How do I manage additional META tags for search engine APIs or site verification?

To add additional Meta tags or enter search engine site verification API go to Marketing > Advanced SEO Tools scroll down the page and insert additional tags. These tags will be added just before the <body> tag on all pages.

Example of Google site verification:
Meta name: google-site-verification
