Help with conversion

Hi everyone, I have a TikTok travel account to generate some extra income through affiliates. My account has 17K followers and videos with up to 500K views. I use Booking and eDreams. The problem is I’m not getting much conversion.
I use CTAs like “more info in my bio” where the link to my website is, and I also reply to direct messages, though I don’t reply to comments.
I need advice to try to fix this, anything would be a huge help.
Thanks
