What is Viewability Rate?
Viewability Rate measures the percentage of your ad impressions that were actually viewable — meaning at least 50% of the ad was on screen for at least 1 second (2 seconds for video). Paying for ads nobody sees is wasted budget.
Worked Example
A campaign serves 500,000 impressions, but only 350,000 meet the viewability criteria. Viewability Rate = 350,000 ÷ 500,000 = 70%. The MRC and IAB recommend targeting 70%+ viewability for quality inventory.

Engagement Rate
Engagement Rate shows what percentage of people who saw your ad interacted with it (liked, shared, commented, expanded, etc.). It's a measure of creative quality and audience relevance beyond passive viewing.
CPM
CPM (Cost Per Mille) is the price you pay for every 1,000 times your ad is shown. It's the most widely used metric for measuring the cost efficiency of an awareness campaign. Lower CPM means you're reaching more people for less money.
Frequency
Frequency measures how many times, on average, each unique person in your audience has seen your ad. Optimal frequency balances brand recall (too few = forgotten) against over-exposure and ad fatigue (too many = annoyance).
CTR
CTR (Click-Through Rate) measures how often people who see your ad actually click on it. A higher CTR indicates your creative and targeting are resonating well with your audience.
Expert Insights
How do I improve my Viewability Rate?
Improving Viewability Rate requires a dual focus on quality and efficiency. For UNIVERSAL METRICS metrics, we recommend auditing your top-performing segments and re-allocating budget from underperforming areas to those with higher baseline Viewability Rate potential.
Is Viewability Rate a primary KPI?
While Viewability Rate is a critical indicator of regional performance, it should always be viewed alongside downstream metrics like ROI to ensure volume isn't coming at the expense of profitability.
