What is first party data - OnAudience

What is first party data?

In the digital era, marketers collect first party data to gain insights about their users. It is the data that comes from their own sources, such as app or website. How marketers can benefit from using first party data and what differences are between 1st, 2nd and 3rd party data?

1st party data definition

First party data is the information that companies can collect from their own sources. In other words, every information about customers from both online and offline sources, such as the company’s website, app, CRM, social media or surveys is first party data.

According to eMarketer, 85% of US marketers and 75% of respondents in Western Europe said that increasing their use of first-party data is a high priority. For marketers, it is a really valuable source of users data.

Choosing custom segments for targeting online camapaigns


The first party data can include information as following:

  • demography
  • visited websites & interactions
  • purchase history
  • interests
  • time spent on website
  • and many more

What’s important - first party data can be collected for free and the company which owns the data has all needed customers’ consents. In the GDPR era it is highly important. By using 1st party data, you can deliver your users personalized experiences and display them relevant ads.

First party data is one of the most valuable data, so every company should consider to collect the data and make profits from it. The information is collected for free, which makes it really cost-effective and can be easily segmented and monetized by using a Data Management Platform.

How to use 1st party data

Basically, by using first party data you can deliver your current visitors personalized experience and send them messages they expect. What’s more, you collect high-quality data and be sure that you comply with privacy rules. You can gain all consents, e.g. through your website or app.
Let’s take a look at three benefits of using first party data in company.

1. Create personalized experience

Gathering first party data makes it easy to know your users and divide them into specific groups. You can analyze your web traffic and create audiences who are looking for specific products or are interested in a particular topic, such as sport or automotive. It enables you to create highly personalized messages and increase the effectiveness of your marketing efforts. Read more about audience targeting on our blog. 

2. Comply with GDPR

As we mentioned, 1st party data can be the most transparent because you own it and you are responsible for collecting all necessary consents. Your law department can give you the best instructions what information you should give your users to process their data in compliance with privacy regulations. Basically, users rather agree to process their data by your company because it is usually necessary for making a purchase.

In the age of GDPR, it is extremely important to collect data legally and 1st party data is one of the most trusted and valuable users’ data. Read more about how to process users data and comply with GDPR

3. Get insights about your audience

Collecting first party data gives you a chance not only to store data but also to look deeply into your users’ profiles. By using technological platforms, such as DMP, you can integrate data about your users from various sources (website, surveys, apps, games) to create a full view of your customers. What he or she likes/dislikes? Which products your users wants to buy? Which websites do they visit after leaving your page?

Marketers often enrich their data by external sources (3rd party data), to fill the gaps in their clients’ profiles. For example, if they own only email address, by integrating it with 3rd party data, they can gain knowledge about users’ interests, demography or purchase intentions. It is really useful in planning future campaigns.

How to collect first party data


There are plenty of tools that allow you to collect 1st party data. One of the most popular is google analytics - a tool that helps you analyze your online traffic and gives insights about your customers.

Popular and useful software for managing data is also Data Management Platform. It is a technology that will help you not only gather data, but also integrate it and store on one centralized platform.

By using DMPs you can easily create audience segments and send your customers personalized ads, even if they leave your website. It is a powerful platform to gain knowledge about your users and deliver them a unique brand experience.

First party data vs second party data

Now you know what is first party data and how to effectively use it. So let’s take a look at another type of information - 2nd party data.

In a few words, a second party data is another company’s first party data. It can be sold to you or any other organization and both parties benefit from sharing the data. Firms use 1st part data to reach out to new customers, potentially interested in specific products. This type of data can be gathered via sources, such as:

  • websites
  • mobile apps
  • offline surveys
  • social media channels

Example of second party data can be a flight booking website and car rental company. If the marketers from car rental firm get info about the destination of customers, they can display them, e.g. ads with a discount for renting a car.

The disadvantage of using 2nd party data is the lack of knowledge about data quality. While first party data can be controlled and verified by your company, you don’t know the value of data provided by your partner.

1st vs 3rd party data

Let’s compare 1st party data to the last type of information - 3rd party data. While first party data is the information you collect for free through your own sources, third party data is bought from other companies. There are many data providers on the market that sell information about online customers on global data platforms.

3rd party data includes information such as demography, interests and purchase intentions. Companies use the data, e.g. to fill the gaps in CRM systems. That can help you build a 360-customer degree or target a large user group with specific attributes.

There are many data providers on the market. is one of the world’s largest data warehouses - it provides over 21 B anonymous user profiles from 200 markets globally. To learn more about 3rd party data, visit our Data Exchange page.

1st, 2nd and 3rd - integrating data on DMP

To manage all data from various sources, marketers often use technological platforms that help them organize the data and find insights about online users. Data Management Platforms makes it easy to integrate 1st, 2nd and 3rd party data and create full-view of customers or - if DMP owner wants to use different types of data separately, it is also possible.
