The 90 Day Amazon Affiliate Cookie - Frequently Asked Questions - AuthorityAzon

The 90 Day Amazon Affiliate Cookie – Frequently Asked Questions

I’ve seen a lot of differing opinions on the 90 day Amazon cookie over the past couple of years, and what’s worse, I’ve also seen a lot of different information.

This isn’t surprising, considering that the Amazon Operating Agreement isn’t particularly conclusive about exactly how the cookie works. It also doesn’t cover every possible scenario for using this cookie either, which leads to more information.

amazon 90 day cookie

For today’s post, I’ve imagined several different scenarios, and based on what I could find in section 7 of the operating agreement, and additionally, based on what I could get out of the Amazon reps in live chat, I’ve posted my conclusions below.

Generally speaking, the 90-day cookie IS better than the 24-hour cookie, but it’s not as black and white as that, and you should decide whether or not to use it based on your own site’s situation.

What Is The 90-Day Cookie?

Let’s step back a bit, for those of you who didn’t know, and talk about the 24 hour cookie and the 90 day extension of it.

Standard 24-hour Cookie

The standard Amazon affiliate link gives you 24 hours for a customer to make a purchase, in order for you to earn a commission.

This means that if a customer clicks your link and orders ANYTHING (almost anything), within a 24 hour window, you’ll earn a commission on those items. It’s a universal cookie, meaning that even if the customer clicks through your link to view a baby stroller, but ends up buying a new kitchen set, some dumbbells, and a ribbon for their dog, you’ll get paid for all of those items.

Based on my own experiences, 30-40% of my affiliate commissions come from products that I didn’t specifically link the customer to, and another 30% come from related products they bought on top of the one I did recommend. So without the universal cookie, my commissions would be a lot lower.

Little-known fact: As soon as the customer places an order, your cookie is wiped. Even if they come back 1 hour later and order more things, you won’t get paid.

90 Day Cookie

Sometimes though, a customer doesn’t immediately order a product, especially if it’s a high-ticket item. To make up for this, Amazon will extend your cookie by another 89 days if the customer adds a product to their cart. In other words, if they add it to the cart and then leave Amazon, you’ve got 89 more days to hope they come back and finish checking out.

This is obviously a huge difference.

However, I don’t believe it’s always best to send customers straight to the add to cart button, otherwise, Amazon would make these standard.

Myths About The 90 Day Cookie

While the 90 day cookie is great, there are a lot of myths that I’ve seen about it, even from some people selling products that utilize it.

Here’s the first myth: The only way to get the 90 day cookie is to use a special add to cart button.

A lot of Amazon plugins and themes exist that claim the only way  to get a 90-day cookie is to use a special plugin or theme (usually theirs). This is simply not true.

If ANY customer visits Amazon through ANY special link and adds a product to their cart, you get an 89 day extension. This means that the normal Amazon links you are already using can still earn you a 90 day cookie, and you’ve likely already had it happen.

The difference here is that those themes and plugins make it easier to get a special “add to cart” link, which prompts users to add the product to their cart, and increases the chances of a 90 day cookie.

Another myth: You can only get “add to cart” links by using the API or special plugins and themes.

Again, this is not true. You can use the following code to make an add to cart link of your own:

Replace “storeid-20” with your Associates ID and “B00003CWT6” with the ASIN of the Amazon product you wish to promote. If you are a Product Advertising API subscriber, you should also replace the Subscription ID.

<form method=”GET” action=””> <input type=”hidden” name=”AssociateTag” value=”storeid-20″/> <input type=”hidden” name=”SubscriptionId” value=”[AWSAccessKeyId]”/> <input type=”hidden” name=”ASIN.1″ value=”B00003CWT6″/><br/> <input type=”hidden” name=”Quantity.1″ value=”1″/><br/> <input type=”image” name=”add” value=”Buy from” border=”0″ alt=”Buy from” src=””> </form>

Third myth: The 90 day cookie is a cookie

It’s not actually a cookie, it’s an extension of the qualifying purchase period. A cookie is something which sits in a customer’s browser and earns you a commission when they make a purchase. The 90 day “cookie” doesn’t work this way. Basically, if a customer adds something to their cart, then once the cookie has expired (24 hours after they first clicked your link), you still have 89 days for them to complete their purchase before you earn a commission.

This means that even if they return to Amazon from a different browser or device, and complete their checkout, you still get the commission.

