3rd Party Cookies. What Are They? Are They Going Away?

What are Third-party cookies?

Third-party cookies are created by the domain that is not the website you are surfing. These are typically utilized for online advertising objectives and installed on your website by attaching scripts or tags. Third-party cookies can reach by any website that loads the code of the third-party server. Online promotion is the most well-known use of third-party cookies. By attaching tags to pages that may or may not display ads, sponsors can follow users (or devices) on multiple websites they surf.

For example, when you hit a news break website, that website generates a first-party cookie and place it on the website. Because it is a source of news similar to multiple other journalist websites, They use ads produced by different websites that perform third-party cookies and save them on your machine.


Types of cookies:

There are three kinds of cookies:

  1. First-party cookies are in the related domain you are presently entering. Consequently, if you are using example.com, all cookies saved in this domain are recognized first-party cookies. These cookies identify users within pages, memorize picked settings, and online store or shopping carts. You unusually find websites that are not utilizing first-party cookies.
  2. Second-party cookies are a different topic. Some may declare that it does not exist. Second-party data is frequently first-party data distributed among associates. In this way, second-party cookies are just a component of the data associated with cookies.
  3. Third-party cookies are cookies saved in another domain than you are currently surfing. These are essentially applied to follow users over websites and present related ads over websites. Another excellent example is the assistance chat feature given by a third-party service.

Are third-party cookies secure?

Similar to first-party cookies, third-party cookies do not have a significant influence. In reality, cookies are not dangerous and do not affect your machine with viruses or malware. But, third-party cookies may be considered a privacy gap for some consumers. That has produced new privacy regulations like GDPR and CCPA, providing users extra authority over which cookies track them.

How to clear cookies after each session?

If you want to dump cookies at the end of each session, select one of the following in your browser settings:

  • Chrome: Keep only local data until you quit the browser
  • Firefox: Clear history when Firefox closes
  • Internet Explorer: Delete browsing history when exiting

If you do not select one of these settings, the browser retains cookie data between sessions. In other words, those ads that tempt you on your vacation would not go away so quickly. Emails that look random at first glance are not random. Suppose you visit the website that created your login ID. They probably have your name, email address, and perhaps your phone number and address. You may be visiting a website that uses third-party cookies & you may not know it. One of the cookie notification failures is that you often do not specify the type of cookie used on your site. They can be first party, third party, or both. However, if your website has ads (often), you can reasonably expect your website to generate both first-party and third-party cookies.

To find out if a particular website uses third-party cookies, try the methods described below in this article, or visit cookie-script.com and enter your web address in the home page bar.

How are third-party cookies created?

The way to create a third-party cookie is if the website you are visiting requests a third-party service. Let say you have an integrated chat on your website example.com. To make it work, example.com requires a script from its chat service provider. someservice.com.

The script looks like this:

<script src = “https://Example.com/js/chat.js”> </ script>

That says “Go to someservice.com to get this live chat JavaScript file”. In reply, the browser receives a JavaScript file containing “Chat” and optionally a cookie placed in the browser by the someservice.com domain. Before you notice, before the chat window appears, your browser already stores a third-party cookie from a random website you never visited. Third-party cookies are not limited to JavaScript files only. Requests to another domain can bring third-party cookies (scripts, images, fonts, CSS files, etc.) to your browser.

Are Third-Party Cookies Useful?

Since the late 1990s, online marketers have built their businesses based on the ability to track online users and target them with advertising. Many use third-party cookies. The two largest online advertising companies, Google Ads and AdSense, make legitimate claims that third-party cookies are useful for consumers because they create ads according to their interests. After all, if you are forced to see ads, it is better to see ads related to your interests. Online ads may revert to content-targeted ads when third-party cookies are gone. In other words, it is an ad that targets a specific population based on the website you are visiting, similar to how you run a magazine. Because targeted advertising is far more valuable, major advertising platforms may find other ways to track users across websites and remember previous search history.

Termination of third-party cookies

With the passage of CCPA, ePR, and GDPR, the government is working to defend the privacy claims of website users. These rules and regulations require civil and criminal punishments for neglecting to notify users of the presence of cookies.

Third-party cookie days are limited, demand from regulators and customers has directed several in the tech industry to demonstrate that third-party cookies (and the targeted promotion they make) will shortly end. Safari on Apple and Firefox on Mozilla now prevent third-party cookies by default. One well-known resister is Google Chrome, which operates 67% of the browser business share.

Google has a meaningful stake in third-party cookies. Approximately 90% of Google revenue attains from advertising. Without third-party cookies, its advertising power can be unfavorably affected. That is one of the purposes why the group assumes that it has delayed the default block of third-party cookies till 2022. Until then, the organization has utilized actions to decrease some of the more invasive features of third-party cookies using the SameSite tool.

Third-party cookie alternative

There is a bit of a resolution that may compensate third-party cookies as the business standard for digital marketing. Two are distinct and under progress, and two are current methods and have new importance.

  1. Google Privacy Sandbox

In 2019, Google published the Privacy Sandbox. That is an ambition to meet customer expectations for enhanced privacy on the web.

It uses a tracking system named Federated Learning of Cohorts (FLoC). Alternative to using third-party cookies to gather data about your browsing records, we examine an online venture in your Chrome browser.

Google Chrome uses that data to allow users to a (cohort) of people with related interests and choices. Chrome addresses that data to the domains that use FLoC.

Google is working to discuss these and other matters in a recent answer to a regular study by the UK Competitive Markets Authority (CMA). Google has implemented this collection of promises accordingly.

  1. Universal ID

Structures similar to Unified ID 2.0 (UID 2.0) promote the business of individual user IDs for all Internet users. This solution keeps the advertiser capacity to serve relevant, targeted ads, but with more commands available to users.

  1. Content-targeted advertising

Content-targeted ads put ads based on-page content for keyword and topic-based targeting moderately than behavior tracking.

Content targeting provides marketers enhanced control over where their ads appear so that these sites coordinate your brand value. You cannot arrange that utilizing third-party cookies.

Of course, the scope of content-targeted ads will be more conservative. Target viewers can only view your ads when they visit a site that has related content.

  1. Other first-party data collection

If 88% of the marketers examined rate it first preference this year, all have now encouraged to step up their data collection.

First-party knowledge is more valid and secure, permitting you to produce a more targeted user experience than third-party data.

It is essential to spend in good old digital marketing techniques such as content production and email marketing. By developing stronger connections with your clients, you make valuable insights and information that your consumers are willing to give.

First-party information is beneficial to both individuals. Users do not demand to compromise their privacy for help, and marketers can go behind the basics. In other words, customers can relate to the goods and services they want.

Let me explain. No, there is too much. Let me sum up – Indigo Montoya

Third-party cookies are code objects created by a separate domain that is not the website you are surfing. They are normally uses for online advertising objectives and installed on your website by attaching scripts or tags and can  reach by any website that loads the code of the third-party server. As they are not opt in marketing elements, they have been derided as privacy endangering. With the passage of new legislation, like CCPA, ePR, and GDPR, the government is making them hard to employ and a few alternatives are popping up.
