CPM
CPM (Cost Per Impression, Cost per Mile or Cost Per 1000) represents an online advertising pricing model used in marketing as a benchmark to determine the relative cost of an online advertising campaign given geograohical location. By means of CPM an estimate is calculated as the cost per 1000 views of an advertisement. The CPM is not an absolute cost, only an estimate.
Short overview
The CPM (also sometimes referred to as CPI) advertising campaign model is a technique applied in the case of website banners, text links, e-mails spam and opt-in e-mail advertising. However, the opt-in e-mail advertising is being charged as Cost Per Action (CPA but it is used in the CPM advertising pricing model. The CPM model along with other fixed rate advertising deals are preferred by webmasters since the payment is done each time the advertisement is viewed so that the probability of getting paid is higher as compared to other advertising models. The CPM model refers to advertising payed based on impressions. The total price paid in a CPM deal is calculated by multiplying the CPM rate by the number of CPM units. The CPM model is in contrast with the Pay per Action model (CPA) while the cost-per-click (CPC) model is somehow between these types of advertising payment models.[1] In order to measure the effectiveness of the inventory involved in such an advertising model whether it is CPC, CPA, CPM or CPT - a related term is used: eCPM (effective cost per mile).
How does it work?
The CPM model is commonly used in the case of advertising based on cost per thousand, which refers to the cost per thousand page impressions. The websites which use CPM in order to make profit there is also used the abbreviation RPM (revenue per 1000 impressions). In this case, while CPM is typically measured by advertisers, RPM is monitored by publishers.[2] The CPM model works exactly as the CPT model being based on a flat rate (which is an important advantage for advertisers). The CPM (Cost per mile) is sometimes referred to as CPT (Cost per Thousand) but also as CPI (Cost per Impression). Depending on who earns from such online advertising models the following situations may occur:
- 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. [3]
Nowadays, there are plenty of CPM affiliate programs available to join and various effective method to earn money by means of such onlien advertising programs. These programs pay the advertiser for every 'view' that an advertisement on his website receives. The rates pay per impression programs are generally on a CPM (Cost Per Thousand Impressions) basis.
Using CPM
Advertisers are attracted by CPM advertising campaigns due to the enormous amount of visibility these models can bring. The advertisement is often viewed even when the advertisement itself is not clicked. It is believed that the advertisement is still read and that this exposure is important over the long run. If the advertisement is attractive and attracts the visitors' attention, the Click Through Rate (CTR) will be higher, thus increasing the effectiveness and the outcome. [4]
