When you look at the pervasiveness of online advertising today, it is difficult to believe that the earliest form of the internet, ARPNET and NSFNet did not allow advertising. However, NSFNET began to loosen its advertising restrictions by 1991. Twenty years later, revenue from internet marketing in the United States totaled 31.74 billion dollars. By 2012, online advertising revenue reached 36.75 billion dollars, which was more than a 15 percent increase over the previous year.

Clearly, online advertising has quickly become a priority for all companies with any sort of hope for success and future relevancy. What this means is the most technologically savvy and innovative companies will lead their respective industries into the future. In doing so, they will focus on important internet trends like social media, social bookmarking tools, and the top link building sites; and they will find ways that their businesses can benefit from each of these tools.

Although the most innovative businesses will usually have the advantage, even if you do not know how to do link building there is still hope. Some will turn to link building wikis to not only educate themselves about link building, but to learn about the most effective link building practices. While link building guides can be helpful, they are not a must; because there are several affordable and effective link building firms who will help any business to achieve its goals.

One of the foremost advantages about partnering with link building companies is the fact that they are expert in many different aspects of online marketing. This means that the best online marketing companies can offer everything from social bookmarking services to link building. And many are affordable enough that you will never have to resort to social bookmarking or link building wikis for guidance.
