Google index cap – 1 result for “Twin towers are no more”

Some weeks ago I read Rand Fishkin’s post about Google capping its index and retiring a lot of old content. I didn’t think any further about that topic until I was writing my monthly column for APC Mag (April 2010). I was checking some search counts for some old news and found the numbers a bit low. So I thought I’d try some truly big news stories, taking care to choose a phrase most likely to be used only for the next 24 hours and not some recent coverage:

  • Princess Diana dead” = 397,000 results. Phrase match. OK, so the web was a lot smaller in 1997, so this might be OK.
  • Michael Jackson dead” = 29.8M results. This is more like it. Maybe there were more Diana stories and the search cap theory is true?
  • 2004 tsunami = 10.9M results in Google. Broad match. Yahoo7 shows 54.2M results. Bing shows 3.14M results.

Then the puzzler:

I had missed the terrible tragedy by going to bed (in Australia) just five minutes before the first plane hit, but I woke to the clock radio newsreader opening with “The twin towers are no more”. It took me a few seconds to absorb this apparently bizarre news bulletin and subsequently I heard that phrase many times that day. Surely, numerous print media also used it, so I am puzzled to find just 31 instances today in Google.

Bing is not a lot better – we are used to Bing counts being a tiny fraction of Google’s for a given search term:

Yahoo:

Finally, an unambiguous phrase, not date-restricted (there are lots of these namesake buildings around the world), spelt the American way to avoid counting many of the others:

Google:

Yahoo:

Bing:

Is Google becoming more relevant or pruning the index? I tend to think it’s the latter. Is this Caffeine?

Feel free to share...After Mr Donald Trump became the president at noon today (USA EST), many reported that the whitehouse.gov website removed references to Climate Change and LGBT. That isn’t entirely accurate. The website up to that point has been archived and can be found at https://obamawhitehouse.archives.gov/. The LGBT URL was https://www.whitehouse.gov/lgbt but it redirects […]

    those are some very pertinent points. But honestly I watched a lot of CNN during that time, it was around 7 in the evening and I watched CNN continously for hours. But I really did not recall the phrase “Twin towers are no more” I am sure they said it a lot but I cannot remember it being said at all. Also whenever I have read about it, its always been 9/11 or WTC attack, rather than Twin towers are no more. I think it might be said in the moment a lot, but when content came up to be written journos and writers must have come up with something different or more sober.
