This is an interesting post John. As you point it the power of on line advertising is the level to which you can really target who have the opportunity to see it - you can test and tweak parameters and directly see the impact. Great job on delivering an important message.
Yes they do Peter! I strongly agree with that. Businesses should start investing in this manner of advertising. This is most especially to online firms. Positive and will planned advertisements will always make a good mark.
I have also experienced this kind of effect while looking a certain advertisement in my site at J Breaking News. By that, if I am part of the research, it really affects people!
