I am building a new site that I know will end up around 200,000 pages when I am done. The domain is a few years old but there was never more than a couple of pages on it. The site is being built dynamically and the content should be unique. That said, I am concerned that if I launch the site immediately with all 200k pages, Google may think I am trying to spam them and never allow the site and all the pages to get indexed. So I am attempting to do a delayed release, and grow the pages exponentially over time. Does anyone have experience with this? I would really like some guidance on how long to delay and how many pages to release at once. Please feel free to PM me or post to this thread. Thanks in advance for the help.
The real question is what the 200K pages consist of, and do you actually need that many. If it is a forum and these are threads then fine, but if it is spam scrapped from article directories then I wouldn't bother. Either way there is no hard or fast rule about whether google will judge it to be spam. However my experience with websites is that google likes organic growth and gets suspicious about overnight websites, that appear content ready. Hope it works out for you, but my suggestion wuld be to focus on quality rather than quantity
A delayed release of 200k pages could take you a long time. If your website isn't spammy then just let it rip.
What he said. It really matters what these 200k pages consist? if it's repeated information or copied then it's no good. if it's unique content, blogs, forum discussions, wiki pages then yes it is useful. Google will take a while to index them.
If your website is not spammy, then do not worry about how fast you create the pages. Google will index the pages according to it's own time.
