I am on the fence when it comes to back links I don't feel they are important because your not selling on a backlink, your competitors or relevant sites are going to tell you to go pound sand lol they do not want to link to a website lower on the rank pole plus they do not want you taking their customers. so far the best way I have found for getting traffic is advertising. Facebook being the most cost effective so far. Go where your customers are. build your brand just use good SEO practices & the rest will fall inline. One really important lesson I have learned do I want to be in the web development business or the eCommerce business. I would prefer the eCommerce business.You should be focused on Marketing & sales not back links. That is just me I guess I think sometimes we loose perspective of what is really important. I want to have a successfully eCommerce store. Would I perfect 50 Sales a day or 50 back links well I will take the sales. The back links are not going to help me stay around in the next year but the sales will.
