Tube Growth is an app and free website to get more views, likes, and subscribers on YouTube, specifically for YouTube content creators. It's a suite of tools, including a free Chrome extension and app, that is designed to help you grow your audience on YouTube and social platforms like Instagram, Facebook, Twitter, and other major social networks. 

If you have a YouTube channel, you can try out the extension on your mobile browser or on the desktop version of your Chrome browser.

The extension will automatically take the YouTube video URL, and the extension then connects to the website to find out what information is available on that video, what tags are associated with that video, and what kind of keywords are present in that video.

As soon as you find out the information you need, the extension is able to help you with that by providing relevant information for the video such as suggested tags, suggested keyword tags, and suggestions for the video's titles and descriptions.

The website also allows you to generate a report for your channel to view what kind of traffic is associated with your video, what kind of keywords your video is associated with, and how many people viewed your video.
