The Ultimate Ad Tech & Ad Revenue Metrics Glossary

Ever feel like you're drowning in ad tech acronyms? That’s fair. We've compiled this comprehensive glossary to demystify the numbers that matter, translating complex concepts into actionable insights. 

Whether you're optimizing your existing monetization strategy or building one from scratch, this resource will help you confidently speak the language of digital advertising and make data-driven decisions that boost your bottom line. Consider this your decoder ring for the secret language of ad tech.

Revenue per Thousand Impressions (RPM)

Definition: RPM measures the estimated revenue generated per 1,000 page impressions.

How It's Used: Publishers use RPM to evaluate overall monetization effectiveness across their entire site, comparing performance across different time periods, content sections, or after implementing new strategies.

Calculation: RPM = (Total Revenue ÷ Total Number of Page Impressions) × 1,000

Publisher Tip: Focus on RPM as a holistic performance indicator rather than optimizing for single ad units. Higher RPM often comes from improved content, strategic ad placements, and better user engagement metrics.

Revenue Per Session (RPS)

Definition: RPS measures the average revenue generated each time a user visits your site, regardless of how many pages they view.

How It's Used: Publishers track RPS to understand the monetary value of each visitor session and to evaluate user monetization effectiveness.

Calculation: RPS = Total Revenue ÷ Total Number of Sessions

Publisher Tip: Increasing pages per session through better internal linking and content recommendations often boosts RPS more effectively than adding additional ads to a single page.

Page Revenue Per Mille (Page RPM)

Definition: Page RPM measures the estimated revenue earned per 1,000 page views.

How It's Used: Publishers use Page RPM to evaluate the monetization effectiveness of specific pages or content types.

Calculation: Page RPM = (Total Revenue ÷ Total Page Views) × 1,000

Publisher Tip: Compare Page RPM across different content categories to identify your most valuable content types, then produce more similar content to boost overall site revenue.

Cost Per Mille (CPM)

Definition: CPM represents the cost an advertiser pays for 1,000 ad impressions.

How It's Used: Advertisers use CPM to plan and budget campaigns, while publishers use it to understand the value of their inventory to advertisers.

Calculation: CPM = (Cost of Ad Campaign ÷ Number of Impressions) × 1,000

Publisher Tip: Premium content and highly engaged audiences typically command higher CPMs. Invest in creating quality, niche content that attracts valuable audience segments.

Effective Cost Per Mille (eCPM)

Definition: eCPM is the actual revenue generated per 1,000 ad impressions, accounting for all monetization methods (including CPM, CPC, CPA).

How It's Used: Publishers use eCPM to compare performance across different ad networks, placements, and formats on a level playing field.

Calculation: eCPM = (Total Revenue ÷ Total Number of Ad Impressions) × 1,000

Publisher Tip: When evaluating new ad partners or formats, always compare them based on eCPM rather than their stated CPM rates to get a true picture of performance.

Gross Revenue

Definition: The total advertising revenue before any fees or revenue shares are deducted.

How It's Used: Publishers use gross revenue as the starting point for understanding total monetization before costs.

Calculation: Gross Revenue = Sum of All Advertising Revenue Before Fees

Publisher Tip: Always negotiate transparency into your advertising partnerships so you can clearly see gross revenue numbers, not just net payments, allowing you to accurately assess the true value of your inventory.

Net Revenue

Definition: The actual revenue a publisher receives after all platform fees, revenue shares, and costs are deducted.

How It's Used: Publishers use net revenue for actual business planning and cash flow management.

Calculation: Net Revenue = Gross Revenue - (Platform Fees + Revenue Shares + Other Costs)

Publisher Tip: When comparing monetization partners, look beyond headline revenue share percentages to understand the full fee structure and additional value-added services that might justify higher rates.

Revenue per Article

Definition: The total revenue generated by a specific piece of content over its lifetime.

How It's Used: Content publishers use this to evaluate individual content performance and inform future content investment.

Calculation: Revenue per Article = Total Revenue Generated by Article ÷ Number of Articles

Publisher Tip: Track revenue per article by content type, author, and topic to identify patterns in high-performing content, then use these insights to guide your editorial calendar.

