I opened an online store selling home decoration items, and I tried out the whole craigslist advertising strategy. I pretty much put an ad on craigslist with the items i was selling and surprisingly enough within a few short minutes of posting, I would receive 5 or 6 visitors to that Item's web page. None of it ever converted into a sale, but its interesting and i wanted to learn more about ways of using that traffic "ethically" to get visitors to your info website.
another thing is that a lot of my ads were being taken down or flagged. Now i think i was following all the rules they had set out in the T & Cs, but i was still just hoping ads would stay up.
