Welcome to our Online Advertising Glossary. Use it to cut through the jargon (and keep ahead of the competition).

We’re constantly updating the glossary with basic definitions, as well as more in depth explorations of digital marketing terms. However it there is something you need to know about urgently (or if you think there is anything important missing), please get in touch to let us know at

We’re also happy to take submissions if you would like to define something yourself.

Please note: The below contains terms related to digital marketing, as well as acronyms, abbreviations, and synonyms.

If you’re looking for something specific, we recommend you use the search box. You can also use the alphabetical or category filters to narrow your results.
