A WebmasterWorld thread asks how long does it typically take Google to index a brand new web site that has awesome content? 
The webmaster said he has hundreds of unique and useful articles on his new site but Google has still not indexed a single page of his site, even after two weeks.
To me, that sounds like an issue. I’ve seen sites, brand new ones, be indexed and ranking within a day or so. Now those rankings may drop down but the site is indeed indexed within days.
A typical site might take a couple weeks if there aren’t enough quality links pointing to the site. But a quality site with a couple quality links should be indexed fairly quickly in Google. I’d say days but not everyone agrees with me, as you can see in the thread.
