What is Customer Data? What is the Role of Customer Data?
It might be an overstatement to say that today’s business environment has become super competitive, and companies that do not continuously innovate their business operations with data at the core will have to sit on the sidelines as their market is disrupted.
Data technology, science, and processes are rewriting the business rules and driving organizations toward digital transformation. Specifically, customer data plays a crucial role in businesses today. Let’s explore the concept and role of customer data through the article below.
I. What is Customer Data?
Customer data is the information that companies collect from their business and marketing activities to better understand customer preferences and how they use their products.
This information is provided by customers through websites, mobile apps, phone calls, social media, advertising campaigns, and other online and offline channels.

Customer data is defined as information that customers provide when interacting with your business through websites, mobile apps, surveys, social media, marketing campaigns, and other online and offline paths.
Customer data is the foundation for a successful business strategy. Data-driven organizations recognize the importance of this and take actions to ensure they gather the necessary customer data points to enhance the customer experience and adjust business strategies over time.

IV. How to Collect Customer Data
You can collect data from any channel where customers interact with your brand. While there are hundreds of ways to gather customer data, in this section, I will provide the essential methods you can use to gain deeper insights into your customers.
1. Building a Website
Typically, a website will be the main channel through which your customers interact, and from there, you can collect customer data such as demographics, geography, as well as behavioral and interaction data.
Tools like Google Analytics, Mixpanel, Piwik PRO, etc., play a major role in helping you understand preferences, referral sources, conversion details, and their real-time behavior on your website.
While these tools have limitations, such as not collecting qualitative data, you can compensate by using additional testing/visualization tools like Crazy Egg, Optimizely, VWO, and Hotjar. These tools help you understand user behavior through heat maps, session recordings, and visualizing conversion funnels. However, use these selectively, as some tools can be quite expensive.
2. Using Social Media
You can learn a lot about your customers based on how they interact with your personal page on social media. In addition to using basic engagement metrics (such as likes, comments, shares…), you can learn more about your customers by analyzing detailed information from each social media platform.

In particular, with a little effort on online reputation management (ORM), you can not only gather customer data but also gain an understanding of the general sentiment surrounding your brand and services through the content of posts.
Furthermore, you can enhance your customer data collection activities by investing in social media advertising. Through the targeting capabilities of social media platforms, you can continuously experiment until you understand the preferences and other characteristics of your customers.
Especially, by uploading your email list to social media platforms through custom audience features, you can explore their behavior on a specific social media channel to learn more about them and push content to similar customer segments.
3. Using Tracking Pixels
A tracking pixel is a piece of HTML or JavaScript embedded into a website or email that records every visitor to the website or email open. A tracking pixel can record the IP address, operating system, browser, etc., which helps advertisers run appropriate remarketing campaigns.
Through tracking pixels, you can also track customer conversion activities.
4. Contact Information
Contact information is initial data that allows you to maintain a relationship with customers, such as email addresses. You can send emails on topics that customers are interested in, build relationships with customers, and reduce their resistance until they are willing to share more important details like phone numbers.
Most of your customers will not share all their information right away. Choose the longer, more certain approach instead of rushing the process or giving up. Additionally, you can consider offering rewards like gifts or discount vouchers when customers provide their data.
5. Partnering with Customer Data Service Companies
Customer data service companies are a valuable resource for finding customer data. Businesses can partner with these companies to gather customer information and improve the efficiency of reaching out to customers. However, it can be difficult to control the quality of the data you purchase, so additional data filtering steps are necessary before utilizing it.
6. Customer Surveys and Feedback
Customer feedback and surveys are very important in collecting customer preferences, tastes, and opinions. By asking the right questions, surveys can help you gather qualitative data on attitudes.
You can receive feedback on your products, services, sales, and marketing activities through surveys. Net Promoter Score (NPS) is a popular software used for surveys, which helps you understand customer satisfaction with your products.
When designing a survey, consider the following questions:
-
What different data points should you collect?
-
How should you organize the data? What tools will you need to store it?
-
What measures will you take to protect customer data? And are you transparent with customers about how you collect their information?
-
Do you ensure that your data collection methods comply with the laws and regulations of your country?
-
How will you use the data for the benefit of the organization?
V. Analyzing and Processing Customer Data
Customer Data Analytics Tools
To effectively utilize the customer data you’ve collected, you need to use efficient analytics tools such as:
-
Google Analytics: This free tool provides insights into customer behavior on websites and mobile apps.
-
Tableau: A powerful data visualization software that helps create reports and interactive dashboards.
-
IBM SPSS: An advanced statistical analysis tool, suitable for complex analysis and trend prediction.
-
Salesforce Analytics: A solution integrated with CRM systems to analyze customer data within the business context.
The choice of tool depends on the scale of the business, the type of data being analyzed, and the specific goals of the analysis.
Customer Data Analysis Techniques
There are many customer data analysis techniques, ranging from basic methods to complex techniques using machine learning. Some common techniques include:
-
Descriptive analysis: Summarizes and describes the main characteristics of the data set.
-
Segmentation analysis: Divides customers into groups based on shared characteristics.
-
Behavioral analysis: Studies how customers interact with products or services.
-
Predictive analysis: Uses statistical models to predict future customer behavior or trends.
Each technique has its own advantages and is suitable for different analysis objectives.
Data Processing and Cleaning
Before analyzing data, processing and cleaning are crucial steps to ensure accurate and reliable results. This process includes:
-
Removing duplicates: Eliminating duplicate records to avoid bias in analysis.
-
Handling missing values: Deciding how to deal with missing data, such as removing, filling with average values, or using interpolation.
-
Data normalization: Ensuring consistency in data representation, such as date formats and measurement units.
-
Validation: Identifying and addressing outliers or invalid values.
Data cleaning can be time-consuming, but it is an essential step to ensure the quality of the analysis.
By applying appropriate tools and analysis techniques, along with ensuring data quality through processing and cleaning, businesses can gain valuable insights from customer data and make informed, effective business decisions.
