VWO (Visual Website Optimizer) is a leading conversion-rate optimization platform — it provides A/B testing, multivariate testing, heatmaps, session recordings, surveys, and personalization. StoreVitals is automated ecommerce health monitoring — it audits the technical foundation of your store (SEO, security, performance, accessibility, structured data) so the experiments VWO runs are built on a healthy, conversion-ready store.
VWO is the conversion-rate optimization platform of choice for serious ecommerce experimentation programs — if your team is running 5+ active tests at any time, validating product changes with statistical rigor, and personalizing experiences for different visitor segments, VWO (or peers like Optimizely, AB Tasty, or Convert.com) is mandatory infrastructure. StoreVitals does not compete with VWO on experimentation depth; we run zero A/B tests. Instead, we ensure the store underneath those experiments is technically healthy — that LCP regressions aren't tanking your control variant, that missing canonicals aren't fragmenting your traffic, that accessibility violations aren't excluding visitors from your sample. Most growing ecommerce brands use both: StoreVitals to maintain the technical foundation, VWO to optimize what happens on top of it. The tools answer different questions: VWO asks 'what variation converts better?' and StoreVitals asks 'is the technical store healthy enough that the answer is trustworthy?'
