Members have written here before about stats suddenly going blank at particular perods during the day and no leads/sales being recorded. Well, I found that from my advertiser that this is due to batch processing by advertisers that causes publishers to lose money. After the batch processing is done, all transactions that failed to show up until then due to the normal delay that CJ has, is never recorded again. This means that say the batch processing is done at 6 AM and your stats are yet to show the transactions that have taken place between 2 AM and 6 AM, you can forget about ever seeing them after the batch procesing is done. The batch processing generally happens in US time at night. You can see this pattern by noting when the difference between clicks and leads/sales is the highest. Thats when the batch processing has been done and your stats are not showing the leads/sales and you have lost revenues. At other times of the day, there generally is little difference between clicks and leads/sales.
