It all depends on what you consider good. I have about 64,000 views and 717 subscribers. I don't consider that good, but I don't think of it as great either. I'd say good would be one view from each of your subscribers on each video (or at least close to) so if you have 100 videos, 1,000 subscribers, and 100,000 views, that would be great. If you have 500 videos, 16,000 subscribers, and 200,000 views, you have probably done too much sub4sub. If you have 50 videos, 100 subscribers, and 100,000 views, you probably have one video that people love to watch, but the rest aren't that great or your videos just don't make people want to subscribe. That's my opinion on it, but that's all it is.
