It is a form of <a href=\"https:\/\/www.adpushup.com\/blog\/conversion-optimization-publishers\/\" target=\"_blank\" rel=\"noreferrer noopener\">conversion rate optimization<\/a> test (CRO test) wherein two versions of a particular element are exposed to a section of live traffic to identify which variation will drive more conversions. In simple words, the A\/B split testing identifies the better-performing variant based on audience interaction data.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>A\/B testing has been fully utilized in digital marketing. Be it ad copy, newsletters, or ad creatives, it has made the decision-making process more streamlined.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>When we talk about split testing for publishers, we specifically highlight the processes that are frequently implemented by publishers. This can include <a href=\"https:\/\/www.adpushup.com\/blog\/best-ad-placement-strategies-on-your-website\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad placements<\/a>, choosing the <a href=\"https:\/\/www.adpushup.com\/innovative-ad-formats\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad formats<\/a>, and website content presentation among other things.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Now that we have discussed what is A\/B testing, let&#8217;s explore examples to understand it better.<\/p>\n\n\n\n<h3 id=\"h-examples-of-a-b-testing\">Examples of A\/B Testing<\/h3>\n\n\n\n<p>A\/B testing in digital marketing is an industry-wide phenomenon.

Hence, if you have any doubts, you can simply A\/B test it and let the audience guide you towards the decision.<\/p>\n\n\n\n<h3 id=\"h-data-driven-decisions\">Data-driven Decisions<\/h3>\n\n\n\n<p>A\/B test strictly operates on data, i.e., it will present the data in the form of user engagement, <a href=\"https:\/\/www.adpushup.com\/blog\/how-to-increase-cpm\/\" target=\"_blank\" rel=\"noreferrer noopener\">CPM<\/a>, and other metrics to clearly demarcate the better-performing variant.

Through this, they can shape a content roadmap that aligns with the audience\u2019s interests.<\/p>\n\n\n\n<h2 id=\"h-3-limitations-of-current-a-b-testing-software\"><span class=\"ez-toc-section\" id=\"3_Limitations_of_Current_AB_Testing_Software\"><\/span><strong>3 Limitations of Current A\/B Testing Software<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The majority of the A\/B testing software is not made for publishers. Here\u2019s why:<\/p>\n\n\n\n<h3 id=\"h-can-t-track-ad-clicks-to-measure-results\">Can\u2019t Track Ad Clicks to measure results<\/h3>\n\n\n\n<p>Since most of the ad networks include the creatives in the form of an iframe, A\/B testing software is unable to track ad clicks. Not to forget it is also a program policy violation for many ad networks to measure ad clicks directly using any analytics or testing software.<\/p>\n\n\n\n<h3 id=\"h-no-support-for-creating-variations-automatically\"><strong>No Support for creating variations automatically<\/strong><\/h3>\n\n\n\n<p>A\/B testing ads can be slightly more complicated as the number of variations rises exponentially. Typically, you would want to show 3 ad units on a page, and you have 6-7 key spots, 2-3 important ad sizes for each location, and 5-6 color themes for each spot.<\/p>\n\n\n\n<p>The number of variations would easily reach 100s, and there is no reason why creating variations should not be automated. Of course, creating a very large number of variations is only advisable for large publishers.<\/p>\n\n\n\n<h3 id=\"h-manually-editing-code-does-not-help-either\">Manually Editing Code does not help either<\/h3>\n\n\n\n<p>Even if you manually create the new ad code (which you want to compare the control with), say in <a href=\"https:\/\/www.adpushup.com\/blog\/10-ways-you-can-optimize-adsense-for-more-revenue\/\" target=\"_blank\" rel=\"noreferrer noopener\">Adsense<\/a>\u2018s Ad Management panel, you can\u2019t just edit the HTML code of the variation inside popular A\/B testing tools (most of them are client-side). This will not work.<\/p>\n\n\n\n<p>This is because A\/B testing tools (again, the client-side ones) push the updates\/changes (which you made) on the page after the page loads.

