Hi, I have some questions before try:
1. my videos on YT are made in Croatian, Polish and Bulgarian language. Will your app provide SEO effect only in english or in mentioned above languages too?
2. how many videos can I promote in the same time with one code/tier 1? can I change videos in the pool anytime (keeping the videos amount limitations)?
3. do videos must be from owned channel or can I paste any yt video link (ie my customers videos)?