This also means that if they come back to Amazon via somebody else’s link, you still get the commission.

However, what this DOESN’T mean is that if the customer adds a product to their cart, you now have a 90 day cookie and can earn on anything else they buy in the next 90 days.

Fourth myth: You get a commission for anything in the customer’s cart at the time of checkout.

Here’s where it gets confusing, and sales pages of various plugins and themes get misleading. Many people say that you get paid for the WHOLE cart at the time of checkout, whereas in fact you don’t. You only get paid for the products initially added to the cart.

Here’s the scenario:

A customer visits Amazon after clicking your link, adds 3 products to their cart, then leaves Amazon. Less than 89 days later, they return to Amazon, add 5 more products to their cart, and check out all 8 items.

You only get paid for the 3 that they initially added within the 24 hour window. This is still pretty cool, but it’s not how a lot of people portray it.

Remember, it’s not a cookie, it’s just an 89 day extension of THOSE products. If it worked how some people said it did, then customers would indefinitely extend the 90 day period forever by continuously adding things to their cart and coming back later.

Other Things To Consider

While you would think on the surface level, that the 90 day “cookie” results in higher commissions, it’s not necessarily true. You have to think about conversion rates and customer behavior.

For example, when you send a customer to the “add to cart” page, they’ll see an uninspiring blank page with the question, “do you want to add this to your cart?” and the name of the product.

None of the things that they’d expect to see, such as product information, reviews, related products and pricing will be visible.

There’s a strong chance that they’ll just close the tab and leave, whereas sending them to the product page via a normal affiliate link could have resulted in a sale, or multiple sales. It’s pretty clear that some customers will find this move deceptive, and the disconnect between your review article and them being prompted to add something to cart could have the opposite effect.

In this case, chasing the 90-day cookie would have been a bad move.

Additionally, Amazon is well known for its ability to convert people, having investing billions of dollars in this very process, so for many situations, the normal affiliate link will do the job just fine.

How To Decide

As well as testing your links to see what results in higher conversions, it’s well worth considering your customer buying habits. Are you promoting low-priced ($50-100) items that customers might buy on an impulse? If so, the 90-day cookie is probably not worth going for, especially as you might lose sales due to the above mentioned disconnect.

On the other hand, if you are promoting more expensive items, like TV’s or luxury items, it might be better to try and use the add-to-cart prompt, as people are less likely to buy straight away.

You should always be trying to test your links and call to action buttons anyway, so this is something to add to your test list.

Of course, if your Amazon site is setup like an eCommerce site, where customers can add items to a cart on your store, before going to Amazon to checkout, then I would say this is an instance where you ALWAYS want to use the 90 day add to cart feature. It’s only affiliate sites where you need to weigh up the pros and cons.

Final Thoughts: The Pros And Cons Of The 90 Day Cookie

Generally, there are more pros than cons, but it’s far from a no-brainer decision. In a niche where people buy lots of items based on quick decisions, trying to force people to add items to their cart immediately might result in less conversions, not more.

In a higher ticket niche though, you may well pick up more sales as a result of doing this, and the few customers who get put off by the add to cart prompt may well be offset by the increased number of customers returning later to complete their purchase.

Remember though that the “add to cart” link still works the same as a normal affiliate link, so if they don’t immediately add the product to their cart, but shop around and make a purchase within 24 hours, you do still get paid.

The most important thing for you to do is be aware of how exactly the cookie works, and then plan your promotions around that. Additionally, make sure you are testing the different link types and tracking the outcome on your conversions and profit.

The Million Dollar Question

Are we going to add the ability to make “Add to cart” links to the AuthorityAzon theme? We’re considering it. It’s very much possible to add this function to the theme, but right now we are hoping to gauge demand first.

So let us know in the comments below if this is something you’d like to see.

In the meantime, you can use the code above to add this function to any WordPress site, including AuthorityAzon-powered ones.

Great post, never realised that it was just an extension.

I used to have 1 product that I promoted that I used an add to cart option because it was a very focused product.

However I recently disabled that option and just left it as a normal 24 hour cookie option and have seen an increase in my conversation rate.

Now I can’t be 100% sure that this is a result of disabling the add to cart option,but the conversation rate significantly increased in just 1 month so it is a possibility.