You test one single element and keep all other variables intact to get accurate results. In simple words, the key to precision in A\/B tests is choosing one aspect at a time. By doing this, you can isolate the effect of each modification and make changes accordingly.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>For example, if you want to test <a href=\"https:\/\/www.adpushup.com\/blog\/mobile-ad-sizes-formats\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad sizes<\/a>, then just stick to that. Keep all other variables the same &#8211; be it the ad format, ad placement, copy, creative, and even the stack.<\/p>\n\n\n\n<h3 id=\"h-do-not-rush\">Do not Rush<\/h3>\n\n\n\n<p>This point is important from a data-collection point of view. It is recommended to wait till you have at least 1000 monthly website visitors before you get into split testing. While it\u2019s not a hard-and-fast rule, having a small sample size can skew your results, which can render the test inconclusive or even invalid.<\/p>\n\n\n\n<h3 id=\"h-conduct-a-b-tests-across-devices\">Conduct A\/B Tests across Devices<\/h3>\n\n\n\n<p>Your audience can access your website from any device. Hence, it makes absolute sense to conduct the test across multiple devices (laptops\/mobiles\/tablets). Through this, you can identify any device-specific user behavior and optimize the user experience accordingly.<\/p>\n\n\n\n<h3 id=\"h-monitor-performance-continuously\">Monitor Performance Continuously<\/h3>\n\n\n\n<p>While performing A\/B tests, keep yourself updated with the ongoing results, preferably on a daily basis. If you notice variation significantly underperforming, be ready with a mitigation plan or terminate the test.<\/p>\n\n\n\n<h3 id=\"h-keep-external-factors-at-bay\">Keep External Factors at Bay<\/h3>\n\n\n\n<p>A\/B tests require a stable environment with no external interruptions that can disrupt the test flow or skew the performance data. Hence, ensure that website changes or marketing campaigns do not influence the test in any way. A word of advice: it\u2019s better to put a hold on the ongoing changes while performing the test to get precise results.<\/p>\n\n\n\n<h2 id=\"h-a-b-testing-statistics\"><span class=\"ez-toc-section\" id=\"AB_Testing_Statistics\"><\/span>A\/B Testing Statistics<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>1. <a href=\"https:\/\/truelist.co\/blog\/ab-testing-statistics\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">TrueList<\/a> states that:<\/p>\n\n\n\n<p><\/p>\n\n\n\n<ul><li>The global A\/B testing software market is expected to reach $1.08 billion by 2025.<\/li><li>A\/B testing statistical significance can be reached with a minimum of 5000 unique visitors.<\/li><li>Simple subject lines receive 541 percent more responses than creative ones.<\/li><\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>2. According to <a href=\"https:\/\/llcbuddy.com\/data\/a-b-testing-statistics\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">LLCBuddy<\/a>,<\/p>\n\n\n\n<p><\/p>\n\n\n\n<ul><li>A\/B testing is used by 60% of businesses for landing pages, and 63% say it is easy to execute.<\/li><li>77% of marketers use A\/B testing, with 60% using it on landing sites, 59% on emails, and 58% on PPC.<\/li><li>Bing reported that using A\/B testing on display ads resulted in a 25% increase in ad revenue.<\/li><li>Obama&#8217;s digital team had utilized A\/B testing in 2019 to increase contribution conversions by 49%.<\/li><li>According to Hubspot, after an A\/B test, emails with the sender&#8217;s real name received 0.53% more opens than emails with the sender&#8217;s business name.<\/li><\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>3.

This happens primarily because your layout develops <a href=\"https:\/\/www.adpushup.com\/blog\/banner-blindness\/\" target=\"_blank\" rel=\"noreferrer noopener\">banner blindness<\/a> over time.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Continuous MAB testing is the perfect solution. Creating a leading indicator of change in the user behavior towards ad units isn\u2019t a difficult task which can help keep ad units performing well all the time.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>In a non-technical language, once you start the experiment on your website, continuous optimization and MAB will continue serving the majority of your impressions to the best-performing variation. However, as soon as the system notices a (statistically significant) drop in the CTR, the system will find the best possible variation itself.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>It is also technically feasible to use machine learning to find the best spot for your advertisements (outside the defined variations) and change it as the user behavior changes.<\/p>\n\n\n\n<h2 id=\"h-key-takeaways\"><span class=\"ez-toc-section\" id=\"Key_Takeaways\"><\/span>Key Takeaways<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>What is A\/B testing:<\/strong> It is a technique where two variants of an element are exposed to live traffic to identify the conversion-driving variant.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>What can publishers do with A\/B testing:<\/strong> Optimize ad placements, compare ad formats, optimize content layout and UX, and evaluate different ad networks\/SSPs, among other things.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>Benefits of A\/B testing:<\/strong> Smarter and data-driven decision making, more optimized content strategy that aligns with the audience, and significant SEO gains.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>Limitations of A\/B testing for publishers:<\/strong> Can\u2019t track ad clicks to measure results, no support for creating variations automatically, and no help with manual coding.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>Best practices of A\/B testing:<\/strong> Test one element at a time, don\u2019t A\/B test with a small sample size, conduct split test across multiple devices, and continuously monitor the performance.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>Multi-armed Bandit Solutions (MAB):<\/strong> It is a more refined form of A\/B testing that utilizes machine learning to divert traffic to the high-performing variant than its counterpart.
