I have a whole video series I’ve been meaning to finish up on this topic as it’s often overlooked in terms of what an “agency” actually is and what they can provide to you. You may have someone, who’s a moonlighting freelancer while in college and working part time at a pizza place claiming telling you he is an “agency”, while someone else who merely just resells some offshore white label solution claiming the same. There’s nothing wrong with either one of those two scenarios IF they provide results for you. You’d be surprised how many times the lone freelancer will out perform the big city agency with 100’s of employees, and it comes down to three things: time & commitment, experience, and costs. First, do they have the experience in your field of business? Have they ran ads for similar businesses before and doing so currently? If not, I’d look elsewhere as you don’t want someone who’s not experienced in that field to try and run your ads. There’s a lot of learning that has to take place, and you don’t want to sacrifice your performance and money while they learn. Second is time & commitment. How many clients do they currently have, and how many more are they looking to take on? A solo “agency” freelancer who’s working full time can probably handle four to seven accounts, assuming they are not small budget CPL models, I’m taking about actual digital media agency solutions. A larger agency typically will assign between five to ten clients per account manager. This is important because you want to make sure they’ll have the time to take care of your account and not chase the next customer. Lastly is costs. How much are they going to charge you? Compare that to the number of clients they have and that will give you a good understanding of their caliber of management, as well how much time they are going to devote to your account. If they are going to charge you $200/mo, then you’ll be lucky to get a couple hours per month at most; probably “set it and forget it” strategy will be used. Ask what you will get for what your paying, you want 30, 90 and 180 day timeline of goals setup. If they can’t do that, it’s a red flag they’re either reselling some junk service, or don’t have the time: walk away.
