Personalization vs targeting

Targeting and personalization are often used as synonyms, but they move in opposite directions. Targeting chooses which people receive a fixed message or offer. Personalization chooses what a given person sees. Targeting varies the audience; personalization varies the content.

Distinguishing test: what is fixed and what varies?

Ask which direction the variation runs. Targeting fixes the content and varies the audience: one promotion is shown to everyone who matches a rule, and the work is deciding who qualifies. Personalization fixes the person and varies the content: two people in the same campaign see different messages, and the work is deciding what each one should get. Across people for a fixed message is targeting. Across content for a fixed person is personalization.

Why they get confused

They get confused because they almost always run together. A retailer targets lapsed customers, then personalizes the offer each lapsed customer sees. A publisher targets subscribers, then ranks a different front page for each one. The campaign has a targeting step and a personalization step, and in casual use both get called “personalization.” Pulling them apart matters because they fail in different ways: a targeting problem is showing the right message to the wrong audience, while a personalization problem is showing the wrong content to a correctly chosen person.

Where each one lives

Targeting is mostly an upstream, eligibility question. It decides audiences for ads, campaigns, and offers, and it is where tools like audience builders and ad platforms do their work. It is answered before anyone sees anything.

Personalization is the downstream, experience question. Once a person is eligible, it decides what they actually see: which product, which ranking, which message, which layout. It is answered at the moment of the visit, from data about that person or context.

Why the distinction pays off

A team that says it “does personalization” may only be targeting: sending one message to a well-chosen list, with no measured change to any individual’s experience. That is a legitimate and useful thing to do, but it is not the same capability, and it is measured differently. Targeting is judged by whether the right people were reached; personalization is judged by whether varying the content for each person caused a better outcome than showing everyone the same good thing. Naming which one you are running, and which one a vendor is selling, is the first honest step.

The two also sit at different points of the personalization loop: targeting narrows the unit the decision is for, while personalization is the decision itself. For the neighboring distinctions, see personalization vs customization and recommendation vs personalization.
