How long does it take to reindex the website

[Coraltoes77]

Generally speaking, how long does it take for Google to recrawl/reindex an (ecommerce) website?

After changing a number of product subcategories from 'noindex' back to 'index', I regenerated the sitemap and have fetched as Google in WMT.

This was a couple of weeks ago and no action yet.

Second question: Does Google treat these pages as if they're brand new?  I 'noindexed' them back in April, and they were ranking ok then.

(I had noindexed them on the back of advice from my SEO, due to concerns about these pages being seen as duplicate content).

Help!

Coraltoes, in the case of sites and pages with minimal authority, it can certainly take a month or more URLs to show they've been updated in the index--it will happen eventually, though.  Your newly removed-from-noindex pages will not be seen as new pages as the URLs, themselves, are already known to google and the noindex tag doesn't delete Google's knowledge or the crawling of them--it just eliminates the URL's visibility in the index.

Thanks Chris, yes, that's a good point that Google still has knowledge of these pages.  At least that's one positive.  I guess I will need to be patient.

Thanks very much.
