In 2011 we showed how to split traffic between two ad units with different link colours, using a little JavaScript to show each one half the time and custom channels to compare results. That trick is outdated: colour options are gone, and altering ad code is risky. Today AdSense has a built-in Experiments tool that does the split testing for you. Here is how to use it in 2026.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-63557\" src=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments.webp\" alt=\"How to A\/B test AdSense ads with Experiments\" width=\"1200\" height=\"630\" srcset=\"https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments.webp 1200w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments-300x158.webp 300w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments-1024x538.webp 1024w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments-150x79.webp 150w, https:\/\/www.quickonlinetips.com\/archives\/wp-content\/uploads\/ab-testing-adsense-experiments-768x403.webp 768w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<p><strong>Quick answer:<\/strong> In AdSense, open <strong>Optimization &gt; Experiments<\/strong>, create an experiment (for example Auto ads settings, ad balance or blocking controls), choose the site and let Google split traffic between your original and the variation.
