Get ready for more bells and whistles on e-commerce sites. More than nine out of 10 Web site operators plan to add Web 2.0 features within 12 months, according to Scene7's "Rich Internet Experience and Beyond" study, conducted in November and December 2007.

The leading additions planned for 2008 were alternative views (37%), user ratings and reviews (36%), video (35%), blogs (34%) and 360-degree spin (34%).

About four out of 10 respondents said they handled their own Web 2.0 development, while 13% said they outsourced it and about 46% said they did both.

Six out of 10 Web site operators surveyed measured the success of these enhancements by clicks and usage. About the same number did so by checking conversion rates. Nearly half said increased revenue was the main metric they used.

Other metrics used to determine how well Web 2.0 applications worked included reduced abandonment rates (35.5%), increased repeat purchases (29.6%) and higher average order size (28.4%).
