Say you have a site with 50K pages, organized in a directory structure. I think there's an older video of Matt Cutts saying that he recommended only launching 5K pages per week as a guideline. But then I think he mentioned somewhere last year that that limit has gone up but I can't remember to what.
What is the best way to gradually launch a 50K directory website for the search engines? What are the alternatives to just uploading all 50 K pages over night and let things play out on their own? Do you gradually unblock the site from the search engines with robots txt? Are there any best practices for what to unblock first in that case?
Wondering because it seems pretty common knowledge that you shouldn't launch too big sites too quickly, but I haven't really seen any specific strategies for this problem
