Tracking pixels allows to get all the necessary analytic details and thus is extremely beneficial for advertisers. The tracking or marketing pixels allow cross-platform marketing, tracking the website visitors from one website or a social network to another one and presenting the targeted advertisement on different platforms, devices, or websites.
What Is a Tracking Pixel?
A tracking pixel is a 1x1 pixel graphic, which is usually transparent, hidden, or embedded in the background of a website or email. In other words, it is a tiny pixel-sized image, present in the websites, Cookie Banner ads, or emails, and invisible to the user. A tracking pixel is also called a marketing pixel, or a web tracking pixel.
The tracking pixel code contains an external link to the pixel server. When a user visits a website or opens an email having the HTTP tracking pixel, the HTML code is processed by the user’s browser, which follows the link to the server and opens the pixel graphic. Every time the pixel server gets an inquiry from the browser, it registers the action in its log files. In such a way the server can track website or email user actions and know, which sites the user opened and which other actions were performed.
The following data can be collected and analyzed with a tracking pixel:
- IP address
- Operating system used
- Client’s screen resolution
- Type of device used (mobile or desktop)
- Type of browser or mail program used
- Plugins used.
When the tracking pixel identifies a particular user, the tracking pixel code allows companies to track the following events:
- User behavior on a website, social network, email, or cross-platform activity
- Time the email was read or the website was visited
- Website visits of a user
- Website traffic
- Email opened as digital ad campaigns
- Sales conversions
- The best time of the day and the most engaging audience for the best return of investment (ROI)
- Find out if the user is coming from a paid search on Google, YouTube, Twitter, Facebook, or LinkedIn.
The data, gathered with the tracking pixels, and event tracking allows to create user navigation path, also called a click path. The length of the user navigation path could be used to evaluate the efficiency of the website's services. In an online store, this could show what data is relevant to the user, such as more information about the product range or a longer description.
The length of a user navigation path can also be an indicator of the website's relevance to users and search engines. The longer the user navigation path, the more information is provided to a website user. However, too long a user's navigation path would be disadvantageous to users and search engines alike. A page depth of a maximum of four levels is recommended, which means that the user has to click no more than four times to reach the final page.
The tracking pixels are used by Google Analytics and similar services, which gather data from websites, to tell companies the number of their website’s users and the conversion rate of their digital ad.
Tracking pixels can also be used for the analysis of sent newsletters since they show the opening rates of certain emails or newsletters. By trying different tests, successful marketing campaigns can thus be determined.

How Do Tracking Pixels Work?
The tracking pixels are a powerful tool to acquire and analyze the data. The data acquired can help website owners deliver relevant ads, target the most engaging audience, or provide a better website user experience.
The tracking pixels cannot be disabled from the client-side as easily as cookies can be. In most cases, the website or email users are not even aware of the tracking pixels they are using.
Types of Tracking Pixels
A retargeting, also known as a remarketing pixel, is a tracking pixel that runs when a marketing event occurs (a web page is loaded, an email is opened or an ad is visited), and makes notes of who performed the marketing event and when. Many marketing companies, including Google and Facebook, offer retargeting pixels that you can add to your website or email to use for the retargeting of customers. After the companies make note of the customers who click your links or open emails, then you can retarget your marketing ads to the same customers again. Retargeting pixels, presenting marketing ads just for customers, who have already shown an interest in the ad, produce a better user experience by suggesting relevant content that can impact higher sales and encourage repeat customers.
A conversion pixel is a tracking pixel that is responsible for tracking sales resulting from a marketing ad campaign. The conversion pixel is activated and collects customers' personal data once a purchase has actually been made. Conversion pixels are placed within the code of the order confirmation page or email. Conversion pixels are placed in the marketing ads and thus could be used to measure the conversion rate and thus the success or failure of the marketing campaigns.
Facebook tracking pixel
A Facebook tracking pixel is a tracking pixel that is activated when a customer takes an action after seeing the Facebook ad. For example, when a customer buys something after seeing the Facebook ad, the Facebook pixel is triggered and collects customers' personal data. The Facebook pixel code is placed on your website and ensures that cookies of the website track only customers who interact with Facebook ads and the website.
This tool is used for organizing the Facebook ads and helps to:
- Measure cross-device conversion rates
- Optimize delivery to people likely to take action
- Create a target audience from interested customers
- Remarket the ad to a target audience
LinkedIn tracking pixel
The LinkedIn tracking pixel helps to understand website marketing and sales personnel where visitors are coming from and what they’re looking for. The LinkedIn tracking pixel makes it possible to segment traffic and to see how many click-throughs and referrals come from LinkedIn and how many of them came from other web sources.
Other types of tracking pixels
Tracking pixels, used for performing specific tasks, could have specific tracking pixel names:
- Universal Pixel - a tracking pixel, which tracks website users on multiple pages via a single pixel.
- Landing Page Pixel - a tracking pixel, which tracks the users' landing page on the website.
- Time Delay Pixel - a tracking pixel, which tracks the time delay of a website user's action.
- Postback Pixel.

How to block tracking pixels?
Blocking tracking pixels is more difficult than disabling cookies. However, there are several ways to block the data gathering by tracking pixels:
- Set browser and email settings to be as restrictive as possible, for example, allow external graphics only after permission.
- Block HTML emails in the browser.
- Set up firewall settings to block external graphics or HTML emails.
- Use browser extensions to make tracking pixels visible.
- Surf anonymously with the Tor browser.
- Use proxy servers to block the download of tracking pixels.
- Deactivate the support of scripts in the browsers, which could prevent the collection of data such as browser type or operating system.
However, blocking tracking pixels entirely is not recommended since this can interrupt other functions on the websites.
Differences Between a Pixel and a Cookie
Tracking pixels and cookies are similar in the sense that they both track users' activity and collect personal data, which could serve for marketing purposes. Tracking pixels and cookies are often used simultaneously. However, the differences between them are in how the users' data is delivered and where it’s kept.
A cookie is a piece of code placed on your browser by a remote web server. Cookies are used to store user information for easier login, to increase internet browsing experience, to personalize website content, or to use services such as online shopping. Since cookies are stored on the user's browser, they can not follow users across devices, and they can be enabled or disabled by the user.
Tracking pixels are used to measure the conversion rate of marketing campaigns. They are useful for the analysis of sent emails and newsletters since they show the opening rates of the emails or newsletters.
Tracking pixels allows differentiating between users and computer bots. They also allow the creation of user profiles and navigation paths.
Tracking pixels are also employed by the spammers. They can be placed in spam emails, which helps to find out the valid email addresses. If the recipient opens the email, the tracking pixel is loaded and informs the spammer of the authenticity of the email address. As a result, the spamming traffic increases.
Europe and some states of the USA like California have strict privacy laws, such as GDPR and CCPA, accordingly. Websites must show a Cookie Banner, obviously state that they’re using cookies, and get an implied Cookie Consent, which means that you agree to those terms and conditions. Even the usage of tracking pixels is also regulated by the privacy laws, they collect comprehensive user data, mostly without the knowledge of the user, and it is more difficult for a user to get rid of the tracking pixels and the collection of personal data.
