I have a few pages that show in the results that I would rather not. Namely a "admin-ajax.php" that appears as "-1" - I downloaded the robot meta plugin and made sure to "no follow no index" all admin pages. I ust did this two days ago so It might be a matter of g00gle not crawling the site to update cache. However, I just inserted a download link via download manager plugin less than 48 hours ago & It already shows up in the search results. How do I prevent this download link from showing up in the serps?
