(I'm not asking about the obvious benefits of fresh content for your visitors, I'm curious the effect it has on spiders)
Thanks,

That said, there are some sites that are pretty much set and don't necessarily warrent new work being done. A comprehensive and definitive guide to Shakespeare for example. IF the site has the best content and the best backlink profile and the best onsite SEO in the category, it might stay at or near the top for an indefinite period. In that case, sometimes just a low level ongoing program to encourage new links can be enough.
Basically though, the faster and more clever your competitors are being at generating new content and marketing programs, the more you'll need to do to keep your site ranking well.
