October 24, 2025Almost every modern web page displays a banner that says something like: “This site uses cookies. By continuing to browse, you agree to the processing of personal data.” Below it — a button, usually “Accept,” often with no real alternative. The pop-up can even block content and negatively affect user experience.
The PSB Hosting team helps you understand the topic from scratch — what cookies are, how they help websites function, which ones are useful, and which may pose security risks. Understanding how cookies work is a fundamental skill for safe and mindful browsing.
Types of Cookies and How They Differ
Cookies are small text fragments that record your digital footprint. A website stores them in your browser’s memory to perform specific tasks. Not all cookies are the same — some are harmless and necessary for site functionality, while others are used by providers to analyze user behavior patterns.
- Technical Cookies
Technical (or essential) cookies cannot be disabled. They ensure the website functions properly — some pages simply won’t work without remembering previous actions. For example, they keep track of items added to a shopping cart, enable secure login to personal accounts, remember session data, and save interface settings like language or region.
These cookies are typically short-term but can also be long-term. Legally, they don’t require prior consent since the site cannot operate correctly without them. - Statistical Cookies
Their main purpose is to help website owners understand how users interact with their site. They collect anonymized and aggregated data — meaning the information isn’t linked to any specific person.
Examples of collected data include: the number of unique visitors, the most popular pages, average time spent on the site, traffic sources, and bounce rates. Analysts use this information to identify weak points, improve navigation and content, ultimately making the website more user-friendly. - Advertising Cookies
These are the most privacy-invasive type. Their main business goal is tracking users for targeted advertising. They remember which products a user viewed, which ads they clicked, and what topics interest them. Based on this, an extensive digital profile of interests is created — later used to display personalized ads.
These cookies are responsible for the so-called “retargeting” effect, when ads for a product you’ve recently searched for appear on completely different websites. - Third-Party Cookies
Third-party cookies are set not by the website you’re visiting, but by external services integrated into it. These may include social media plugins (like “Like” buttons), chat widgets, advertising networks, and analytics systems.
Their main feature is cross-site tracking — they can monitor behavior across multiple websites. This allows advertising networks to build detailed dossiers on users’ habits and interests. Advertising and tracking cookies are most often third-party ones.
What Happens After Clicking “Accept All Cookies”
The instant disappearance of an annoying banner is just the visible part of the process. Technically, your browser receives official permission from the website to activate all previously blocked scripts and store dozens — sometimes even hundreds — of different cookie files. It’s essentially like opening the floodgates for data collection.
The collected information typically includes:
- your IP address;
- device and browser type;
- browsing history on the website;
- estimated geolocation.
Some advanced scripts can even record mouse movements, scrolling speed, and page interaction patterns. This allows sites to create so-called heatmaps, visualizing which areas attract the most user attention.
The gathered data rarely stays with the website owner alone. It’s often immediately shared with third parties — including marketing agencies, data brokers, targeted advertising platforms, and large ad networks. This vast data-sharing ecosystem underpins the business model of many “free” online services.
The real cost of free content isn’t money, but user attention and personal data — which later get monetized through advertising. In principle, providers are required to block all cookies until a user explicitly gives consent, but once you click “Accept All,” your data effectively becomes a tradable asset.
Consent Banners: The Design Trap
Interface designers know a simple truth — the easier it is to take an action, the more likely users will do it. That’s why the bright, high-contrast “Accept All Cookies” button is always placed in the most visible spot. Meanwhile, options like “Customize” or “Reject” are often hidden as dull gray text links. This is no accident — it’s a deliberate design choice meant to nudge users toward the option most beneficial to the website owner.
To streamline compliance, entire platforms such as Consent Manager and Cookiebot exist. They automatically generate cookie banners, store records of user consent as proof, and block scripts until permission is granted. Using such tools helps companies stay legally compliant.
Failure to follow these regulations can have serious consequences. Under the GDPR, regulators can fine companies up to 4% of their global annual revenue. Russian law also protects internet users — it requires data operators to obtain explicit consent before processing cookies or collecting personal data. And that’s where the legal aspect of cookie use begins.
