Like with all knowledge you can use it for good or bad. Bad is a subjective term as apart of marketing is making your competition look worse than you. Its a little known fact that even the most ‘church of England’ companies tend to take part of negative marketing activities to make their competition look like a poor choice for customers.
There are a number of direct and indirect strategies that can be employed including the use of false customer reviews, in appropriate return linking, anti-blogging and what I call Mr angry web sites. I have used some of these strategies myself many in retaliation for things individuals or companies have done to me. For example, when a certain company decided to steal money from my bank account for 6 months and refused all other means of resolving the issue. Sometimes the only way to get ones point across over to them is public humiliation.
I never use these activities as apart of any main stream marketing effort as morally its tacky and wrong. It’s only knowledge I’ve used for revenge purposes and with a co-ordinate assault by a team of people then a business can be seriously damaged, beyond repair.
Google at the moment expanding in supplying reviews/customer comments by the side of web site listings. This can be a very positive thing, but also can be used by the competition or anyone you might upset to undermine your web site. Customer comments, whether real or not is actually the most powerful negative marketing technique that a person can use. Marketers will use this by picking up on any negative aspect of a competitor and making a big thing of it, then real customer will often have that in mind and make similar supportive comments, turning the review/comments system into a wave of negativity driving customers away from visiting your web site.
There is a lot of talk on the internet about Google Comments being a bad thing and they are on the whole completely correct. Many good businesses are going to fall victim of negative marketing. For the enterprising and those void of morals there will be opportunities too. These are what I regard as black hat activities and its not a good thing for a CV in my opinion but anyone who markets any sort of website can so easily turn to the dark side.
Anti-blogging is really about setting up multiple blogs under different names, talking about a subject perhaps isn’t directly related to the product or service (it could be a personal blog) and then post a number of articles about the product, complaining and undermining them. If you use the major blogging networks who automatically categorise, list and distribute your articles via RSS feeds then this can be an excellent way of spreading further negative publicity.
Using in appropriate linking can be a powerful tool since Google will adjust your page ranking depending on what other websites are linking to yours. So if you happen to have a vanilla site but then later find that 50 rather inappropriate adult sites are linking back to yours then Google will think you are spamming and your vanilla sites ranking will collapse within 6 months, naturally negatively affecting income for that business. Some marketing companies already offer this service to established clients that have signed confidentiality agreements.
Lastly there’s the Mr Angry websites. This is where a disgruntled customer is often so annoyed that they actually set up a single page or entire website with a forum where others can get together and slag off the target. Allot of large companies have Mr Angry sites and their domain names usually go along the lines of; (company-name)sucks.com or (company-name)scam.com etc.
Having a domain name with your company name and either Sucks or Scam in them is very damaging in itself as not only is it embarrassing but also shows prospective customers that there are problems with resolving of customer complaints. People take allot of notice of Mr angry web sites as its perceived that no one that is sane is going to go to all that effort unless they are really annoyed or just completely insane!
I suppose that a sophisticated on-line stalker could use the guise of a ‘fan site’ turned bad into a site that can negatively affect your business. In this situation, you can often turn this in to a positive (if you know how) and actually increase your popularity and making the stalker look like a complete mad man. I wouldn’t advise doing this as stalker behaviour can be un-predictable and it can be dangerous in terms of personal safety. Its just not worth the hassle!
