For many technical reasons, those numbers are an estimate (they do say "about") and at times they vary quite a bit. With only 1,000 results ever being displayed, the method Google uses to get those numerical estimates from their widely sharded data is a bit of a mystery. Moving more urls into Supplemental could account for some drop, since supplemental urls are only partially indexed.
Anyone else seeing a drop of this magnitutde?
Here are some historical figures on a two-word search I've monitored, taken from screen captures I've saved. Numbers and dates rounded off slightly...
01/20/06 - 20-million
06/15/06 - 90-million
09/30/06 - 20-million
06/30/07 - 30-million
06/30/07 - 30-million
08/15/07 - 33-million
10/01/07 - 2.5-million
Today's figure (and I assume other recent numbers) is dramatically lower. Clearly, Google has been poising for a big update. Not clear whether this is the future or an interim figure.
The "default" Google for my region is showing 5-million. Neither is close to the 30-million neighborhood the phrase has generally been showing.
I haven't determined exact IP for this Google page, but, using the sloppy method of hovering over the cache (and, yes, I know that the cache might be coming from a different IP), I'm seeing 72:14:253:104.
I'm watching the counts for the various ODP domains after the problems of the last few weeks were fixed - now watching the reindexing going on.
It's odd. One IP had shown the counts at treble the others all of yesterday, but that one has now halved... while the others, which were lower, went up by 30% or more.
Something is on the move, and I doubt much can be read into it for a week or two.
