Search Google for your domain name, and if that doesn't work try [seroundtable.com] - you should see ten large sitelinks come up under the main site listing:
Searching for the brand name, such as [search engine roundtable] doesn't return ten sitelinks for me. It only returns the ten sitelinks when I do a domain search.
Do you like this? I mean, domain restrictive search is probably a bit more navigational in nature than searching for a brand name.
I am not sure if this is a test or something everyone sees.
