Well, whatever they call those results at the top that are in different text. They are basically "featured results" as far as I am concerned because they appear with the rest of the results (not on the side like all the ads), but they are not normal results.
You mean the ones that say sponsored links? Like the ads on the side that also say sponsored links?
