What each product is
AB Tasty provides A/B testing, multivariate testing, feature flags, personalisation, audience targeting, AI product recommendations, and session replay. It serves mid-market and enterprise e-commerce and SaaS teams that want to optimise conversion rates without relying on engineering for every test. AB Tasty uses a client-side JavaScript snippet for most experiments, with a server-side SDK available for performance-sensitive use cases.
DeepSEOAnalysis audits technical SEO, structured data, and Core Web Vitals — including the specific CWV impact of client-side A/B testing tools like AB Tasty. The AB Tasty JavaScript snippet, when loaded synchronously, can delay LCP and increase INP. AB Tasty experiments that change DOM dimensions without reserving space can cause CLS. DeepSEOAnalysis identifies these experiment-side effects as concrete findings with fix guidance.
When to choose which
Pricing context
FAQ
AB Tasty can affect Core Web Vitals depending on how the snippet is implemented. The client-side JavaScript snippet, if loaded synchronously or early in the head, adds render-blocking time that increases LCP. DOM mutation experiments — where AB Tasty changes element sizes, positions, or content — can cause CLS if the layout change is not anticipated (no reserved space in the original DOM). AB Tasty's server-side SDK eliminates client-side script load entirely, making it the recommended approach for LCP-critical pages. Use DeepSEOAnalysis to measure CWV on pages where AB Tasty experiments are active.
They solve different problems. AB Tasty runs experiments to optimise conversion — it tells you which variant converts better. DeepSEOAnalysis audits technical SEO and CWV — it tells you whether the AB Tasty snippet or experiment variants are degrading Core Web Vitals scores. Both tools are useful for teams running active experiment programmes: AB Tasty drives the CRO programme, DeepSEOAnalysis monitors that the experiments do not introduce SEO or performance regressions.
AB Tasty is used for A/B and multivariate testing of website and product experiences, feature flag management for progressive feature rollouts, AI-driven personalisation (serving different content or product recommendations to different audience segments), and session replay for qualitative analysis. Its primary users are e-commerce and SaaS marketing and product teams that want to run experiments without depending on development sprints.
No. AB Tasty has no public free tier or self-serve trial. Pricing starts around $8,000–40,000+/year. For teams that need lightweight A/B testing without the enterprise price point, open-source alternatives like GrowthBook or lower-cost SaaS options like VWO or Convert are commonly evaluated. DeepSEOAnalysis has a free ungated tier for technical SEO auditing — no account required.
