The world of AdTech and ad optimization contains multiple categories, subcategories, terms, formulas and more. Here in this post, we want to help save you time and avoid confusion by providing you with the ultimate list of AdTech related terms.
Below you’ll find an ever-growing list of 80+ terms and definitions. Let’s get started!
Ad unit is a term commonly used to describe the advertisement space on a website/mobile app – IE a 300×250 ad unit. It’s widely used within Google’s range of advertising products such as Google Ad Manager, AdExchange and AdSense.
This is the unique ID that identifies a specific ad unit on a website or app.
Ad price floors are the lowest price that a publisher will sell their ad inventory for on the open exchange. IE If a publisher sets their ad price floor at $1.25 it means that a publisher will not accept bids lower than $1.25 for placement on their website/mobile app. Applying price floors is an advanced tactic that publishers will use to find the optimal price that advertisers are willing to pay. They also balance their price floor strategy with the coinciding fill rate for their ad inventory. Find out how to effectively optimize AdX price floors in our guide.
Ad inventory refers to the number of ad impressions available for sale on a publisher’s website or mobile app. In other words, these are the commodities available for the advertisers to buy on the website.
An ad network is a company that brings together advertising demand and helps them reach their audience through a list of qualified publishers. Both publishers and advertisers utilize ad networks to sell and buy advertising inventory. Check out our list of the best ad networks here.
An ad request is an action where your ad server sends a request to fill an ad unit with an advertisement. An ad request is made when a user starts loading your webpage/mobile app. The ad request action will happen for every ad unit on a specific webpage. Ad requests can be counted even if no ads were returned from your advertisers.
Ad mediation typically refers to ads being served in a mobile app environment. Here the goal of ad mediation is to increase the advertising demand for your mobile app by calling multiple ad network SDKs to bid on your inventory. Ad mediation helps publishers host competitive auctions with their advertisers and typically drives up the ad earnings for the publisher. Check out our list of best app ad networks here.
Ad servers help publishers gain better control over their ad inventory by giving them access to various features such as ad management, rotating creatives, direct selling of inventory, advanced reporting, and much more.

Backfill refers to ads that you can use when for some reason ads that were reserved did not serve. This helps publishers monetize as much ad inventory as possible.
