorded. After that trial is recorded, a full-price shop must be reached within 125 days for the referral to qualify. The second period starts at the trial event, so it should not be added to the first and described as a flat 155-day cookie. Review the Shopify affiliate program listing and check the current account guidance.
This staged rule fits content that reaches merchants before a trial. Measure qualified trial starts and paid conversions separately because each window answers a different question.
Semrush: a 120-day stated window
Semrush's affiliate page states a 120-day cookie and last-click attribution. Its commission model can vary by product and partner tier, so duration alone is not enough to estimate earnings. The Semrush affiliate program listing is a quick directory reference, while the current application account controls the terms available to an individual partner.
A 120-day stated window may matter when tutorials reach readers early in an SEO buying process. It does not guarantee that every referral remains eligible for the full period. Later clicks and attribution rules can change credit.
HubSpot: a 180-day cookie beside a one-year commission term
HubSpot publishes a 180-day cookie window and 30% monthly recurring commission for up to one year. These describe separate parts of the offer. The cookie window is about referral attribution; the one-year period is about how long a qualifying customer can generate recurring commission. The HubSpot affiliate program listing summarizes the public program terms.
Keep tracking duration and payment duration in separate columns. A longer cookie does not mean a longer commission stream, and recurring payments do not show how long a referral remains attributable before signup.
Web-hosting examples
Hostinger: 30 days
Hostinger's affiliate agreement says its referral cookies are stored for up to 30 days and that a later affiliate cookie can overwrite an earlier one. Its agreement also sets eligibility and commission conditions by product and plan. The Hostinger affiliate program listing is a useful starting point, but read the current agreement for the specific market and channel you plan to use.
A 30-day window can suit readers ready to launch a site. Connect a recommendation to site size, expected traffic, budget, support, and migration needs instead of treating cookie length as the deciding feature.
Kinsta: 60 days
Kinsta's affiliate terms state a 60-day tracking cookie. The terms also say another affiliate link clicked in the same browser can overwrite the original cookie during that period. Find the Kinsta affiliate program listing alongside the current terms when checking the offer.
The two-month window may help readers comparing managed hosting across several visits. Compare performance, support, migration effort, cost, and qualifying plan rules; a longer tracking period alone does not make an offer better.
SiteGround: 60 days
SiteGround's public affiliate page says a referral has 60 days to convert. It also describes a tiered per-sale structure for hosting and separate commissions for some other services. The SiteGround affiliate program listing can help readers find its directory profile before reviewing the live terms.
Separate the standard hosting sale from other SiteGround services. A 60-day duration only matters alongside the qualifying product and commission schedule.
What this sample says, and what it does not
| Group | Examples in this article | Observed pattern | Confidence limit |
|---|---|---|---|
| Retail marketplace | Amazon Associates | One short session with a cart exception | A single program cannot establish a retail average |
| Software and commerce platforms | Shopify, Semrush, HubSpot | Two simple windows at 120 and 180 days, plus Shopify's separate trial checkpoints | The programs use different conversion events |
| Web hosting | Hostinger, Kinsta, SiteGround | The listed public windows are 30 or 60 days | Three selected providers are not a random hosting sample |
The software examples here have longer simple windows than the hosting examples, but this does not prove a category-wide pattern. A reported median should say which programs were counted, how missing terms were handled, and whether staged windows were normalized.
For context, see the affiliate cookie duration explainer, then use the affiliate program research checklist and program comparison guide to record source dates, events, and exceptions.
A practical comparison checklist
Before you compare affiliate cookie duration benchmarks by industry, write down five fields for each offer:
- Start: Click, trial signup, or another event?
- Qualification: Purchase, trial, cart addition, or another action?
- Attribution: First click, last click, or account-level rule?
- Exceptions: Can later clicks, returns, region, or plan rules change credit?
- Payment: When is commission approved, paid, or ended?
Mark unpublished fields unknown and confirm them before forecasting earnings.

FAQ
What is the average affiliate cookie duration by industry?
There is no single average for every program in an industry. A valid average needs a dated sample and consistent qualifying event.
Which industry has the longest affiliate cookie windows?
This sample includes 120-day and 180-day software windows, but does not establish that software programs have the longest windows overall.
Is Amazon's affiliate cookie 90 days?
Amazon describes a 24-hour cart-add session. An item added during it may qualify if purchased before the cart expires, usually after 90 days. This is not a flat 90-day cookie.
Is a longer affiliate cookie always better?
No. Payout rate, qualifying plans, approval, attribution, returns, and audience fit also matter.
