Woman to Woman, Online

Sites aimed primarily at women, from "mommy blogs" to makeup and fashion sites, grew 35 percent last year — faster than every other category on the Web except politics, according to comScore, an Internet traffic measurement company. Women's sites had 84 million visitors in July, 27 percent more than the same month last year, comScore said. Advertisers are following the crowd, serving up 4.4 billion display ads on women's Web sites in May, comScore said. That is more than for sites aimed at children, teenagers or families. "Moms are the decision makers of the household as far as purchases are concerned," said Chris Actis, vice president and digital director at the ad agency MediaVest. The rapid growth in advertising and traffic to women's sites has attracted the attention of major media companies and venture capitalists.
