By accident, I had put <meta name="robots" content="noindex">
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?
I have tried re-submitting my sitemap.xml in Webmaster Tools, but I'm not sure if it works.
Also, if Google will re-index, how long do I have to wait?
