Don't sacrifice morals for a quick buck — At the outset, you'll want to do all sorts of things to make money online, but don't sacrifice your morals for a quick buck. Not only will you put people off, but you'll lose Google's trust. You also shouldn't concern yourself with things like Adsense or other ads on a blog before you have around 100,000 visitors per day. Yes, per day.
Send relevant writing samples. If someone asks for an marketing writing sample, send them marketing writing samples. Don’t send a finance article. Or a fitness one. It’s hard for a hiring manager to know how well you understand the niche’s industry if they can’t see a relevant writing sample. Apply to opportunities suited to your skill set and experience. Also, if your pitch doesn’t have a list of links to writing samples, it’s going to get ignored.
