DeepSEOAnalysis vs Quantum Metric

Quantum Metric is an enterprise Digital Experience Analytics (DXA) platform used by large e-commerce companies, financial services firms, and media companies to understand and optimise how users interact with their websites and apps. It combines Real User Monitoring (RUM) for performance metrics, session replay for qualitative user journey understanding, product analytics (funnel conversion, retention, revenue attribution), anomaly detection (identifying unusual patterns in user behaviour that indicate a problem), and A/B test measurement. Quantum Metric acquired Rigor in 2021, incorporating Rigor's synthetic performance monitoring capabilities into the platform. Enterprise pricing; no public self-serve tier.

Rigor was a web performance monitoring company that provided synthetic Lighthouse-based performance testing — similar to Calibre and SpeedCurve but with a focus on monitoring production performance against benchmarks. Quantum Metric acquired Rigor in 2021 and integrated its synthetic monitoring capabilities into the Quantum Metric platform. After the acquisition, Rigor ceased to be sold as a standalone product. Customers seeking Rigor's synthetic monitoring capabilities now access them through the Quantum Metric platform. Synthetic performance tests (Rigor/Lighthouse-based) produce lab measurements that may differ from CrUX field data — which is what Google uses for Core Web Vitals ranking assessment.

No. Quantum Metric's RUM data is collected from sessions where its JavaScript agent runs on your pages — it only measures your instrumented visitor population. CrUX (Chrome User Experience Report) collects Core Web Vitals passively from all Chrome browser sessions on eligible pages, without requiring a JavaScript agent. Quantum Metric's synthetic performance data (via Rigor) is lab-based and may differ from real-user CrUX measurements for the same reasons as other Lighthouse-based tools — different device profiles, simulated network conditions, and clean browser sessions. For understanding Google's Core Web Vitals ranking assessment, CrUX p75 (available in Google Search Console and DeepSEOAnalysis) is the authoritative source.

Different tools for different teams and different problems. Quantum Metric is for enterprise product, engineering, and UX teams at large companies who need to understand user behaviour at scale — session replay, funnel analysis, anomaly detection, A/B test measurement. It typically requires a significant enterprise contract and implementation project. DeepSEOAnalysis is for SEO and marketing teams who need to audit the technical SEO health of pages on demand — CrUX p75 CWV (the Google ranking signal), structured data validity, canonical correctness, redirect chains, hreflang, and AI visibility. DeepSEOAnalysis requires no contract, no snippet, and no setup — instant audit at no cost. They address fundamentally different questions: Quantum Metric asks "how do users behave on our site?" while DeepSEOAnalysis asks "is our site technically healthy for Google and AI search?"
