A friend of mine used to keep a post-it note on her monitor with 2,073,418,204 written on it. She was keeping track of the number of pages google reported it had indexed[1]. We got very excited when it changed to 3,083,324,652.

- tgb 14y agoDoes Google report this anywhere nowadays? I searched for it a while back and couldn't find it.
- sovok 14y agoI found only estimates: http://www.worldwidewebsize.com/ http://www.worldwidewebsize.com/ 40-50 billion pages. From the site: "The size of the index of a search engine is estimated on the basis of a method that combines word frequencies obtained in a large offline text collection (corpus), and search counts returned by the engines. Each day 50 words are sent to all four search engines. The number of webpages found for these words are recorded; with their relative frequencies in the background corpus, multiple extrapolated estimations are made of the size of the engine's index, which are subsequently averaged. The 50 words have been selected evenly across logarithmic frequency intervals (see Zipf's Law). The background corpus contains more than 1 million webpages from DMOZ, and can be considered a representative sample of the World Wide Web."
- user24 14y agoI'm wondering if they removed it because the definition of a 'page/document' changed to the point where it's no longer a meaningful number. I'm talking about realtime search etc. A shift towards viewing data as being delineated by the information it contains instead of the documents that contain it.
