95 percent of Germans believe it is important for retailers to know their interests and preferences.¹ You should therefore address your customers personally and directly. To do this, you need new and enriched data that allows you to make targeted decisions based on facts and trends, rather than relying solely on gut feeling or speculation. The art of integrating new data into your own database is called data enrichment. This enrichment process makes your data more useful and insightful and is an important success factor for companies operating in a modern data-centric environment. In this article, you will learn about the other benefits of data enrichment and how you can use it.

Data enrichment: The importance of data enrichment

Data enrichment basically refers to the process of merging new data from third-party sources into your own database. Enriching your own data with external data increases the value of the data. When it comes specifically to enriching customer data, this is referred to as customer data enrichment, while enriching product data is called product data enrichment.

Data enrichment allows you to put information into a new context and give it structure. From there, you can derive exciting insights and use them in e-commerce to improve the customer experience and generate higher sales. A solid database is therefore an important element for the development of AI and thus also for personalization in e-commerce. This is because new data sources are a prerequisite for and provide inspiration to make AI technology even more powerful.

Data enrichment components

Data enrichment encompasses three core aspects:

  1. The purpose of cleansing is to identify and remove outdated, inaccurate, and erroneous values.
  2. Extensions can be used to add new features and specific KPIs. In this context, features refer to characteristics of specific items in the shop environment, such as a customer or a product. Examples of KPIs would be sales or click-through rate.
  3. Completion also makes it possible to improve the data quality of existing features.

Integration into your own database

Data enrichment also poseschallenges for your own database. First of all, new data is simply added and can then be used as KPIs or features in the service applications. If, for example, it turns out that the new KPIs and features are better, they should replace the old ones. In addition, you should delete data that is no longer needed in order to conserve resources and ensure data protection.

Ideally, adding and removing data should not make the schema of your own database more complex. Instead, the new data should be easy to insert into the existing schema and used in the applications without much effort. If this is not the case, you should consider changing your own schema, which would of course involve more effort.

Benefits of data enrichment in e-commerce

The enriched data can be crucial to your success and offers you many advantages:

  • Optimization of data management costs (outdated, unusable data increases the workload).
  • Avoidance of duplicate data sets, resulting in improved data integrity and consistency.
  • Valuable insights thanks to a multifaceted 360° view of the customer.
  • Optimized marketing, perfectly tailored to different target group segments, resulting in improved customer relationships and increased loyalty.
  • Better customer experience and unique shopping experiences thanks to real-time personalization.
  • Increased opportunities for upselling and cross-selling activities through in-depth information about customer interests.
  • Improved KPIs such as sales, leads, and a higher return on investment.

With the help of data enrichment, you can make profitable use of existing information, win over your customers with personalized offers, and set up effective marketing tailored to specific target groups.

Challenges for companies

A major challenge for many online shops when it comes to data enrichment is that the existing data is left to languish in its silos. This means that the data is not connected, but stuck in isolated data silos. Often, the necessary infrastructure to merge data is also lacking. Other problems include conflicting metrics resulting from inconsistent silo data, a lack of customer understanding and thus incomplete customer profiles for a 1:1 marketing approach, and a lack of data-driven processes and access to data, which means that there is no data culture .

Requirements for successful data enrichment

The fundamental prerequisite for data enrichment is integrated data in the form of a solid and reliable database. It is therefore crucial to create a data infrastructure as a starting point for data enrichment. To do this, you extract all data from various systems such as your ERP system, your web analytics tools, your marketing data, product data, etc., and consolidate it in a data warehouse. There, the data is standardized and structured using a data model. The whole thing forms the basis for making holistic decisions. The database can then be used to transfer data to third-party systems and, for example, for email marketing in e-commerce. Transactional data can also be used to optimize and personalize the user experience in the shop.

Data enrichment: Use cases for successful implementation in e-commerce

Use data enrichment to offer your customers an even better shopping experience. E-commerce offers numerous starting points for the successful use of data enrichment. These examples show the possible range:

Enabling omnichannel commerce

If users shop both in a brand's physical store and online shop, both channels can be connected. This is because relevant events also take place outside your shop that can serve as a supplementary data source. With the help of customer loyalty programs such as a bonus program or a customer card , you can collect information in brick-and-mortar stores and use it profitably in your online shop thanks to data enrichment.

In-store purchases are an example of relevant events outside the shop and offer you the chance to complete the most valuable type of event – namely the buy event. It is valuable in the sense that it provides AI with the most relevant information for personalized recommendations, enabling you to deliver tailored recommendations. For example, you can provide your customer with online styling suggestions that match the shirts she last purchased offline. This link optimizes the shopping experience, strengthens brand awareness, and ultimately brand loyalty.

Preventing abandoned purchases

In e-commerce, it's all about preventing abandoned purchases. Imagine if you could remove obstacles from the checkout process step by step. For example, by presetting the default address or preferred payment method based on previous purchase behavior data. This significantly reduces the risk of abandoned purchases.

Minimize returns

Returns are the weak point of every online retailer. Enriched data helps you avoid them and minimize your return rate. The return rate is an important KPI because sales are directly dependent on it. Return data is an important part of purchasing behavior and can provide you, as an e-commerce manager, with information about frequently returned products and reasons for returns, for example.

The product recommendation system can benefit from these new sources of information, as products that are frequently returned should certainly be recommended less often. This means you can exclude goods that are frequently returned from campaigns and exclude items with high return rates from your recommendations. For new customers , you can also feature top sellers with low return rates in your recommendations. In addition, data enrichment allows you to flexibly display information on product detail pages that can help prevent returns, such as details about the fit of a pair of pants. You can enrich this additional information based on the reasons for returns.

If you generally notice a high return rate in certain categories of your shop, you can counteract this by using a product advisor. This also requires data enrichment, or more precisely, an enrichment of product data so that shop customers can select the features they want. In the case of a luggage advisor, as offered on worldshop.eu, the required features would be, for example, what type of wheels a suitcase has, what compartments or what fastenings the luggage has. Especially when the product range is somewhat more specialized, expanding the product features in the sense of data enrichment makes a lot of sense.

Each of the three aspects of data enrichment can significantly improve the quality of such an online product advisor. For example, cleaned data prevents items from being displayed even though they do not match the current feature selection. With the help of completion, you prevent the opposite from happening, namely that suitable items are not displayed. Finally, expanding the data brings the product advisor to life. This gives the customer enough options to choose from, and the features really help them.

Avoid out-of-stock situations and inventory backlogs

Data enrichment also helps you avoid out-of-stock situations by determining stock range based on factors such as current stock levels and historical order and return behavior. This allows you to hide certain products in your shop that may not be delivered on time.

You can also use data enrichment to identify slow-moving items. This allows you to boost sales of these products and avoid stockpiling.

Maximize high-margin sales

Data enrichment also enables you to identify high-margin products and thus maximize your sales. To do this, your data must be enriched with information such as the product's contribution margin, marketing costs, or transactional costs.

Use 1:1 personalization

Also consider the interests of your shop visitors and address each individual customer with 1:1 personalization. Based on previous transactions and interests, customers can be segmented or addressed individually. Use the enriched data in email marketing, for example, to personalize newsletters more effectively. Instead of just using a personal greeting with their first name, you can even customize the entire content of the email, for example with recommendations for their favorite brand, preferred colors, or styles. Information about your customers' interests can also be used for recommendations in your online shop. This will increase the average order value and your sales.
