When I run a Google search for apache, I see under the Apache's main site some deep links. How can I make Google put deeplinks from my site under my site's name?
These sitelinks (which I assume you're referring to) are generated algorithmically by Google. Factors involved include the age of the site, the relevance to the query, your navigation structure, links to your site, how close the #2 site is to you. Don't worry unduly about these. They're great if you've got them, but there's not much you can do to get them outside of normal SEO techniques. Just keep building back links, and once you become an authority for that search term, they should appear.
Site with sub-links is called 'authority site', which is an unofficial term. I guess Google manually, or maybe by some special algorithm, shows those links. Chose some popular sites, enter their domains in Google, and you'll see that most of them are 'authority sites'. Here are few examples . There is no official explanation about this on Google, someone correct me if I'm wrong. Some reading: Definitions of authority site in Google DP member's site achieved authority status
just in my opinion, i think this is like sponsor link, they pay for it.. just a thinking... iam not sure with it..
Sponsor links are clearly denoted as such and separated from other links. Authority is something what everyone can achieve with building a good site. http://www.digixmas.com/ doesn't have impressive statistics (check with: http://xinureturns.com/ ), but it is authority site.
Boron's right, they're considered to be authority sites by Google (for those particular topics), and there's nothing you can do to get the same treatment unless you put a lot of hard work and elbow grease into making a great site that everyone loves to reference (and recommend to everyone).
I don't mind doing this. I was just afraid it was something I forgot to do. You see, I thought it was something like favicon.ico
they are called sitelinks. you can read the official answer at http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=47334
