How Fast Is Too Fast to Increase Page Volume of Your Site

[ioV]

I am working on a project that is basically a site to list apartment for rent (similar to apartments.com or rent.com). We want to add a bunch of amenity pages, price pages, etc. Basically increasing the page count on the site and helping users be able to have more pages relevant to their searches and long tail phrases. So an example page would be Denver apartments with a pool would be one page and Seattle apartments under 900 would be another page etc.

By doing this we will take the site from about 14,000 pages or so to over 2 million by the time we add a list of amenities to every city in the US. My question is should I worry about time release on them? Meaning do you think we would get penalized for launching that many pages overnight or over the course of a week? How fast is too fast to increase the content on your site? The site about a year old and we are not trying to scam anything just looking to site functionality and page volume. Any advice?

Sometimes you see a bit more organic (in terms of people just naturally linking to things) indexation of content if pages are dynamically generated by a user selecting the amenity, location, etc, and then the database creates the page on the fly and then someone links to that.  Still it's nice to have a bit more control over page URLs  and give them a bit more established, static presence ahead of time.

I wouldn't worry about their release in regards to amount.  Just make sure they function, have sitemaps indicating the new content, and try to drum up a press blitz on the new amount of pages in social and conventional space. Google does well with large increases if it sees a correlated increase in search or press.
