YouTube has an algorithm that shows videos based on what users like. YouTube is the second-biggest search engine, right after Google, which owns YouTube. So, their algorithms work together. If you make your video rank higher on Google search results, it will also rank higher on YouTube search results. It's a win-win situation. The algorithm looks at how relevant each video is and puts them in order.The algorithm uses many factors to rank YouTube videos. Likes are one important factor. Videos with more likes rise higher in search results. It would help if you had likes on your videos to get your videos at the top of search engine results pages (SERPs).
