James Lamberti, Vice President of Search Solutions at comscore Networks, presented today at the Search Engine Strategies conference in New York. comScore gathers its data from 1.5 million users and Lamberti provided some interesting statistics on search behavior.
- Toolbar searches in the United States have grown 136% since June 2004.
- 18% of searches come from toolbars.
- 58% of searchers have not installed toolbars.
- 12% of searchers have uninstalled the toolbar.
20% of the search users constitute 68% of the search volume. These users are less likely to click a sponsored link (27%).
The search race is closer than I thought. comScore measured the work search market share as 37% Google, 30% Yahoo!, and 19% MSN based on total searches.
