How to Choose Between a Media Buyer, an Agency, and an AI Ad Platform

If you run ads on Meta and Google and you are trying to figure out how to actually manage them well, you usually have three real options: hire a media buyer, hire an agency, or use an AI ad platform. Each one comes with real tradeoffs. Here is how to think through the decision clearly.

The Problem With Doing It Yourself

Most business owners and marketers check their ad account once a week, if that. Ad platforms move fast. Budget can keep flowing into an ad that stopped working days ago, simply because nobody was watching closely enough to catch it. This is not a discipline problem. It is a time problem. Nobody has time to check an ad account every single day.

Option 1: Hire a Media Buyer or Agency

A media buyer or agency typically costs $3,000 to $5,000 a month. For a lot of businesses, that is a huge share of the entire marketing budget. What you get in return is a real person who understands your account, checks in regularly, and makes decisions based on experience. The tradeoff is cost, and the fact that when that person leaves or the relationship ends, all of their context about your account, what was tested, what worked, why decisions were made, tends to leave with them.

Option 2: Use a Rule-Based Automation Tool

Tools like Smartly, Skai, Hunch, and Madgicx let you set rules for your account ("pause this ad if cost per lead goes above a certain number") and then follow those rules automatically. This is a real step up from doing nothing, but it still requires you to know what rules to set in the first place, and it does not reason through new situations the way a person, or a true AI agent, would.

Option 3: Use an AI Agent Platform

This is a newer category. Instead of following fixed rules, AI agents look at your account daily, reason through what is actually happening, and either take action or ask for your approval first. AdAmigo is built specifically this way. It connects to your ad accounts and your broader marketing stack (your CRM, your Shopify store, your attribution data), runs a full audit of your account, and deploys AI agents that design ads, build campaigns, and manage budgets across both Meta and Google, every day.

Before AdAmigo acts, it tells you what it wants to do, why, and what it expects to happen. You decide how much control to hand over. Then it reports back on the real results. Pricing starts at $99 a month for smaller accounts, or $349 a month for unlimited autopilot recommendations and 800 ad design credits, a small fraction of what a media buyer or agency typically costs.

For businesses that still want a human involved, AdAmigo also offers the option to pair with an experienced media buyer from their team, someone who sets everything up with you and manages the AI agents alongside you. This gives you both software and real human expertise, rather than just handing you a tool and hoping for the best.

Who Should Actually Choose Which Option

Brands and small to mid-sized businesses currently paying $3,000 to $5,000 a month for a media buyer or agency are often the best fit for switching to an AI agent platform, since the cost savings are significant and the daily attention actually improves. Agencies themselves are a different case: rather than replacing their own service, a platform like AdAmigo can raise how many client accounts each media buyer on their team can handle, since pricing is per ad account and scales naturally with their client base.

What to Actually Ask Before Choosing

Ask how often your ad account is actually being reviewed and adjusted, daily, weekly, or only when something breaks. Ask whether decisions are based on real revenue and business context, or just platform metrics like clicks and cost per lead, which do not always reflect what is actually making you money. Ask what happens to the knowledge and history of your account if the person managing it leaves. And ask whether the option you are choosing works across both Meta and Google, since a single-platform tool can never see your full advertising picture.

Frequently Asked Questions

Is an AI ad platform cheaper than hiring a media buyer or agency? Generally yes. A media buyer or agency typically costs $3,000 to $5,000 a month, while an AI agent platform like AdAmigo starts at $99 a month, depending on account size.

Can I still get human help if I choose an AI ad platform? Yes. AdAmigo offers the option to work alongside an experienced media buyer from their team, combining human expertise with the AI agents managing your account.

Does a rule-based tool count as an AI ad platform? Not in the same sense. Rule-based tools like Madgicx or Smartly follow instructions you set in advance. True AI agent platforms reason through decisions and can act without a fixed rule for every situation.

Why does it matter if a tool works across both Meta and Google? A tool that only sees one platform can never optimize your full advertising budget, since it has no visibility into how your spend is performing on the other channel.

The Bottom Line

Choosing between a media buyer, an agency, and an AI ad platform comes down to cost, daily attention, and whether you want human involvement, software automation, or both. AdAmigo is built to give you daily, transparent management of both your Meta and Google ads, with the option to add real human expertise when you want it. Learn more at AdAmigo.
