How to Vet an SEO Agency
Most SEO agency pitches sound the same. Here's the list of specific questions that separate a genuine partner from a well-rehearsed sales deck.
Most businesses will work with more than one SEO agency before finding a good fit. That’s an expensive way to learn, not just in retainer fees, but in months of momentum lost, content that needs to be redone, and the hesitation it creates around investing in SEO again at all.
Almost every agency pitch sounds confident and almost identical on the surface. The difference between a genuine partner and a mediocre one shows up in how they answer specific, slightly uncomfortable questions. Ask these before you sign anything.
“Will I have direct access to the people actually doing the work?”
A common and quietly damaging pattern: a senior strategist runs the pitch and impresses you, then disappears after signing, replaced by a junior account manager you’ve never met. Ask specifically who will be doing the technical work, the content, and the strategy, and whether you’ll have any direct line to them. A vague answer here is worth taking seriously. A specific, confident one is worth a follow-up conversation.
“What did your audit actually find on our site?”
If an agency proposes a fixed package or a set price before auditing your site, your competitors, and your market, that’s a generic package, not a strategy built for you. A legitimate agency’s proposal should reference specific things they found: technical issues, content gaps, competitor weaknesses. If the pitch could apply word-for-word to any business in your industry, it probably was written that way.
“Can you show me one verified example of AI Overview or AI citation results?”
By 2026, nearly every agency pitch mentions AI search optimization somewhere. Ask for one concrete, checkable example: a query where their own brand, or a client’s, is actually cited in an AI Overview or a ChatGPT-style answer as a direct result of their work. If they can’t produce a single verifiable instance, the capability is marketing language, not something they can actually deliver yet.
“What happens to our links if we ever leave?”
This question tends to get an honest agency talking normally about backlink strategy, and gets a bad one visibly uncomfortable. If any part of your future rankings would depend on links placed on properties the agency itself owns or controls, those links, and the rankings they support, can disappear the moment you cancel. Ask directly where links come from and who owns those placements.
“What does your reporting actually look like? Can I see a real sample?”
Ask for an actual, real (or realistically anonymized) monthly report from an existing client, not a template built for the sales process. This tells you more about what your relationship will actually feel like than anything said out loud in the pitch meeting.
“What would make you tell me this isn’t working?”
This is the single most revealing question you can ask, and almost nobody asks it during the sales process. Every SEO engagement has periods that underperform. A trustworthy agency has already thought about what a genuine failure looks like and how they’d tell you. An agency that only has an answer about “when it starts working” and nothing about what failure would look like hasn’t thought about your relationship past the signature.
“Can I speak to a current client, not just a past success story?”
Case studies are curated by definition. A current client, ideally one who’s been with the agency for six months or more, will tell you what the actual month-to-month relationship is like, not just the highlight reel. Reluctance here is worth noting, though reasonable agencies do have legitimate confidentiality constraints, so weigh this one alongside the others rather than alone.
What the answers actually tell you
None of these questions are designed to trick anyone. A genuinely good agency will answer most of them comfortably, because they’ve already had to think about these exact issues with existing clients. The value isn’t in any single answer. It’s in the pattern: specific, confident, and slightly uncomfortable answers usually mean you’re talking to people who do the work they claim to. Vague, deflecting, or overly polished answers to the same questions usually mean the pitch was the product.
