Questions to Ask an SEO Agency (and When to Ask Them)

Questions to ask an SEO agency can help you separate a capable SEO partner from a polished sales team, but only if you ask those questions at the right time.

You can work through 20, 30, or even 50 questions from an SEO checklist and still hire the wrong agency. The problem is not the questions themselves. The problem is when and how you ask them.

SEO agencies control the typical discovery call. Their sales teams have run the same conversation hundreds of times, while you may only hire an SEO agency once every few years. They know the common questions, they have prepared convincing answers, and they know how to make those answers sound specific to your business.

That makes the standard discovery call a poor place to judge an agency on words alone.

Instead, test what they can prove. Ask questions before the call, request evidence afterward, challenge specific claims in the written proposal, and speak with a former client before you sign. These situations force an agency to move beyond rehearsed answers and show you how it actually works.

Below, you will find the best questions to ask an SEO agency at each stage of the hiring process, along with the answers strong agencies give, the red flags to watch for, and the evidence you should demand before committing your budget.

The list is not the problem

Every question in every “20 questions to ask an SEO agency” post has been asked of your shortlist before. They have prepared responses. That is not dishonesty, it is just sales.

Three things resist preparation:

Artifacts. A report they sent last quarter, a link they built, a ticket they wrote. These already exist or they do not.
References. Specifically the ones the agency did not hand-pick.
Contract language. What a firm will put in writing is the only claim that survives the relationship.

Structure your vetting so the heaviest questions land where those three live.

Stage 0: Three questions for yourself, before any call

Agencies give better answers to buyers who know what they want.

What outcome makes this spend obviously worth it? Not traffic. Booked demos, qualified leads, store visits, revenue. Write the number down. If you cannot name it, an agency will happily sell you rankings instead, and rankings are easy to deliver in ways that never reach your bank account.

What can you actually supply? Developer hours, subject-matter experts for interviews, someone who can approve content in under a week. A strategy that needs 40 hours a month of your team fails if you have five.

What is your floor budget and time horizon? Below a certain retainer you are buying tactics, not strategy. In the United States, the median cost of SEO services is $1,501 to $2,000 per month, according to Ahrefs’ survey of 439 SEO providers; agencies average about $3,209 per month.

Stage 1: Five questions for the 30-minute call

Keep the call short and ask only what resists a script.

1. “What did you find when you looked at our site before this call?”

Ask it first. It is the highest-signal question on the list because it measures effort, not knowledge.

Strong answer: Two or three concrete observations. Your category pages are competing with each other for the same term. You have 400 indexed pages and 30 get impressions. A competitor owns the comparison queries you should own. They may be wrong, but they are wrong specifically.

Worry when: They open a tool live on the call and read numbers back to you, or the answer is a horoscope that would fit any website (“your on-page needs work and your backlink profile is weak”).

2. “What would you deliberately not do in the first 90 days?”

Everyone can list what they would do. Restraint requires a point of view.

Strong answer: “No new content in month one. We fix indexation and internal linking first, so anything we publish later has somewhere to sit.” Or the reverse, with a reason attached.

Worry when: The plan is everything at once. Agencies that start eight workstreams in parallel cannot tell you in month six which one moved the number.

3. “Who does the work, by name, and how many accounts do they carry?”

The strategist on the sales call is often not the strategist on the account.

Strong answer: A name, a role, a rough allocation, and an honest note about what is subcontracted. A real number for account load, stated instantly, usually somewhere between five and fifteen.

Worry when: “You’ll have a dedicated team.” Ask again. Then ask whether the senior person on this call will be on your monthly call in month seven.

4. “Tell me about an engagement that underperformed. What did you change afterward?”

Strong answer: A story with a diagnosis. “We assumed the problem was content, spent four months on it, and the real issue was faceted navigation eating crawl budget. Our audit checks that first now.”

Worry when: There are no failures, or every failure is the client’s fault. Any agency operating for three years has been fired. A clean record means someone is editing.

5. “Under what conditions would you tell us SEO is the wrong spend right now?”

Strong answer: Real disqualifiers. A two-day buying cycle. A category with almost no search demand. No development resource to ship fixes. A budget too small for the competitiveness of the space.

Worry when: Nothing about your business gives them pause. An agency that takes every client has no thesis about where it wins, and you will pay for the learning curve.

