Marketing strategies should be target group of people- it could be short animation, or other visual attractive advertising ways. I am a digital marketing and content manager at this Povestiri erotice and I like it. Being a marketing expert, I like short animation as a advertising methods, but it should be customers oriented.
It neither good not bad - it's just another way of advertising that can work on not. There are many variables that can make such soucre of ads successful or not. I tried such ads in my project Tette nude - it showed a good performance for some period. I must say the animation itself is very important but it's very difficult to find something that will work . But if you manage to find such ads then you can scale it.
