The following diagram and description are numbered in order to explain more easily how the first tier works when using an Inventory Source tag:
Follow the numbered items in the diagram with their corresponding explanations below:
- In essence, Inventory Sources (also known as INS), are domain lists of all your properties that include a set of criteria that define the main characteristics of the ad requests that will come from your sites. These criteria include ad request information such as:
- Device type - Desktop, OTT, Mobile (App/Web) etc.
- Publisher domains.
- Player supported formats VAST or VPAID.
Note: If an ad request is made from an unlisted domain or does not comply with your set criteria, the ad request will be filtered out and disregarded.
- After creating an Inventory Source within the Video SSP platform you will be able to generate an Inventory Source tag. This tag is a URL address that includes several query string parameters and values used to transfer information to the Video SSP platform when a player sends an ad request. The Inventory Source tag is then placed in an AOL or any 3rd party player that supports ad requesting (the arrow highlighted in blue).
- When the player on the publisher's site reaches an ad opportunity, it sends out an ad request to the Inventory Source tag (highlighted in black). This request includes important information such as the device type, opportunity type (Pre/Mid/Post-Roll) and other important information for the Inventory Source to evaluate.
- If the ad request coming from the player matches all the Inventory Source criteria, it will be then passed to the highest priority Digital Ad within any of the matching Campaigns. The Digital Ad will then send the advertisement back through the chain for loading on the requesting player.
