YouTube Likes Ratio is a free Chrome extension developed by quackadoodledoo. As a useful proxy for the old like:dislike ratio, this extension shows the percentage of viewers who liked a video, providing an insight into viewer sentiment.

With the removal of the dislike count and the like/dislike ratio, YouTube Likes Ratio fills the gap by calculating the percentage of viewers who liked a video. This feature gives users an idea of how well-received a video is and allows them to gauge viewer sentiment. By providing this information, the extension helps users make informed decisions about the content they choose to watch on YouTube.

Overall, YouTube Likes Ratio is a valuable tool for those who want to gain a quick understanding of viewer sentiment without the need for a like:dislike ratio. It is easy to use, free, and enhances the YouTube viewing experience by providing relevant information at a glance.
