It gets better.
That's the 27th, 28th, 29th, and 30th. Campaign ran for a day on the 27th, so the rest is illustrates the "fall off" ... however. I used a 'redirect' URL to track stats ONLY coming from The Hun (so, basically, that domain was registered ONLY in August, and ONLY used to track that). Over the next few months:
You see the HUGE dip in September, but then it picks right back up again in October, as bookmarkers come back, and the traffic comes in from the people who "scrape" the listings off of The Hun.
Then, I did an Autoblogger Pro campaign with another URL to track the differences "side by side":
Same fall-off patters, about 10% of the total traffic (although, free, instead of the cost of the Hun traffic). Then, over the next few months, I tracked traffic to a "target" site, to see how many would pop through the ABP campaign:
Overall, I found that conversions were decent for both methods, and The Hun sure does pour on the traffic.
I *just* capped these for you, so sorry for the delay in responding -- I was capping and uploading.
