There are plenty of sources for free advertising. I used ads, and got 1 view out of it. I stopped for one simple reason. "Impressions". When I looked at things to buy for myself, I noticed the featured items in the ads space. I did not like them, but continued shopping. Those same items were at the top of every page I looked at... and I felt bad because I knew they were getting tons of "impressions" from me-one person flipping through pages that had no interest in the ads. So it seems like "false impressions" to me. I'm fairly sure that's how it worked, but if not, I stll didn't find much traffic from ads. If you have good keywords, and SEQ and whatnot, you will be found. Free advertising is adressed in other teams. Its work, but you get more real views and interested views vs forced views.
