Handling the advertisement for two competitor companies can be very risky for the agency. If the secret information gets out then the client of the company would be disappointed and he would lose trust on the agency. Like I mentioned previously adding value is not the only important thing that allows your company to succeed but also adding trust. If the client doesn't trust you with their brand and company then they are not going to hire you to do their advertisement. Imagine if no one would trust your company?

Your consumers are your #1 fans thus you want to conquer them. Therefore having a good promotion is very important for a brand. This is why companies spend so much money on advertisements.
