How do you check content accessibility on a JavaScript site?
Check source HTML, rendered content, links, resources, and HTTP status rather than claiming JavaScript cannot be indexed.

Direct answer
Check source HTML, rendered content, links, resources, and HTTP status rather than claiming JavaScript cannot be indexed. Server or static output can make initial content more dependable, but accessibility still needs verification.
When to use
A page loads content with JavaScript or differs between the browser and Search Console.
Step by step
Inspect the initial response
Check the final URL, status, metadata, body, and scripts for login, location, or robots barriers. Avoid a generic 200 shell for missing content.
Inspect rendering and navigation
Use a browser and URL Inspection to review content, errors, and links. Important content should not depend entirely on user-triggered actions; use crawlable links for navigation.
Reduce fragile dependencies
Provide dependable core content and metadata before enhancement. Test failures and no-JavaScript use, explicitly documenting script-dependent features. Recheck canonicals, 404s, and languages after changes.
Worked example
Hypothetical exercise, not a real performance claim.
A tool may need JavaScript while its instructions, limits, and related guides remain readable in HTML. Script failure should leave a useful explanation instead of an endless spinner.

Pitfalls
Do not present different facts to crawlers and visitors for ranking manipulation. Browser success and search rendering are separate checks.
