Google expanded Sitelinks

Hello friends, i got to know that Google expanded his sitelinks to 12. You can find the details below. I am not a SEO expert and i can't understand this fully. Can any one please tell me dose it affect old sits? What steps we need to take while building a site considering this sitelink expansion. Thanks in advance.

You pretty much have no control over whether your site appears with sitelinks and whether your are a site that has 12 vs. 6 sitelinks appear is also out of your control.

I would suspect Rule #1 to ever get 12 sitelinks would be to actually have... 12 pages on your site that all provide value!

Other than that focus on your linkbuilding and content the site provides and if you are actually providing something of value Big G might one day shine down on your site and shower your with site links.

Sitelinks also would update accordingly for old sites - its generally old and established sites that have sitelinks in the first place.

I just noticed the extended site links, check out these ones, look massive!

I hate the look of it

yeah takes up load of serp real estate. However, think it will hugley benefit people who have them in position 1.
