Google's ad variations beta tool allows advertisers to easily test different variations of ad creative text, such as headlines, descriptions, and URLs. It sets up test variations across accounts and isolates a percentage of traffic to the tests while running normal ad copy for comparison. Google then analyzes clicks, CTR, and conversions to recommend whether tests outperformed the standard ads or if more testing is needed. Early users have seen CTR increases up to 10% and 2x more online conversions through identifying high performing ad variations with this tool.
