Keyword Logic

Overview

❗️

Warning

Keyword logical operators only apply to flight-level keywords, at ad-level the default logic uses an OR operator between keywords.

When you write keyword targeting rules in the Kevel UI, or via the API, there is specific business logic you must follow, which is described below.

If you use the Kevel API, you will want to include the string under the 'keyword' field when using the Create Flights endpoint, or the ActiveKeywords field using the Create Ads endpoint.

If you use the Kevel UI, you will add strings to the Keyword Targeting section.

📘

Note

Operators only work at flight-level keyword targeting (not ad-level).

Operators

For keyword targeting, Kevel uses 'AND', 'OR', and 'NOT' operators. Formatting for UI and API varies slightly, so please refer to the table below for the differences. between these operators

Examples

The section below provides several examples of keyword logic and targeting using different keywords.

Example 1

In this example, let's use the keywords dodge' and truck` in different requests to show how targeting will work, depending on the syntax of the request.

If you use the keyword dodge in your request, then Kevel will perform targeting of all ads including the term `dodge.'

If you place an exclamation point ! before the keyword dodge in your request, then Kevel will target anything that does not include the keyword dodge.

If, however, you use dodge and truck keywords in your request separated by a comma, then both dodge AND truck will be targeted. Note that you must include both keywords in your request.

If you would like to target dodge OR truck in your request, add both keywords in the request if using the Kevel UI. If you would prefer to use the Kevel API, use `dodge\ntruck.'

Finally, if you would like to target dodge, but not truck,, use a comma to separate the two terms and an exclamation point before `truck'.

❗️

Warning

In the examples above, this will be considered as ((dodge) AND NOT (truck)). However, a ! at the start of the line will apply to the whole line.

In other words, !a, b, c will be considered as (NOT (a) AND NOT (b) AND NOT (c)).

However, a, !b, c will be considered as ((a) AND NOT (b) AND (c)).

If you would like to target dodge and truck , or dodge and ram, review the table below for the proper syntax.

📘

Note

Using negated keywords in an OR list will negate any queries with that keyword. For example:

• fox, bunny
• buffalo, cheetah
• !sloth

Would be parsed as:

((fox AND bunny) OR (buffalo AND cheetah)) AND (NOT sloth)

This means that an ad will be served whenever fox and bunny are used together in the request, or when buffalo and cheetah are used together, but not when sloth is also passed in.
