To optimize video ranking on YouTube, focus on strategic keyword placement in the title, description, and tags. Craft a compelling thumbnail that accurately reflects the content, encouraging clicks. Ensure your video is of high quality and keeps viewers engaged for longer periods, as watch time is a crucial factor for ranking. Utilize end screens, cards, and playlists to guide viewers to more content on your channel, increasing overall watch time. Encourage audience interaction through likes, comments, and subscriptions, and share your videos on social media platforms to boost initial views. Consistent uploading and adhering to a regular schedule contribute to building a dedicated audience over time, ultimately improving your video's visibility on the platform.
