What is cloaking? If it is possible good for seo?

How do you get your posts accepted by other bloggers while guest blogging?

I am trying to hire a freelancer for an app development of mine. And I am meeting many of them personally. But I don't know which one to decide in each case I have looked into their previous work but they have confused me by giving varying money options, working hours etc.

My conversions are low and I read in a forum discussion that using paypal may lower the conversion rate. So, I am looking for any alternative.

I am seeing a lot of content writers these days who basically doesn't have any value for their work. Recently I hired a content writer and got scammed. He just just changed some words and that's it. Apparently, it was way too much cheap too.
So, I feel lucky. Has anybody noticed them?
