This is a must have tool for authors and website’s owners. Its purpose is to provide a familiar experience to WordPress users. There is no need for any more editing of the files of your theme or plugins for to add custom meta tags. Just add your ID (the meta key “content” value from your verification code) or/and the URL to the social media profile of the publisher in the field on the plugin page and this plugin will do the rest for you. It will automatically add required meta tags to the head section of your website, without changing any of your theme files and without slowing down your website. This is really useful in case of updating theme or plugins, because your meta tags would never be overwritten. Your meta tags will keep on working, no matter how many times you upgrade or switch your theme and plugins.
The plugin works completely independently of the theme, so you can use it with any theme. The meta tags added via this plugin will be entirely unaffected if you edit the contents of the theme’s files, or even completely change the theme.
