title: How to get Google to re-index a page after removing noindex metatag?
body: <p>By accident, I had put <code>&lt;meta name="robots" content="noindex"&gt;</code> into lots of pages on my domain. I have now removed this meta-tag, but how can I get these pages to be re-indexed by Google? Any tip?</p>
  
  <p>I have tried re-submitting my sitemap.xml in Webmaster Tools, but I'm not sure if it works.</p>
  
  <p>Also, if Google will re-index, how long do I have to wait?</p>
