Google Sites was the most popular property in Turkey in September with
18.4 million visitors, reaching 93.0 percent of the total online population,
followed by Microsoft Sites with 17.6 million visitors. Social networking
giant, Facebook.com, ranked third with 16.1 million visitors, having grown 26
percent in just the past six months. Dogan Online, which attracted 11.1
million visitors in September, led a total of seven Turkish-based properties
that ranked amongst the top 15, including Milliyet Group (8.8 million
visitors), Mynet A.S. (8.3 million visitors) and Blogcu.com (8.2 million

"The Internet audience in Turkey is one of the most active and engaged
audiences in the world," said Jack Flanagan, EVP of comScore World Metrix.
"Internet users spend on average more than one hour a day online, ranking it
among the five most engaged online populations worldwide. Although global
Internet brands like Google, Microsoft and Facebook are among the most
visited in Turkey, there is also a vibrant community of home-grown Web
properties like Dogan Online and Milliyet Group. Turkey is clearly a market
with exciting potential."
