Choosing an SEO agency is a business decision about who will diagnose your site, recommend changes, and remain accountable for the work. Begin with your goals and access to reliable data. A persuasive ranking promise or a long automated audit is not enough to judge the team.
Define the outcome you need
Write down your main business goal, priority markets, services or products, budget range, and internal constraints. Is the immediate need a migration, technical cleanup, local visibility, content strategy, or ongoing growth? Decide who on your team can approve website changes and provide development support. An agency cannot implement a useful roadmap if no one owns the site.
Choose measurements connected to that goal: qualified organic enquiries, revenue, calls, relevant landing-page visits, and Search Console trends. Keyword rankings can provide context, but a single broad phrase should not define success. Establish the baseline before a proposal changes the site.
Ask for a diagnosis, not a guaranteed position
A good candidate should explain what they would inspect first, what evidence they need, and which findings are still hypotheses. Ask them to review a few important pages, Search Console access, and a representative competitor set. They should distinguish urgent technical blockers from longer-term content opportunities. Our SEO audit report template shows the level of evidence and ownership a useful report should provide.
Google’s guide to hiring an SEO warns against guaranteed rankings and encourages asking for explanations of recommendations. No agency can buy a special organic position or guarantee Google will index every page.
Questions to ask in the interview
- What would you inspect in the first 30 days, and what access do you need?
- Who performs the audit, writes recommendations, implements changes, and reviews quality?
- Can you show a relevant example with the problem, method, and measured outcome, while protecting client confidentiality?
- How do you prioritize work when development resources are limited?
- How will you coordinate content, design, and engineering approvals?
- What will the monthly report show, and how will you explain a decline?
- What happens to assets, access, and documentation when the engagement ends?
Listen for specific answers and reasonable uncertainty. A team that can explain how it would verify a redirect, canonical, or local profile change is more useful than one that promises a fixed traffic percentage without inspecting your site.
Examine the proposal line by line
A useful scope states deliverables, cadence, responsibilities, assumptions, and dependencies. “Technical SEO” may mean a one-time crawl or ongoing implementation support. “Content” may mean briefs, writing, editing, publishing, or only recommendations. Ask for the actual number and type of deliverables, revision process, and who owns final approval.
Clarify whether link building includes outreach, placements, sponsorships, or digital PR. Require disclosure of paid placements and their treatment. Avoid tactics that put your domain and reputation at risk. If the agency proposes AI search services, ask how it separates official Search Console data from sampled third-party observations.

Check reporting and access
Keep ownership of your domain, hosting, analytics, Search Console, Google Business Profile, and key accounts. Grant the least access needed, with named users and a clear offboarding process. Agree on a change log for releases and major edits. The agency should share what changed, why, who approved it, and how the result was checked.
A monthly report should separate completed tasks from search outcomes. It can show affected page groups, indexing status, qualified visits, conversions, and next decisions. Compare equivalent periods and explain seasonality, site changes, and measurement limits. The Search Console audit workflow
Red flags to investigate
- A guaranteed #1 ranking, instant indexing, or a secret relationship with Google.
- A proposal based only on a tool score with no inspection of important pages or business goals.
- Unclear ownership of purchased domains, content, listings, or accounts.
- Large volumes of near-duplicate pages or undisclosed paid links.
- Refusal to explain recommendations or provide a change log.
- A contract whose cancellation and asset handoff terms are unclear.
One red flag is a reason to ask for detail, not always an automatic verdict. Compare the written answer, references, proposed work, and contract before deciding.
Run a small, reviewable first phase
For a substantial engagement, start with a diagnostic phase and a prioritized roadmap. Agree on two or three measurable fixes, the people responsible, and how each will be validated. This gives both sides a concrete way to assess communication and execution before expanding scope.
Review the plan against your resources and the actual site. The best agency for a complex migration may differ from one suited to a local service business. Select the team whose process, expertise, and working style fit the problem you need solved.
A comparison sheet
Score candidates on relevant experience, quality of diagnosis, clarity of scope, implementation capacity, reporting, account ownership, communication, price, and contract terms. Use notes and evidence rather than a single weighted number that hides tradeoffs. Ask all candidates the same core questions.
