Google Warns Noindex Can Block JavaScript From Running via @sejournal, @MattGSouthern

Google's update to its JavaScript SEO documentation to clarify that noindex tags may prevent rendering and JavaScript execution, blocking changes, highlights a crucial consideration for website owners. This means that website owners who rely on JavaScript for dynamic content rendering or other essential functions may inadvertently block these features if they use noindex tags on specific pages. This could lead to issues with AI bot traffic, as bots like Googlebot may not be able to execute JavaScript and access the content, potentially affecting website indexing and visibility. To address this issue, website owners can take a few actionable steps: first, review their noindex tag usage to ensure it's not blocking essential JavaScript execution; second, consider using alternative methods, such as robots.txt or meta robots tags, to control crawling and indexing; and third, test their website's JavaScript functionality using tools like Google Search Console to identify potential issues and optimize their SEO strategy accordingly.
