Search engines may ignore content hidden behind accordions if improperly coded. To ensure indexing:
- Avoid display: none and use alternatives like CSS max-height or opacity toggling.
- Ensure the content is present in the HTML DOM at page load.
- Use semantic HTML with clear headings and expandable <div> sections.
- Implement FAQPage schema or other relevant markup for content visibility.
- Test the page using Google’s Rich Results Test to ensure the content is being indexed properly.
