YouTube or Tiktok for marketing?

Depends. TikTok is easier to get traffic but it's very hard to find customer. Youtube if you will do it correctly will give you more customers but it's very hard to get traffic :)

For b2b its YouTube and for b2c both

Both :D

In India, TikTok is not available as an option, yet businesses and even individuals are experiencing excellent success through YouTube platform.

YouTube

Why don't we use both platforms? :) I don't think they contradict each other.

It really depends on your goals and audience. For example for my company (we developing a JavaScript library for web reporting), YouTube is the best platform for sharing tutorials, tips, and tricks.

I think both, but Youtube more convenience

I do the both, but for SaaS product, definitely I will upvote the YouTube, long tail and good for your SEO

TikTok is banned in India, so YouTube is the winner. 😃 However, even if TikTok were not banned, I would still vote for YouTube.
