Don’t be blindsided by what you don’t know. That is especially true if everybody else knows it. 
Internet marketing is largely about selling yourself. If you can do that then you can sell your products. If you can’t do that your products will probably collect dust until you finally decide to throw them in the dumpster.
Selling yourself in an information society means that you need the information. It’s like a lawyer trying to make a case in court. The one thing that is a definite killer is being blindsided by the advocate for the other side using something that you did not know. If what you did not know is also public domain and common knowledge, then instead of selling yourself as an expert, you have sold yourself as an idiot.
So how does this relate to internet marketing? It’s simple. You have to do the work to maintain your expertise in your niche market, whatever that is. That means putting in the hours to keep up, and that means reading the blogs and articles and new media coverage of your market place – every week – every day – preferably on a schedule that you never miss. In other words, you actually need to become the person that you sell.
Without the work that you put into developing yourself you will be relying on magic to provide you with the something for nothing that we all dream about. It happens, sometimes, but don’t hold your breath.
Here is what I recommend as a daily schedule.
1. If your market changes rapidly spend 2 to 4 hours reading everything you can find on your niche market. In a slow moving market spend at least an hour verifying that nothing new has emerged. Comment on the blogs of others and email and send comments to byline journalists who write articles in your field.
2. Spend about an hour composing every new thing into a blog, and then publish it. If nothing has changed then blog about the stability and reliability of the market and provide some refresher remarks about interesting aspects of the market.
3. Market your blog on all the appropriate networks, Myspace, Facebook, Twitter, etc.
4. Relax for awhile, then respond to comments and emails that your marketing may have manifested.
5. Now go do your regular day job – eat healthy – get some sleep – and then do it all over again.
