I've set up a wordpress blog with a whole bunch of scheduled posts so it will roll out as a natural autoblog but my question is this,

Will the search engines index my future blog posts as the date I entered them (ie all at once) or will it only index the posts as they are published.

Cheers.

Depends if you've added the schudled posts to your sitemap.

Search engines will usually index them as they are published (assuming you don't use a Sitemap).
