Overview

Viewability measures whether an ad was actually seen by a user, based on how much of the ad is in view and for how long. In digital campaigns, many ads get served but are never viewed (for example, if a user scrolls quickly or the placement is off-screen).

By using viewability tools, you can focus your spend on inventory that’s more likely to be seen — improving campaign efficiency and reducing wasted impressions. Choozle even maintains a block list of inventory sources with low historical viewability to improve performance.

How Choozle Measures & Targets Viewability

• Choozle’s viewability feature is powered by Quality Alliance Viewability, which uses historical Moat data to estimate which inventory is more likely to be viewable.

• The system scores inventory based on four vectors: supply vendor, site, device, and ad format. These scores are used to filter bids - inventory that doesn’t meet a target in-view rate may be excluded.

• Because the system is based on historical data, it’s a prediction rather than a guarantee — not every impression will be guaranteed to be viewable.

Viewability Standards

Choozle uses MRC-style viewability thresholds:

• Display: At least 50% of the ad’s pixels must be in view for at least 1 second. For large formats (like 970×250), that threshold is 30% for 1 second.

• Video: At least 50% of the video player must be in view for at least 2 consecutive seconds.

How to Use Viewability in Choozle

1. When you create or edit an ad group, open Advanced Settings.

2. Choose your viewability type: display or video.

3. Set your viewability target. Options typically include 40 %+, 50 %+, 60 %+, or 70%+ in-view.

4. Note: Selecting a viewability target applies an additional CPM of about $0.18 (as of Choozle’s standard) so you’re only bidding on inventory that meets your selected in-view threshold historically.

5. If you want actual measured viewability data, you can request a viewability report via your Choozle Account Manager or Support Center.

Integration with Fraud & Brand Safety

• Choozle uses a three-tier fraud prevention system to help ensure ad quality: network blocklist, internal blocklist, and optional third-party verification via providers like Moat, IAS, or DoubleVerify.

• Viewability targeting adds a layer of protection on top of that — by focusing on inventory that historically has been viewable, you're less likely to waste spend on low-quality or fraudulent placements.

Best Practices & Optimization Tips

• Choose a realistic in-view target: While 70%+ can be compelling, higher thresholds require stronger bids. Make sure your base and max bids support your viewability goal.

• Allow some time for delivery: Since viewability targeting filters for historical performance, you may need to give your campaign time to find the right inventory.

• Use third-party verification: If you want more precise, real-time measurement, consider enabling partners like DV or IAS by submit a ticket to the Client Support Team. 

• Be cautious in app environments: Some in-app inventory may not support viewability measurement or high viewability rates. 

• Review reporting regularly: Use viewability reports to analyze which sites, devices, or formats are performing well, and refine your strategy accordingly.

Risks & Things to Watch For

• Viewability isn’t guaranteed: Historical data is predictive, not real-time, so some impressions won’t meet the target.

• Higher costs: Setting aggressive viewability targets increases CPM and may restrict scale.

• Verification fees: Third-party measurement comes with additional costs.

• Limited in-app visibility: Not all app inventory supports third-party viewability measurement; this could limit your targeting or reporting.