Stage 2: The paper trail

This is where most vetting stops and where the real information starts. After the call, request four artifacts by email. Each takes a good agency minutes to send and a weak one cannot produce at all.

1. A redacted monthly report from last quarter. Not a dashboard screenshot. You are checking whether the report explains anything: what we did, what moved, what did not and why, what changes next month as a result. Forty charts is not forty insights. A three-page report with a clear narrative beats an automated export every time.

2. Five live backlink URLs built in the last 90 days, with the mechanism behind each. Backlinks are public, so “client confidentiality” is not a reason to withhold them. Open all five. Are they on pages a human would read? Is there a sponsored tag at the bottom of each? Some will be unglamorous, which is fine. What you want is an honest account of how each was earned: a data study picked up by a trade publication, a founder quote placed through a journalist request, a broken-link replacement on a resource page. A refusal to name mechanism usually means a paid placement network, and manual-action risk lands on your domain rather than theirs.

3. A technical ticket or implementation spec they wrote for a client’s dev team. This tells you whether their technical SEO ends at diagnosis. A useful ticket names the affected templates, the expected behavior, the acceptance criteria, and how the fix gets validated after release. A spreadsheet row that says “fix canonicals” is not an implementation plan, and your engineering team will treat it accordingly.

4. Three pieces of content published in the last month, ideally near your category. Read them. Do they say anything a competent generalist could not have written from the top ten results? Is there original data, a named author, a real example, a defensible opinion? Technically optimized writing that says nothing distinctive is still weak content, and it is now the most common failure in the industry.

If an agency sends all four inside two business days, you have learned more than three additional calls would have told you.

Stage 3: Questions for the proposal, not the pitch

Once you have a written scope, the questions change. Now you are testing whether what they described is what you would actually buy.

“Could a competing agency price this scope from your proposal?” If the deliverables read “ongoing optimization” and “content,” nobody can. Get units: number of pages, number of technical tickets, hours by function, meeting cadence, who publishes. Then divide the retainer by the implied hours and check the effective rate.

“Which single metric should we be judging you on in month nine?” Force a choice. Strong answers are qualified organic sessions to commercial pages, organic-sourced pipeline, or non-brand organic revenue. Rankings are a leading indicator, not a result, and an agency that leads with keyword positions has selected the metric easiest to move without helping you.

“How will you separate branded from non-branded organic performance?” This question quietly sorts the field. Branded search rises when you run a podcast ad, announce funding, or get written about, and plenty of monthly reports take credit for it. Non-branded performance is the closer read on whether SEO is reaching people who did not already know you.

“Who implements technical fixes, and what happens if our developers cannot ship for a quarter?” More retainers die here than anywhere else. The agency delivers 40 recommendations, your roadmap is full, and nothing ships for eight months while you keep paying. Either they implement in your CMS, or they scope the developer time they will need from you and put that estimate in writing before you sign.

“Where does AI sit in your content process, and who is accountable for what gets published?” AI-assisted production is not disqualifying. An unreviewed pipeline is. You want a defined line: research and outlining assisted, drafting and subject-matter substance human, a named author who can defend the piece, a fact-check step before publication. Be equally skeptical of a flat “we never use AI,” which is unverifiable and slightly odd.

“What are you doing about visibility in AI Overviews and assistants, and how do you measure it?” Ahrefs analyzed 146 million Google SERPs and found that AI Overviews appeared for 21% of all keywords and 57.9% of question-based queries. A credible answer connects AI visibility to the same fundamentals that support search performance: crawlable pages, clear entity and brand signals, structured data where it applies, original information that cannot be paraphrased from elsewhere, and citations on the third-party sites these systems draw from. It also admits that measurement is immature and directional. Anyone selling guaranteed AI citations through a proprietary method is describing a product that does not work the way they say it does.

Stage 4: References and contract terms

Save these for last. They are worth the most and cost the agency the most to answer.

Ask for two specific references

Not the ones they offer. Ask for a client past month 12 and a client who left. Then ask the reference:

What surprised you in the first 90 days?
What took longer than the agency estimated?
Who shows up to the monthly call now, compared with month one?
How much work landed on your side, and were you warned in advance?
Would you hire them again for the same scope, a bigger one, or something narrower?

That last one does the heavy lifting. It gives the reference permission to be honest about limits without trashing anyone.

