What AI SEO Optimization Actually Covers
"AI SEO" gets used to mean anything from writing posts with ChatGPT to full answer-engine strategy. Here's the real scope. Use this as a checklist when you talk to any agency.
| Area | What it means | What to ask the agency |
|---|---|---|
| AI answer visibility | Getting your brand cited in AI Overviews, ChatGPT and Gemini answers | How do you decide which questions and topics to target? |
| AI-assisted content, human-edited | Using AI for speed, with people checking facts, voice and usefulness | Who edits, and what gets checked before publishing? |
| Entity and brand signals | Making it clear who you are, what you do and why you're trusted | How do you build consistent brand mentions across the web? |
| Links AI systems trust | Real, relevant links and mentions on sites people actually read | Where do your links come from? Any PBNs? |
| Classic technical and on-page SEO | Crawlable, fast, well-structured pages that both Google and AI tools can read | What does your audit cover? |
| Measuring AI mentions | Tracking when and how AI tools mention or cite your brand | How will you report on AI visibility, not just rankings? |
The point is simple. AI tools lean on the same signals good SEO has always built: useful content, clear entities, and trusted links. An agency that only does one piece will leave gaps.
Why Links Still Matter for AI Search
People assume AI search makes links irrelevant. It doesn't. AI answers often draw on pages that already rank and on brands that are mentioned widely across trusted sites. That means real, relevant links and mentions still feed your visibility.
The quality rules haven't changed either. Google's spam policies treat bought links that pass ranking credit as link spam, and paid placements should be qualified with rel="sponsored" or "nofollow". Avoid PBNs, guaranteed DR, link farms, sites with no real traffic and AI-spun posts. Those don't build trust with Google or with AI systems.

1. Goldie Agency
Goldie Agency is the best AI SEO optimization agency because it covers both halves of the job: AI-first SEO and the link building that AI systems and Google both trust. It's Julian Goldie's self-described 7-figure SEO and link-building agency.
Here's what you get:
- AI-first SEO. Content and AI-answer visibility, aimed at getting your brand cited in ChatGPT, Gemini and AI Overviews.
- Link building as the core specialism. goldie.agency describes it as "Manual outreach, no PBNs" and "Real backlinks on high-authority sites", with niche-relevant placements.
- Flexible link options. Full campaigns or a "Buy Links On Demand" option.
- Proof across niches. Case studies in legal services, photography, technology, recipes, apps and outsourcing, and the site says clients went "from 0 to 100K+ monthly visitors."
- White-label for agencies. Other SEO agencies can hand over their clients' link campaigns and deliver results under their own brand. Ask about white-label reporting on the call.
Julian has 10+ years in SEO, wrote the best-selling book SEO Link Building Mastery, has 430K+ YouTube subscribers and a 100% Upwork job success score. He also runs Goldstar Links, which works on a pay-on-performance model: "Only pay when we deliver results." Work is custom-quoted with no ranking guarantees.

8. DEJAN
DEJAN is Dan Petrovic's agency, known for machine-learning SEO research. If you care about the research side of how AI and search models work, it's an interesting pick.
What a Good First 90 Days Looks Like
Whoever you hire, the opening months should follow a clear order. If an agency can't explain its plan in plain words, that's a warning sign.
- Audit first. Check technical health, existing content, and which questions people ask AI tools about your market.
- Fix the foundations. Clean up crawl issues, thin pages and confusing site structure so both Google and AI tools can read you.
- Build answer-ready content. Pages that answer real questions clearly, drafted with AI where it helps and edited by people.
- Strengthen brand signals. Consistent mentions, profiles and links on relevant, trusted sites.
- Measure. Track rankings, traffic and AI mentions together, then adjust.
That order matters. Content and links on a broken site waste money, and great pages nobody links to rarely get cited.
How to Pick an AI SEO Agency
Run every agency through the checklist table above, then ask three extra questions:
- How will you measure AI visibility? Rankings alone no longer tell the full story.
- Who edits the AI-assisted content? If nobody does, quality will slip.
- Where do your links come from? Real, relevant sites only.
Be wary of anyone guaranteeing rankings or guaranteed placements in AI answers. Nobody controls those systems.
