SEO is an industry with an unusually high proportion of agencies that cannot deliver what they promise. Promises of first-page rankings, guaranteed results, and quick wins are standard sales language — and almost always misleading. These twelve questions are designed to separate agencies that actually understand how modern SEO works from those selling a service they cannot deliver.
Questions about their approach and process
Walk me through exactly what you do in the first 90 days of an SEO engagement.
How do you approach technical SEO audits and what tools do you use?
What is your content strategy process — do you produce content, direct it, or just advise?
How do you build links, specifically? What tactics do you use and what do you refuse to do?
How do you prioritise what to work on first — what is your decision-making framework?
The link-building question is the most revealing
Ask exactly how they build links. Agencies that rely on private blog networks (PBNs), mass directory submissions, or purchased links are using tactics that will eventually result in Google penalties. A credible SEO agency will describe a process centred on earning links through content quality, digital PR, and genuine relationship building — and will be specific about it.
Questions about their track record
Can you show me two or three case studies with specific traffic and ranking data — including the timeline?
Have you worked with businesses in our industry or with similar competitive landscapes?
What is your average client retention rate and what is the most common reason clients leave?
Can you provide two client references I can speak to directly?
Questions about reporting and accountability
What does your monthly reporting cover and what metrics do you use to define success?
How do you handle a situation where results are not coming through after three or four months?
What access and ownership do we have — to the content, the links you build, the data?
Red flags that should end the conversation
They guarantee specific rankings or traffic numbers. Nobody can guarantee Google rankings.
They are vague about their link-building process and change the subject when pressed.
Their case studies have no dates, no baseline data, and no methodology.
They promise results in 30 days. Real SEO compounds over months, not weeks.
They cannot explain what they will do differently from what you are already doing.
Their own website ranks for nothing relevant and looks as though no SEO work has been done on it.
They send a proposal without asking about your current technical setup, existing content, or competitive landscape.
What good SEO agency answers sound like
A credible SEO agency will tell you: that results typically take three to six months to become visible, that the first priority is a technical audit and fixing structural issues, that content strategy is central to long-term performance, and that link acquisition will be earned through quality rather than purchased. They will be honest about what they cannot control — algorithm updates, competitor behaviour, timeline certainty — and clear about what they can control and how they will do it. Any agency that is honest about the limitations of the discipline is more trustworthy than one that promises the impossible.
