Using descriptive tags are an important element of SEO for YouTube videos. To get a good ranking on YouTube, you should use descriptive tags that are relevant to the content of your video. Make sure to include your targeted keywords in the tags, and vary them to include related words. For example, if your video is about “how to make a pizza”, your tags should include words like “pizza“, “recipe“, “cooking“, “Italian cuisine“, etc. This will help your video to appear in more relevant search results and get higher rankings on YouTube.
