Hi Guys, Recently I tried to test clickbank + Bing ads method and see if ppc is really profitable. I opened two accounts, added 50$ in 1st and 100$ in 2nd. I chose a good product with about 120 gravity and with affiliate tool page. I had an old domain (something relating to deals and offers) lying idle, so thought of using it for testing before buying domains for each product. I pointed my domain to the landing page provided by that product. So my home page had that product landing page. There after, I set up an ad (on 50$ a/c), added lot of kws but removed some with high click rate as I did not want my account to be consumed soon but get lot of clicks. I started monitoring the clicks then which started coming after sometime. I was really surprised to see my first sale (45$) in 23 clicks! The next also happened at night in about 60 clicks! so I had made 2 sales and still had about 25$ left in my a/c. I was thinking the ROI was pretty good since I was doing this first time. Then I thought of increasing the products and using my 100$ a/c. Since I had just 1 domain available, i thot of using subdomains like www(dot)(productname)(dot)(my main domain).com ( www.xxx.yyy.com). I created such 3-4 subdomains and added ads for similar 3-4 products. Thereafter, though I am getting clicks, but no sales. Now I have used up almost 150$ in ads but made only about 90$ thru those first 2 sales. Please help me understand, where I went wrong, what was I doing right and how could I set a better compaign. Any suggestions would be appreciated.
