Keyword research is the process of finding out what words and phrases people use most to find information online on YouTube. Keyword research can help you optimize your videos for YouTube SEO and Google SEO. You can use tools like [Google Keyword Planner] or [YouTube Analytics] to find out what keywords are relevant to your niche, how popular they are, and how competitive they are. You can also use tools like [Google Trends] or [Answer The Public] to find out what topics are trending and what questions people are asking.

Once you have a list of keywords that you want to target, you need to include them in the title, description, and tags of your video. These are the main elements that Google and YouTube use to understand what your video is about and how relevant it is to the user's query. You should use your main keyword in the title of your video, preferably at the beginning. You should also use it in the first sentence of your description and repeat it a few times throughout. You should also use related keywords and synonyms in your description and tags to cover different variations of your topic.

Thumbnail is a small image of the video that appears next to your video title in search results. Thumbnails can make a big difference in whether people click on your video or not. You should use thumbnails that are clear, colourful, and relevant to your video content. You should also use text overlays or faces to capture attention and convey emotion. You should avoid using misleading or clickbait thumbnails that do not match your video content.

Subtitles and closed captions are the text versions of your video's audio. They can help you reach a wider audience, especially those who are deaf, hard of hearing, or speak a different language. They can also help Google and YouTube index your video content and rank it for relevant keywords. You can add subtitles and closed captions to your videos using YouTube's built-in tools or third-party services like [Rev] or [Veed].

Links and social signals are the indicators that show how popular and authoritative your video is on the web. Links are the hyperlinks that point to your video from other websites or blogs. Social signals are the likes, comments, shares, and views that your video gets on social media platforms like Facebook, Twitter, Instagram, etc. Links and social signals can help you boost your video's ranking on Google and YouTube by showing that your video is valuable, relevant, and trustworthy. You can build links and social signals by promoting your video on your own website or blog, guest posting on other relevant sites, collaborating with other influencers, engaging with your audience, and creating shareable content.

These are some of the tips that can help you promote your YouTube videos on Google and increase your visibility, traffic, and conversions. Remember that SEO is not a one-time thing but an ongoing process that requires constant testing and improvement. Keep creating high-quality content that provides value to your audience and follows the best practices of YouTube SEO and Google SEO
