CPM is actually a stat meant for advertisement. CPM stands for “cost per mille” (mille means “thousand”). "CPM is the amount an advertiser pays to have its ads served against videos 1,000 times. Each time an ad on a video runs completely, it's called an impression"
CPM varies depending on how much an advertiser pays to display the ad. Ad price on YouTube depends on a range of factors, including bidding price, type of ad, and consistency.
So, for instance, let's assume an advertiser is paying $9 for an ad, and the ad was seen 5,000 times on your video. To calculate CPM, you'd divide 9 by 5,000 = $0.0018, then multiply $0.0018 by 1,000.
The CPA, then, is $1.80. You'll receive 55% of that $1.80 — since YouTube takes a percentage of the CPA, as well (45%, to be exact). So if you make $1.80 CPA off an ad, you'll only keep $0.99.
Additionally, there's another type of CPM: playback-based CPM. Rather than calculating the cost the advertiser pays for 1,000 impressions, playback-based CPM calculates the cost an advertiser pays for 1,000 video playbacks where an ad is displayed.
Why does YouTube CPM fall with huge numbers of views?
• Time of year: Advertisers tend to bid higher or lower depending on the time of year. For instance, many advertisers bid higher just before holidays.
• Changes in viewer geography: Advertisers can control which geographies they’d like to reach with their ads. Different locations will have different levels of competition in the ad market, so CPMs will vary by geography. If there’s a shift in where most of your views are coming from, you may see a shift in CPM. For instance, if you previously had views from a geography with higher CPMs, but are now getting more views from geographies with lower CPMs, you may see a decrease in your CPM.
• Shifts in distribution of available ad formats: Different ad types tend to have different CPMs. If, for instance, there are more available non-skippable ads in the ad inventory, CPM might be higher.
Different country also paying different rate base on the niche...In India for example,CPM rates
depend on a lot of factors like the niche of the video, audience type, audience age, click through rates and myriad other factors which comes into play.
So how to target the countries?
There is no best way but some ways may increase your chances...
1. Your selected language when uploading the video. English-American for example if you are targeting USA.
2. Your video performance in certain country,say,if your video get higher click through rate(CTR) and engagement(like,comment,share) ,longer view average....then the chances for the video to get suggested to other audience in that country is higher.
3. Language detected by YT in the video's TITLE ,DESCRIPTION AND FIRST MINUTE OF THE VIDEO.
4. SUBTITLE or CLOSE CAPTION (CC) language also will add weight
to region that corresponding to the language.
5. Videos that covering topics that trending in the search of certain countries.
And to back all the above,equip your videos with good SEO practice to emerge higher on search. And keep on uploading quality contents consistently until one get discovered or gain engagement(viral as the trending term call it).
Its a number game,the more you do,the higher chance you get.
Enjoy the journey!
