One of the parameters used when trying to gauge how successful a symposium has been is that of attendance: where the relevant question is the one as to how well attended the symposium is. And if a symposium is to be well attended, it needs to be well publicized. In fact, one of the things that can go wrong is to end up with a symposium that is poorly attended, due to lack of publicity. And as it turns out, one of the mediums you can use to create the necessary publicity is the Internet. There are actually two ways in which you can go about publicizing the symposium through the Internet.
One approach you can use while trying to publicize an upcoming symposium through the Internet is that of advertising the event online. You can opt to use the pay per click approach to online advertising. You can also opt to use the pay per impression approach to advertising. The most important thing is to identify the websites that are regularly visited by the people you are targeting as symposium attendees, and then ensure that the ads run on such websites. Of course, online advertising can be expensive. While trying to book advertising space online, you will be competing against real estate companies, credit card financiers, entertainment companies and others that are able to spend huge sums of money on advertising. But you can still get a decent return on investment, by coming up with a well targeted online advertising campaign.
The other approach you can use while trying to publicize an upcoming symposium through the Internet is that of targeted endorsements and placements. This will entail requesting people who write online to mention the event in their writings. You may find, for instance, that there are certain websites that are regularly visited by the people you are targeting as symposium attendees. You can then request the people who write the articles that appear on such websites to mention the symposium in their writings, in order to create publicity for the symposium.
