Large amounts of pages to launch? do it right!

When launching several thousand pages at once on a site, Google and the many other engines can often take ages to spider, index and rank them.

The best approach and strategy is to release them on a timed schedule of a few hundred (2-500 depending on site size, authority, and the amount of content you need to launch). Sometimes its best to fire off (launch) a group of 500 once, then another group a week or so later, another five days later another four days later and so on until the full amount is done.

Google, its seems, is very comfortable with, "this pattern of indexing content and it can actually promote better indexing and rankings more quickly than simply dumping 50,000 new pages in front of the engines." SEOMOZ
