What is CPM?

CPM is a term used to describe Cost per Mile. The word mille refers to 1,000 impressions. The most well-known advertising metric is to determine what it takes to make 1,000 impressions on websites or in an application. Paying advertisers are determined by the number of impressions they serve and ensure that their ads are seen by their intended viewers.

Pros of CPM:

  • Predictable and stable cost model:  The simple nature of charging for advert views is that, unlike models based on performance you know precisely what you’re paying for.
  • Prime for brand awareness campaigns: CPM is a reliable indicator for non-targeted ad strategies that aim to create brand awareness by tracking the number of times an ad is shown.
  • Bulk buying power:  Marketers who purchase ad spaces in bulk typically receive discounts, and leverage the bulk purchasing power with the CPM method.

Cons of CPM:

  • No guarantee of engagement: While CPM can be a cost-effective choice in large branding campaigns it isn’t a ensure the message is connecting with the viewers.
  • High investment, low interaction: The cost of CPM advertising can be a significant amount quickly If it’s not seeing substantial click-throughs or conversions from your impressions.
  • Not performance-oriented: CPM does not account for actual sales or leads, which is the downfall for performance-driven marketers.

What is eCPM?

There is a crucial metric for online marketing termed ECPM or effective cost per mile, which digital marketing professionals use to measure the money made per 1,000 impressions after adjusting for changing distributor costs and ad formats. This is the essential figure when we would like to know if ad revenue is different between the different advertising channels.

The advantages of together eCPM

  • A holistic view of campaign effectiveness: In addition to impressions, ECPM considers other metrics like conversions and clicks, giving an overall picture of the performance.
  • Universal comparison tool: eCPM compares different advertising networks, campaigns, and models on a level playing field, taking into consideration many sources of revenue.
  • Revenue optimization: Through eCPM, it is possible to maximize the budget for advertising by studying the relationship between revenue and cost.

The cons of together eCPM

  • Context is crucial: The effectiveness of eCPM depends on the context. If you don’t understand the variables that affect the calculations it may not focus on providing an accurate picture.
  • Can be more complex to interpret than CPM: As eCPM includes extra layers of data, it might be more difficult to comprehend than simple CPM calculations.
  • Not always aligned with campaign objectives: If your campaign goals don’t match with the actions that are measured in eCPM then the metric could not be as reliable.

eCPM vs CPM: A Conversion Perspective

Understand well the relations between the two parameters, in particular, the cost per mille (eCPM) and the conversion rate (CPM). Conversion rates still considered as one of the main factors, although not directly indicated in the CPM metric. A high CPM does not always mean that the conversion rate is also high, which is when eCPM comes to play a proper role in a complete description of conversion goals. A high CPM does not necessarily mean that a better performance of a campaign is achieved as it isn’t necessarily linked to conversion.

An illustration can be provided by determining eCPM if the CPM = CPM ad has a 2% click-through rate (CTR) too. Nevertheless, if a $10, CPM ad only had a 1% CTR and a $1 conversion rate, its eCPM would be lower at 0.10..20 if every 5th click led to a conversion. On the other hand, in a $10-CMP ad, if the CTR is 1% which is a low CTR and high conversion. The eCPM = $0.10 would occur..10. As in the case of this demonstration, eCPM is quantifiably superior in implementing income per impression compared to the use of CPM alone.

Why is eCPM Useful for Publishers?

The ECPM is the best metric for publishers because it directly correlates to publishers’ earnings from displaying ads on their websites. Moreover, it can be pointed out that by presenting the most effective content strategies that lead to higher earnings, eCPM is an exclusive part of web content strategy formulation and content placement decisions.
