Why this matters

This check identifies which important content is present in the initial HTML and which requires JavaScript rendering. That distinction helps focus subsequent crawl and rendering investigation.

A STARTING-POINT EXAMPLE

Hypothetical standard operating procedure

Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.

Select several key page templates representing distinct page types on the site.
View the raw HTML source (not browser DOM) of each template's URL.
Search the source for the main H1 heading text and first paragraph visible to users.
Check that internal navigation links appear as <a href> tags in the HTML, not injected by JavaScript.
Flag pages that rely solely on client-side rendering for main content or critical links for remediation.

Watch for

JavaScript pages can be indexed; absence from initial HTML is a dependency to investigate, not proof of an indexing failure.

Definition of done

Record whether each sampled page’s main content and navigation links are present in initial HTML or depend on rendering.
