In-app campaigns are designed to enhance the customer experience in the mobile application. Thanks to them, on the one hand, we are able to present personalized products based on the analysis of customers behavior and activities. As a result, you always reach your target group with relevant, personalized messages tailored to each customer’s specific actions. We can also go a step further and give the customer the opportunity to decide for themselves what products they really like and what are their preferences.

One of such actions may be adding a product to your favorites. This activity can be used as a trigger for the campaign which displays the current bestsellers. Based on the swipe mechanism, customer can either like specific product or reject and see another product. In this way, we get to know the customer’s taste and preferences better. The products you show to your customers depend on your business needs. These could be bestsellers, but you can also specify a static group of products or use other type of AI recommendations.

Moreover, products marked as liked or disliked by the customer can be used in further communication with them. You can boost recommendation campaigns results with the liked products or filter the campaigns and exclude products that were disliked. The results of AI campaigns can be used in personalized mailings and in any other touchpoint, ensuring that you show customers only products they really like.

In this use case, we will describe the process of creating an in-app mechanism presenting bestsellers with the swiping system. The campaign will be displayed after the customer adds any product to the favorites. The customer has the option of swiping the products to the right or left and based on the customer decision an event with information that someone like/dislike the specific product is send to Synerise. The mechanism consists of two in-app campaigns: one to display the bar at the bottom of the screen encouraging to display bestsellers, and second one, appearing after clicking the bar, with the proper swiping system.

In-app message example

Prerequisites

  • Implement Synerise SDK in your mobile app.
  • Configure AI engine. Enable Top items recommendations.
  • Implement the product.addToFavorite event in your mobile application. The event must be sent to Synerise after adding any product to favorites by the customer.
  • In Data Management > Events, configure the event actions that your in-app campaign will use to trigger displaying of the swipe mechanism and to send data about liking/disliking a product. In the JS SDK event settings section, you should set the way of authorizing these events to Make this event available to anonymous profiles without JWT. In this use case, the event actions are preferences.action and preferences.trigger.

Process

In this use case, you will go through the following steps:

  1. Create AI recommendations with bestsellers.
  2. Create an in-app campaign to propose the swiping mechanism presenting the bar encouraging to display bestsellers after adding any product to favorites.
  3. Create an in-app campaign to display the swiping mechanism presenting bestselling products with a swipe mechanism after clicking the bar.

Create AI recommendations

In this stage, you will create an AI recommendation campaign which will be used to display products in your in-app message. The customer will have the ability (implemented in the next stage by using an in-app campaign) to express liking or disliking the presented products.

  1. Go to Image presents the Communication icon Communication > Recommendations > Add recommendation.

  2. Enter the name of the recommendation (it is only visible on the list of recommendations).

  3. In the Type & Items feed section, click Define.

  4. From the Items feed dropdown list, select a product feed.

  5. Select the Top products recommendation type.

  6. Confirm the recommendation type by clicking Apply.

  7. In the Items section, click Define.

  8. Click Add slot.

  9. Click the Unnamed slot that was created.

  10. Define the minimum and maximum number of products displayed in the frame according to your needs.

  11. In Static filters, select the availability parameter and set it to is defined, so the recommendations will show only available items.

  12. Optionally, you can use filters to include specific items in the recommendation frame.

  13. Confirm the configuration by clicking Apply.

  14. In the Additional settings, click Define.

  15. From the Sort metric dropdown list, select Sold items count in the last 7 days.

  16. Confirm the configuration of Additional settings by clicking Apply.

  17. Click Save.

Create an in-app campaign to propose the swiping mechanism

In this part of the process, you create an in-app campaign triggered by the product.addToFavorite event. After that, the bar encouraging to display bestsellers is displayed. The campaign lets the customer decide if they want to launch the swiping mechanism with the proposed products. The ready-to-use code presented below generates a custom event (preferences.trigger) after the customer clicks the bar. This event triggers the second in-app campaign, described further in this article.

  1. Go to Campaigns menu icon Communication > In-app messages > Create in-app

  2. Enter a meaningful name for the in-app campaign.

    Important: In the JS code section, replace the CAMPAIGN-ID with the ID of your campaign created in the previous step.

  5. In the Trigger events section:

    1. Click Define.

    2. Select Add event and from the dropdown list, choose the preferences.trigger event.

    3. Click the + where button and as the parameter, choose source.

      Note: If you cannot find the source parameter on the dropdown list, go to Data Management > Events, find preferences.trigger event on the list and add cource parameter by clicking Add property button.

    4. As the logical operator, select Contain and as the value add MOBILE to analyze events only from the mobile application.

    5. Click Apply.

  6. In the Schedule section:

    1. Click Define.
    2. Choose Run immediately option.
    3. Click Apply.

  7. In the Display settings section:

    1. Click Change.
    2. Define the Delay display as 0 and Priority index as 1.
      Note: The mobile application can display one in-app message at a time. If the conditions allow the display of several in-apps at a time, the priority is a decisive factor for displaying the message. The messages with lower priority arenโ€™t queued.
    3. Click Apply.

  8. Optionally, you can define the UTM parameters. Otherwise, click Skip step.

  9. Optionally, you can add the custom parameters in the Additional parameters section. Otherwise, click Skip step.

  10. To start your campaign, click Activate.

What’s next

After the campaign is implemented, the event preferences.action is added on the client’s card. This event has an itemId (product id) and actionType parameter with a value like or hate.

Based on this event, you can create an aggregate with products liked or rejected by the customer. Remember, that before creating an aggregate, you should either have this event already somewhere in your history, or have its definition added in Data Management module in Synerise. Otherwise it will not be available in analysts.

Check how to build this aggregate

  1. Go to Analytics icon Analytics > Aggregates > Create aggregate.
  2. As the aggregate type, select Profile.
  3. Enter the name of the aggregate.
  4. Click Analyze profiles by and select Last Multi.
  5. In the Size field choose how many values you would like to return - in this case it might be 100.
  6. Select Consider only distinct occurrences of the event parameter.
  7. Select the preferences.action event.
  8. Select the itemId parameter.
  9. Click the + where button, and add the actionType parameter.
  10. Choose operator Equal.
  11. Define the parameter value as like.
  12. Save the aggregate.
Configuration of the aggregate
Configuration of the aggregate
Note: To create an aggregate with product rejected by the customer, duplicate the aggregate created above and change the value of the parameter to hate.

Here are some ideas for using the aggregate:

  • You can add such an aggregate to the Boosting section in other recommendation campaigns and enrich the proposed recommendations with products that have been liked by the customer, or to exclude those which they have rejected.
  • You can use the aggregate with the customer’s favorite products and display them as the section on the website or in the cart, as an incentive to buy products that the customer liked and in this way - increase the value of the basket.
  • You can use this aggregate also in the price drop campaign. If the customer does not buy a specific product they liked and its price drops, you can send them this information to encourage them to come back and make a purchase.
  • You can use disliked products in AI search filters, and in this way - exclude those products from the search results.
