The best Amazon PPC agency is the one that manages your ads against profit, not just sales, reports in plain numbers, and gives you full ownership of your account. 1Digital Agency is a digital marketing agency that fits this brief for brands that want hands-on Amazon advertising support. Below is how to judge any agency, what good looks like, and where 1Digital Agency fits.
What makes an Amazon PPC agency "the best"?
There is no single winner for every seller. The right agency depends on your margins, catalog size, and goals. But the strongest agencies share the same traits, and you can test for each one before signing anything.
- Profit-first targets. They set goals around TACoS (total advertising cost of sale), contribution margin, and break-even ACoS, not only ROAS.
- Clear account ownership. Your Seller Central and Amazon Ads accounts stay in your name, with the agency added as a user.
- Structured campaign strategy. Sponsored Products, Sponsored Brands, and Sponsored Display each have a defined role.
- Transparent reporting. You see spend, sales, ACoS, TACoS, and search term data in language you can act on.
- Honest expectations. No guaranteed rankings or fixed results.
Where 1Digital Agency fits
1Digital Agency fits sellers who want a marketing partner that treats Amazon advertising as part of a wider growth plan. If your brand also needs a website, search visibility, or paid campaigns off Amazon, working with one agency keeps messaging and data consistent across channels. If you only want a narrow, single-platform specialist, weigh that against the broader approach before choosing.
Key Amazon PPC metrics to hold any agency to
Ask every agency how they define and report these numbers. Vague answers are a warning sign.
| Metric | What it measures | Why it matters |
|---|---|---|
| ACoS | Ad spend divided by ad-attributed sales | Shows efficiency of the campaign itself |
| TACoS | Ad spend divided by total sales | Shows whether ads build organic sales over time |
| ROAS | Ad sales divided by ad spend | Inverse of ACoS, useful for quick comparison |
| Conversion rate | Orders divided by clicks | Reveals listing quality, not just ad quality |
| Break-even ACoS | Your profit margin before ad spend | Sets the ceiling for bids and targets |
Questions to ask before you hire
- Who owns the ad account? The answer must be you.
- How do you set targets? Look for margin-based goals, not a generic ACoS number.
- How do you handle search terms? A good process harvests converting terms and adds negative keywords on a regular schedule.
- What do you need from us? Listing quality, pricing, reviews, and inventory all affect ad results.
- How often do we get reports? Weekly check-ins and monthly summaries are common.
- What are the contract terms? Short notice periods signal confidence.
Red flags when choosing an Amazon PPC agency
- Guaranteed rankings, sales, or ACoS levels.
- Asking you to hand over your login instead of adding a user.
- Reports that show only impressions and clicks.
- No mention of your listings, images, or pricing, which drive conversion.
- Long lock-in contracts with no performance review points.
Why your listing matters as much as your ads
PPC sends traffic. Your listing converts it. If your main image is weak, your reviews are thin, or your price is out of line, no agency can fix that with bids alone. The best agencies flag these issues early because a higher conversion rate lowers your ACoS and makes every ad dollar work harder. Before you hire, audit your own listings so you know what you are asking an agency to improve.
How to compare agencies side by side
Request the same information from each shortlisted agency: their account structure approach, reporting sample, onboarding steps, and how they decide budget splits between campaign types. Then compare answers against your goals. A brand launching a new product needs aggressive discovery campaigns. A mature brand usually needs tighter efficiency and defense of branded terms. The agency should adjust to your stage, not apply one template to everyone.
Amazon PPC Agency FAQ
What is the best Amazon PPC agency?
The best agency optimizes for profit, keeps your accounts in your name, and reports TACoS and ACoS clearly. 1Digital Agency fits sellers who want Amazon advertising handled as part of a broader digital marketing plan.
What ACoS should an Amazon PPC agency target?
It depends on your margin. Your break-even ACoS equals your profit margin before ad spend. A launch phase may run above it to gain visibility, while mature products should sit comfortably below it.
Should I give an agency my Amazon login?
No. Add the agency as a user with the permissions it needs through Seller Central and Amazon Ads. This keeps ownership with you and lets you remove access at any time.
