If you are taking the time to create, publish and promote content to build backlinks, it’s smart to measure your progress.
Add website analytics to your website. You can spend cash on an analytics solution such as Adobe Web Analytics, but as a small business I would recommend using Google Analytics, which is free. Install the analytics tracking on every page of your website. You can check your analytics weekly, but once a month is just fine. Google Analytics will show you how an individual page is performing and which channels are driving traffic to that page (i.e. organic search, social media, web referrals etc.).
To track your website backlinks I suggest using Majestic, OpenSiteExplorer or Ahrefs. You will be able to get some data for free, but it is worth paying for these services if your goal is to build backlinks to your website.
This is not going to be an overnight project. You might not see dazzling results after six months. This is a marathon, so keep at this for at least 12 months and I promise you will see fantastic growth in backlinks and web traffic from organic search, social media and web referrals. Also, this is a form of backlink generation that will never be punished by the search engines like paying for links, or engaging in link farms.
Now go forth and broadcast your knowledge — and reap the benefits of your labor.
