I have my share of demonetized videos as well, lately straight after uploading even. I'm still troubleshooting it but what I do is I upload it as scheduled. Half of the time it gets demonetized in a few minutes (video not public yet) and the other half usually gets it in the first week somewhere (probably due to some worried parents flagging it as not advertiser friendly, some parents really hate our content judging from the comments...).
I have encountered that some specific sound effects trigger the AI to put it on non advertiser friendly (I had a sound effect from an insect that made it non advertiser friendly....). Funny thing I found out though is that if you upload, check if it demonetized, delete it, re-upload again (you can't re-upload it unless you delete the other copy) and repeat a few times, it passes the check and is monetizable from the start. Seems to me that the AI doesn't scan all videos when uploading but just does a certain percentage of it (maybe based on previous history/reputation?).
Anyways back to your question, the results seem to vary per month but I think it's because they started demonetizing some of my very popular videos. I've put the figures of the last few months of my second channel below as my first channel has been having a rough time and I can't get it recovered yet.

I've seen channels put lots of ads on their videos and was always worried about retention if you do so. Fact is that it doesn't seem to matter, as long as you put the ads in sections where the viewer will wait it out because it happens at an exciting point of the video. I usually put one around 1 minute and then followed by another ad every following 2 minutes. I also put an ad in the end screen section and after the video. So far have not encountered any negative side effect yet and it's much more profitable this way. Never seen any complaint in the comments either about it. As youtube doesn't put ads on each opportunity anyways, it can easily happen that you won't have an ad for ten minutes while I put like 7 or 8 markers in there...[DOUBLEPOST=1506456085,1506455600][/DOUBLEPOST]
What I did was make a new video and ad some old ones after that. I figure that the majority of the views come from people who never seen the channel before so they don't mind watching the older content after it. Judging how my own kids watch youtube, they actually like to watch videos they have watched before and keep watching it again as well. It also ads a lot of potential watch time on top of your new video. E.g. if I make a 3 minute video and I attach 7 minutes of old videos after, the people who continue watching it after 3 minutes ads a lot of watch time to the channel.
I also try something new, I believe the sweet spot is an upload every two days if you have good traction already. This way you have a lot of videos with new status on the suggested and when you have a dud video it won't hurt your channel much. Thing is that I cannot make content every two days so I reupload old videos too. I make a new thumbnail for it, name it differently and upload again. Very successful formula for me at the moment and I've seen Vlad Crazyshow have a huge success with this strategy too.
My first channel has the same videos but then without the old stuff attached to it and the success is much worse unfortunately. Same content, similar thumbnails, much less views.... Probably all related to watch time differences.[DOUBLEPOST=1506456294][/DOUBLEPOST]
Thanks
I observed "webs and tiaras/toy monster" using this strategy with much success and the same goes for Vlad Crazyshow/Niki Toys.[DOUBLEPOST=1506456437][/DOUBLEPOST]
It's all in the thumbnail/title then! I've reuploaded videos with great retention with a different thumbnail after a few weeks and had much better success with it the second/third time.
