Either this one slipped past me or it's pretty new - but I just noticed that some searches (often for a company name) will have a section for "Pages similar to" in the footer... and this is definitely NOT the same as the "Searches related to" block.
As an example, do a Google search for Dow Chemical [google.com] and scroll down. You'll see both "Pages similar to" and "Searches related to"
It looks like this section grabs the first four links that also show up under the light blue "Similar" link right by the company's result - except it skips domains that are also owned byt the company (DowAgro.com in this case).
Anyone done any digging into this search results feature?
