Digital advertising terms and glossary

First on our list of digital advertising terms, let’s look at all the advertising terms

A

A/B test:
The method of building two different ad versions, running both of them, and then comparing the results to see which version performed better. The objective of these tests is to determine which variables positively affect user response and utilize those in our ads down the road.

Algorithm:

Alternative text:
Descriptive text added to pictures to make the page more accessible for readers and help search engine crawlers understand the context of images.

Artificial Intelligence (AI):
AI is the development of technology that can perform tasks related to human intelligence. This artificial technology can handle tasks such as visual perception, speech recognition and decision making.
