Definition:
Remarketing is a digital marketing strategy that addresses people again after they have interacted with a brand, website, application, advertisement or communication.
The previous interaction may be used to build an advertising audience when the platform has permitted signals, or to continue a relationship through owned channels such as email when there is a valid basis. Cart abandonment is a common case, but visits to a category, video views, application use and records in a customer database can also be used.
Remarketing and retargeting are often used as synonyms. In some contexts, retargeting is reserved for behavioural advertising while remarketing also includes communications based on first-party data. Terminology varies between providers, so the specific operation of each campaign should be considered.
Why create a remarketing campaign
A remarketing campaign adapts the message to the previous contact. It can remind someone of a viewed product, present related content, help them continue a task or exclude people who have already completed the action. This segmentation can make communication more pertinent, but it does not automatically turn a person into a customer or guarantee more conversions.
Audiences can also sequence messages by stage, support comparisons between groups and control the number of impressions. Frequency matters: excessive exposure may be intrusive, while a window that is too short or an audience that is too small can limit delivery.
Results should be measured according to the objective through impressions, reach, clicks, subsequent actions and costs. The attribution of a conversion does not by itself establish that the advertisement caused it, particularly when the person already knew the brand or used several channels.
Remarketing must respect consent settings, platform policies and applicable law. Not every visit can be added to an audience, and certain categories of data, products or personal circumstances are subject to additional restrictions.
How to create a remarketing campaign
The process begins by defining the action that identifies the audience and the outcome to be achieved. Measurement is then configured through tags, events, application integrations or permitted first-party data. Collection should be tested before the campaign is activated and documented together with consent controls.
Rules may include visited pages, viewed products, time since the interaction, completed actions and exclusions. People who abandoned a purchase are often separated from those who completed it, and recent visitors can be distinguished from users with an older relationship.
Dynamic remarketing uses a catalogue to show products or services related to what the person viewed. Non-dynamic advertisements use creative assets defined for each group. Depending on the platform, campaigns may appear in search, display, social media, applications or video. Automated email is another form of continuity, but it depends on having an address and the corresponding legal basis.
Before increasing investment, audience size and duration, exclusions, frequency, alignment between the advertisement and landing page, and conversion deduplication should be reviewed. Performance should be compared with other groups and periods, not only with data attributed by the platform itself.
