Viewability Metrics in Banner Ad Campaigns

Key Benefits

Accurate Performance Measurement

Understand the true reach and impact of your campaigns by focusing on viewable impressions, not just total impressions. Adjust your campaign configuration to achieve the best results.

Improved Optimization

Identify high-performing and underperforming ad placements. If an ad has high impressions but low viewability, it may be placed in a location that users rarely scroll to.

How to Use

  1. In your campaign reports for banner ads, you will now see four new tiles: “Win Percentage,” “Auctions Won,” “Viewable Impressions,” and “Viewability.”

  2. Monitor these metrics alongside your other campaign data (like clicks and CPM) to get a complete picture of performance.

  3. Use the data to find any issues with your targeting options or adjust your bidding strategy.

Reserve Prices for Banner Ad Slots

Key Benefits

Protect Inventory Value

Prevent your premium ad slots from being undersold in low-bid auctions.

Increase Ad Spend and Revenue

By setting a minimum price, you encourage autobidding campaigns to bid higher, which can lead to increased overall ad spend and revenue.

Maximize Yield

Strategically set reserve prices based on demand, seasonality, or slot performance to maximize the yield from your ad inventory.

How to Use

  1. Share with Topsort a file with slot ids and reserve prices.

  2. Enter the minimum CPM and CPC you are willing to accept for that slot.

  3. Our autobidding system will not place a bid below this price for that specific slot.
