PPI (Pay per Impression)

PPI (Pay per Impression) is a billing model in digital marketing where advertisers pay for their ads to be displayed on a website or in an app based on the number of impressions. An impression is counted each time an ad is shown to a user, regardless of whether they interact with the ad or not. 

• Billing per View: In the PPI model, advertisers pay for each ad displayed on a website or app, even if the user does not click or engage with the ad. 
• Primarily Used for Display Ads: PPI is commonly used for banner ads or video ads, where visibility of the ad is the key factor. 
• Target Audience Reach: PPI is often combined with targeted ad placements to ensure high visibility among the desired audience. 

• Ad is Loaded: An ad is shown on a website or app of a partner. Every user who visits the page and views the ad counts as an impression. 
• Billing Happens per 1000 Impressions (CPM): Billing is often not done for each individual impression but rather for every 1000 impressions (Cost per Mille, CPM), meaning the advertiser pays a fixed amount for every 1000 views. 
• Objective is Brand Awareness: The primary goal of PPI campaigns is usually not immediate clicks but to increase brand awareness and visibility. Companies want their brand and products to be seen by as many users as possible. 

• Lower Cost per Interaction: PPI is often more cost-effective than models like Pay per Click (PPC), as no direct user interaction is required, only the visibility of the ad is counted. 
• Increased Brand Awareness: Through a high number of impressions, brands can boost their awareness, even if users don’t click on the ad. 
• Wide Reach: PPI allows advertisers to reach a large number of users since it’s not dependent on interactions. This is especially useful for brands targeting a broad audience. 
• Lower Risk of Fraud: Compared to other models where clicks or conversions are measured, PPI carries a lower risk of click fraud, as the billing is based on visibility. 

• Display Ads on Websites: Banner ads displayed across different websites are a classic example of PPI. Advertisers pay for the impressions their ads generate, regardless of whether users click on the ad. 
• Video Ads: PPI can also be used for video ads, such as those on YouTube or other streaming platforms. Advertisers pay for each ad shown to users before the video starts playing. 
• Social Media Advertising: On platforms like Facebook, Instagram, or Twitter, advertisers can also run PPI ads, where impressions are counted without requiring users to engage with the ad. 

• No Guarantee of Interactions: PPI does not guarantee that users will interact with the ad or complete a conversion (e.g., making a purchase), which means the Return on Investment (ROI) can be harder to measure. 
• Potential Wastage of Ad Budget: If the ads are poorly placed or the target audience is not accurately addressed, ad budgets can quickly be depleted without achieving significant interaction or conversion. 
• Ad Overload: If an ad is shown too frequently, users may ignore it or find it annoying, which can lead to a negative perception of the brand. 

• Targeted Ad Placement: Advertisers should ensure that their ads appear on websites or apps that are highly relevant to their target audience, to maximize visibility and brand awareness. 
• Creative and Engaging Ads: To capture user attention, ads should be creatively designed and visually appealing, generating interest even without interaction. 
• Regular Performance Monitoring: Even though the focus is on visibility, the results of PPI campaigns should be regularly checked to ensure that the ads are meeting the desired goals of brand awareness and reach. 

PPI (Pay per Impression) is an effective model for advertisers who aim to boost brand awareness and reach without relying directly on clicks or conversions. It is particularly suited for display ads and video ads where visibility is the key goal. However, companies must ensure the right ad placements and creative quality to use their advertising budget efficiently and reach the desired audience effectively.
