If you’re selling on Amazon and relying on “set and forget” listings… you’re already losing.

Amazon is not eBay. It’s not Shopify. It’s not Google.

It’s a search engine with a checkout button.

And if you want rankings, reviews, velocity, and real margin — you need an Amazon SEO agency that understands how the algorithm actually works.

I’m Tommy McDonald from SerpLogic. We’ve ranked in some of the most competitive niches online (casino, crypto, finance). Amazon is no different. The fundamentals are simple:

Visibility → Clicks → Conversion → Velocity → Rank → Repeat.

The problem? Most agencies don’t understand that loop.

Here’s how to choose one that does and here’s a further guide on the SerpLogic site.

1. Make Sure They Understand the Amazon Algorithm (Not Just “SEO”)

Amazon runs on what’s commonly referred to as the A9 algorithm (now evolved, but the principles remain).

It prioritises:

Relevance (keyword targeting)
Conversion rate
Sales velocity
Click-through rate
Review quality
Pricing competitiveness

If an agency talks only about:

“Backlinks”
“Domain authority”
“Blog content”

…run.

Amazon SEO is on-platform optimisation first.

They should be speaking fluently about:

Title keyword stacking
Backend search terms
Attribute indexing
Browse node optimisation
CTR optimisation via main image testing
Conversion lift via A+ content

If they can’t break down indexing vs ranking vs conversion — they’re winging it.

2. Ask for Real Seller Case Studies (Not Generic SEO Wins)

At SerpLogic, we show:

Before/after ranking screenshots
Keyword tracking movement
Revenue lift data
BSR improvements

You want to see:

“Ranked page 1 for ‘collagen powder’ in 90 days”
“Improved conversion from 11% to 18%”
“Doubled organic sales without increasing PPC”

Be careful of agencies that show:

Google rankings
Website traffic graphs
Pretty dashboards with no Amazon proof

Amazon SEO is a different animal.

3. Ensure They Integrate SEO With PPC (They Must Work Together)

Here’s the secret most sellers miss:

PPC isn’t just advertising. It’s ranking fuel.

The right agency will:

Use PPC to test keyword viability
Identify converting search terms
Feed converting terms into organic optimisation
Reduce ACOS while increasing organic lift

If SEO and PPC are handled in silos — growth stalls.

You want a team that understands:
Organic + Paid = Velocity Domination.

4. Ask About Their Keyword Research Process

If their answer is:
“We use Helium 10 and export keywords.”

That’s not a strategy.

A real Amazon SEO agency will:

Segment keywords by intent (primary, secondary, long-tail)
Map keywords to exact listing real estate (title, bullets, description, backend)
Identify indexing gaps
Analyse competitor reverse ASIN data
Prioritise high-conversion terms over vanity volume

Ranking for a 50k search volume term means nothing if it doesn’t convert.

We care about revenue per impression.

5. Look at Their Approach to Conversion Optimisation

Amazon rewards listings that convert.

That means:

Main image clarity (CTR optimisation)
Benefit-driven bullet points
A+ content storytelling
Comparison charts to keep buyers on-page
Mobile-first formatting

An Amazon SEO agency that doesn’t discuss:

Image testing
Brand story modules
Emotional triggers
Price anchoring

…is only doing half the job.

SEO gets traffic.
Conversion gets profit.

6. Check If They Understand Reviews & Compliance

No serious agency will:

Offer fake reviews
Suggest manipulation tactics
Risk account suspension

They should:

Guide compliant review acquisition
Improve post-purchase flows
Optimise packaging inserts (within TOS)
Help reduce return rates

Account health is everything.

A ranking win means nothing if you get suspended.

7. Understand Their Pricing Model

Be wary of:

“£500 one-time optimisation”
“We’ll rank you in 30 days guaranteed”
Dirt-cheap retainers

Amazon is competitive. Real work takes:

Deep research
Creative assets
PPC integration
Ongoing testing

A serious Amazon SEO agency will typically:

Offer a monthly retainer
Include optimisation + strategy
Provide reporting tied to revenue, not vanity metrics

Cheap agencies optimise once and disappear.

Growth requires iteration.

8. Do They Think Long-Term Brand — Or Quick Wins?

The best Amazon sellers aren’t chasing hacks.

They build:

Brand search volume
Repeat purchase rates
Cross-sell funnels
External traffic strategies

An elite agency thinks:

How do we dominate a niche?
How do we expand keyword real estate?
How do we defend rankings?
How do we build exit valuation?

Short-term ranking spikes are fragile.

Brand authority compounds.

9. Ask Them This One Question

“Walk me through exactly how you’d optimise my listing from audit to execution.”

If they can’t give you:

A structured roadmap
A clear order of operations
A data-first reasoning
A 90-day growth model

They’re not ready.

Final Thoughts From Tommy

Choosing an Amazon SEO agency is like choosing a business partner.

You’re trusting them with:

Your margin
Your ranking
Your inventory velocity
Your brand reputation

The right agency will:

Obsess over data
Care about conversion
Understand Amazon psychology
Blend SEO + PPC + branding
Focus on revenue, not vanity metrics

At SerpLogic, we don’t chase rankings for ego.

We chase market domination.

If you’re serious about scaling on Amazon — choose an agency that thinks like an operator, not a freelancer.

Because on Amazon…

If you’re not optimised,

You’re invisible.
