In today’s digital era, cookies are a foundational element of how websites function and interact with users. You’ve probably come across the terms “first-party cookies” and “third-party cookies” while browsing websites or managing your browser’s privacy settings. Understanding these cookies and their differences is critical for both individuals concerned about online privacy and businesses aiming to comply with data regulations.
In this article, we’ll explore the key differences between first-party and third-party cookies, their uses, and their roles in the world of personalization, advertising, and privacy.
What Are Cookies in Simple Terms?
Cookies, in general, are small pieces of data stored on your device by websites you visit. They help websites remember information about you, such as login details or preferences, thereby improving your browsing experience. However, cookies have evolved into tools that also support targeted advertising, analytics, and user tracking.
The distinction between first-party cookies and third-party cookies lies in who creates and manages them and how they’re utilized.
What Are First-Party Cookies?
First-party cookies are created by the website that you’re actively visiting. These cookies are primarily used to enhance user experiences by storing key details, such as login credentials, language preferences, or items in your shopping cart. They are considered reliable and less invasive because they operate within the domain you trust and willingly use.
For instance, imagine you’re shopping on an online retail website. A first-party cookie ensures your shopping cart items don’t disappear when you navigate to a different page. Without these cookies, your online experience would feel less seamless, as websites rely heavily on them to personalize your visit.

What Are Third-Party Cookies?
Unlike first-party cookies, third-party cookies are created by domains other than the website you’re directly visiting. These cookies are most commonly used for advertising, cross-site tracking, and analytics. Advertisers embed third-party cookies into websites using tools like ad scripts, which track user behavior across multiple sites.
For example, let’s say you were browsing a travel website for flights. Later, you notice ads for airline deals on unrelated websites. This happens because third-party cookies track your browsing habits and deliver advertisements tailored to your interests. While this technology can be convenient for relevant advertising, it’s also a primary concern for user privacy and data transparency.
Key Differences Between First-Party and Third-Party Cookies
The differences between first-party cookies and third-party cookies revolve around ownership, function, and purpose. Let’s break it down further to illustrate their distinct roles:
1. Ownership and Placement
- First-Party Cookies: Entirely owned and managed by the website you’re visiting. These cookies are saved directly by the domain you’re engaging with.
- Third-Party Cookies: Placed by an external domain that the website has partnered with (such as an advertiser or analytics service).
2. Purpose
- First-Party Cookies: These cookies improve your site experience, like remembering logins or choices you’ve made.
- Third-Party Cookies: Designed for tracking user behavior across websites, especially for targeted advertising and multi-website analytics.
3. Privacy Concerns
- First-Party Cookies: Minimal privacy risks since the information is limited to the website in use.
- Third-Party Cookies: Higher privacy concerns due to their ability to track users across multiple sites, often leading to the collection of vast amounts of personal data.
4. Browser Restrictions
- Modern web browsers like Safari and Firefox have restricted third-party cookies by default, addressing increasing privacy complaints. Meanwhile, first-party cookies remain largely unrestricted due to their trusted role in improving user experience.
Why Are First-Party Cookies Preferred Over Third-Party Cookies?
With online privacy now a major global concern, companies, governments, and individuals have recognized the need to manage cookie use responsibly. Regulations, such as the General Data Protection Regulation (GDPR) in Europe and the California Consumer Privacy Act (CCPA) in the United States, have significantly restricted the use of third-party cookies.
Because of these rules, businesses are shifting towards 1st party cookies for data collection and personalization. By focusing on first-party cookies, companies can maintain user trust while gleaning meaningful insights about their target audiences. This also aligns with companies moving towards “cookie-less” tracking solutions as privacy-first technologies emerge.

Real-World Examples
- First-Party Cookie Usage Example: If you log into your email account, the browser stores a first party cookie to keep you logged in as you check your inbox.
- Third-Party Cookie Usage Example: Say you’re scrolling through a blog, and tracking cookies from an ad network collect browsing data to display shoe ads on another website you visit later.
These examples show how differently both cookie types behave.
Are Third-Party Cookies Being Phased Out?
The digital domain is undergoing a noteworthy transformation. Major browser developers, including Google Chrome, have announced plans to eliminate third-party cookies entirely by the end of the decade. Companies increasingly depend on what are first party cookies for gathering first-hand data while still respecting user privacy. This transition affects advertisers and publishers, requiring them to adopt innovative tracking systems.
Conclusion
Understanding the differences between first-party cookies and third-party cookies is crucial for navigating today’s digital ecosystem. While both serve distinct purposes, first-party cookies stand out for their reliability and minimal impact on user privacy. Businesses adapting to a privacy-focused future are leaning toward cookies that build trust and improve user experiences.
So, the next time you browse your favorite store or see a personalized ad, rest assured that you’re witnessing the intersection of cookies and technology. The debate over first party vs third party cookies will continue for years, but the trend is clear: the digital world is taking privacy seriously.
