When a video is auto posted, Scaled Creator watches for people who comment your chosen keyword on that post. When someone comments the keyword, your product link is automatically sent to that person by DM, so the right link reaches exactly the people asking for it.
Do I need to send anything manually?
No. You don't have to send anything manually. The automation handles delivering the product link to engaged commenters.
What if two videos use the same keyword?
Two videos can share the same keyword. Each person still only receives the links attached to the specific video they commented on.
Will I earn Amazon commission on these links?
Yes, as long as you've connected your Store ID (Amazon also calls this your Tracking ID or Associate Tag). Your links already have your Store ID embedded in them, so you earn commission from Amazon on qualifying purchases.
