Cookies

What are cookies and why do they matter?

Cookies are small text files stored in a user’s browser when they visit a website. They help websites remember information such as login details, language preferences, shopping cart contents, or browsing behavior. 

Think of cookies as memory tools for digital experiences. Some are essential for a website to function properly, while others help marketers understand behavior, personalize content, and measure performance across campaigns. 

A good example is a financial institution offering online services. If a visitor selects a preferred branch, logs into a secure area, or starts filling out a form, cookies can help preserve that session and create a smoother experience. At the same time, marketing cookies can help teams understand which campaigns drive engagement and where users drop off in the journey. 

What are cookies used for? 

Cookies support a range of website functions, from basic usability to more advanced marketing and optimization. At the most practical level, they help websites remember user activity and preferences, keep users logged in, save form progress, and support personalization. They are also widely used for analytics, allowing teams to measure visits, page views, engagement, and campaign performance. 

Different cookies serve different purposes. Essential cookies are required for core site functionality, while preference cookies remember settings such as language or region. Analytics cookies help organizations understand how users interact with a site, and marketing cookies support targeting, retargeting, and advertising measurement. 

In platforms like Xperience by Kentico, this kind of behavioral insight becomes even more valuable because it can support personalization, consent-aware tracking, and more informed marketing decisions across the customer journey. 

What are the main types of cookies? 

A website will usually use several kinds of cookies depending on its goals and compliance requirements. Session cookies are temporary and disappear when the browser is closed, while persistent cookies remain on a device for a defined period so a website can recognize returning visitors. First-party cookies are set by the website the user is visiting, whereas third-party cookies are set by external tools such as ad platforms or analytics providers. 

Each type plays a different role. Essential and first-party cookies often support usability, security, and performance, while third-party cookies are more often associated with advertising, tracking, and cross-site profiling. 

Why are cookies important for digital experiences? 

Cookies help businesses create smoother and more relevant digital interactions. Without them, websites would struggle to remember user preferences, maintain sessions, or measure how content and campaigns perform over time. 

They also make personalization possible. Cookies can help a website recognize returning visitors, tailor content based on past behavior, and reduce friction by remembering choices users have already made. This leads to a better user experience, stronger analytics, and more effective optimization. 

Are cookies always necessary? 

Not all cookies are strictly necessary. Some are essential for a website to work, while others are optional and mainly used for analytics, personalization, or advertising. 

Essential cookies are usually needed for tasks such as logging in, securing forms, remembering consent choices, keeping items in a cart, and supporting site navigation. Non-essential cookies are more likely to be used for tracking campaign performance, measuring user behavior, personalizing content, delivering targeted advertising, or running A/B tests. 

For simplicity, cookies are often described as a way for websites to remember users, but their role can range from basic functionality to advanced marketing and optimization. 

Which types of organizations rely most on cookies? 

Nearly every organization with a website uses cookies in some form, but their importance increases with digital maturity. A simple brochure website may only need essential cookies for usability and security. By contrast, organizations with more advanced digital strategies often rely on cookies to support personalization, lead generation, ecommerce, marketing attribution, customer journey analysis, and multistep forms or logged-in experiences. 

For growing businesses, cookies help connect content delivery with customer insight, making them a foundational part of modern digital marketing and user experience. 

How do cookies support personalization?

• Cookies help websites recognize returning visitors and remember context from previous interactions.
• They make it possible to show more relevant content based on past behavior.
• They can remember preferences such as language or location.
• They support personalized recommendations for products, content, or resources.
• They reduce repeated actions for returning visitors, creating a smoother experience.
• Without cookies, many personalized experiences would need to depend on account logins or would not be possible at all.

How do privacy regulations affect the use of cookies? 

Privacy regulations have changed how businesses use cookies, especially non-essential ones. Cookies are no longer just a technical website feature; they are now also part of privacy, trust, and digital governance. 

Organizations need to think carefully about consent, clear cookie notices, data retention, third-party tracking, and regional compliance requirements. As a result, cookie management has become a more visible and strategic part of digital operations.
