Traffic to Travel Sites Grows

Several travel categories gained in July as Americans left for summer vacations. The travel - ground/cruise category jumped 10 percent to 12.7 million visitors, making it the top-gaining category for the month, while the travel-information category grew 7 percent to 47.6 million visitors.

Some Retail Categories Gain Despite Economy

Despite a sluggish retail economy in the US, a handful of retail categories achieved traffic increases in July, possibly due to consumers' shopping online instead of using expensive gasoline to drive to the store.

Retail - consumer goods sites rose 8 percent to 22.5 million visitors, including double-digit growth by Staples.com Sites (up 22 percent to 6.5 million visitors), Office Depot (up 12 percent to 4.8 million visitors), and DisneyShopping.com (up 32 percent to 1.6 million visitors).

Meanwhile, the retail - mall category increased 7 percent to 28 million visitors, led by AOL Shopping with 6.3 million visitors (up 19 percent), MSN Shopping with 5.8 million visitors, and QVC Sites with 5 million visitors.

Summer Movies Drive Traffic to Ticket Sites

With the release of several highly anticipated summer films, most prominently The Dark Knight, retail - ticket sites grew 5 percent to more than 44 million visitors as movie goers pre-purchased tickets to avoid long lines and sell outs at theaters.

Moviefone led the category with 17.5 million visitors (up 12 percent), while Fandango posted a 29 percent gain to 9.3 million visitors, and MovieTickets.com jumped 13 percent to 4.7 million visitors.

Hot Celebrity Gossip Stories Prompt Growth

July was packed with major celebrity stories, including the birth of Angelina and Brad's twins and Christie Brinkley's public divorce, which helped boost the entertainment news category 5 percent to 52.7 million visitors.

Gossip site omg! led the category with more than 16 million visitors, a 19 percent gain from June, followed by TMZ with 9.7 million visitors (up 9 percent) and People with 8.8 million visitors (up 4 percent).
