I have built my facebook page as owned by a self-employed Professionnal Photographer which turned out to become the biggest in the world.
On a one by one based personnal user experience.
Answering every fan.
Never baught a single vote.
Never asked for likes.
Never did any specific campaign nor travel accross the globe « like campaign ».
They simply love what I do and I do my share by talking about them as well, when and if I have time.
