It's been a month since I joined youtube and I've done most experiments in getting views and subscribers. One of the things I did is get some from family and friends which gave me a decent subscriber number, a decent view and also a high audience retention rate. But they are not good in repeated views so I tried the sub 4 sub thing. I made lots of subscribers, views also gets up watch time also increases likes comments and certain things went up, they are also repeat viewers in any other video but then they ruined my high retention rate.. But all in all the money average in social blade increases to $44 a year from $12 a year.. So I guess it's still worth it.. how about you guys what are your experiences in sub4sub thing?
