Does anyone really know how to improve your chances to having sitelinks indexed?

I think Donald is asking about site links....They are extra links Google has listed below your site that they think may be useful to users.I think from all I have read they are random....Mine seem to come and go.....If you Google my site kanthaidecor.com you will see other links to different pages on my site....I did nothing to make that happen.

Maybe your right. I also the sitemap.xml help bring google to those page by how often you update and information provide threw the sitemap.xml.
as far as those listing when you enter your url it would bring up certain sections of your site that google was in the mood to present.
I believe that the true test of google search was there keyword, url address, descriptions, etc. and not just the internal site map, or the sitemap.xml

@papa.....Many do get confused though about site maps and sitemap xml being two different animals.....And maybe there is a way to help do as Donald is asking but in my searches I have not seen anything as of yet to help with getting site links. ( Delete or Edit for 15 minutes )

lol, papa, I understand that... I provided my sitemap for my customers use. I have already submitted my xml to webmasters. They download it almost on a daily basis which is more often than it use to be. ( Delete or Edit for 15 minutes )

John's answer above is exactly what I was referring to... and I did google it and seen the site links. My question was, what kind of site "structure" does google look for to add those site links? Is there anything I can do to increase the odds of google adding them? Either now or in the future? ( Delete or Edit for 15 minutes )

When I first started using webmasters back in March or April, I did get confused about what kind of sitemap google needs but then someone on this forum helped me and said yola provides the sitemap for us, it's located at sitemap.xml ... but to answer what papa was saying, I know the sitemap visible on my site is not what google downloads. I provided my sitemap so users can easily navigate my site, know all the pages on my site. :) ( Delete or Edit for 15 minutes )

google says "sitelinks are completely automated"
so again google says we will do as we want and we will do it automatically.

we can build all the sitelinks and site maps we want but google will create their own sitelinks.

I read somewhere too... not sure of the source, that google adds sitelinks automatically (randomly) but their "randomly" chosen method is based on a site's structure. There are some sites they CANNOT add sitelinks to because they CAN'T determine what's important to the user's search. In brief, my question was, is there a way to determine if your site is ABLE to include sitelinks. This is probably the best free advertising. Whenever I search google, I look at those sites first because you get the most information of a site directly from the search list. ( Delete or Edit for 15 minutes )
