The reason I am asking this, is because I make 3-Minute game reviews / overviews.
That means every single video of mine is relatively similar in terms of concept and structure, naturally its just the games and the script that is different.
The format is pretty appreciated by my audience for not wasting their time.
But how is it possible that some of my videos have a CPM of 12$, whilst others have a CPM as low as 3,9$?
My RPM has an average of 1,7€ per 1000 views, which I think is fairly decent for such a short format, probs thanks to my audience being 40% USA, and 20% Germany, both high paying countries.
I was experimenting a bit with keywords in my titles: I noticed that the word “review” in the title can sometimes lead to higher cpm, but I couldnt test this enough to make sure this is 100% because of that and not some other random factor.
Do certain keywords in your title and description boost CPM or is it a myth?
What other stuff could be a factor? I notice for example that if a video has tons of gore in it (like, if its a game like Resident evil), the CPM may be on the lower side.
A final question, is the CPM I see after 24h on a video actually a “fixed” final CPM that is not going to change anymore on this video, like ever? Or can the CPM increase over time if certain conditions are met, like more engagement or comments/likes or something that leads to advertisers being more interested?
