It’s one of the most common complaints I hear from TikTok Shop affiliate creators. They make a video, it starts selling, the brand reaches out for their Spark code, the brand turns it into an ad, and then the creator notices something: the commission on ad-driven sales looks lower than what they were expecting.
Cue the accusatory messages. “You changed my commission rate.” “You’re stealing my commissions.” “Why am I making less per sale when my video is clearly working?”
I get it. On the surface, it looks suspicious. But here’s the thing: in almost every case, nobody is cheating anyone. What’s happening is written into how TikTok Shop’s commission system works, and once you understand the structure, it makes complete sense from both sides of the relationship.
Two types of commissions, two very different situations
TikTok Shop has two distinct commission rates that can apply to the same product. The first is your standard commission rate. This is the rate you agreed to when you joined a collaboration. When someone watches your video organically, clicks your link, and buys the product, your standard commission is typically 10% to 25%, depending on the product category.
The second is the Shop Ads commission rate. This is a separate, optional rate that brands can set specifically for sales that result from their ad pushing your video to someone. According to TikTok’s own documentation, if someone clicks on an ad that uses an affiliate post and buys a product, the order will get the Shop Ads commission rate rather than the standard commission rate. These are two different types of sales. One happened because your content found its audience organically. The other happened because the brand paid to put your content in front of someone who otherwise never would have seen it.
Why do brands set a lower ad commission rate?
This is the part that frustrates creators, but it makes sense when you look at the math from the brand side. When a brand turns your video into a Spark Ad, they’re paying for that reach. If they’re also paying you the full standard commission on every sale that comes from that ad spend, their margin gets squeezed from both sides at once: ad costs on one end, full commission on the other.
TikTok allows brands to set this lower Shop Ads commission rate because those commissions occur as a result of an ad, not from organic views. That said, brands aren’t required to set a lower ad commission rate. If a brand hasn’t set one and they boost your video, you’ll still receive your standard commission rate on those ad-driven sales. The lower rate is optional, not automatic.
Here’s something important that works in creators’ favor. TikTok gives creators a 30-day grace period that locks in their original commission rate. If a brand raises rates, creators get the increase immediately. But if rates drop, creators keep the original rate for 30 days after being notified. This means brands can’t pull the rug out from under you mid-campaign without warning.
One nuance worth knowing: the Shop Ads commission rate must be at least one-third of your standard commission rate. TikTok will flag it if a brand tries to set an ad commission rate below that threshold. So there’s a floor on how low brands can go.
The other piece of the commission puzzle that trips creators up is how TikTok determines who gets paid when multiple creators are promoting the same product. TikTok uses a last click attribution model. That means the commission goes to the creator whose link was clicked immediately before the purchase, not the creator whose content first introduced the buyer to the product.
This has a real implication for your strategy. If someone watches your video, gets interested, and then watches three other videos about the same product before finally clicking a link and buying, you’re not getting that commission. The last creator in that chain is. It’s not fair in the way that word usually means, but it’s the rule of the game. Practically, it means your content needs to be compelling enough to get the click, not just spark interest.
What creators should actually do with this information
First, stop assuming the worst when you notice a difference in your commission rates on ad-driven sales. Ask the brand directly what their Shop Ads commission rate is. Most brands running a legitimate program will tell you.
Second, if you don’t like the ad commission rate, negotiate. Ask the brand whether they’d be willing to set a higher ad commission in exchange for your authorization to use the video in their ads. Some will, some won’t, but it’s a completely reasonable thing to ask.
Third, remember the bigger picture. The sales you’re getting from a brand running your video as a Spark Ad are sales you would never have gotten from your organic reach alone. Even at a reduced commission rate, you’re earning on volume you didn’t create. That’s not a bad deal.
The creators who thrive in TikTok Shop affiliate marketing are the ones who understand how the system works and use that understanding to negotiate smarter.

Frequently asked questions about TikTok Shop commission rates
Why is my commission rate lower on sales driven by a brand’s Spark Ad?
TikTok Shop has two separate commission rates: your standard commission for organic sales and a Shop Ads commission rate for sales driven by paid advertising. When a brand pays to boost your video, they’re investing their own money to reach buyers who wouldn’t have found the content organically. The lower ad commission rate accounts for that brand investment. It’s written into TikTok’s commission structure and is not a sign of anything improper.
Can a brand change my commission rate without warning?
TikTok gives creators a 30-day protection window. If a brand lowers your commission rate, you continue earning at the original rate for 30 days after being notified. Rate increases take effect immediately. This protection exists to prevent brands from making sudden mid-campaign changes that disadvantage creators who are actively promoting their products.
What is the minimum Shop Ads commission rate a brand can set?
TikTok requires that the Shop Ads commission rate be at least one-third of the standard commission rate. So if your standard commission is 20%, the lowest a brand can legally set the ad commission is around 6.67%. TikTok will flag any attempt to go below this floor.
What is last click attribution, and how does it affect my commissions?
TikTok attributes the commission for a sale to the creator whose link was clicked immediately before the purchase, rather than to the creator whose content first introduced the buyer to the product. If a buyer watched your video first but clicked another creator’s link before buying, that creator earns the commission. This is why content that compels an immediate click matters as much as content that generates interest.
Should I give a brand permission to use my video as a Spark Ad?
Generally, yes, especially if your content is performing well. Spark Ads place your video in front of audiences far beyond your organic reach, which increases commission-earning opportunities even at the lower ad rate. If you’re concerned about the ad commission rate, negotiate for a higher rate before granting the Spark code rather than withholding the code entirely.
