I have a question about google site links. If you search for "trade show displays" on google, the site #1 and site #4 have site links, but none of the others do. I thought only the top sites got site links. Why don't #2 and #3 have site links if #4 does? I've seen it on searches besides "trade show displays", but obviously thats what I'm interested in.
Just to update this, now a google search for "trade show displays" shows site links for results #3 and #4, but not for the #1 or #2 results. I'm wondering if it's a function of the website and not the position, and that certain websites if they are in the top 4 will get site links, but others won't when they're in the top 4? But that doesn't see to always be the case... for example, when this
website about trade show displays makes it into the top four, sometimes it shows site links and sometime it doesn't?
Maybe it's a bug? Maybe its intentional to keep us confused? Is this just another google mystery, or does anyone know why???
