What is 1L? Did you mean K?
Look at your analytics.
If you still see traffic from the FYP it’s not a shadowban but your videos did not perform well.
I have videos with 150k likes but the next one will only get 10k. It is how TikTok works.
I already warched some of your videos. Overall, everything seems nice. Make sure your texts are centered. Sometimes words are hidden behind the video caption/description or the navigation on the right. Also, lower the volume of your music, and up your own voice, while speaking. You can do that using the Volume settings on the right.
I already made an alt account on the same device, and everything is alright. They obviously allow owning multiple accounts, since there’s an option for that. Avoid making more than 3 though.
I believe that’s a myth. I’ve deleted multiple videos, and that hasn’t affected or reset my algorithm. But again, avoid deleting too many. Once in a while is fine.
My opinion:
You are not consistent with your theme. You make travel videos but also reactions/duets to “funny” or “cooking” videos. I also saw a video “like if you were born before…” Stay in your own niche if you want people to remember you on a particular topic.
Videos are too slow from the beginning.
Most people decide whether they will swipe or keep watching within the first 2/3 seconds so make those the most entertaining. Transitions are also slow. You can skip those.
And as mentioned previously, the BGM is sometimes too slow we can’t hear what you’re saying.
