What is Ad inventory?

In an ecommerce context, Ad inventory refers to the quantity of available ad spaces that an ecommerce website has to sell to advertisers. It is pertinent for digital marketing and encompasses various placements including banners, sidebars, in-content, and pop-ups. In the online world, Ad Inventory is akin to the number of billboards a traditional advertising agency has in its possession.

Formula

In simplest terms, the formula for Ad Inventory is:

Ad Inventory = Total Ad Space – Already Sold Space

Example

Let’s consider an ecommerce website with 10 ad slots on each page and the site has 100 pages. If 400 ad slots are already sold, the ad inventory is (10*100) – 400 = 600 ad slots left.

Why is Ad inventory important?

  • Ad Inventory is crucial for both publishers and advertisers. For ecommerce companies (publishers), it represents a significant revenue stream. More inventory leads to incremented ad revenues thanks to the greater availability of ad placements. It also helps in strategizing and planning.
  • Advertisers, on the other hand, look at ad inventory as opportunities to display their ads and reach potential customers. Greater availability means better positioning and wider audience reach.

Which factors impact Ad inventory?

Improving Ad Inventory has a direct impact on an ecommerce site’s revenues. Here is how to improve it:

  • Create additional ad slots: More slots increase inventory.
  • Improve site design & layout: Optimized design can accommodate more ads without ruining user experience.
  • Increase page views: More traffic boosts the inventory as ad slots are recreated with every page load.

How can Ad inventory be improved?

Ad Inventory is influenced by many factors:

  • Site traffic: Increased traffic amounts to larger ad inventory.
  • Page views: More views result in more ad spaces being available.
  • Ad placement: Certain areas on a webpage can cater to ad placements more than others.

What is Ad inventory’s relationship with other metrics?

  • Ad Inventory often correlates with other important ecommerce metrics such as CPM (Cost Per Thousand Impressions), Fill Rate, and Page Views Per Session.
  • For instance, a higher ad inventory may lead to a lower CPM as advertisers have more choices, which may decrease the average price. Alternatively, the Fill Rate, the percentage of ads filled from the total inventory, changes as per the availability of ads.
