JavaScript is not an SEO problem by default. The risk appears when essential meaning, links or status depend on a client path that crawlers cannot process reliably.
We inspect the HTTP response, source HTML, rendered DOM and visible interface across representative templates. The comparison identifies missing content, changed metadata, hydration failures and requests that determine whether a page is complete.
Client navigation, filters, infinite lists and application states need stable URL decisions. We test anchor output, response codes, canonical signals and how states are discovered without relying on a person clicking through the interface.
Recommendations reference the relevant rendering mode, component, route or deployment layer. We work with developers to choose server rendering, static output, streaming or client enhancement based on the page's real requirements.
We move from diagnosis to implementation with clear priorities, owners and checks at each stage.
