JavaScript rendering
Whether a page’s content is in the HTML a bot receives, or only appears after scripts run in a browser.
In plain English
Many AI crawlers read the raw HTML and do not run scripts. Content that only loads through JavaScript, like some site-builder widgets, may be invisible to them.
In practice
A restaurant’s menu loads through a script. Google sees it, but an AI crawler sees an empty page.
