Title

• Keep it short and sweet - A meta title should be around 60-70 characters in length, as anything longer may be truncated by search engines.
• - Make it relevant - The meta title should be reflective of the page's content, as this is what will help users decide whether to click through to your page or not.
• Use keywords wisely - Use relevant keywords in your meta title to help improve your page's search engine ranking. However, don't stuff your title with keywords as this will likely have a negative effect.
• Keep it unique - Each page on your website should have its own unique meta title. Don't use the same title for multiple pages, as this can be confusing for users and search engines alike.

Description

• First, keep your meta descriptions short and to the point. They should be no longer than 160-180 characters(As per Google there is no limit of Meta description.), as this is the maximum length that will be displayed in Google search results.
• Second, make sure that your meta descriptions are relevant to the page they are describing. They should accurately reflect the content of the page, and be written in a way that is both informative and interesting.
• Finally, don't stuff your meta descriptions with keywords. This will not only make them less effective, but can also result in search engines penalizing your website. Instead, focus on writing natural, informative, and interesting descriptions that will appeal to both users and search engines.
