This handy list will help you decipher the acronyms when choosing metrics for your report:

​

Spend: The total amount of money paid for your ads. This is what you will be billed (taxes not included, if applicable to your state).

Impressions: an impression is equal to your ad being shown once. 1,000 impressions = 1,000 ads.

CPM (Cost per 1,000 impressions): The effective cost you pay for 1,000 impressions delivered.

VCR (Video completion rate): The % of videos watched all the way through
Actions 


Actions: The number of times that someone exposed to your ad has completed an action on your site, tracked by the Roku Pixel. These are attributed actions.

CPA (Cost per action): The amount you pay per your campaign's goal action, calculated by dividing spend into those actions. CPA does not include non-goal actions. A campaign with Page View goal that also has Sign-up and Purchase events would calculate the CPA like this: CPA = Spend / Page Views.

CPCV (Cost per completed view). The amount you pay every time your ad is viewed to completion, calculated by dividing spend by video completions.

ROAS (Return on Ad Spend). A ratio comparing how much you spent on ads and how much purchase value they drove, calculated by dividing total purchase value by total ad spend. This will only be reportable when a purchase pixel is applied with transaction values passed.

CPUR (Cost per unique reach)
: The amount you pay to reach a unique household, calculated by dividing spend by unique households reached.

Household Reach: the total amount of unique households who saw your ad

Household Frequency: the average number of times a unique household has seen your ad. A household frequency of 3 means that on average, your ad was viewed 3 times within the same household.
