These cookies can provide information to their owner about an internet user&#8217;s online activities, such as which websites the user have viewed or actions they have made while using a website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cookies can be used in a variety of ways. In certain circumstances, they remember a user&#8217;s behavior or preferences on a specific website, allowing the website to offer functionality like keep a user&#8217;s shopping cart populated between visits or allowing forms to autocomplete with user data. Cookies with these purposes are almost unanimously considered as a beneficial use of visitor data that benefits all parties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cookies can also be used to track online user behavior in order to support personalized marketing. These are generally called &#8220;affiliate cookies&#8221;.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose you&#8217;ve ever noticed advertisements or links to third-party articles that look uncannily relevant to your previous online activity while reading an online article.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this case, this could be the consequence of a web cookie tracking your behavior. While essential to modern digital <a href=\"https:\/\/www.scaleo.io\/blog\/how-to-grow-your-ecommerce-brand-through-affiliate-marketing\/\" title=\"How To Grow Your eCommerce Brand Through Affiliate Marketing?\" rel=\"dofollow\" >marketing and eCommerce<\/a> methods, such cookie usage is contentious since a sizable portion of users believe these approaches violate their privacy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-difference-between-first-party-cookies-and-third-party-cookies\">What is the difference between first-party cookies and third-party cookies?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A first-party cookie<\/strong>&nbsp;is associated with the domain that installs it on the user&#8217;s browser. This allows the website\/cookie owner and the user to communicate information &#8220;one-on-one&#8221;. Amazon, for example, installs first-party cookies on visitors&#8217; browsers to save their shopping cart status (and, of course, for various other reasons too).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A third-party cookie<\/strong>&nbsp;is coming from a different domain other than the one you are using, and installing cookies on the user&#8217;s browser. This domain is frequently a service provider or a business <a href=\"https:\/\/www.scaleo.io\/blog\/partner-marketing-software\/\" rel=\"dofollow\" >partner<\/a> of the installing domain. The third-party domain then has access to the user&#8217;s data.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"724\" src=\"https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2021\/09\/1-EuT_9qPbsVpJ_mT51BLXzQ-1024x724.jpeg\" alt=\"-\" class=\"wp-image-4151\" title=\"-\" srcset=\"https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2021\/09\/1-EuT_9qPbsVpJ_mT51BLXzQ-1024x724.jpeg 1024w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2021\/09\/1-EuT_9qPbsVpJ_mT51BLXzQ-300x212.jpeg 300w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2021\/09\/1-EuT_9qPbsVpJ_mT51BLXzQ-768x543.jpeg 768w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2021\/09\/1-EuT_9qPbsVpJ_mT51BLXzQ-1536x1086.jpeg 1536w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Affiliate cookies deployed by online advertising service providers such as Xaxis and Tribal Fusion on their clients&#8217; sites are common examples of third-party cookies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While some advertisers, publishers, and web users see third-party cookies as fundamental to the internet&#8217;s monetization and operations, others see them as a threat to online privacy. There is truth on both sides of this debate, which has left key digital giants such as Google, Apple, and Firefox with a difficult question to answer: what should be done about third-party cookies?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-key-differences-between-first-and-third-party-cookies\">Affiliate cookies 101 (and why they still matter)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Affiliate cookies store referral context (click IDs, partner IDs, timestamps, landing pages) so you can credit a conversion. They\u2019re usually <strong>first-party<\/strong> (set by your domain during a partner-referred visit) or <strong>third-party<\/strong> (set by an external domain embedded on your site). First-party is resilient and consent-friendly; third-party is fragile across modern browsers and risky without explicit user choice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We prioritize:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>First-party cookies<\/strong> with sensible expiry (e.g., 7\u201330 days for last-click programs; longer only with clear consent).<\/li>\n\n\n\n<li><strong>Server-side event collection<\/strong> so cookie values sync to a secure backend, not leaky front-end scripts.<\/li>\n\n\n\n<li><strong>Consent strings<\/strong> aligned to your regional rules (EEA\/UK\/CH require explicit consent for non-essential storage; CPRA requires an opt-out for \u201cselling\/sharing\u201d).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What changed since 2023?<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>\ud83e\udded <strong>Area<\/strong><\/th><th>\ud83d\udd04 <strong>Then<\/strong><\/th><th>\ud83d\ude80 <strong>Now<\/strong><\/th><th>\u2705 <strong>What you should do<\/strong><\/th><\/tr><\/thead><tbody><tr><td>\ud83c\udf10 Third-party cookies<\/td><td>\u201cGoing away\u2026 soon.\u201d<\/td><td>Blocked by Safari\/Firefox; user-controllable in Chrome<\/td><td>Treat 3P cookies as <em>bonus<\/em>, not baseline.

We rely on <strong>first-party parameters<\/strong>, <strong>server-side events<\/strong>, and <strong>cryptographically signed postbacks<\/strong> that match your consent posture. You get durable measurement across Safari\/Firefox\/Chrome, consistent payouts partners can trust, and fewer compliance headaches. Clean. Predictable. Scalable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You don\u2019t need nostalgia\u2014you need proof. If you run affiliate programs on first-party cookies, server-side events, and a consent posture you can defend, you\u2019ll pay the right partners and sleep at night. If you cling to third-party shortcuts, you\u2019ll keep reliving the same reconciliation drama. The playbook is straightforward: keep cookies minimal and first-party, mirror every critical value to the server with signatures, publish attribution rules that match your cookie TTLs, and wire fraud controls that make tampering expensive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Where does this leave you? With leverage. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You control the data you collect, the promises you make, and the receipts you can show. You can run \u201ccookieless\u201d when you must, and cookie-light when you can. And if you want fewer surprises, we\u2019ll say it plainly: move more of the journey server-side and use cryptographically signed postbacks so arguments end on facts, not screenshots. We built Scaleo\u2019s cookieless tracking, dual-rail attribution, and unified event ledger for exactly this reality\u2014so you and your partners see the same truth and optimize the same week. That\u2019s the game now: clear rules, clean signals, and an audit trail that earns trust. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do you need a cookieless tracking solution and are ready to make that your default?<\/p>\n\n\n\n<div class=\"wp-block-cover\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\"><\/span><img loading=\"lazy\" decoding=\"async\" width=\"1792\" height=\"1024\" class=\"wp-block-cover__image-background wp-image-15456\" alt=\"-\" src=\"https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo.png\" data-object-fit=\"cover\" title=\"-\" srcset=\"https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo.png 1792w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo-500x286.png 500w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo-768x439.png 768w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo-1536x878.png 1536w, https:\/\/www.scaleo.io\/blog\/wp-content\/uploads\/2024\/01\/the-future-of-igaming-affiliate-marketing-trends-and-software-innovations-scaleo-900x515.png 900w\" sizes=\"auto, (max-width: 1792px) 100vw, 1792px\" \/><div class=\"wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow\">\n<p class=\"has-text-align-center has-large-font-size wp-block-paragraph\"><strong>Experience the effectiveness of Scaleo first-hand by signing up for <a href=\"https:\/\/www.scaleo.io\/igaming\" data-type=\"link\" data-id=\"https:\/\/www.scaleo.io\/igaming\" rel=\"dofollow\" >a free trial<\/a>. <\/strong><\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Cookies have been an important part of the internet since the mid-1990s, but some examples of this technology may soon fade into internet history.&nbsp; Today, we will examine the most recent plans to phase out third-party tracking cookies, including a Google initiative to replace intrusive tracking technology with a new set of APIs.
