Wonder why we don't have a forum for them.. Anyway I am new to linkshare and I can't for the life of me find out how often their reports are updated. I have been sitting at 853 impressions since last night. Do they do once a day reporting?
I'm having a similar problem. I show 4 sales but no commission. I've been with Linkshare for about 6 months now and I was only focusing on one advertiser. My sales were/are generated really through organic search and dumb luck of getting a great url. I can see that I get around 30 - 40 uniques per day and average a sale a week. It's not a huge payer, but I can tell you they do report. When exactly that sale was, in relation to date of posting is a different story.
