I have a mobile site that is 5 yr old ...some time back the work was stopped and now again started. No doubt, the traffic is rising but not equal to our efforts. Here is my site www.bestcontractmobilephonedeals.co.uk/ I hope i will get some response from you all.
Keep building quality backlinks to your website, expect it to take time because this is a very competitive niche that you're entering. If you can't do the work yourself, hire somebody who can.
you need to remember that backlinks are just one part of SEO you need to submit articles and do on page seo. if you do this you will see your traffic increasing. if you have any questions mate dont hesitate to ask.