Revenue Per Minute of Content

Definition: The average revenue generated for each minute of content consumed by users.

How It's Used: Publishers use this to evaluate content efficiency and return on content investment.

Calculation: Revenue Per Minute = Total Revenue ÷ Total Minutes of Content Consumed

Publisher Tip: This metric reveals content that provides maximum monetization efficiency. Analyze what makes your high-performing content so effective—is it topic, format, or engagement tactics? Then apply those insights across your content strategy.

Revenue Per Engaged Minute

Definition: This metric calculates how much revenue is generated for each minute users actively engage with your content.

How It's Used: Publishers use this to understand the monetary value of user attention and to compare content effectiveness beyond page views.

Calculation: Revenue Per Engaged Minute = Total Revenue ÷ Total Engaged Minutes

Publisher Tip: Content that generates high revenue per engaged minute should inform your content strategy. This metric often reveals that in-depth, quality content outperforms clickbait in monetization effectiveness.

Seasonality Index

Definition: A measure of how advertising revenue fluctuates throughout the year relative to your annual average.

How It's Used: Publishers use this to forecast revenue, plan content, and set realistic business expectations.

Calculation: Seasonality Index = (Monthly Revenue ÷ Average Monthly Revenue) × 100

Publisher Tip: Build a rolling 13-month revenue chart to identify seasonal patterns specific to your content vertical. Use this data to plan premium content during high-demand periods and explore alternative revenue streams during anticipated low periods. 

Deep Dive: You can check out Plawire’s PEI index for a good understanding of yearly seasonality, or you can dig more into common seasonality trends.

Ad Revenue Volatility

Definition: A measure of how much your ad revenue fluctuates day-to-day or week-to-week.

How It's Used: Publishers track this to understand revenue stability and forecast business performance.

Calculation: Standard deviation of daily/weekly revenue as a percentage of average revenue

Publisher Tip: High volatility makes business planning difficult. Diversify your revenue streams across multiple demand sources, ad formats, and even non-advertising income like subscriptions or affiliate marketing to create more predictable revenue patterns.

Yield Index

Definition: A proprietary metric that compares your actual revenue against potential revenue based on market benchmarks.

How It's Used: Publishers use yield index to identify monetization efficiency and opportunities for improvement.

Calculation: Yield Index = (Actual Revenue ÷ Potential Revenue Based on Benchmarks) × 100

Publisher Tip: Work with monetization partners like Playwire who can provide yield index benchmarks for your content category, helping identify specific opportunities to close the gap between actual and potential revenue.

Average Revenue Per User (ARPU)

Definition: ARPU measures the average revenue generated by each user over a specific time period.

How It's Used: Publishers use ARPU to understand the monetization value of different user segments and to inform audience development strategies.

Calculation: ARPU = Total Revenue ÷ Number of Unique Users

Publisher Tip: Segment your ARPU analysis by traffic source, device type, and user demographics to identify your most valuable audience segments and tailor content accordingly.

Lifetime Value (LTV)

Definition: LTV represents the projected revenue a single user will generate throughout their entire relationship with your site.

How It's Used: Publishers use LTV to make informed decisions about user acquisition costs and to prioritize retention strategies.

Calculation: LTV = ARPU × Average User Lifespan (in relevant time periods)

Publisher Tip: Increase LTV by building email lists, implementing personalization, and creating loyalty programs that transform casual visitors into long-term audience members.

Session Duration

Definition: Session duration measures the average length of time users spend on your site during a single visit.

How It's Used: Publishers correlate this engagement metric with ad revenue to understand the relationship between time spent and monetization potential.

Calculation: Session Duration = Total Duration of All Sessions ÷ Number of Sessions

Publisher Tip: Longer sessions generally create more ad impression opportunities. Design content journeys that encourage deeper site exploration rather than maximizing individual page ad load.

Publisher Tip: Implement content recommendation engines and strong internal linking strategies to increase pages per session, creating more ad impression opportunities per user visit.

Related: Learn how to find pageviews per session in GA4.

