The purpose of retargeting is to increase conversion rates by reminding visitors that they are interested in a particular product or service from you. If a visitor leaves the website without taking an action, such as making a purchase, retargeting can help ensure that the visitor returns and makes the purchase. Targeted advertising also allows companies to promote additional products or services that may be of interest to the visitor.Retargeting is an effective online marketing strategy that can be used by businesses of any size and in any industry. However, it requires careful planning and implementation to ensure that advertising is targeted and effective. Companies should be aware that retargeting can also be perceived as disruptive if used too frequently or inappropriately.
