Black Propeller review
PPC-focused agency with transparent tiered-fee logic and a large library of conversion, CPL, revenue, and ROAS cases.
No published price we can link to. We do not estimate one — ask on the call, and see the pricing-transparency line in the scores below.
Verdict
Black Propeller is a strong performance-marketing candidate because its proof goes beyond traffic: published cases report lower cost per conversion, more purchases, increased revenue, and ROAS gains across many industries. The monthly fee changes only with material ad-spend changes, which is clearer than percentage-only pricing. Verify account access, creative allocation, and whether the named team has experience in the buyer's vertical.

What other platforms say
Extensive first-party performance evidence and a clear fee model; independent rating detail should be reconfirmed during procurement.
These are other platforms' numbers, not ours. We report them because they are part of the picture, and we do not average them into our score — our score comes from the published rubric above.
Red flags
- Case metrics are vendor-published
- Broader SEO services should not blur paid-channel accountability
How it scored
Vertical & stage fit
The result library covers local services, healthcare, ecommerce, travel, real estate, and other verticals.
Channel depth (not breadth)
PPC and performance advertising are core, with supporting SEO and social capabilities.
Attribution & measurement
Cases report conversions, cost per conversion, CPL, purchases, revenue, and ROAS.
Creative capability
Campaign and landing-page execution are visible, while pure creative-studio depth is secondary.
Account ownership & seniority
A managed specialist team is clear, but exact senior time requires proposal confirmation.
References & verifiable case studies
The official result library contains dozens of named cases and measurable outcomes.
Contract & pricing transparency
The agency states retainers use consistent monthly tiers that change only when ad spend changes significantly.
What we could not verify
- Current minimum retainer
