SEOTesting is a platform for running SEO A/B tests and tracking SEO changes to identify which page changes increase clicks, impressions, CTR, and conversions. Launched in 2016, it uses Google Search Console and Google Analytics data.

SEOTesting helps SEOs validate hypotheses and monitor site-level performance through evidence-based workflows. The platform offers time-based testing to compare performance before/after page-level or site-level updates, and SEO split testing using defined test and control URL groups for more controlled evaluation. An LLM testing feature tracks shifts in GA4-reported sessions from large language model interfaces. The tool is designed for SEO agencies, in-house teams, and consultants. Beyond the main platform, SEOTesting offers free SEO tools to validate XML sitemaps, extract sitemap URLs, generate XML sitemaps, check meta titles, and validate canonical tags.
