How long until added to the index?

Its depends on your pagerank and importance of added contents

 

even though your pages are indexed, you'll not be ranked high in SERP. You'll need to wait for months for that, unless you have a very unique topic or niche.

 

Times takes according to your sites backlinks
and fresh material availability

 

and also how much backlinks you have

 

just put any link in any other website , and google will do the rest

if you are using wordpress :
although wordpress is already friendly seo to search engines
you can also use All in one seo pack
+ google xmp sitemap

I've added this two plugins to my wordpress , and the post is indexed within half an a hour something like that

 

I disagree 100%

 

I've heard it takes anywhere from a couple of weeks to a couple of months. Depending on the site.
