It's about time for me to pay back.
I've joined the digital advertising industry for a period of time, and I received a lot of help along the way. I am grateful to those who don't mind sharing with me, maybe just some ideas, time, or knowledge.
Anyway, I feel that it is important for me to start sharing something - about how to create/operate/evaluate/optimize a campaign. I guess the advertising industry could be a little better if people can understand more.
