More often than not, the discovery call fails even before signing a contract not because the agency did not make its case well, but because the client failed to ask enough questions. Having spent twenty minutes on polite, non-committal discussions, the two sides leave with opposing perceptions of scope, timeline, ownership, and what “results” mean.

As Google recommends when it comes to hiring an SEO, “If an SEO creates misleading content on behalf of your website, your website may be removed completely from Google’s search results. In the end, the responsibility for any action that the company performs will fall on you, so it makes sense to be sure you know exactly how they plan to ‘help’ you.” No matter what your contract says, the responsibility is yours.

Here are twenty questions to ask divided into groups to facilitate their logical progression and indications of whether you have received a good response or need to think twice.

Why do you think SEO is the right channel for my business right now?

This is what sets apart consultants from order takers. A good agency will sometimes argue that SEO does not need to be the focus right now because either the website does not convert the traffic or because the market is dominated by paid search, which will give faster results. According to Hustlefish: “Even the best SEO company out there might not be the right choice when SEO isn’t your goal.”

Strong answer: They ask about your sales cycle, margins, and current acquisition costs before recommending anything.

Red flag: Enthusiasm for SEO before they know anything about your business.

What specific problem is SEO meant to solve for us?

Greenlane Marketing frames this well: SEO should exist to solve a specific constraint lack of demand, poor visibility, weak marketplace trust, inefficient acquisition costs, or stalled growth in a competitive market. Agencies that treat SEO as an isolated channel often struggle to demonstrate holistic impact.

Strong answer: They name the constraint back to you and connect it to a measurable outcome.

How does SEO fit with our paid media, sales process, and conversion optimisation?

Search effectiveness is not an isolated phenomenon. If your webpages do not convert, then no matter how effective you are at getting high rankings, you will just be bringing more people into a failed funnel. What they should do is ask: who handles your ads, whether your CRM tracks lead source, and what happens after a form submission.

 Do you work with any of my direct competitors?

Conflict of interest is a real problem. Honest suppliers usually do not deal with rivals because these connections can affect campaign quality and lead to problems with information exchange.]

Strong answer: A clear yes-or-no, plus disclosure of adjacent clients in your sector.

Red flag: Evasiveness, or “we work with lots of businesses in your space.”

Proof and Experience

Can you show me examples of your previous work and share some success stories?

This is the first proposed question from Google when interviewing for the SEO position. [[1]] Rather than citing the examples provided on their website, ask for named clients, specific timelines, and what was done to achieve the outcome.

Good response: Named clients, results and dates, along with being willing to give a reference.

Bad response: Percentage increases without a baseline or dates or clients.

What’s your experience in my industry and my country or city?

Both these questions are classified by Google as key interview questions. The vertical experience is more important than SEO expertise because the regulations, customer behaviour, and level of competition differ greatly from one industry to another.

Good response: Give some examples and be honest about the learning experience in your job.

Warning sign: Claiming extensive knowledge about fifteen diverse industries.

May I speak to two current or former clients?

In her book, Marketing in the Age of Google, Vanessa Fox suggests asking for a short list of current and past customers along with contact information. Reference checking uncovers information that the proposals may hide and gives you a good indication of honestly and reliability

Good sign: Ready to introduce people.

Bad sign: “Our clients like it confidential.”

Can you tell me about a campaign that didn’t work, and what you learned?

Everyone makes mistakes sometimes. The reaction determines if the failures come from honest diagnoses of the problems, from the client, from the algorithm itself, or just bad luck.

Good answer: A specific campaign, a specific diagnosis, and a specific change in strategy.

Red flag: Lack of any failures, or the failures being caused only by external reasons. A good SEO company will work with their clients to find a solution.

Do you follow Google’s Search Essentials?

The question is raised directly by Google to its potential customers. In addition, the United States Chamber of Commerce emphasizes the fact that it is unacceptable to buy back links and use private blog networks; hidden content aimed at search engine manipulation is considered a violation.

Good answer: They need to understand the guidelines and show how their strategies fit into these guidelines.

Red flag: The idea of “Google guidelines being more like suggestions.”
