Know your VAST from your VPAID? It's time to bust some jargon.

"Hey, can you send me the CPI and MAU following that campaign we ran via MRAID?"

"Uhhh...sure!"

An hour or two later, you're probably inching closer and closer to this guy...

We've all experienced the meeting where the acronym bingo cards come out,

and half the room are alienated by hundreds of terms of varying obscurity.

That's why we've compiled the A-Z of AdTech to help you learn your IAA's and PII's

If there's something missing from the dictionary,

just drop us a note in the comments, and we'll be sure to add it in!

A

Acquisition: When a visitor completes the desired behaviour, due to seeing your advert or website content.
 

Ad Agency: The ad agency typically provides an end to end service in terms of managing advertising spend - from planning, to tracking and post-campaign reporting.
 

Ad Call: When an ad position is available on a site, the user's browser asks exchanges or ad servers for an ad to show.
 

Ad Fraud: This occurs where advertisers are charged for ad placements that have never been seen by human eyes. This could be ads placed on top of the other, ads loading out of sight, paying for bot clicks, and much, much more.
 

Ad Pod: A group of video ads that fit into the same placement slot and play consecutively.
 

Ad Server: The technology used to serve, improve and monitor ads across a range of publishers. Typically this removes the need for multiple points of contact across multiple groups, and instead allows ads to be served quickly and effectively.
 

Ad Space: The space where the advert will show on a given website.
 

Ad Tag: A snippet of HTML that will contact an ad server and ask for an ad.
 

Above The Fold: The advert is visible without having to scroll down the page.

Below-The-Fold: The advert is only visible once you scroll down the page.

Bid: The price that an advertiser is willing to pay in order to serve an impression.
 

Bid Request: When a page is loaded and an ad server calls for a given impression, it submits a bid request to all eligible bidders. Bidders then decide the value of the impression and submit bids in realtime (see also, Real-Time Bidding).
