Be careful if contemplating writing for a website or any e-zines. Most are dodgy, never pay and present themselves unprofessionally (have low standards). "Website publications" are hopeless - in my opinion and in my experience. Most so called "website publications" are in fact blog-sites, in which everyone who writes-in, is "published". There is no glory or status in that. No payment either. "Website publications" often say they pay, but they don't. They keep you waiting forever. There's no kudos in being published on shonky websites. Until I hear of a successful website, run in a businesslike way, I recommend giving them a wide berth.
The world has moved on since I first gave that warning, and there are now plenty of serious online publications that pay properly and carry real standing. But the warning underneath it has not dated one bit, because the trap is the same as it ever was. It has just moved online. For every genuine outlet there are a hundred "content" sites that want your work for nothing and dress up the begging as an opportunity.
So judge the outlet, not the format. Here is how to tell a real one from a mill. A real publication has a named editor you can actually reach, a masthead of staff, and a clear rate it pays per piece or per word. It commissions work, sets deadlines, and treats you like a supplier it values. A mill, by contrast, offers you "exposure" instead of money, asks for endless free "samples", claims your words forever the moment you hit send, and goes quiet the instant you mention a fee.
Two questions cut through it every time. What do you pay, and when? If the answer is vague, or if the only currency on offer is exposure, walk away. Exposure has never paid a power bill. Spend your best work where there is a real editor and a real cheque at the end, and let the shonky sites find some other mug.
