Never saw that before, at least not the way it is now. The first result on G SERP is showing also about 12 of its internal, most important pages, separated on two columns. It does Not happen for all keywords, seem to be mostly companies or solid brand names. Also, it is Not happening on Google.COM but only in other Google.ZZZ If that is already common for most of you, well, it was not for me. Attached is an example i got from Steve Pavlina, just came to my mind. The same appears for Capital One, the credit card. However, if you check for GM or Ford Motors, they don't show up, again for example. Will that mean we should build much stronger internal pages?
