I kinda disagree with Tariq. It is not true that using software will "backfire" which can result from Google banning the site and yours. First of, Google is quite strict but at the same time, they are careful. Not everyone who has a website knows the rules of Google so they take this into consideration. Also, there are several software out there that can help you with PR. I am currently using Brainboxvideo who does an awesome job in handling my website's needs. Also, the company offers a wide variety of features that will allow you to market your company without breaking any rules.
I agree with the above poster (mblevins17). Google is not the enemy. You just have to stay in the right direction by posting meaningful content. Besides, people know what spam is nowadays so it would hep your business grow if you post genuine, well researched content.
