You can place pop-up ads on remnant inventory. Remnant inventory refers to unsold advertising space that publishers often fill at discounted rates. This space is ideal for cost-effective pop-up ad placements, especially for advertisers with limited budgets or seeking broader reach. Pop-up ads can effectively capture user attention, particularly when used strategically with engaging content and proper frequency capping. However, advertisers must ensure the pop-ups comply with user experience standards and avoid being intrusive. Many ad networks, including programmatic platforms, allow targeting of remnant inventory. Leveraging these channels enables advertisers to access premium websites at lower costs. Ultimately, placing pop-up ads on remnant inventory can be a smart tactic if executed thoughtfully and ethically. What do you make of this?
