Google has updated its guidance regarding JavaScript-based paywalls to address challenges in how Google detects paywalled content. The update highlights that some JavaScript paywalls deliver the full content in the server response but use JavaScript to hide it until the user's subscription status is confirmed. This method is unreliable for restricting access. Sites using JavaScript paywalls should ensure that full content is only provided after confirming subscription status, helping Google accurately identify which content is paywalled.
