PPC Campaign Success

I think you're missing my actual strategy which is understandable because I did not volunteer it. My campaign differed from every other campaign I have done in one major way, in terms of the list.

Click -> Lander -> Choice

Once the user get's to the choice he or she can:
A) Sign-Up for the mailing list.
B) Proceed directly to the product.

So not everyone signed up for the mailing list. On top of that those who did not subscribe sometimes did not buy the product I was promoting (obviously). Now on the other hand some people did subscribe and out of those not all of them purchased.

So when I initially posted I said most campaigns were under 10% conversion; so your 19% is flawed; however, you thought that only my purchases came from subscribers and I can see the misunderstanding.
So in short I do not force people to sign up to my list to see the product that would be a waste of advertising dollars. I use something like this:

"Now you have a choice to make, you can provide your contact information in the box below, or you can be sent directly to xxxxxxx. Either way you will be on your way to success; However you will not have the backing of an established marketing company behind you. We will not send you affiliate offer after offer, we will send you solid industry proven advice at no charge! Keep in mind we got you to our page, right? We know how to get customers and again we will share this knowledge at no cost. You will never see this offer again, choose wisely."

As you can see the user gets a choice of which branch to take, I would never force a sign up to a list before the offer was given. Also the beauty part is when the user signs up to the list I dump them over to the affiliate offer as the thank you page. (Don't want to cool down a hot buyer)

So I had 925 keywords between 7 campaigns; I received 2,263 clicks and made 224 sales. So as you can see it is below 10% across all 7 campaigns; however I had two campaigns that were around 16% in terms of clicks to sales.

Out of the subscribers; 831 came from AdCenter and 337 from AdCenter; this number is slightly skewed because I did not have different forms for the two until I realized I needed to track this. So AdWords could have been higher, I won't know until next case study.

Hope this satisfies your query. If not please feel free to post any other questions you may have; I am more than happy to help the people (warrior collective) who helped me.

Edit:

And before you ask I received a great opt-in rate due to the awesome perks I was offering the reader. I would share these details but at this point I rather use them a bit longer myself.
