Just spent a little while going through one network and found some interesting stats.

of all the entries these are the stats I came up with.

At present I have

Pending 29.5%
Accepted 39.9%
Declined 30.6%


So what of the reasons given for the declinedness of each item

Cancelled 23.2%
Invalid Payment 48.2%
Cancelled Fraud 10%
Finance declined 18.6%

These results are based on ppc visitors over the last 12 months
