Almost 24 hours now since uploading 2 videos, the videos are indexed and showing up in YouTube's 24 hour search. One of the videos is showing up in the 1 week recent search, the other one is not.
It seems like one of the videos was ghosted/flagged as spam, because it is not showing up anywhere outside of the 24 hour search for any of the long tail low competition keywords. I am finding lots of unrelated low quality videos, but I get to the end of the results and my video was nowhere. It could just be delayed in indexing, I am not a YouTube expert.
The other video is actually doing OK ranking #1 in the 1 week recent search for 1 of the long tail low competition keywords, but is also not appearing for some of the others at all. I think another few days will be needed for maximum results.
So, nothing conclusive right now for results!
