Ad inventory refers to the number of ad spaces a publisher has available for advertisers. Publishers follow several tactics to make their ad spaces more viewable, ultimately generating more revenue. In this guide, we will explore these key strategies and how ad exchanges come into play to optimize revenue.
What is Ad Inventory?
Ad inventory encompasses all the available advertising spaces on a publisher’s website, mobile app, or platform that can be sold to advertisers. Publishers need to consider several factors:
- Ad formats: This includes display ads, native ads, and video ads.
- Ad unit types: Popular options are in-stream video ads, out-stream video ads, classic banners, and in-feed native ads.
Example: “Publishers must choose the right ad space formats, sizes, and positions to maximize viewability and ad revenue.”
How Ad Exchanges Boost Ad Revenue
Ad exchanges are digital marketplaces where publishers and advertisers buy and sell ad inventory in real-time. These platforms use programmatic technology to facilitate efficient ad placement, optimizing revenue for publishers and cost-effectiveness for advertisers.
Common ad exchanges include:
- Google Ad Exchange
- Rubicon Project
- OpenX
Best Practices for Managing Ad Inventory
- Use Multiple Ad Formats:
Experimenting with various ad formats, such as native ads, video ads, and banners, can help publishers discover what works best for their audience. As mentioned in the transcript, a combination of ad formats can generate higher revenue. - Ad Positioning Matters:
Ads placed above the fold are typically more viewable, leading to better CPM (cost per thousand impressions) rates. Sticky ads and docked ads are great tools for ensuring your ads stay visible as users scroll through a webpage. - Monitor Viewability Rates:
High viewability rates lead to better ad revenue. Using tactics like sticky or docked ads ensures higher visibility. As the transcript shows, ads that “stick” to a user’s screen as they scroll drive higher engagement.
How to Calculate Ad Inventory
Publishers can calculate ad inventory by assessing their website’s layout and determining how many ad slots they can place on a given page without compromising the user experience. Tools like ad servers and supply-side platforms help publishers manage this process.
- Ad Refresh Tactics: Automatically refreshing ad spaces based on user events or time triggers can increase the number of impressions served. However, not all platforms, like Google Display Network, support this tactic.
Advanced Techniques: Ad Auctions and Real-Time Bidding
Using ad exchanges and ad auctions allows publishers to maximize revenue by allowing advertisers to bid on ad spaces in real-time. Real-time bidding (RTB) ensures that publishers get the highest possible price for their ad spaces. Including videos about RTB on your page can help explain this concept to your audience.
