Social Media Marketing

We're looking for freelancer to help us promote our Youtube videos. We want to increase watch time retention rate. Several freelancers provide an increase in views and subscribers, but these are bots which Youtube will not approve. They have changed their algorithm so videos are placed higher in search result by calculating the watch time for each video. Therefore we want to work with freelancers who can promote our Youtube Channel in blogs, forums, SEO (White-hat) only, and encourage higher video retention rate for time watched. Only serious freelancers are allowed to bid and we will never select those who will use bots to increase views or subscribers. Only organic and real people in our channel.
