SEO A/B Testing made simple, accurate, and scalable

Every SEO strategy revolves around one key question: “Will this have a meaningful impact?”

Lumenlab’s SEO A/B testing platform helps you confidently answer that question. Our data driven testing approach empowers you to measure the true impact of your SEO optimizations before you roll them out site wide, accelerating growth, removing guesswork, and significantly boosting your ROI.

SEO A/B testing (also known as SEO split testing) compares the performance of two statistically similar groups of pages, like product or category pages, to pinpoint exactly which SEO changes lead to measurable organic improvements. By applying targeted SEO adjustments to just one group (the variant) and leaving the other unchanged (the control), you gain clear, actionable insights to drive meaningful results.
