You still need to put some efforts into your link building strategy. Here is the rough step by step:
1. Know your product
Other people simply do not know what do they offer because they cannot explain what they sell, what they deal with and what its features, however you must know that. You must clearly understand who your customers are and why do they need you product. Start with that, figure it out for yourself, and then formulate it into words to explain this for other people as well.
2. Set objectives
This is worth it. Without that answer you won't succeed.
Before diving into the link building, you should gather as much information on the market as you can. The key to the success is information.
4. Build content

5. Keep working
Every day something happens and your website is better to reflect the changes, otherwise your competitors do that
