Well, I've managed to break my previous Reddit "record" (100 YouTube subscribers in ~24 hours) by attracting ~150 subs over a 24-hour period with my video about derivatives.
The main difference between this situation and the other one is this: for my previous record, I've done very well on just ONE huge subreddit (/r/videos, with 11 million members, genuinely huge) whereas the derivatives video did well on several smaller subreddits.
It definitely adds up, especially since you can get good placement on the smaller subreddits. I end up on position #1 of page #1 on smaller subreddits relatively frequently, whereas my best performance on /r/videos has been the last position (#25) of page one. Now, of course, I could receive insane amounts of traffic by hitting position #1 of page #1 on /r/videos (easily hundreds of subs, possibly 500+) but that's easier said than done and therefore, if I were to aim for consistency, targeting smaller subreddits kind of makes more sense.
The channel now has close to 800 subs, so "the big 1k" is close.
That's it for now, will post in this thread again when I have something new/meaningful to report.
How do you submit the videos to reddit? Lots of different submissions under one account or a fresh account for each sub you are submitting to?
