A very popular mistake that is made by most new marketers is trying to force people to participate in their viral marketing and advertising campaign. You need to accept that viral marketing and advertising works through simple word of mouth: people share your tricks and products simply because they like them and want other people to benefit from them as well. Now when you try to force it on them, then it is obviously going to backfire. Instead of wasting energy on that kind of thing, focus your energy on making your viral marketing campaign as great as it can maybe be. Work tricky so that your subject matter is so well done people won't be able to stop themselves from promoting it to their friends. If you feel like it is tricky to get people to take part in your campaign, there is probably something wrong with it. The best way to test it out is to ask yourself, "Will I tell my friends about this?", if you get a non biased "yes" as an answer, then you are in luck. Do whatever you can to make the campaign spread on its own, rather than any compelling force.
Make sure you're tracking and analyzing the results of your viral marketing campaign. How come? You do this because you want to know ways to better your campaign and get better returns from it. If you do not track your campaigns results you won't know how to make it better and get better results. When you are monitoring your campaign, you should see that the conversion rates are high when compared to the click through rate. You should be able to increase your click-throughs and at the same time be able to convert the search engine traffic into conversions/leads.
To ensure the success of your campaign, do a couple of research before you start building. Viral marketing and advertising works in much the same way: discover everything you can before you build a campaign. Besides that, if you don't know enough about your target audience you won't be able to sell to them. This is why it's very imperative that you compile enough research data on your audience before you start a campaign. More here Halloween ideas.
