Everyone's selling AI marketing. But how many AI marketing agencies are actually visible in the AI search results they promise to optimize for?
We decided to find out.
Methodology
We tested 20 AI marketing agencies across 12 high-intent queries in ChatGPT (GPT-4o) and Perplexity. The queries represent what a SaaS founder would actually ask when looking for marketing help:
Queries tested:
- "Best AI marketing agency for SaaS startups"
- "Top AEO agency"
- "Best answer engine optimization agency"
- "AI marketing agency for startups"
- "Best marketing agency for B2B SaaS"
- "AI SEO agency for tech companies"
- "Marketing agency that optimizes for ChatGPT"
- "Best growth marketing agency for SaaS"
- "AEO services for startups"
- "Who are the top AI marketing agencies"
- "Best marketing agency for AI visibility"
- "Affordable AI marketing agency"
Agencies tested: Single Grain, NoGood, NinjaPromo, Directive, Omniscient Digital, First Page Sage, Graphite, Daydream, Revv Growth, Omneky, SmartSites, BetterAnswer, iPullRank, Minuttia, Marcel Digital, Growth Plays, GreenBanana SEO, Hatter AI, 42DM, Embarque.
For each query, we recorded whether the agency was mentioned by name in the AI response.
Key findings
Finding #1: Only 4 out of 20 agencies appear in more than half the queries
The vast majority of AI marketing agencies — including several that sell AEO as a service — are invisible in AI search for their own category.
| Visibility tier | Agencies | Cited in X/12 queries |
|----------------|----------|----------------------|
| High visibility | NoGood, Single Grain | 7-9 out of 12 |
| Medium visibility | NinjaPromo, First Page Sage | 4-6 out of 12 |
| Low visibility | Directive, Omniscient Digital, Graphite | 2-3 out of 12 |
| Not cited | 13 out of 20 agencies | 0-1 out of 12 |
Finding #2: Perplexity and ChatGPT cite different agencies
ChatGPT tends to favor agencies with strong brand mentions across listicles and news articles. Perplexity leans heavily on Reddit discussions and recent blog content.
ChatGPT top results: Single Grain, NoGood, NinjaPromo
Perplexity top results: NoGood, First Page Sage, Single Grain
Only 2 agencies (NoGood and Single Grain) appeared consistently in both.
Finding #3: Listicle presence is the #1 predictor of AI visibility
The agencies that show up most are the ones listed in the most "best of" articles across high-authority sites. This confirms what the data already shows: listicles account for 21.9% of all AI search citations — more than articles (16.7%) or product pages (13.7%).
Agencies with 10+ listicle placements: Single Grain, NoGood, NinjaPromo
Agencies with 2-5 listicle placements: Most others
Agencies with 0-1 listicle placements: Invisible in AI search
Finding #4: Reddit presence directly correlates with Perplexity visibility
Reddit is Perplexity's #1 citation source (43% of top-10 results). Agencies that are actively discussed on r/marketing, r/SEO, and r/SaaS subreddits appear significantly more in Perplexity results.
Finding #5: Most AEO agencies haven't done AEO for themselves
This is the most striking finding. Several agencies that charge $10,000+/month for AEO services don't appear in AI search results when you ask about their own category. It's the equivalent of an SEO agency that doesn't rank in Google.
What this means for SaaS founders
If you're hiring an AI marketing agency, the first thing you should do is test them:
- Ask ChatGPT: "What are the best AI marketing agencies for SaaS startups?" — is the agency mentioned?
- Ask Perplexity: Same query — different results, check both.
- Google: "best AI marketing agency" — are they in the listicles that appear?
- Reddit: Search their name on r/marketing — do people talk about them?
If an agency claims to do AEO but fails all four tests, that's a red flag.
The 3 traits of agencies that actually show up
Based on our research, high-visibility agencies share three common traits:
1. They're in the listicles.
Not just one — they're placed in 10+ "best of" roundups across Clutch, G2, industry blogs, and publication sites. This is active outreach work, not passive.
2. They have community presence.
They're discussed on Reddit. Their founders are active on LinkedIn and Twitter/X. They show up in podcast interviews. This creates the citation signals that LLMs pick up.
3. They publish original research.
Unique data, benchmarks, and studies that other publications cite. This builds entity authority — the LLM equivalent of backlinks.
Limitations
This research has a few important caveats:
- LLM responses vary by session. We ran each query 3 times and recorded the most consistent result, but AI responses can change.
- Knowledge cutoffs matter. New agencies may not appear due to training data recency.
- This is a snapshot. AI search is evolving rapidly. Results from April 2026 may differ from results in July 2026.
- We're a competitor. itscool.ai is an AI marketing agency. We've tried to be as objective as possible, but you should verify our findings independently.
Conclusion
The AI marketing agency landscape in 2026 is crowded but visibility is concentrated. A small number of agencies dominate AI search results, and they do so through the same tactics they should be executing for clients: listicle placements, community presence, and original research.
For SaaS founders, the takeaway is simple: before hiring an AEO agency, check if they've done AEO for themselves.
