The first thing I noticed was the grammar mistakes. For example, the title of your latest blog, "How Does a Sofa Recliners Work?", is grammatically incorrect. Plus, there were some other grammar issues in the post itself.
To see the results you want, you're going to have to be considered an expert in your niche, and you can't establish yourself as an expert if you have errors in your content. If grammar isn't your thing - and, trust me, alot of people fall into that category!
-, outsource your writing, or, at the very least, hire someone to edit/proofread your work.
Plus, as someone else said, the content didn't really wow me. It was very long, without alot of substance. Your content should be compelling and encourage readers to come back. If people are bored by your content, they won't hesitate to hit the 'back' button. And, again, it's no knock on you. There are plenty of people out there who hate to write or aren't very good at it, even if they know everything there is to know about their niche.
Once you get those issues settled, you could try some guest blogging to get more traffic. A quick Google search can help you find blogs that accept guest content. Just make sure that the blog you choose is relevant to your niche, and that the content you publish offers readers there a reason to visit your site.
