Where do you find out those things?
Battlefield 1 is my favorite game at the moment what about that?
I get my info from the horse's mouth: Youtube and Google trends. When you search for anything on YouTube, it will give you the amount of results for that particular search term. Google Trends tells you how popular the search term is. 'Battlefield 1' has over 5 million search results. Your channel wouldn't rank for that right now. Now 'battlefield 1 epic moments' has 231,000 search results with decent monthly search volume and low competition. Create a series titled "Battlefield 1 Epic Moments" and when you have enough videos, put them all in a playlist and name it "Battlefield 1 Epic Moments." The more videos you create around that niche, the more the youtube algorithm will recognize your channel as an authority for it. Remember, to also rank well on youtube, your videos need to be relevant. Make sure your videos are titled with "Battlefield 1 Epic Moments" first, before you add any additional info to the title. For example: 'Battlefield 1 Epic Moments - One shot kills Part 1' or 'Battlefield 1 Epic Moments - Blowing Up Tanks with a Grenade Launcher.' Create titles that sound interesting and enticing. Make sure 'Battlefield 1 Epic Moments' is also in your description and tags.[DOUBLEPOST=1485116687,1485116292][/DOUBLEPOST]
Moved to the strategy / technique forum.
There seems to be a bit of confusion with terminology.
Organic growth of a channel means growth that happens from within. It's views that come in automatically without you haven't to run around manually promoting, posting or running advertising campaigns. When people refer to organic growth, we're talking about traffic sources such as "suggested videos" (in particular when your videos are suggested on other channels' videos), google search and YT search. ie once you start getting significant traffic from those sources, your channel will be automatically bringing in new viewers and subs every day without you having to do anything. That's why it's called "organic".
Social media and forums etc isn't organic because it's not automated. As soon as the creator stops posting to social media, forums etc, promoting, then the views will dry up. Also these sources tend to bring in views with lower than average audience retention because you are pushing your content. Organic growth has better audience retention because people are actively searching and clicking out of choice. Poor audience retention from the non-organic sources will harm your chances of getting decent traffic from the organic sources (because the organic sources are driven by the algorithm which looks at the view time)
Yeah, what Crown said.
