Hello, Quick question: Does CPM means cost per thousand 'unique' visitors, or per thousand total impression?
The price of 1,000 advertisement impressions on one webpage. If a website publisher charges $5 CPM, that means the buyer should pay $5 for every 1,000 impressions of its ad.
CPM = cost per mille ( not "mile" ) or cost per thousand impressions. Whether the impressions are unique or not that's for the partners ( network / publisher ) to decide upon agreement.
CPM is based on impressions, or views of the banner.Generally the pricing is based on increments of 1000 impressions.You are guaranteed that your ad will be displayed on the web page a visitor sees.The benefits of this model are that banner will be seen a set number of times, the drawback is that you can't absolutely guarantee an exact number of hits to your web site.
Yes but there is also more stuffs to learn from many networks. Search forum, and you will find some mine and other posts about that. Many companies dont count impressions that way, they limit a lot of stuffs so the most of the time, same IP can create 1-2 or 3 impressions per hour. You send them 100k impressions but only 10k is counted, with some of them even less.
I'm not sure of that how other companies count impressions but if you see-ad many times from same ID i think this is not count for unique impression and that is mean every other impression from this ID have to be not count... I don't know but this is correct in my view...
It needs to be that way but its not for sure. I have count of impressions witch i sent to many, many companies and when i check they statistic, its funny I used mysql to record every impression so that's how i for sure know real number. Only lilit.com or something like that, if they dont have ad, or its same user, they will not serve ad again if they dont count impressions. All other companies who limit No. of impressions pir IP will show ads all the time to users but will count just some of them. Also, there are Ad Networks who count all impressions but if you send a lot of imp. they will lower your CPM. Here is some that i tested, who pay served impression, not only what they want: PremiumCPM - record and pay all impressions, they do not degrese CPM if you have huge number of impressions CPMStar - They record all impressions but CPM is different because they are combination of few stuffs Chitika - Count all impressions, dont pay anything.
Haha like the saying "There is no full happiness" ! In every area have these kind of tricks but i think there still exist cool companies who work honest
Yup, thats just some of tricks There is more posts that i wrote, its so easy to track sent imp. and see honesty of cooperation. For this entire pool of millions of networks, i found only 2 fair for now.
And the companies make money off it cause they dont track it for you, but will still get paid for it. Which is crazy.
I'd just like to point out that if you're going to be displaying ads on your website as a "publisher" you should pay attention to whether you're seeing the CPM or eCPM number. They're VERY different, and it's important to know the difference between the two, so you don't end up feeling like you're getting scammed. Also, if you're going to be working with an ad serving company, be sure to specify whether you want a CPM, CPC, or CPA campaign. They pay differently and they each have their own advantages/disadvantages.
@wrekoniz3 Yes, this is really funny thing. Looks like no one checking that. Ok, i understand if difference is ~10%, maybe ad is not loaded, or there was bad connections between servers, but after ~80%, sometimes even more difference, its not hard to add 1 line to update MySQL and see real number of served ads. Besides other good stuffs with your network, what i already mentioned many times, i like to see that i am payed for what i am serving and EVERYTHING is counted!
Yes but the chances are even if you are getting paid CPM's you will still be getting an eCPM - because if a network has enough campaigns to fill all your inventory, they will have different rates and those rates will make up the effective CPM aka eCPM. Not a lot of networks payout FLAT RATE CPM's.
True that! I just see a lot of posts here complaining about things like "I'm not getting the money they promised!" just because they're confused between the two. Thought I should mention it.
Absolutely. But part of that is the fault of the network advertising the actual rates like they do stuff like "get paid $0.25 eCPM" but the truth is - that means its not flat rate and you are not guaranteed to get that rate. Its partially false advertising which creates most of the problem. Thats why when people ask me these questions I give them a wide range, cause if they get lower than the number I mention - I lied to them. Even if I didn't mean to. You know? Not everyone does business right anymore.
