If you google IBM or any major company - within the SERPs - under the listing of IBM - you'll see "products", "Contract", etc.

Just wondering why Google allows that and how any site can get that type of listing.

Google Sitelinks, google creates them automatically. I dont know how they go about picking which sites have them prob high traffic, great content, etc...

You can also remove these.. for more info check out google's webmaster tools

thanks guys.

Google itself decides for importance of links for searchers. You can see that in google webmaster account

No one exactly knows why some websites has Sitelinks and some other dont have. Its a question for most webmasters .

Their are some internal Algo which creates it, but you can check in Google webmasters tools whether its is created for your site or not

That happens automatically,you too can have it if your site has a high pr,great content and large number of visitors.

I assumed it happened to all large high profile sites, never really took much notice but it changes them quite often on dynamic sites, just had a look at mine, pretty weird how they decide what to show, one of them is "Tesco great promos on laptops." Can't imagine that thread is taking the world by storm.

It is Google Sitelinks. I think google can pick out the websites which have big traffic, unique content, good site architecture.
