Sorry for this question.

CPM Calculation.. are they base on total number of page views? or unique visitors/day?

How is it calculated.. and where can the public receive such information on how many unique visitors or page views are generated by a particular website?

Thanks!

Most sites sell CPM based on page views. Some of the upper end systems like DoubleClick may have ways to make it for only uniques but I don't deal with CPM on that level so I am not sure.

Than how are page views defined?

Lets say a site like craigslist.

Each time someone click on a separte ad.. is that a sepearte pageview?

Thanks

wantfieldh,

cpm is cost per thousand impressions served.

impressions and page views are the same thing.

cpm advertising requires that an advertiser pay for their ad being served. for example a $10 cpm is equal to a charge of $10 for every thousand times an ad is served.

usually cpms are sold in 50,000 - 1MM impression increments. a $10 cpm for 100,000 impression would cost $1,000.

cpms have nothing to do with clicks. in fact, there is no quarantees that your ad will even be seen, let alone clicked, but you will still be paying. the only thing that is guaranteed is that a page view or impression will occur that displays your ad.

thanks for the input mr. Chicago.

So therefore the view doesn't have to be unique? that is it can be from the same IP address.

If so, can I setup a macro to have someone keep on hitting reload? How about that cost per click one (I forgot what its called : ) CP..C?) How do we know its not the same person clicking a million times?

Thanks!

Sure people that set up macros or click parties may make a little money short term but --

1. it is hard to get money unless you are established because people will not trust you to spend ad bucks on.
2. when ppl buy clicks or impressions they will normally put a cap on what they are willing to pay
3. if you do any of the bs mentioned then the advertisers ROI is going to stink and they will never do business with you again // possibly telling people in the industry they know not to do business with you.

honesty actually is the best policy .

Yes, you can... but you wouldn't be the first person to have thought of this since 1995 >;->

Advertising networks have long had systems in place to detect fraud.

Thanks for the input guys.

Don't get me wrong, I never intend to set up macro or anything. I knew there must be some type of defensive mechnism for it, but don't exactly know what it is.

Therefore, in reality, no one is going to go out and trace everything that you do, however it will be pretty obvious if you do something fishy..

Thanks!
