Short version. Free for life. One link per placement. The reward lands in your wallet the moment a order is counted, and you keep all of it.
The description link, finally measured
YouTube tells you clicks on a description link in aggregate. It does not tell you the city, the platform the click actually opened on, or whether the click became an order. A Shopmycode link in the description shows all three, live, and pays the reward the moment the order is counted.
The gap between a view and a sale on YouTube is wide and slow: people watch on a television, then open the link on a phone two days later from a WhatsApp forward. The live view shows that second step as it happens — the platform the open came from, the city — and the result when the order is counted, which is why a tracked link in the description is worth more to you than the raw click count YouTube shows.
Description, pinned comment, Short, community post
Use a different link in each place. Long videos and Shorts behave differently; pinned comments outperform descriptions for some channels and underperform for others. After a few videos you know your own pattern, and you can tell a brand precisely what a placement in your description is worth.
Taking brand offers
Offers state the reward and the budget left. Take one, get a link and a ready-made blurb, and put the link where it belongs. The brand sees your link's numbers; you see the same ones. A brand that is happy can invite you to a private campaign with its own reward.
Apps and stores
For app links, one link sends iPhones and Android phones to the right store, and the sign-up inside the app is the result. For marketplace products, the store's order reporting attributes the order to your link on the marketplace's schedule; the platform tells you what is live and what is waiting.
Keeping your channel safe
Disclose referral links. Do not use clickbait the brand's page cannot honour. Do not send bought traffic; results from it are reversed and your standing with brands is what you are actually building here.
