I tried changing it last week and our views dropped even more after that.It won't make any difference. Tags have fairly low relevance these days (this is the consensus from the "experts"). They are generally now used for search mostly, and more so for long and mid tails you want to place in search for. But, kids 2-5 don't search. There are way more advanced signals used now to allocate suggested slots than tags - tags worked a few years ago but no longer, for the most part, unless of course for mid-long tails. You can of course try and see what happens!!
We had several growth spurts. The first came when we used the "Thomas and Friends Accidents Will Happen" trend and keywords. There were a few big channel making those videos, and we did the same, about 5 or so. Those got the first spurt of views, and took subs from about 2k to 10k. I remember we got a suggested placement on RyanToysReview, it was about 1 day's worth, but gave the initial traffic peak. Prior to that, the channel was pretty much dead for the first 3 months. After that placement, we started getting major suggested placements on many other channel doing Thomas & Friends kids at the park, sets, and accident videos. Then Thomas started to dry up (for us). We tried Disney Cars but nothing hit.I tried changing it last week and our views dropped even more after that.
If you don’t mind me asking. How did you guys grew your channel that big? What did you do when you were starting?
Now that is really the tough part. Need to get your video suggested by a channel woth more traffic to get you noticed by YTChanging tags would not change anything at all.It is all depends on how algorithm evaluate your video based on title ,audio and video captures .