Get four things in writing

Term and exit. A twelve-month agreement with a 30-day out is friendlier than a six-month agreement with no out at all. SEO does compound slowly, which is an argument for patience, not for removing your leverage. A reasonable structure is a three to six month initial term, then monthly with 30 days’ notice.

Ownership. Google Analytics, Search Console, Google Business Profile, your CMS, and any tracking properties should be registered to your company, with the agency added as a user. Not the reverse. Content, source files, keyword research, audit documents, and dashboards built on your data should be assigned to you.

Link durability. Ask directly: “If we stop paying, which links disappear?” Rented placements vanish with the invoice. That is a subscription, not an asset, and knowing which part of your profile is rented changes what the retainer is actually worth.

Competitor exclusivity. Either a clause or a clear explanation of how overlapping accounts are walled off. Finding out later is the bad version.

Red flags that end the conversation

Individual weak answers happen. Patterns do not.

Guaranteed rankings, guaranteed positions, or guaranteed placement in AI answers. Nobody controls the index. Google explicitly warns that “No one can guarantee a #1 ranking on Google” and says it does not guarantee that it will crawl, index, or serve a page, even when that page follows Search Essentials.
“We have a special relationship with Google.”
A Google Partner badge presented as an SEO credential. That badge covers Google Ads. There is no organic equivalent.
A full proposal and price before any diagnosis, which means the scope was written before they met you.
Deliverables measured only as outputs: eight posts, 20 links, one report.
Refusal to name the people doing the work, or to let you meet them.
Reporting that leads with impressions and keyword counts and never reaches conversions.
Evasion about where links come from.
Discount pressure with a deadline attached.

The questions a good agency asks you

Vetting runs both ways. On a strong call, you should be answering:

What is your average order value or contract value, and your close rate?
What does a qualified lead look like, and what percentage of current leads are junk?
Who owns the website, and how quickly can changes ship?
What have you already tried, and what did you conclude from it?
Which competitors do you lose deals to?
Do you have internal experts who can be interviewed for content?
Can you handle a large increase in inbound volume?

An agency that asks only about budget and login access is scoping an invoice, not a strategy.

Score them the same day

Rate every finalist on the same five dimensions, one to five each, within an hour of the call while the hedges are still fresh.

Dimension	What you are scoring
Diagnosis	Did they find something specific about your site before you paid them?
Evidence	Did the four artifacts arrive, and did they hold up?
Executor access	Do you know who does the work, and did you meet them?
Measurement	Did they tie the work to business outcomes and admit attribution limits?
Exit terms	Would leaving in month six be painful or merely inconvenient?

Three or more scores below a 3 is a pass, regardless of how good the deck was. If two finalists tie, apply the tiebreaker: which team would you rather get bad news from? Every engagement produces some.

The takeaway

Deciding which SEO agency questions to ask is the easy half. The harder half is asking them where an agency cannot perform: in writing, against artifacts, with a former client, and inside a contract.

Specificity is the whole test. Agencies that know what they are doing get more precise under pressure. The rest get more enthusiastic.

Next step: pick your five call questions, send them to your shortlist in advance, request the four artifacts by email the same afternoon, and score every finalist on one sheet before you sign anything. The agencies that prepare well for your questions are usually the ones that manage accounts well, and the ones who resent the homework have told you something useful for free.

Frequently Asked Questions About the Questions to Ask an SEO Agency

What questions should I ask an SEO agency before hiring?

Start with the five that resist scripting: what they found on your site before the call, what they would deliberately not do in the first 90 days, who does the work by name, an engagement that underperformed, and when they would tell you SEO is the wrong spend. Then move to artifacts, proposal scope, references, and contract terms.

How many agencies should I talk to?

Three, as long as all three answer the same questions and get scored the same way. Past five, the calls blur.

Is it a red flag if an agency refuses to guarantee rankings?

The opposite. Refusing is the honest answer. Guaranteeing means either targeting terms nobody searches or accepting risk that lands on your domain.

How long before SEO produces results?

Technical fixes can move things in weeks. Content and authority usually take two to three quarters to compound, longer in competitive or regulated markets. Ahrefs’ poll of 3,680 marketers and SEOs found that SEO typically takes three to six months to start showing results. Google adds that some improvements can appear within days, while broader site-level changes may take several months for its systems to recognize. Ask for a forecast with its assumptions stated, then check it at month four against the plan.
