Once a user opens a web page and accepts the cookies, they get saved on the user\u2019s browser and start tracking the user\u2019s web interactions.<\/p>\n\n\n\n<p>Even after the user exits the website, cookies keep monitoring his\/her activities. In the ad industry, these are used to create elaborated users\u2019 profiles to target ads accordingly. <a href=\"https:\/\/www.adpushup.com\/blog\/behavioral-targeting-for-publishers\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">Behavioral targeting<\/a> becomes possible because of cookies.<\/p>\n\n\n\n<p>Cookies are often sent via publisher\u2019s site. Hence, the publisher is often stated accountable for users\u2019 data, its management, and protection. It\u2019s the responsibility of the publisher to maintain the privacy of users visiting their web pages. <\/p>\n\n\n\n<h2 id=\"h-why-are-cookies-important\"><span class=\"ez-toc-section\" id=\"Why_are_Cookies_Important\"><\/span>Why are Cookies Important?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Web servers have no memory of their own. Cookies are used to make websites remember the users&#8217; action so user is not asked to repeat a task again and again. In short, cookies are used to remember the users\u2019 activities in order to give them a better experience. <\/p>\n\n\n\n<p>For example, if you are shopping online and adding multiple items to your cart, you\u2019d need cookies to remember the items added to the cart. If there would be no cookies, &nbsp;you might have to make each purchase individually.<\/p>\n\n\n\n<p>Similarly, cookies are required for the login process. And to remember the username and password of the user when using the same browser. <\/p>\n\n\n\n<p>To understand the importance, try this\u30fcOpen a web browser and <a href=\"https:\/\/ruinmysearchhistory.com\/blog\/how-to-block-cookies-in-all-browsers\/\">disable<\/a> the cookies on that browser. Now, try to log in to your email account on the same web browser.<\/p>\n\n\n\n<p>You\u2019ll get an error message, asking you to enable cookies on your browser. It was the first party cookies that give you access and ability to log in and use the email account. And unless you enable the cookies loading, you won\u2019t be able to login to any account.<\/p>\n\n\n\n<p>Here&#8217;s how it works for Firefox:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" width=\"1225\" height=\"799\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1.png\" alt=\"Firefox Cookies disabled\" class=\"wp-image-11058\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1.png 1225w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1-300x196.png 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1-1024x668.png 1024w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1-768x501.png 768w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Disabled-1-150x98.png 150w\" sizes=\"(max-width: 1225px) 100vw, 1225px\" \/><figcaption>Firefox cookies disabled<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" width=\"1223\" height=\"739\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1.png\" alt=\"Firefox Cookies Error\" class=\"wp-image-11059\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1.png 1223w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1-300x181.png 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1-1024x619.png 1024w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1-768x464.png 768w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Firefox-Browser-Cookies-Error-1-150x91.png 150w\" sizes=\"(max-width: 1223px) 100vw, 1223px\" \/><figcaption>Firefox Cookies Error<\/figcaption><\/figure>\n\n\n\n<p>When doing the same for Chrome browser, you get:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" width=\"992\" height=\"617\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-browser-cookies-disabled.png\" alt=\"Chrome browser cookies disabled\" class=\"wp-image-11060\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-browser-cookies-disabled.png 992w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-browser-cookies-disabled-300x187.png 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-browser-cookies-disabled-768x478.png 768w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-browser-cookies-disabled-150x93.png 150w\" sizes=\"(max-width: 992px) 100vw, 992px\" \/><figcaption>Chrome browser cookies disabled<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" width=\"1361\" height=\"724\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error.png\" alt=\"Chrome cookies error\" class=\"wp-image-11061\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error.png 1361w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error-300x160.png 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error-1024x545.png 1024w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error-768x409.png 768w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2019\/02\/Chrome-cookies-error-150x80.png 150w\" sizes=\"(max-width: 1361px) 100vw, 1361px\" \/><figcaption>Chrome cookies error<\/figcaption><\/figure>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1669108346122\"><strong class=\"schema-faq-question\"><strong>What are first-party cookies?