I recommend this online retail sales report by Coremetrics, which contains very interesting statistics on the most recent holiday season. For example:
- Between 4% and 5% of visits turned into orders on Black Friday and Cyber Monday during the 2011 holiday season.
- Over 5% of all visits were from a mobile device
Add Mobile Commerce to your ProductCart store - Average order value was around $190.
- Average shopping cart abandonment: around 65%
- Average conversion of new visitors: around 4%
- Traffic coming from social networking Web sites is still less than 1%.
Interesting data. Worth a read.
