The process of executing a page's code to produce the final content a crawler or browser sees.
Rendering is the step where a browser or search engine runs a page's HTML, CSS and JavaScript to build the fully constructed content and layout. Search engines render pages to see content injected by JavaScript, but rendering is resource-intensive and can be deferred, meaning content that depends on client-side execution may be seen later or missed. Ensuring critical content and links are present in the initial HTML reduces reliance on rendering and improves reliable indexing.
