<meta name="robots" content="noindex"> to a bunch of pages. How long will it take before they're gone? The countdown starts now!
Well it's been a month. So far, Google has removed about 50% of the pages.
Been seeing some pretty significant drops the last few days. At this rate, shouldn't be too much longer before the pages are gone.
Three months later. Fifteen pages to go.
Nine pages to go.
Six pages to go.
Four pages to go.
Three pages to go.
One page to go.
And they're gone!
So it took just about four months to remove the pages.
