Content and metadata are two essential elements that can influence your website's ranking and user experience. Content includes text, images, videos, and audio, while metadata is the information that describes the content and helps search engines and users understand it. To optimize your content and metadata, you should employ some best practices such as using keywords naturally and strategically in your content without overstuffing or spamming. Additionally, write clear, concise, and engaging headlines, subheadings, and paragraphs that capture your audience's attention. Moreover, use <h1> to <h6> tags to structure your content and make it easy to scan. Also, use <title> , <meta name="description"> , <meta name="keywords"> , and <meta name="robots"> tags to create unique titles and descriptions for each page of your website. Lastly, use <img src="" alt=""> and <video src=""> tags to add images and videos to your content with alternative text and captions. Doing so can help your content rank for image and video searches as well as improve accessibility and usability.
