What questions reveal an SEO company's expertise?
Questions that cannot be answered from a script: ones that ask the company to prioritize, to diagnose a symptom, to say what it does not know, and to support a claim about Google with a source. Standard interview questions show whether a company is organized. These show whether the people answering understand search. Listen for reasoning rather than vocabulary. A shallow answer names tools and tactics; an expert answer connects a symptom to a cause that can be tested and explains the tradeoffs.
How would you prioritize?
Ask: “If an audit found ten technical issues, how would you decide which three to fix first?” There is no single right answer, so a memorized response breaks down quickly. A shallow answer works down the list or sorts by a generic severity label. An expert answer asks which pages bring in inquiries or sales, how many pages each issue affects, and how much effort each fix takes, and explains why a small problem on an important template can matter more than a large problem on pages nobody visits.
Where would you look first?
Give a realistic symptom and ask them to think aloud: “Impressions for one section of the site fell, but rankings for our main terms look stable. Where would you start?” A shallow answer jumps to a cause, such as an algorithm update, or a fix, such as more content. An expert answer treats it as an investigation: when the fall began, which pages and queries it affected, what Search Console’s indexing reports show for that section, whether anything on the site changed at that time, and whether demand for those searches changed. The willingness to gather evidence before naming a cause is the signal.
What can’t you be sure of?
Ask how confident they are that a recommended change will improve rankings, or how they would forecast results. A shallow answer promises outcomes and dates. An expert answer explains which parts depend on Google, competitors, and the way results are displayed, gives ranges rather than single figures, and describes how the change would be tested and measured.
What changed in search recently, and where does Google say so?
Ask the company to name a recent Google update and explain what it changed in their work. Google lists its ranking updates, with dates, on its Search Status Dashboard, so you can check that the update they name is real. Then listen to how they describe it. Google’s page on core updates describes them this way: “These changes are broad in nature, and don’t target specific sites or individual web pages.” If a company tells you precisely what a core update rewarded or punished, ask where Google said so. An expert separates what Google has stated from what the industry has guessed.
Can you show us a result and its evidence?
Ask for one example of their own work: the problem, what they changed, when, and what happened afterwards, shown in the client’s Search Console or analytics with the dates visible. Then ask what else might have caused the improvement. A company that has thought about other explanations, such as seasonality or a competitor’s decline, understands what its results do and do not prove.
How to listen
The same habits mark an expert answer to each question: asking for the facts before answering, naming what would be checked and in which report, stating uncertainty plainly, and separating Google’s statements from opinion. A confident answer without any of these is a sales answer, however fluent it sounds.
