We have a 2000 page city info website and for the last year have been building data such as hotels, leisure facilities, events etc, all geo coded.
We can now produce unique auto generated pages of information for every postcode in the area.
On checking, it means adding twenty fold the number of existing pages and I am concerned we could incur a Google penalty for such a high instant increase in page volume.
My question is:
1. Do we noindex,nofollow and filter them in gradually ie daily
2. Do we index,follow them all in one go
Any advice would be appreciated
