Hello, I am an advertiser, I want to have several individuals be able to login to my adwords account and setup ads, but I do not want them to be able to sabotage my account and possibly delete campaigns of others, etc. How can I limit their actions and what is the best way to do this? Please help!
There is no way to prevent this. You have to trust the person or persons you allow to have access to your account. The vast majority of managers will not do anything to sabotage anything. I don't know why you want several individuals, maybe your have so many campaigns that one person cannot do it all. I would suggest however only one person, not many. Also, it is best to give them your account ID and let them link to their MCC account. They have less access although not to the level you suggest. Unfortunately, only one manager is allowed such access per account so this wouldn't work for many people.
I second on Lucid's advice. The risk may be bigger if you have to have many people to manage your ads and get access onto your Adwords account. I would suggest you focus on the campaign that you receive results the most and have it utilized by one staff. That way, you'll not worry to not trust at all since you've tested that campaign ever since and it has always worked.