    Rupert Birkes - 3 years ago

    Did you know that you can get a 90 day cookie when you send someone to Amazon through your affiliate link?  When you use a regular affiliate link, the cookie is just 24 hours.

      authorityazon - 3 years ago

      Nope, there’s no 90 day cookie from any amazon link, you didn’t read the article it seems 🙂

        celeste bradley - a couple of years ago

        I’m confused. How do I enable the 90 day cookie?

          authorityazon - a couple of years ago

          You don’t, that’s the point. It’s not something you enable.

    Marvel Gladwell - last year

    Oooh that’s super helpful, thank you for sharing.

    Tora Huffstickler - last year

    Thanks for sharing this information..have shared this link with others keep posting such information..

Brendan Monahan - 3 years ago

Thanks for putting up the post guys! It answered all the questions I had and some I didn’t know to ask yet. I just started sending customers to a $500 product via the usual product link (not add to cart). Any idea on the type of conversion ratio I can expect?

    authorityazon - 3 years ago

    Not really, it’s always different depending on the niche.

Shakti Kumar Jain - 3 years ago

This is a good and informative article about Amazon Affiliate Cookie 24 hours vs. 90days. But this should be made more clear if all the affiliate cookies are 90 days cookies or some special functionality is provided through the plugins.

Dan - 3 years ago

We are using 24 hour window for our site. But we are getting 90 days cookies from Amazon. For example, we don’t have traffic one day but still we received sales on our affiliate account. Can you clarify.

Marc - 3 years ago

Is there a section in the TOS that talks about add to cart links? Like on high priced items, are you allowed to have a link that says ‘add to cart to see best price?’

i would guess not but just curious.


    authorityazon - 3 years ago

    I’d recommend you ask Amazon yourself about that as it’s not really clear

Paul - 3 years ago

Great post. I’ve been bombarded with emails from amazon developers telling me there is no way to get the 89 day cookie unless I purchase their plugin or script! Obviously there is and your post does a good job of explaining how it works. I had to read it several times but I did have that “ah-ha” moment once it set in!

Is there a way to tell if previous purchases were made within the 24 hr. or 89 day period?

    authorityazon - 3 years ago

    I don’t think so, that would be really useful though.

    Ken - last year

    Late reply here- but you can always test by adding a new tracking ID only for adding to the cart.

Angela - 3 years ago

Thank you for listing the Amazon 90-day cookie myths. I was just about to purchase a plugin which promises to extend the cookie to 90 days but I decided to search around for more reviews. Good thing I found your post. I guess one can only hope that the customer adds to cart as many items as possible and have them buy everything on the cart within the 90-day period! 🙂

jumbo - 3 years ago

I got a question. if somebody visited through my special link to a product i recommend and didn’t placed an order,leaves and within 24 hour frame they visited through special link of another website with same product that i recommend, who’ll get paid?

    authorityazon - 3 years ago

    The second site would get paid, but this is pretty rare.

      jumbo - 3 years ago

      Thanks!. Got one last question not related to cookie but its better to open special links in new tab/window?
      Also thanks for the 90 day cookie extension tip which i didn’t know can be used without plugins!

Kurt Perschke - 3 years ago

hi, if I do get the authority azon theme can I use the method above to manually create the 90 day links, in order to test side by side for my products?


    authorityazon - 3 years ago

    Yep you can!

Eve - a couple of years ago

Informative post. Thanks for sharing.

Here’s a question for you: Do amazon affiliate links ever expire? What I mean by this, is once I have a shortened link (or image link or whatever), will I ever need to change/generate a new one in the future (like 6-12 months after)? I imagine you wouldn’t need to do this, but i’d like to be sure. What are your thoughts? Cheers!

    authorityazon - a couple of years ago

    No, as long as the product is still available it’s fine.

Noe - a couple of years ago

Question, if someone adds a product to a wishlist instead the cart, does it still work the same way as adding a product to the cart with the 24 hour or 90 day “cookie”?

    authorityazon - a couple of years ago

    Not 100% sure on that actually.

Kevin - a couple of years ago

Great post I learned a lot about 90 days cookies .I hope to use this to my advantage in the future .

KP - a couple of years ago

Thanks – great read and insightful about the pros and cons of the 90 day extension

Rob martin - a couple of years ago

Nice article indeed, but if I want to share my affiliate link via articles or blog posts then I have to refresh that link in every 24 hours?

    authorityazon - a couple of years ago

    No, the 24 hours starts when someone clicks the link, not when you post the link.

