I was looking for a decent robots.txt solution for my wordpress sites and after some searching I found Yoast's SEO plugin that provides a complete SEO solution including indexation. I set it up it to not index the following pages: search results, login and register pages, all admin pages, date-based archives and tag archives.
However, when I looked at the source of those pages, I couldn't find any meta robots tag except in the login/register page. Is there another way to tell search engines what to index except robots meta and robots.txt? If not, where is the indication to these pages not being indexed?
Thanks in advance
