Feature-detect permission-based APIs and WebGL, and render the content without them

Browser APIs that need user permission, such as location and payments, are not supported when Google renders a page, and WebGL effects are not applied. Google recommends feature detection with polyfills or differential serving, and prerendering on the server for content that depends on WebGL.

Render indexable content first; ask for permissions only after a user action and keep a complete default (for example the full store list) if the request is declined. Wrap WebGL and other optional APIs in feature detection with a plain HTML fallback. Add polyfills for missing APIs the content needs, knowing that some features cannot be polyfilled.