Bounce Rate

Definition: Bounce rate is the percentage of visitors who navigate away after viewing only one page on your site.

How It's Used: Publishers use bounce rate to gauge initial content engagement and site stickiness, with implications for ad revenue potential.

Calculation: Bounce Rate = (Single-Page Sessions ÷ Total Sessions) × 100

Publisher Tip: A high bounce rate limits ad exposure opportunities. Analyze top entry pages with high bounce rates and implement strategic internal linking, suggested content modules, or scroll-triggered content to reduce bounces.

Related: Learn how to find bounce rate in GA4.

User Return Rate

Definition: The percentage of users who return to your site within a specified time period.

How It's Used: Publishers correlate return rate with lifetime value calculations and revenue sustainability.

Calculation: User Return Rate = (Number of Returning Users ÷ Total Unique Users) × 100

Publisher Tip: Segment return rate analysis by traffic source and entry content to identify which acquisition channels and content types drive sustainable audience relationships versus one-time visits.

User Recirculation Rate

Definition: The percentage of users who navigate to another page on your site after viewing their initial landing page.

How It's Used: Publishers correlate recirculation with revenue metrics to understand its monetization impact.

Calculation: Recirculation Rate = (1 - Bounce Rate)

Publisher Tip: Implement strategic content recommendations based on the current article topic and user behavior patterns to increase recirculation and create additional ad impression opportunities.

Cost Per Click (CPC)

Definition: CPC refers to the amount an advertiser pays each time a user clicks on their advertisement.

How It's Used: Publishers monitor average CPC to understand the value of their inventory in click-based campaigns.

Calculation: CPC = Total Cost ÷ Number of Clicks

Publisher Tip: Audiences with high purchase intent typically generate higher CPCs. Create content that attracts users actively researching products or solutions to maximize this metric.

Cost Per Acquisition (CPA)

Definition: CPA represents the cost an advertiser pays for a specific user action (purchase, sign-up, etc.) resulting from an ad.

How It's Used: Performance advertisers use CPA to measure campaign effectiveness, while publishers use it to understand their value in conversion-focused campaigns.

Calculation: CPA = Total Campaign Cost ÷ Number of Acquisitions

Publisher Tip: If you work with CPA campaigns, focus on content that addresses users further down the purchase funnel to improve conversion rates and attract more performance-based advertising.

Click-Through Rate (CTR)

Definition: CTR measures the percentage of impressions that resulted in a click on an advertisement.

How It's Used: Publishers and advertisers use CTR to gauge ad relevance and engagement levels.

Calculation: CTR = (Number of Clicks ÷ Number of Impressions) × 100

Publisher Tip: While higher CTR can indicate more engaging ads, focus on balance. Excessively clickable ads might suggest clickbait tactics that could harm long-term user satisfaction.

Video Completion Rate (VCR)

Definition: VCR measures the percentage of video ads that play to completion without being skipped or abandoned.

How It's Used: Publishers use VCR to understand video ad engagement and optimize placement strategies.

Calculation: VCR = (Number of Complete Video Views ÷ Number of Video Ad Starts) × 100

Publisher Tip: Short-form videos (15-30 seconds) typically have higher completion rates. Consider ad length, placement timing, and content relevance when implementing video ad strategies.

Cost Per Completed View (CPCV)

Definition: CPCV represents the cost advertisers pay when a viewer watches a video ad to completion.

How It's Used: Video publishers use CPCV to understand the value of their inventory for completion-focused campaigns.

Calculation: CPCV = Total Campaign Cost ÷ Number of Completed Views

Publisher Tip: Higher CPCV can be achieved by creating engaging surrounding content that keeps viewers watching. Optimize video player positioning and pre-roll timing to reduce abandonment.

Engaged-View Conversion Rate (EVCR)

Definition: The percentage of users who convert after viewing (but not necessarily clicking) a video ad for a significant duration.

How It's Used: Video publishers use this to demonstrate value beyond click-based metrics, particularly for awareness campaigns.

