Short answer
Yes. TikTok bonus commissions still apply when you use a Soco TAP link.
How it works
TikTok bonuses (seasonal boosts, product promos, special events) are paid by TikTok.
TAP increases come from links that Soco negotiates with brands.
Because they come from different places, they do not replace each other.
What you earn
You receive:
The higher commission from the Soco TAP link, plus..
Any bonus commission TikTok is offering for that product
Both are included in your payout.
Key point
Using Soco does not remove or reduce TikTok bonus commissions.
