Word of mouth is one of the best means of marketing a product, but sometimes the process needs a little help to get started. Help in the form of cold, hard cash. For a long time, the Pay-for-Posts business was considered only slightly less shady than buying watches from a guy who carries his stock in his coat.
A few years ago, I wrote a paid post for one of my blogs and Google promptly slapped me with a drop in my page rank (does anyone care about page rank anymore?) and placement in the search returns.
Now, paying for posts, Tweets, Facebook shoutouts or video mentions is not only acceptable, it’s good business.