Calculation: EVCR = (Number of View-Based Conversions ÷ Number of Qualified Ad Views) × 100

Publisher Tip: Partner with advertisers to implement view-through conversion tracking, which can demonstrate your content's value beyond direct response metrics and potentially command premium CPMs.

Viewability

Definition: Viewability measures the percentage of ad impressions that were actually viewable by users (typically defined as 50% of the ad being visible for at least 1 second).

How It's Used: Advertisers increasingly buy inventory based on viewability metrics, making it crucial for publisher revenue.

Calculation: Viewability Rate = (Number of Viewable Impressions ÷ Total Impressions) × 100

Publisher Tip: Optimize your site layout to ensure ads load in viewable areas. Consider sticky ads for sidebars or implementing lazy loading to improve viewability rates.

Deep Dive: Dig into our complete guide on viewability for more details and best practices.

Ads in View Time

Definition: The average amount of time an ad remains viewable on a user's screen.

How It's Used: Publishers analyze this metric to understand how long users are exposed to advertisements, which correlates with brand recall and effectiveness.

Calculation: Ads in View Time = Total Time Ads Were Viewable ÷ Number of Viewable Impressions

Publisher Tip: Optimize content layout to increase dwell time in sections with ads. Using sticky sidebar units or placing ads within long-form content can significantly increase view time metrics.

Active View Rate

Definition: Google's specific viewability metric, measuring impressions that were viewable according to IAB standards.

How It's Used: Publishers use Active View metrics to optimize for Google's advertising platforms and understand viewability performance.

Calculation: Active View Rate = (Number of Viewable Impressions ÷ Total Measurable Impressions) × 100

Publisher Tip: When working with Google Ad Manager, focus on improving Active View rates by adjusting ad positions and implementing lazy loading to ensure ads are served only when users are likely to see them.

Ad Density

Definition: Ad density refers to the ratio of advertising content to editorial content on a page.

How It's Used: Publishers use this metric to balance monetization with user experience, while ensuring compliance with standards like Google's Better Ads Standards.

Calculation: Ad Density = Ad Space ÷ Total Content Space (often expressed as a percentage)

Publisher Tip: Higher isn't better. Focus on finding the optimal ad density that maximizes revenue without degrading user experience, typically around 30% for most content types.

Deep Dive: Learn best practices for ad density in this in-depth article.

Queries Per Second (QPS)

Definition: QPS measures how many bid requests an SSP processes from your domain each second, with each SSP tracking and potentially limiting this rate based on perceived inventory value.

How It's Used: Publishers monitor QPS to understand their access to demand partners, while SSPs use it to manage infrastructure load and prioritize high-performing inventory.

Calculation: QPS = Total Number of Bid Requests ÷ Time Period (in seconds)

Publisher Tip: Focus on quality over quantity by analyzing bid rates by SSP and customizing your approach for each partner. High bid rates typically lead to more generous QPS limits, expanding your access to demand. Consider working with a monetization partner with established SSP relationships if you're consistently hitting QPS caps that limit your revenue potential.

Deep Dive: Learn more about QPS with this in-depth article.

Video Start Rate

Definition: The percentage of video ad impressions that actually begin playing.

How It's Used: Video publishers track this to identify potential technical or quality issues affecting video ad delivery.

Calculation: Video Start Rate = (Number of Video Starts ÷ Number of Video Ad Requests) × 100

Publisher Tip: Low video start rates often indicate technical problems or excessive pre-roll duration. Prioritize quick-starting, properly encoded creative and consider limiting pre-roll duration to 15-30 seconds to maximize completion rates.

Video Player Size Impact

Definition: The correlation between video player dimensions and key performance metrics like completion rate and CPM.

How It's Used: Video publishers analyze this to optimize player size for both user experience and revenue.

Calculation: Typically measured through A/B testing different player sizes and comparing performance metrics

Publisher Tip: While larger players generally command higher CPMs, they may negatively impact user experience. Test a range of sizes to find your optimal balance, typically around 640×360 for in-article placement on desktop and edge-to-edge on mobile.

Ad Format Performance Index

Definition: A comparison of how different ad formats perform relative to site average CPMs.

How It's Used: Publishers use this to optimize their ad format mix for maximum revenue.

