Yeah, this sounds like a conversion path issue rather than a views problem.
If your TikTok account can't use a clickable bio link yet, even a viral post has way too much friction. People have to remember the name, leave the app, search manually, then figure out what the offer actually is. Most won't bother.
I'd test one really specific CTA instead of pushing signups directly. Here's what's worked for me:
✨ Ask people to comment a keyword
📌 Pin that comment with the exact product name and next step
🎯 Make your profile bio say one clear outcome, not a vague description
🔁 Use the same phrase in the video, caption, and profile name if you can
🛠️ Manually DM commenters the signup link until you unlock the clickable link
Also dig into TikTok analytics for profile views. If that 60k video drove almost no profile visits, the content was interesting but didn't create intent. If profile visits were high but signups were zero, then your landing page or offer's the bottleneck.
