I see a lot of threads discuss pricing when it comes to ghostwriting. Many people (even I am guilty of this) give advice about upping your price point, when we're all forgetting one very important aspect - not everyone deserves more money.
Of course, it's very hard to tell if you have what it takes to deserve an increase yourself. Writers especially are very proud of their work (as they should be, especially if they've written from scratch) - and content to a writer is like a baby (that's why they call it "killing your darlings" when discussing editing - each word is valuable to you).
We're all doling out advice about asking for more, without really offering tips about whether or not they should be charging more.
Of course it stands to reason that you can charge whatever the hell you want - that's your right. But if the point is to build a thriving ghostwriter business and hang on to existing clients as well as bring new ones onboard, you have to build a reputation for quality and value.
Think of it this way: Say there's a guy with a big budget - money's no object for him. He would pay $30 per page for an article and feel like it was so well-written, he got it for a steal. And he could just as easily feel ripped off if he got a horrid article for just $5.
Don't necessarily think in terms of "price point."
Think of your charging abilities as a value equation.
How do you know you're worth more?
Feedback says a lot. If people rehire you, and tell you they're pleased, up your prices eventually - it means they liked what they saw and others will, too.
Do they refer their friends to you? If so, it means they trust you enough to put their reputation on the line.
Are you so busy you have to turn clients away? Up your price point a bit for new customers. Ease your way into the next tier of earnings so that you keep older clients with you and gain new ones willing to pay more.
Give yourself extra points if you conduct thorough research, write from scratch, and deliver on time - if so, you've already excelled far better than a HUGE percentage of other people calling themselves ghostwriters online.
