Meta tags that are important for search engines, which are given by the page, can be viewed in the developer tools by pressing F12. But sometimes they are not easy to find among a huge number of other meta tags, as well as included JS and CSS files. It is much easier and faster to use the meta tag validation tool, which will display only the necessary meta tags that are taken into account when the site is indexed by search engines.
