WebTrends Inc. has launched WebPosition 4, which offers combined organic and paid search marketing analytics.

WebTrends says marketers can now easily view performance over time for specific keywords and their overall search marketing effort. This is done with the WebPosition 4's Keyword Visibility Index, a high-level metric that shows a site's overall visibility for all of its targeted keywords and search engines.

JupiterResearch estimates 87 percent of all commercial search engine referrals come from organic listings.

"As search engines continue to grow in importance, we are dedicated to truly changing the game for today's search professional and are proud to uniquely offer marketers the ability to achieve and maintain higher organic search positions which are so critical to their success," says Greg Drew, CEO and president, WebTrends, Inc.
