I will be completely honest with you – I'm not expert at finding customers late in the purchase lifecycle. Keywords vary based on niche, and I don't have any rules except for gut feelings. I'm sorry that I can't explain it better. But if you keep this in mind while doing your keyword research and writing your posts, you're heading in the right direction.
Slave away indeed. I’ve spend countless hours writing and doing various other website things. Really, I could never count the hours. Probably averaging 3 hours per day over 1.5 years is almost 2,000 hours of work, probably more. But as you said, it’s cumulative, so eventually you can kind of kick back. Of course, by then, once you get the hang of things, you’ll see previous mistakes you made, and have a million ideas for other projects, so it’s not likely that you will actually slow down! The great thing about online business is that your income is only limited by how hard or how smart you work. You are in control.
Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. There is also "fake traffic", which is bot traffic generated by a third party. This type of traffic can damage a website's reputation, its visibility on Google, and overall domain authority.
