You don't need to post 20 times a day. You need a steady rhythm across all three platforms. Here's exactly how much and how often.
Native to each platform. Not 10, not 20. A steady 3 to 5 is the sweet spot.
Between posts. Dumping them all at once smothers your own reach.
Deleting looks like bot behavior, and dead videos sometimes wake up later.
Tags and descriptions don't matter much. Five loose hashtags, some niche, some broad, whatever your competitor is doing. There's no magic formula and it won't make or break the video.
Your first 5 to 10 videos before dropping a product should be fresh concepts you recreated from competitors. After that, a chunk of your posts will be split tests, which is the next lesson.
3 to 5 a day, spaced out, native, never deleted.
Next lesson: split testing, how to keep a winner going without inventing new concepts.
