To stop Googlebot from indexing dynamically generated URLs, you can use a combination of robots.txt rules and meta tags. Disallowing specific query parameters in robots.txt or using the URL Parameters tool in Google Search Console helps control what gets crawled. Also, make sure you're not linking to those URLs internally if they don’t offer unique value.
On a related note, if you're managing media-heavy content or IPTV platforms, many developers prefer tools like download XCIPTV for reliable playback during testing. While it won’t affect SEO directly, a smooth player can help ensure your media content works well before going live.
