Why are HTML meta tags important?
Meta tags describe the unique value of a page. Without meta tags it would be impossible to accurately describe what the content on the web page is actually about, meaning that the page cannot be indexed well by search engines.
For example, you can create a unique page by inserting a descriptive title and a meta description in the HTML page. You can ensure a clear and unambiguous registration of the page in the search engine by placing a canonical meta tag. And to create a graphic representation of the website, a favorite icon (favicon.ico) meta tag is added.
