How to Choose an SEO Agency: 10 Questions to Ask

The right SEO agency tells you exactly what it will do, measures results you understand, and never promises guaranteed rankings. Google publishes its own advice on hiring an SEO, and its warnings are worth knowing before you sign anything. Use the questions below to compare agencies, including us.

Why choosing carefully matters

SEO touches your website, your reputation and your visibility on Google. Google is clear that you’re responsible for what the companies you hire do on your behalf, and deceptive tactics can get a site removed from its index. A poor choice doesn’t just waste money. It can set you back.

10 questions to ask any SEO agency

1. “Can you show examples of past work?”

Google recommends asking for examples and success stories. Look for results that match your type of business, explained clearly, and shared with permission.

2. “Do you follow Google’s Search Essentials?”

The answer should be an immediate yes, with a plain explanation of what that means in practice.

3. “What will you actually do in the first 90 days?”

You should get a clear plan: an audit, the issues found, and what gets fixed first and why.

4. “How will you measure success?”

Rankings alone aren’t enough. Ask about organic traffic, leads, sales and, increasingly, visibility in AI answers.

5. “What results should I expect, and when?”

Google suggests asking about timeframes. An honest agency gives ranges and explains what drives them, rather than making promises.

6. “Do you have experience in my industry or market?”

Google recommends asking about experience with your industry, country or city. Local and international SEO need different approaches.

7. “How will you communicate with me?”

Ask how often you’ll get reports and calls, and whether they’ll explain every change they make to your site.

8. “How do you build links?”

Listen closely here. Buying links breaks Google’s spam policies. Good answers involve digital PR, genuine outreach and content worth linking to.

9. “How do you use AI?”

AI can speed up good work, but mass-produced AI pages can get you penalised. Ask who edits and fact-checks content before it goes live. Google also suggests checking that any advice on AI search (often sold as “AEO” or “GEO”) matches its official guidance, and that the agency cites Google’s own documentation.

10. “What’s the contract length, and can I leave?”

Long lock-ins protect the agency, not you. Month-to-month terms mean an agency has to keep earning your business.

Red flags Google warns about

Google’s own guide to hiring an SEO lists the warning signs. Here they are in plain English.

Green flags to look for

• They ask about your business, your competitors and how people find you today.

• They give honest timelines and explain the trade-offs.

• They show you exactly what they changed and why.

• They report on numbers that matter to your business, not vanity metrics.

• They’re comfortable with you leaving if it isn’t working.

How to compare your shortlist

Ask each agency the same ten questions, then score their answers on clarity, honesty and fit. The best agency isn’t always the cheapest or the most confident. It’s the one that explains its thinking and earns your trust before asking for a commitment.

[Founder note: add how you answer one of these questions yourself, with a real example from your process. First-hand detail like this is what Google says sets content apart.]

The bottom line

Choose an SEO partner the way you’d choose any adviser: on transparency, track record and fit. Be wary of promises that sound too good, and of anyone who won’t explain their work.

That includes us. Vantage is an AI-powered SEO agency, and we’re happy to answer all ten questions before you commit to anything. Our plans are month-to-month, so we earn your trust every month.
