Editing Impression

==Topic Overview==
Impressions provide a measure of the number of potential viewers who have viewed a specific ad on a website or app. They're used in online advertising, which can be paid or free, like Google Ads, where advertisers pay for impressions. When used in conjunction with other metrics such as click-through rates (CTR), impressions can provide a useful gauge of how well an advertising campaign is performing.
===How Impressions Work===
Every time an ad is fetched from its source, and counted by the server, it's recorded as an impression. Impressions provide crucial data for calculating metrics such as CTR and cost per thousand impressions (CPM), which are vital in analyzing the effectiveness of online campaigns. Impressions are typically bought and sold on a CPM basis in the online advertising industry.
==Usage Types==
There are several ways impressions can be used and analyzed in digital marketing:
===Brand Awareness===
Impressions are a basic measure of how many people have the potential to see an ad, making them an important factor in raising brand awareness. A high number of impressions indicates a high potential audience for the ad.
===Advertising Performance Analysis===
Impressions are fundamental to several key performance indicators in online advertising. They're used in conjunction with clicks to calculate CTR, with conversions to calculate the conversion rate, and with ad expenditure to calculate CPM.
===Cost Calculation===
Many online advertising platforms charge on a CPM basis, making the number of impressions a key factor in determining the cost of an advertising campaign.
