Note Common rel values: nofollow (tells search engines not to follow), noopener (security for new tabs), preconnect (early connection to external origins), canonical (preferred URL).
<meta name="robots" content="noindex, nofollow">
<!-- Use on staging, admin, orprivate pages -->
<meta name="robots" content="index, follow">
<!-- Default behavior, but explicit is fine -->
Note noindex prevents a page from appearing in search results. nofollow tells crawlers not to follow links on the page. For specific bots, use their name instead of robots (e.g., googlebot).