      Hector - 11 months ago

      Hello I have a similar question. What about when people click on my website affiliate links, but don’t buy, do I have to update the link after 24 hour have passed in order to earn commission?

Johnny Lung - a couple of years ago

Awesome post. I have a question: Is it possible to create just a link that adds the 90-day cookie? I don’t want to add the button.

    authorityazon - a couple of years ago

    Sure but it needs to use the correct HTML

krish - a couple of years ago

i am using Woozone Plugin. It have 90 day cookies extension feature. Here my doubt is how we can know, Is 90 day cookies working or not ?
Advance thanks for your replying bro.

    authorityazon - a couple of years ago

    It’s only a 90 day cookie if they add something to their cart.

Nate Munk - a couple of years ago

Do you know if this applies to the add to registry function too or just the add to cart?

    authorityazon - a couple of years ago

    Only if they add to cart.

Kyle - a couple of years ago

If someone clicks on the link then leaves Amazon but comes back within the 24 hours and buys something do i still get the commission?

    authorityazon - a couple of years ago

    Yeah you do.

MD - a couple of years ago

Thanks for the Great post.
I have a confusion about the amazon affiliate order report Clicks & Conversion Summary section it says Numbers of “Direct-Link Clicks” and “Other Clicks”.

Since my blog don’t get much traffic but my Facebook fan page has better traffic so i started to focus on that and only posting my amazon affiliate links staight to my Facebook page.

Which is type of click is better for me if i promote links straight in to my Facebook what is the difference between “Direct-Link Clicks” and “Other Clicks” .

Thank you

Tom - a couple of years ago

Thank you for clarifying this.

Did I understand it right that the lifespan of the cookie is basically something the issuer can define? So there are other sites around which are fine with 15 day cookies, or even longer, but amazon has the policy to go with a 24h definition?

    authorityazon - a couple of years ago

    That’s correct.

      Alejandro - a couple of months ago

      Hey there. I know I’m a bit late to the party, but I’d like to know something particular:

      How do you even know when a cookie is set (can you find out through the browser inspector as you would with normal cookies?).

      You see, I’m a developer and I have little knowledge on how the Amazon cookie really works or how to spot it, how is it called, but I’d be very interested in it, because I have a nice project for a tool in mind that could help users test if the cookie is set or not.

      Thanks in advance, every information you can give me helps @authorityazon 😀

Birgitt - a couple of years ago

How to set a cookie for anything added to the cart? Is there a way for that?

Kristi Ambrose - a couple of years ago

Glad to see someone being honest.

“If ANY customer visits Amazon through ANY special link and adds a product to their cart, you get an 89 day extension. This means that the normal Amazon links you are already using can still earn you a 90 day cookie, and you’ve likely already had it happen.”

Also, I HAVE been to many many many websites and you are right, they all say that you simply cannot do the 90 cookie without THEIR help. I hate when websites do this – information that is controlled and made up because, for the normal person that just reads the website, they think oh okay, I guess I will just lose out. For me? I search until I find an absolutely definitive answer. Which I found here. lol.

Reena Arya - a couple of years ago

Very informative thanks for great read and insightful about the pros and cons of the 90 day extension

Cherie - a couple of years ago

I came to this article not because I use an affiliate link, but because an organization I want to support has an affiliate link to just buy anything through it. So I always click that bookmarked link to get to Amazon. I buy a lot of things on Amazon, but I often put things in my cart and then click “save for later.” That’s easier to me than a wish list. So I wonder if I put something in my cart, saved it for later, came back through the link once again, moved it to my cart and bought it, would they get their share? I just always wondered because I want to make sure they get it.

AED - a couple of years ago

Hi AuthorityAzon!

Great read and things are clearer to me now. But I still got this little issue. What if instead of using a form to let potential customers manually click the add to cart button (using the html you provided above)and just use the amazon add cart url then append the product url along with your associate id, will it be considered a valid addition to the cart or is it something technically not sound to do? I mean will it cause me to get my account closed? Sorry but I really need this to be answered…


ganapat - a couple of years ago

Great post..!
i Have question, Suppose a visitor first visit amazon from my affiliate link and then after they visit some other website and visit again amazon from that other website’s affiliate link and buy a product then who got the commission? me or the other website?

Sine - last year

Thank you, great post!
Question: Do you know how the affiliate link works for people who order items as a subscription?

