The leading sites in three key Web categories – search, career development and multi-category travel – experienced high month-over-month visitor retention rates from June to July, but also significant audience overlap with the other top players in their categories, according to Nielsen/NetRatings.
Search Sites
Among those categories, search providers had the highest visitor retention rates, with an average of 71% of June visitors at home returning in July among the three leading search players, NetRatings reported (pdf):
- Google Search led with a home retention rate of 79%
- Yahoo Search followed with 69% retention.
- MSN/Windows Live Search audience retention was 65%.
Visitor retention rates were slightly higher among the work audience, with an average of 76% among the three leading search providers.

- MSN/Windows Live Search had the highest audience overlap, with 84% of its unique visitors also going to Google Search, Yahoo Search, or both.
- Yahoo Search had a 78% audience overlap with Google and/or MSN.
- Google Search had a 63% audience overlap with one or both of its two primary competitors.
