The question is, if you build out a new section of your website with tons of content – is it safe to just launch them all at once or should you do smaller chunks at a time?
Matt said that Google can handle it either way, but he did say that if a site released hundreds of thousands of pages overnight, it may raise a red flag and warrant a manual review by the Google spam team. And if you do not want Google to manually review your site and you don’t want to draw attention to your site – you may not want to release too many pages too quickly.

Matt said that if you can slowly roll them out in larger blocks but not all of them at once, then do it that way. If not, it should be fine, but someone at Google may manually review it. He also added that it is rare to see a site release so many new pages and for all those pages to all be unique and of good quality. He didn’t say it was impossible.
