Contextual Targeting

Contextual targeting is a serving logic where adverts are placed based on the content of a page or environment instead of personal profiles. An article on outdoor sports then attracts adverts for hiking gear or travel insurance. In an era of strict privacy rules and collapsing third party cookies, the approach is enjoying a comeback.

How it works

Algorithms analyse text, images, video transcripts and metadata of a page and assign them to topic categories. Ad slots are then filled with matching campaigns. Modern systems use natural language processing to capture meaning instead of mere keywords and can even judge sentiment or brand safety. Brand safety filters keep adverts from appearing next to critical content.

What its strengths are

Contextual targeting works without personal data and is therefore privacy friendly. It hits the moment of attention because the reader is already inside the topic environment. It also works in jurisdictions or browsers without cookies and on new devices. Compared with pure behavioural targeting the profiling is broader, but the per individual precision is lower.

Practice note

Advertisers should at least establish contextual targeting as a second pillar alongside classic profiling because cookie availability in browsers such as Safari or Firefox is already heavily restricted. In email it corresponds to a good topical match of the AdSpace, that is the selection of recipient lists fitting the advertised product, which lowers waste and lifts acceptance with the recipient.
