Indexing: Control how search engines handle a page
Meta Robots Index
This setting tell search engines like Google to add this page to their index and list them in search results. If you want your page, pick "index". If you do not want this page to be included in search results, pick "No Index".
Meta Robots Follow
This setting tells Google and other search engines to either follow or not follow the links on the current page. Search engines work by crawling a site and exploring all of the links on a page. In some cases, you may want Google to not index a page but still follow the links. Or you may prefer to not index the page along with ignoring the links.
