AI marketing is the category with the most self-declared "AI companies" and, honestly, the most AI-washing. Here's how to separate real capability from a rebranded traditional agency.

Step 1: Understand what AI marketing should actually change

A genuine AI-powered marketing partner changes the process, not just the output — faster audience modeling, real-time bid optimization, AI-assisted content drafting with human strategic oversight, and increasingly, optimization for how AI search tools (ChatGPT, Perplexity, Google AI Overviews) surface and cite brands. If a proposal only mentions AI as a tool for writing blog posts faster, that's a narrow (and increasingly commoditized) use of it.

Step 2: Ask for the automation-to-human ratio, explicitly

Ask: "What percentage of what you deliver is AI-generated, and what does human review look like before it ships?" There's no universally "correct" answer, but a vague one is a red flag. The strongest agencies can walk you through their workflow step by step.

Step 3: Understand current pricing benchmarks

Recent agency-market research suggests small businesses typically pay in the $500–$2,000/month range for basic AI automation and templated services; small-to-mid-sized companies often pay $2,000–$10,000/month for dedicated account management and custom AI-assisted content; mid-market firms often invest $10,000–$50,000/month for custom model training and data pipeline work; and large enterprise deployments frequently run $50,000/month and up. [ILLUSTRATIVE — verify against current published rate cards before publishing as platform guidance.] Use these as a sanity check against quotes you receive, not a fixed rulebook.

Step 4: Check for answer-engine optimization competency

With over half of B2B buyers now starting research with an AI chatbot rather than a search engine (per G2), ask candidates directly how they structure content and digital assets so AI search tools cite your brand accurately — this is a distinct, newer skill from traditional SEO, and not every "AI marketing agency" has actually built it.

Step 5: Compare across category leaderboards, not one list

Marketing-adjacent AI work often spans multiple categories. Cross-check candidates against the digital marketing top leaders page, and if the engagement includes a web or e-commerce component, check the web development and e-commerce development leaderboards too — the strongest AI marketing partners often show up favorably across more than one category.

Step 6: Read the reviews for specifics, not sentiment

A five-star review that only says "great team!" tells you less than a three-star review that explains exactly what went wrong and how it was resolved. When reading agency reviews — including on C2Creview — look for detail, not just star rating.

Quick red-flag checklist

? Can't name the specific models or platforms they use

? Pricing bundles platform/API costs with strategy fees

? No answer for "what didn't work on a past project"

? References are all hand-picked, none independently verifiable

? Can't explain their AEO/GEO approach when asked directly

If an agency clears all five, you've likely found a genuine AI marketing partner rather than a traditional agency wearing an AI label. For agencies confident they meet this bar, listing on C2Creview is a direct way to be evaluated against it — and buyers can check current write-a-review submissions on the write a review page for the latest verified feedback.
