A decision checklist for making JavaScript product sites fast, crawlable, canonical, and understandable.
Render the answer reliably
Important copy, headings, canonical metadata, and navigational links should be available in the rendered response without depending on an interaction. Server rendering or static generation is useful when it reduces failure modes, but the test is the output: can a crawler and a low-powered device receive the meaningful page consistently?
Treat every indexable route as a document
Each route needs a descriptive title, a useful summary, one canonical URL, a coherent heading structure, and content that fulfills its promise. Parameter combinations, filters, and legacy paths should not create competing versions of the same answer.
Give interaction code a performance budget
Animation and client state should communicate the product rather than delay its content. Measure loading, responsiveness, layout stability, and real-device behavior, then remove unnecessary hydration and third-party work from the critical path. Technical SEO and product experience are often the same engineering decision viewed from different sides.
