How the top earners do it: sales count when shoppers buy through the creator's own link or use their discount code. So rather than tagging @glootgirl, they send viewers to their own link.
Where the link goes: in their bio.
How they tell viewers about it: inside the video itself, usually at the end. They say "link's in my bio" out loud and add it as a text overlay too. In stories, a link sticker does the job.
Important: a "link in bio" line in the post caption tends not to work, so it's better to say it in the video itself.
Single product in a video works best: a link that goes straight to the product shown in the video gets the most sales, so one product per video works best. The exception is Loaded Water, where the collection link works well.
Getting the links: product and collection links can be created in the Sathi dashboard. Sathi ambassador login ↗
