Tiktok is just really annoying, they rank high for a lot of keywords but the results will either just redirect you to tiktok's homepage or a bunch of "discover" pages with random videos that contain those keywords.

If you're on mobile you'll get asked to install the app, if you try to view a video on mobile you'll probably get asked to solve a captcha and again asked to install the app.

Say you search something related to repairing a bmw, you might get results that are "bmw mechanic", "bmw repair inclusive", "bmw maintenance meme" which just lead to those tiktok discover pages.
