Are sitelinks usefull for a site
 

Google has generate sitelinks for my site www.sexprivates.com will be this usefull for my site will help me to gain rank faster, or dont have so much importance for SERPS?

What exactly do you mean??

As far as I know, sitelinks are links decided by google within your website which they think from they might be useful for visitors, thus showing them in their search pages.

Something like:
yoursite.com
- home
- galleries
- dating
- contact.

For the rest, I doubt there is any benefit from it, except having some additional links under your website(s) in the search engines.

Don't quote me for it though.

Having proper sitewide links should really increase your clickthru's and bounce, conversions, and really just increase the value of all your incoming traffic. Simplest reason for this is the traffic is just more targeted this way.

Imagine a search term like fat dicks. If only the root is listed as number one, you could have straight, gay, male OR female surfers hitting the landing pages. And having half these surfers back out when they see its not a straight site, or not a gay site, or full of black dicks, instead of white ones, etc etc.

So having sitelinks in an instance like this would allow you to target out them clicks, and have your 'gay surfers' going to the gay pages, the black dick surfers going to the black dick pages, hetero males, landing on related pages etc.

I think he means a sitemap.xml and yes, make sure and also create a robots.txt file that points to it as well so that sites that aren't Google can easily find what you have it. All you have to do is put this one line ....
