Below about $1,000 a month in ad spend, run it yourself with a tool. Between that and the point where a percentage point of efficiency matters daily, a freelancer is usually enough. Above it, or when advertising has to coordinate with creative and inventory, use an agency.
The short version
- Spend level sets the shortlist. There is no hard minimum, but around $1,000 a month is where optimization has enough data to be meaningful.
- Ask who does the work and where they sit. Advertising is the discipline most often quietly subcontracted.
- Tools execute, people decide. Automation is very good at bids and very bad at knowing when to stop.
- Watch the fee structure. A fee that rises with your budget rewards spending, not efficiency.
- Advertising cannot be judged alone. Its results depend on price, images, rating, and stock position.
The number that sets your options
Start with monthly ad spend, because it determines how much signal exists to optimize against. There is no hard floor to advertise at all, but below about $1,000 a month the data is thin enough that most changes are noise. Paying anyone a meaningful fee to optimize noise is poor value, and a tool plus two hours of your own attention a week will do the job.
Once spend is consistent and the account has a stable set of converting search terms, the calculation changes. At that point a percentage point of efficiency is worth real money every month, and buying skill starts to pay for itself. Above that again, the constraint stops being campaign structure and becomes coordination: advertising decisions that ignore stock levels, price changes, and creative refreshes will undo themselves.
The three options compared
| Tool | Freelancer | Agency | |
|---|---|---|---|
| What it actually does | Automates bids, harvesting, dayparting, reporting | Builds and manages campaigns with judgment | Manages advertising inside the whole account |
| Cost shape | Subscription, often tiered by spend | Monthly fee or hourly | Monthly fee, sometimes a share of spend |
| Coordination with creative | None | Rarely | Expected |
| Cover during absence | Continuous | None | Yes, if the team is staffed properly |
| Main risk | Optimizing towards the wrong target | Single point of failure | Paying for breadth you do not need |
When a tool is the right answer
If your listings convert, your catalog is small, and your spend is modest, software is the highest return option available. It will harvest search terms, apply negatives, adjust bids on a schedule, and produce reporting you would otherwise build by hand. What it will not do is tell you that a product's advertising is working perfectly on a product that should be discontinued.
When a freelancer is the right answer
A specialist is a good fit when the gap is bounded. You have the listings handled, you have someone watching inventory, and you need campaign work done properly by someone who does it every day. The risk is concentration. One person means no cover, and the handover when they leave is only as good as their documentation.
When an agency is the right answer
When advertising has to be coordinated with everything else. If the same team owns the images, the copy, the price, and the campaigns, the decisions stop contradicting each other. That is the argument for a managed team, and it is the only argument. If you are buying an agency purely for campaign management on one product, you are overpaying for coordination you do not need.
The question that separates candidates
Ask who does the work and where they sit. Advertising management is the easiest service to resell, and a proportion of it moves through subcontractors the client never meets. Our answer is that all of it is in house, including the team that builds our own advertising and marketing tools, with no subcontracting at all. Yours may be different, but you should know the answer before you sign rather than discover it from an email signature six weeks in.
The follow-up questions are worth asking in the same breath:
- Which specific person will touch my campaigns, and how many accounts do they manage?
- Do you use your own tooling, a licensed platform, or manual management, and why?
- If my advertising cost of sale improved by turning campaigns off, would your reporting show that as a win?
- What is the fee if my ad budget doubles?
What most agencies will not tell you
Advertising results are the easiest thing in this business to present flatteringly. Turn off the campaigns that convert least, and efficiency improves while total profit falls. Report on branded search terms, and the numbers look excellent while telling you nothing about new customers. None of that requires dishonesty, only a choice about which chart to show first. Insist on contribution profit alongside the advertising metric and the problem disappears.
The second point is about fee structures. A fee expressed as a share of ad spend means the person advising you on your budget is paid more when it rises. We charge a flat monthly fee starting at $800 with no commission and no revenue share below $50,000 a month in profit, precisely so that recommending less spend costs us nothing.
