Statistics for Traffic Referred by Search Engines and Navigation Directories to Useit

by Jakob Nielsen (April 11, 2004)

The following table shows the number of visits that have been recorded in the Useit server logs as coming from search engines and directory services (so-called "portals") in a one-month period (March) in each of the years from 1998 through 2004. The true number of visits is slightly larger since some browsers don't report accurate referrer URLs. Also note that the number of users is likely to be smaller than the number of visits since people sometimes use multiple search engines or repeat a search.

Portals and search engines accounted for about half of the "unique visitors" to Useit. In comparison, the HypertextNow site gets 30-40% of its visitors from portals and search engines.

Overall search-engine-driven traffic increased by 9% during the last year. This was much slower growth than the 95% recorded from 2001 to 2002. The extreme growth in 2001 was likely due to the emergence of Google as the dominant search engine, since Google has a tendency to drive traffic to high-quality websites.

The slower growth since 2002 is realistic for the more stable Web we are seeing now that Internet use is close to saturation in English-speaking countries. Even though Useit has an international outlook, it is written in English and thus attracts the majority of its traffic from the U.S., Canada, the U.K., and Australia. Other countries still have rapid growth in Internet use, but people are unlikely to find an English-language site through search engines if they enter query terms in other languages.

Traffic to a site from a search engine depends on three factors:

The most interesting observations from the table are:

The type of statistics shown in this table may be seen as a leading indicator for the future of portal companies: their ability to guide users to high-quality content is likely to influence their future use since people will tend to stay with services that give them good results and will tend to recommend the good services to their friends. Services that do not succeed in guiding users to good pages may suffer a drop in usage over the long term since people will change service when they discover a better one.
