This is a difficult question to answer because there is no formula to follow if you want to attract more traffic. HubPages attracts all sorts of writer, from the purely personal 'I've experienced this and want you to understand how I'm feeling and what I think' type of writing, to simple recipe writing. In between lies fiction,poetry and practical how to hubs.
In all genres the message is clear : if you want success, produce high quality informative hubs and keep them coming!! Statistics show that 80% of your traffic will eventually come from about 20% of your hubs, on average.
More traffic doesn't necessarily follow good writing!! Online writing varies tremendously in its quality but if you want to develop solid traffic and sustainable viewing then write about what you know in as passionate a way as you can. In time you'll create a core of readers and they'll organically pass on your content.
You can be yourself - as others have advised - and that's great advice - but be prepared to learn from analytics and other sources if you want increased traffic.
All the very best.