<\/strong><\/strong> <p class=\"schema-faq-answer\">First-party cookies are just cookies. They work and behave as they are designed to. These are originated from the primary domain visited by the user, hence becoming first-party cookies.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1669108357036\"><strong class=\"schema-faq-question\"><strong>What are third-party cookies?<\/strong><\/strong> <p class=\"schema-faq-answer\">Third-party cookies don\u2019t originate from the primary domain visited by the user. These cookies often result from the services publishers add to make their sites work better (like adding social buttons or chat services or others).<\/p> <\/div> <\/div>\n\n\n\n<h4 id=\"h-we-understand-first-party-cookies-but-why-use-third-party-cookies\">We Understand First-Party Cookies. But, Why Use Third-Party Cookies?<\/h4>\n\n\n\n<p><strong>Ad targeting:<\/strong> For ad industry, <a href=\"https:\/\/www.adpushup.com\/blog\/types-of-ad-targeting\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">ad targeting<\/a> is a huge affair. Third-party cookies are used to gather information on user behaviour such as visited websites, time spends, clicks, geographical location, and more.<\/p>\n\n\n\n<p>This is to create an elaborated profile of the user to show them only relevant ads. Because of this, ads get more impressions and have a better chance of a conversion.<\/p>\n\n\n\n<p><strong>Social buttons: <\/strong>Most publishers add social media buttons to their website. This is to make their platform reach a greater audience. Meaning, if users like what they see on publishers\u2019 page, it can easily be shared using the social button available on the screen.<\/p>\n\n\n\n<p>These buttons come with cookies and track the user events. Even, if users are not signed in to social account on the browser, these cookies would still able to identify them using their online behaviour. And the collected will later be used to show ads on their social accounts.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Also Read<\/strong>: <a href=\"https:\/\/leadsrx.com\/blog\/itp-compliance-cookies-impacted-in-safari\" target=\"_blank\" rel=\"noreferrer noopener\">ITP Compliance \u2013 Stay Ahead of the Cookie Conundrum Curve<\/a><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Third party services:<\/strong> Most publishers nowadays use third-party services like a chatbot. In order to install the chatbot on their platform, publishers are asked to put a code to their websites. This code contains cookies.<\/p>\n\n\n\n<p>The purpose of chatbot cookies is to remember the users and their previous conversations. If users delete the cookies, the chat history and related information will be lost too. <\/p>\n\n\n\n<p>Generally, cookies have an expiration date. Meaning, once installed, cookies automatically delete themselves from the users\u2019 device, after a fixed time interval. Moreover, users can <a href=\"https:\/\/setapp.com\/how-to\/clear-cookies-on-iphone-ipad\" target=\"_blank\" rel=\"noreferrer noopener\">get rid of cookies on iPhones<\/a>, Windows PCs, or any other devices anytime.<\/p>\n\n\n\n<p>Cookies are encrypted form of data to avoid any fraud or data leak. On top of everything, users always have the option to decline the cookies that load on their browsers.<\/p>\n\n\n\n<h2 id=\"h-first-party-cookies-vs-third-party-cookies\"><span class=\"ez-toc-section\" id=\"First-Party_Cookies_vs_Third-Party_Cookies\"><\/span>First-Party Cookies vs Third-Party Cookies<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Here\u2019s an explainer on the differences between the two:<\/p>\n\n\n\n\n<table id=\"tablepress-3\" class=\"tablepress tablepress-id-3\">\n<thead>\n<tr class=\"row-1 odd\">\n\t<th class=\"column-1\">Parameter<\/th><th class=\"column-2\">First-Party Cookies<br \/>\n<\/th><th class=\"column-3\">Third-Party Cookies<br \/>\n<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-hover\">\n<tr class=\"row-2 even\">\n\t<td class=\"column-1\">Origin<\/td><td class=\"column-2\">Originates from main domain opened on users\u2019 web browser<br \/>\n<\/td><td class=\"column-3\">Doesn\u2019t belong to main domain opened on users\u2019 browser<\/td>\n<\/tr>\n<tr class=\"row-3 odd\">\n\t<td class=\"column-1\">Set By<\/td><td class=\"column-2\">Publishers set the cookies to their website using JavaScript code<\/td><td class=\"column-3\">Loaded by third-party servers (eg. ad server) on publishers\u2019 website<\/td>\n<\/tr>\n<tr class=\"row-4 even\">\n\t<td class=\"column-1\">Accessibility<\/td><td class=\"column-2\">First-party cookies work on the main domain (publisher\u2019s website) <\/td><td class=\"column-3\">Third-party cookies are accessible on any website that load third-party cookies code<\/td>\n<\/tr>\n<tr class=\"row-5 odd\">\n\t<td class=\"column-1\">Browser Support<\/td><td class=\"column-2\">Supported by all browsers.
