CPM – Cost per Mile (CPT – cost per thousand)
Price model of Internet advertising based on impressions. CPM is the same like CPT. This model is more similar to Flat Rate then CPC/CPA.
CPM – Cost per Mile (Cost per 1000 Impressions)
CPT – Cost Per Thousand (Cost per 1000 Impressions)
CPI – Cost Per Impression (Cost per 1 Impression)
If you are advertiser: You pay for impressions, CPM is price for 1000 impressions.
If you are publisher: You earn from ad slot position impressions.
Example:
CPM = 10$ = 1000 impressions of ad costs 10$
Default CPM is overall (not for unique user) impressions without any guaranties that user saw the ad. Impression is generated always when HTML is loaded, but user go for next page without visual impact with ad (for example ad in context and under scrolling area).
User reloading factor:
Ad-servers have/not have reload filters – if user reloads the same page several times – ads on CPM model will or not use impression pool:
| Ad-network/site without “reload” filter | Ad-network/site with “reload” filter | |
| User reloads the same page 100 times |
