Caleb offers some good advice to check your facts, using a recent Guns.com mistake as an example. I haven’t found commercial blogs to be any more thorough in terms of getting facts right than amateur bloggers. If anything, because amateur bloggers link more readily within the community, error is more likely to get pointed out by someone who has the correct facts, noticed and corrected. If your goal is to make money, Google won’t ding you for bad facts or rumor mongering. It may even be beneficial.