Calculation: Format Performance Index = (Format CPM ÷ Average Site CPM) × 100

Publisher Tip: Rather than simply implementing the highest-performing formats everywhere, create a strategic mix that balances user experience with revenue. High-impact formats should be used sparingly to maintain their premium value and preserve user experience.

Ad Position Viewability Index

Definition: A measure of viewability rates for different ad positions on your pages.

How It's Used: Publishers use this to optimize ad placement for maximum viewability and revenue.

Calculation: Position-specific viewability compared to site average (indexed to 100)

Publisher Tip: Create a heat map of viewability by position and device type, then prioritize your highest-value demand for positions with the highest viewability scores to maximize overall yield.

Average Position Visibility Time

Definition: The average duration that specific ad positions remain viewable during user sessions.

How It's Used: Publishers use this metric to price different positions based on actual attention metrics rather than just viewability snapshots.

Calculation: Average Position Visibility Time = Total Viewable Time for Position ÷ Number of Impressions in that Position

Publisher Tip: Price your inventory based on attention metrics rather than just placement. An above-the-fold placement with short visibility time may be less valuable than a mid-article position where users linger while reading content.

Brand Safety Incident Rate

Definition: The frequency of ads appearing alongside potentially inappropriate content.

How It's Used: Publishers monitor this to ensure advertiser confidence and prevent revenue loss from blacklisting.

Calculation: Brand Safety Incident Rate = (Number of Flagged Ad Impressions ÷ Total Ad Impressions) × 100

Fill Rate

Definition: Fill rate represents the percentage of ad requests that were successfully filled with an advertisement.

How It's Used: Publishers monitor fill rate to identify potential revenue leaks and ensure maximum inventory monetization.

Calculation: Fill Rate = (Number of Ads Served ÷ Number of Ad Requests) × 100

Publisher Tip: Low fill rates often indicate technical issues or bid floor prices set too high. Regularly test your ad setup and consider implementing a header bidding solution to maximize competition for your inventory.

Bid Depth

Definition: The average number of bids received per impression in programmatic auctions.

How It's Used: Publishers use bid depth to understand auction competitiveness and demand for their inventory.

Calculation: Bid Depth = Total Number of Bids Received ÷ Number of Auctions

Publisher Tip: Higher bid depth generally leads to higher clearing prices. Work with a partner like Playwire to increase the number of demand partners competing for your inventory.

Floor Price Efficiency

Definition: A measure of how effectively your price floors are set to maximize revenue without sacrificing fill rate.

How It's Used: Publishers analyze floor price efficiency to optimize their price floor strategies across different inventory segments.

Calculation: Floor Price Efficiency = Actual Revenue ÷ Theoretical Maximum Revenue (with perfect floor prices)

Publisher Tip: Implement dynamic floor pricing that adjusts based on historical performance, time of day, device type, and geography rather than using static floors across all inventory.

Deep Dive: Read the complete guide (and get all the templates) to managing a price floor strategy.

Header Bidding Participation Rate

Definition: The percentage of eligible impressions that receive bids through header bidding auctions.

How It's Used: Publishers monitor this to ensure their header bidding implementation is functioning effectively.

Calculation: Header Bidding Participation Rate = (Number of Header Bidding Auctions with at Least One Bid ÷ Total Header Bidding Auctions) × 100

Publisher Tip: A low participation rate may indicate technical issues or bid floors set too high. Regularly review bidder timeout settings and ensure your wrapper is properly configured for maximum participation.

Header Bidding Lift

Definition: The percentage increase in revenue achieved through header bidding compared to traditional waterfall setups.

How It's Used: Publishers measure this to quantify the value of their header bidding implementation.

Calculation: Header Bidding Lift = ((Header Bidding Revenue - Waterfall Revenue) ÷ Waterfall Revenue) × 100

Publisher Tip: Regularly benchmark your header bidding performance against industry averages. If your lift is below 20-30%, consider evaluating your bidder setup, timeout settings, or exploring wrapper alternatives.

Bidder Timeout Rate

Definition: The percentage of bid requests that don't receive a response within the allocated time limit.

