The Disadvantages of Viral Marketing

This is a very important reminder that viral marketing can be very damaging or even destroy a business. As well as viral marketing goes, the following disadvantages of viral marketing should also be considered before using this method to promote a business:
Negative Buzz
Sometimes, instead of creating a positive buzz about your business, viral marketing works in the opposite way. Human nature being what it is, people are more likely to talk about something they don't like with their friends, family members, and co-workers than to share something positive. The same techniques that can propel a business into online popularity and produce big traffic numbers can work in the opposite way.
If a few people start posting negative information about a particular venture on blogs and message boards, very few people will take the time to investigate for themselves to figure out whether this negative buzz is warranted. Instead, they will take what is being discussed as true and your business will suffer as a result.
Ethical Considerations
Many people have concerns about privacy issues. They want to know what the companies they do business with are planning on doing with their personal information and may not be interested in participating in a campaign if they think they are providing fodder for spam marketers.
Savvy Internet marketers make sure that they have a privacy policy on their web site that explains exactly how the information they collect will be used and they will not sell or rent their mailing list to other companies. This information should also be included in all e-mail correspondence the company sends out for marketing purposes.
Even with these policies in place, there will be some recipients who feel that viral marketing is a sleazy practice. They may even choose not to do business with companies that use it, and that defeats the purpose of viral marketing in the first place.
Hard to Measure
Any Internet marketing campaign must be measurable, so business owners and managers can determine whether it is effective. Viral marketing can be a hit and miss proposition, and unless the campaign is being handled by experienced individuals, it can be very difficult to determine whether it is a worthwhile proposition