Laura - last year

So, if I make an affiliate link on Tuesday and someone doesn’t click on it until Friday- then it’s too late and I get no credit? If that’s the case, I have to make new links every 24 hours? Sorry, that’s the part I didn’t understand.

Michael - last year

Thanks for such useful Info Dom.Very happy to subscribe HPD mail list. I Will try it on my site

Neelkanth bhatt - last year

Hi, authorityazon

Great Read. I was getting so confused about it. But your insight really helped and now will do my work accordingly.
But, I have a question. What about when someone adds a product to the wishlist? WHich cookie works at that point in time?


jimmyg - last year

you cleared up a lot of fogging sales pitches out there trying to sell one a plugin.. Thanks 😉

Musclerig - last year

My question is: What if I get the link of the add to cart page of a product and visitors get to amazon from that link. Will they get a 90 day cookie or 1 day?

Lets suppose it is everlast punching bag. I clicked ‘add to cart’. Now through site stripe, if I get the link and add it to my blog. When a visitor clicks on this link he will see a page ‘add to cart’ of everlast punching bag. So, now is the cookie a 90 day cookie?

Edwards - last year

Thank You So much, you have clarified everything.
I was initially told the “add to cart” button let’s you get commissions from a customer for every item purchased within the 90 days period.
Like you have noted, the best thing is to know how the different links work and determine/know when to use them.
Thanks AuthorityAzon!

Odira Ndubuisi - last year

This is really interesting. I was considering the pros vs the cons and I think the cons outweighs the pros in most cases.

ayaz Butt - last year

I Had read several time it’s quite hard to understand Anyways Nice posting

SEAN - last year

Well written. Thank you.

Coaching Köln - last year

Thanks for clearifying. As you said there is a lot of missleading information on the web.


Barbara Henson - last year

I am rebuilding my site TexasMissB and the url I mentioned is just a ‘test page’. I would appreciate your opinion about the few Amazon links on that page. Most do carry an Associate ID within the link. I have no intention of using WordPress so have no need of an Add to Cart function. What I would like to know, are the Amazon links done correctly on the page mentioned? After I make sure all links are A-OK, that webpage will become the site’s homepage for me to promote.

Will check here again often for a post and/or reply. In the meantime, you and yours be careful when you are out and about in the offline world.

Jesse - last year

Best article I’ve seen on this 90-day cart button.

So let me see if I understand this correctly… The 90-day add to cart is essentially in addition to anything they buy in the first 24 hours, which means that with the 90-day add to cart you still the 24 hour cookie get commissions for unrelated products they may purchase in that 24-hour window?

Only drawback I see is the blank page could turn some people off and also the blank cart page doesn’t show any related products or stimulate further shopping on Amazon…

Are my interpretations correct?


Yair - last year

My question is: How do I get stats of ‘add to cart’ clicks? Can I track it?
Many thanks.

Gadget Reviews - last year

Thanks, this article is great… Clarify my all confusion about 24 hours cookies vs 90 days extension.

Mike - last year

On other advertising platforms they provide an option for 30, 60 or 90 day cookie. Why would someone want a smaller window than 90 days for cookies?

M G M Nair - 11 months ago

Nicely explained how the 90 days Amazon cookie works.
Thanks for clarifying everything in detail.

Sandeep Chandra - 9 months ago

So that means I don’t have to generate a new link in every 24 hrs.
So How Long My Link will Stay? ? What’s the validity of a affiliate link?
Suppose I generated a link and No One visited my site.
So How Long My Link Will Be Legal?
Can You Brief me on this plz

Alex - 9 months ago

Late to the party, but still considering using add to cart links. I think the best idea is to do split tests and choose the best option for you.

Akimat - a few months ago

Thanks for this!
What if a customer clicks on the link from within a blog post.
24 hours pass and they didn’t purchase anything.
They click on the same link in the same blog post – or the same link in a social media ad – over 24 hours later and do purchase something.
Will I get paid a commission?
Is there a limit to how many times they click the original link and I get paid from their related purchases?
Or, is it a one click per link rule to be paid a commission?


tuky - a couple of months ago

The 90-day add to cart is essentially in addition to anything they buy in the first 24 hours, which means that with the 90-day add to cart you still the 24 hour cookie get commissions for unrelated products they may purchase in that 24-hour window?

Edward - a couple of months ago

Finally, a straightforward article on this 90 days cookie. Thank you!