How It's Used: Publishers monitor this to optimize their header bidding setup and ensure maximum competition.

Calculation: Bidder Timeout Rate = (Number of Bid Requests That Timed Out ÷ Total Bid Requests) × 100

Publisher Tip: Balance timeout settings carefully—too short limits competition, too long delays page load. Most publishers find the sweet spot between 800-1200ms, but this should be tested for your specific audience and geography mix.

Ad Request Timeout Rate

Definition: The percentage of ad requests that don't receive a response within the set timeout period.

How It's Used: Publishers monitor this to balance maximizing bid participation against page performance.

Calculation: Timeout Rate = (Number of Timeouts ÷ Total Ad Requests) × 100

Publisher Tip: Regular timeout analysis by device, geography, and connection type can reveal patterns. Consider implementing dynamic timeouts that adjust based on user connection quality to maximize revenue without sacrificing experience.

Price Floor Optimization Rate

Definition: A measure of how effectively your price floors maximize revenue without sacrificing fill rate.

How It's Used: Publishers analyze this to fine-tune their price floor strategies.

Calculation: Price Floor Optimization Rate = Actual Revenue ÷ Theoretical Maximum Revenue

Definition: The percentage of your ad inventory sold through direct deals rather than programmatic channels.

How It's Used: Publishers use this to understand their revenue mix and dependency on different sales channels.

Calculation: Direct Sold Percentage = (Direct Sold Impressions ÷ Total Impressions) × 100

Publisher Tip: Direct sold inventory typically commands premium prices. Invest in developing a direct sales strategy for your most valuable inventory while using programmatic as a complementary revenue stream.

First-Look Percentage

Definition: The percentage of inventory sold through premium "first-look" or preferred access deals before entering the broader auction.

How It's Used: Publishers use this to understand their revenue composition and evaluate the effectiveness of priority access arrangements.

Calculation: First-Look Percentage = (First-Look Revenue ÷ Total Revenue) × 100

Publisher Tip: Consider offering first-look access to strategic partners at premium CPMs while carefully monitoring the opportunity cost against broader auction potential, especially during high-demand seasons.

Programmatic Direct Percentage

Definition: The percentage of programmatically transacted inventory sold through direct deals (PMP, Programmatic Guaranteed) versus open exchange.

How It's Used: Publishers track this to understand their revenue security and premium demand relationships.

Calculation: Programmatic Direct Percentage = (Programmatic Direct Revenue ÷ Total Programmatic Revenue) × 100

Publisher Tip: Develop a tiered inventory strategy, reserving your highest-performing placements and audience segments for programmatic direct deals to secure premium rates with guaranteed volumes.

Private Marketplace (PMP) Deal Performance

Definition: Revenue and fill rate metrics specific to private marketplace deals.

How It's Used: Publishers evaluate the effectiveness of PMP arrangements compared to open market alternatives.

Calculation: PMP Performance = (PMP Revenue ÷ PMP Opportunities) compared to open market baseline

Publisher Tip: Structure PMP deals with clear KPIs and regular review periods. Underperforming PMPs should either be renegotiated or returned to the open market where competition might yield better results.

Direct vs. Programmatic Revenue Ratio

Definition: The ratio of revenue generated through direct sales versus programmatic channels.

How It's Used: Publishers track this to understand sales channel effectiveness and optimize team focus.

Calculation: Direct

Ratio = Direct Sales Revenue : Programmatic Revenue

Revenue Concentration Index

Definition: A measure of how dependent your revenue is on specific advertisers, channels, or platforms.

How It's Used: Publishers analyze this to assess revenue diversity and business risk.

Calculation: Using the Herfindahl-Hirschman Index: Sum of squared percentage shares of each revenue source

Publisher Tip: Aim for revenue diversification with no single buyer, ad network, or platform accounting for more than 25-30% of your total revenue to protect against sudden policy changes or partner issues.

Ad Latency

Definition: The time it takes for an ad to load after a page or app is accessed.

How It's Used: Publishers measure ad latency to understand its impact on user experience and ad viewability.
