Search Engine Statistics:
Estimated Database Sizes (2002)
1. This study was conducted in the 4th quarter of
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.coms study.
The estimate displayed above reflect only our own estimate.
6. AOL receives results from Google and was therefore
not included in this study.
