Search Engine Statistics: Estimated Database Sizes (2002)

NOTES

1. This study was conducted in the 4th quarter of 2002.

2. The results are our own findings and, although we consider them to be fairly accurate, they were not confirmed by the search engines and they should therefore not be regarded as official.

3. The estimated values are the average of the reported database size at the time, the estimated database size reported on SearchEngineShowdown.com and our own estimate based on the relative search engine database size reported in the previous graph.

4. Discrepancies between estimated values and reported values are due to many factors. Our study of relative database sizes was fairly small (30 search terms) and therefore cannot be regarded as 100% accurate. Search engine also typically spread their databases over several servers, any number of which may have been unreachable or down for maintenance at the time the study was conducted.

5. No reported database size for Teoma was available at the time of this study, nor would they give any specifics when asked. Teoma was also not included in SearchEngineShowdown.com’s study. The estimate displayed above reflect only our own estimate.

6. AOL receives results from Google and was therefore not included in this study.