Legal Framework: GDPR, ePrivacy, and Russian Regulations
The General Data Protection Regulation (GDPR) in the European Union sets strict, user-centric standards for handling personal data. Its guiding principle is valid, informed, and explicit consent. This consent must be specific — given for clearly defined purposes — and unambiguous, meaning no pre-checked boxes, silence, or mere website use can qualify as agreement.
A website visitor must take a clear affirmative action, such as clicking “Accept.” Just as importantly, they must have an equal and straightforward option to refuse data processing. If accepting cookies takes one click, rejecting them should require no more effort.
The ePrivacy Directive, which complements GDPR, focuses on rules for electronic communications. Its key requirement is prior consent before storing or accessing any information on a user’s device. This includes cookies, local storage, and similar technologies.
Exceptions apply only to cookies strictly necessary for communication or the direct provision of a requested service — for example, a shopping cart cookie or session authentication in a personal account.
In Russia, the legal foundation is built around the Federal Law “On Personal Data”. It obliges data operators to obtain prior user consent before processing personal information. Usually, this consent is formalized through an online offer (оферта) — the user accepts it by a single action such as registration or continued site use.
Practical Use of Cookies by Websites
Content personalization is the most visible function of cookies for users. News and media platforms analyze behavior patterns — which articles were read, how long they were viewed, and which ones were skipped — to dynamically shape the user’s feed, suggesting topics and materials that are most likely to capture interest.
Online stores take this personalization even further, creating the feeling of a one-on-one experience. They greet users by name and use browsing and purchase history to recommend related products, accessories, or similar models. This creates the illusion that the store “understands” the user and their preferences — a strategy that significantly increases the likelihood of purchase.
Advertising mechanisms have reached exceptional precision. It all starts with a simple search query — say, for “trips to Bali.” From that moment, specialized tracker cookies, often third-party ones, begin their work. They record your interest and transmit it to advertising networks. Then follows remarketing (or retargeting): for days or weeks afterward, banner ads for flights, hotels, and tours to Bali appear across multiple, seemingly unrelated websites.
This happens because the ad network, recognizing your cookie identifier, deliberately serves you relevant ads across the web, with one clear goal — to bring you back to complete an unfinished purchase.
Analytics, powered by cookie data, forms the foundation for digital product development and business growth. These data provide invaluable user feedback in their natural environment.
Website owners can see exactly on which page users lose interest and close the tab, which buttons attract the most clicks, and which elements go unnoticed.
This objective insight helps inform decisions about redesign, navigation improvements, content optimization, and overall user experience. In the end, it leads to the creation of more intuitive, efficient, and user-friendly websites and applications.
The Other Side: Risks and Misuse
Cybercriminals can intercept cookies through man-in-the-middle attacks. By stealing a cookie — for example, via public Wi-Fi — an attacker can impersonate a user and gain full access to their account without ever knowing or cracking the password. This type of attack is known as session hijacking.
A less technical but far more common risk is aggressive profiling. Years of detailed activity tracking enable advertisers and data brokers to build not just a digital, but almost a psychological portrait of a person. Such dossiers often include a user’s interests, fears, financial situation, family status, and consumer habits — information that can later be used for manipulation, targeted advertising, or even discrimination in pricing and offers.
Managing Your Digital Footprint
Now we come to the key question — how to control what you agree to online. When you see a cookie banner, look for the “Settings” or “Customize” option. You have every right to allow only essential or analytical cookies while disabling all tracking-related ones.
Some permissions can also be managed directly in your browser settings. The “Privacy and Security” section often lets you automatically block tracking activity. Performing a regular cleanup of cookies and browsing history is a form of digital hygiene — simple but effective — and it can be done right from that same menu.
You can strengthen protection even further with browser extensions. Ad-blockers, for instance, include built-in anti-tracking filters that block most intrusive scripts. Moreover, using Incognito or Private mode automatically deletes all temporary files once the window is closed. Privacy-focused browsers with enhanced configurations block trackers by default.
Clicking “Accept All” may be quick — but it’s not free. The cost is a partial loss of privacy and the transfer of large amounts of behavioral data. Understanding the different types of cookies and the tools available to control them empowers you to move from being a target of surveillance to being an active manager of your own data. And if you’d prefer to delegate digital protection, the PSB Hosting team is always ready to safeguard your online privacy.
