How it works

Retargeting

Retargeting is an eCommerce marketing automation and personalization platform. This add-on tracks every action that your visitors are doing on your website in order to provide personalized messages aimed towards closing more orders, faster. This add-on provides user level analytics and enables key decision makers to improve each aspect of the buying funnel and discover pain points. You can uncover which of your site categories is more popular, which are your most loyal customers, and how long is your buying cycle. Retargeting includes 4 different types of messages that are automatically sent based on a set of predetermined rules. Message types already included in Retargeting: On-site messages are displayed while visitors are still browsing, and can be used to offer discounts for email newsletter subscription, present special offers for products a visitor has shown interest in, or target visitors navigating away from the page. Email messages are sent to visitors after they have navigated away from the site, based on visitor behavior, or linked to particular events such as visitors’ birthdays or Black Friday sales. SMS messages are purposely send to act as an reminder to the rest of the messages. Using SMS you can assure yourself that you are reaching all of your customers, even those who aren't constantly checking their email. Push notifications are a series of messages (automate & manual) that are sent to your visitors in order to increase sales, to reduce user inactivity or to recommend similar products. Each type of message can be customized 100% by you, to better suit every need that you might have. The setup process is very easy, needing only to setup the rules and message templates once, while the rest will be done automatically by Retargeting. Multitesting and Analytics If you are passionate about A/B testing, Retargeting offers a comprehensive multitesting feature, where you can test any number of message versions that you want. You can make and test multiple message modifications at the same time, in order to determine a winning version based on live results. You can then choose the winning version either manually or you can let the platform make the choice based on the results. Retargeting has also an integrated dashboard that gives you access to key metrics related to your retargeting campaigns. You can easily track the performance of your campaigns and compare the results with your website traffic, from one unified dashboard. Results For live results you can visit this page: https://retargeting.biz/en/live-results Pricing Retargeting uses a performance based pricing. It means that you only pay a commission for the orders generated by Retargeting. Commision tiers are as follows (depending on the total value of the sales generated by Retargeting): Free trial Retargeting offers a 14 days free trial so you can test the app for yourself.
