Link: Supplemental goes mainstream
Color me pessimistic.
Google claims that since the gap between the main Google index and the dreaded “Supplemental Index” is now so narrow, there is no reason to continue labeling results from the Supplemental Index as such. This all sounds fine and good (despite the lack of actual data), but it just seems a bit off. Many (if not most) SEO specialists believe the “Supplemental Index” is the equivalent of the kiss of death. Thus, “going Supplemental” is not a good thing, and the complaints about this abound.
It sounds like Google is tired of hearing the complaints, and is just hiding the fact that some results are supplemental. Does this announcement really mean anything? No, it just points out the fact that supplemental results will no longer be labeled.
Fishy? I think so.
