Easily set up a split test between Refinery89’s Single Tag and a third-party tag. This guide provides a script for running A\/B tests on your website. This script ensures that once a visitor is assigned to either Refinery89 or another party’s solution, they will consistently be assigned the same solution for the duration of the test (for default 30 days).<\/p>\n

Copy and paste the following code block into the <head> section of your website, as high as possible to ensure the ad stack initializes before other page elements.<\/span><\/p>\n <\/p>\n <\/p>\n This script ensures user-level persistence via cookies, preventing provider switching during a session. This results in cleaner performance data and maximized revenue by maintaining a stable monetization environment for every visitor.<\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n The methodology is applied as follows:<\/p>\n User A is monetized randomly by provider A or B<\/strong><\/p>\n Example 1 \u2013 50\/50 Split<\/p>\n <\/p>\n Example 2 \u2013 70\/30 Split<\/p>\n <\/p>\n During the whole session the User will be monetized through the same solution<\/strong><\/p>\n <\/p>\n <\/p>\n","protected":false},"featured_media":0,"parent":9875,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","doc_tag":[],"class_list":["post-15747","docs","type-docs","status-publish","hentry"],"yoast_head":"\n<script>\r\n\/* A\/B testing script - loads either Refinery89 or competitor script\r\nEdit the 4 variables below and paste this in your site's head*\/\r\n(function () {\r\n\/\/ ===== CONFIGURATION =====\r\nvar R89_SCRIPT_URL = \"https:\/\/tags.refinery89.com\/yoursite.js\";\r\nvar OTHER_SCRIPT_URL = \"https:\/\/example.com\/other-script.js\"; \/\/ Replace with competitor URL\r\nvar COOKIE_DAYS = 30; \/\/ Days to keep user in same variant\r\nvar SPLIT = 0.5; \/\/ Percentage for R89 (0.5 = 50% each)\r\n\r\n\/\/ ===== DO NOT EDIT BELOW =====\r\nfunction _ab_getCookie(n) {\r\nvar m = document.cookie.match(new RegExp(\"(?:^|; )\" + n + \"=([^;]*)\"));\r\nreturn m ? decodeURIComponent(m[1]) : null;\r\n}\r\nfunction _ab_setCookie(n, v, d) {\r\nvar e = new Date(Date.now() + d * 864e5);\r\nvar f = \"; SameSite=Lax\" + (location.protocol === \"https:\" ? \"; Secure\" : \"\");\r\ndocument.cookie = n + \"=\" + v + \"; expires=\" + e.toUTCString() + \"; path=\/\" + f;\r\n}\r\n\r\nvar _ab_v = _ab_getCookie(\"ab_variant\"), _ab_e = _ab_getCookie(\"ab_exp\");\r\nvar _ab_url = new URLSearchParams(location.search).get(\"ab_variant\");\r\nif (_ab_url === \"r89\" || _ab_url === \"other\") _ab_v = _ab_url;\r\n\r\nif (!_ab_v || !_ab_e || Date.now() > parseInt(_ab_e)) {\r\n_ab_v = Math.random() < SPLIT ? \"r89\" : \"other\";\r\n_ab_setCookie(\"ab_variant\", _ab_v, COOKIE_DAYS);\r\n_ab_setCookie(\"ab_exp\", String(Date.now() + COOKIE_DAYS * 864e5), COOKIE_DAYS);\r\n}\r\n\r\nif (document.querySelector('[data-ab-test]')) return;\r\n\r\nvar _ab_s = document.createElement(\"script\");\r\n_ab_s.async = true;\r\n_ab_s.src = _ab_v === \"r89\" ?
