There's a lot of amateurs blundering around in this area, but only TRUE pros are following my three-point plan to making GREAT adverts:
1. Find something wonderous or at least humerous on YouTube.
2. Steal it.
3. Make it original again by replicating the first thing BUT adding a brand message to the end.
At the moment these are LITERALLY the keys to the kingdom. Ignore them at your mild peril.
