Very clever! People hate to miss out on things -- like the other half of the information, in this case.
I think you should never stick to one. The Op has given his tricks. We should look in the internet for more. It is all about trial and error. For the past few years, I was doing loads of SEO stuffs.

Working with many people, I now know that imagination and creativity is much important than hard work. Of course, some investment is also necessary.
