Nightwatch is an SEO rank tracker with site auditing and backlink monitoring built around keyword position tracking. StoreVitals focuses on ecommerce technical health — SEO, performance, accessibility, security — with automated scans and alerts.
These tools solve different problems. Nightwatch answers 'where do we rank for our target keywords today?' StoreVitals answers 'is our store technically healthy enough to rank and convert?' Most serious ecommerce SEO teams need both: Nightwatch (or Ahrefs/Semrush) for ranking intelligence, StoreVitals for the technical foundation. Don't use one to do the other's job.
