Hello johnny,

Thank you for your question. In SP Page Builder, elements set to “Hidden” are hidden via CSS (using display: none). This means the content is still delivered in the page’s HTML but is not visible to users.

Regarding your concerns:

• Performance / Page Load Time: Hidden elements add some overhead because they are still parsed by the browser. For a few elements, this impact is negligible. However, if you have many hidden blocks—especially those containing images or dynamic addons—it may slightly affect page load times.
• SEO: Hidden content is generally indexed by search engines but does not contribute significantly to SEO unless it is used manipulatively. Regular use for layout or drafts has minimal SEO impact.
• Accessibility: Elements hidden with CSS (display: none) are ignored by screen readers, so they typically do not affect accessibility.
• Frontend Output: There is no visual effect on the live site, but the DOM size increases with more hidden elements, which may affect complex pages.

As a best practice, we recommend using hidden elements for temporary drafts or design variations. For long-term management of multiple layouts or versions, consider duplicating pages, using revisions, or exporting/importing sections to keep pages streamlined.

Best regards
