How do I choose the right SEO agency?

Look for verifiable results and genuine reviews, a clear explanation of the monthly work, a safe approach to link building, transparent reporting focused on leads and sales, and fair contract terms. Always ask to see case studies.

What should I ask an SEO agency before hiring?

Ask what they'll do each month, how they build links, how they measure success, who will work on your account, what the contract terms are, and whether they can show results for similar businesses.

What should I expect from an SEO agency?

Expect an audit and strategy upfront, regular technical, content and link-building work, and clear monthly reports. Early improvements often appear within three months, with stronger results from six to twelve months.

Is it a red flag if an SEO agency guarantees rankings?

Yes. No one can guarantee a specific Google ranking, as Google itself makes clear. Guarantees usually signal either inexperience or risky tactics.

Should I choose a local SEO agency?

A local agency can be valuable if you want face-to-face meetings or local market knowledge, but results and transparency matter most. Many agencies, including SERPentity, work with clients across the UK remotely or in person.

How long should an SEO contract be?

Many agencies ask for an initial commitment of three to six months, because SEO needs time to deliver results. Be cautious of contracts of twelve months or more with no break clause, and make sure you understand the notice period before signing.

How to Choose an SEO Agency: 12 Questions to Ask

Choosing an SEO agency is one of the most important marketing decisions a business can make. Get it right and you'll have a steady stream of customers finding you on Google for years. Get it wrong and you could waste months of budget, or even damage your website's rankings.

I've spoken to plenty of business owners who were burned by a previous agency. In almost every case, asking a few simple questions upfront would have saved them. This guide covers the 12 questions I'd ask if I were hiring an SEO agency, plus the red flags that should send you running. If you want to know more about what we do first, see our SEO services.

Why Choosing the Right SEO Agency Matters

SEO results take months to build, so a poor choice isn't just wasted money. It's also wasted time you can't get back. Worse, some agencies use shortcuts, such as buying spammy links, that can lead to Google penalties that take months to recover from.

The right agency, on the other hand, becomes an extension of your business. They understand your customers, make your website work harder and can point to real results.

12 Questions to Ask an SEO Agency

1. Can you show me results for businesses like mine?

Ask for case studies, ideally in your industry or with a similar business model. Look for concrete outcomes such as more traffic, better rankings and more enquiries, not vague claims.

2. Can I speak to or read reviews from current clients?

Genuine Google reviews from named businesses are hard to fake. Check them yourself rather than relying on testimonials on the agency's own site.

3. What will you actually do each month?

A good agency can explain its work in plain English: technical fixes, content, local SEO, link building. If the answer is vague, the work probably is too.

4. How do you build links?

This question sorts the good from the risky. You want to hear about earning links through content, PR, partnerships and relevant directories, not buying them in bulk. Our guide to link building explains what good looks like.

5. Do you start with an audit?

Any agency proposing a plan without first reviewing your site is guessing. An SEO audit should be the starting point.

6. How will you measure success?

Rankings matter, but they're a means to an end. The best agencies track leads, calls and sales from organic search.

7. What will your reports look like, and how often?

Ask to see an example report. It should be clear, regular and focused on business outcomes.

8. Who will actually work on my account?

In some large agencies, you're sold by a senior person then handed to a junior. Find out who'll be doing the work and whether you can speak to them directly.

9. What's the minimum contract length?

SEO needs time, so a sensible minimum is reasonable. Be wary, though, of long lock-ins with no way out if results don't materialise.

10. How long before I see results?

An honest answer is "early signs in a few months, stronger results from six to twelve months", depending on competition. Anyone promising page one in two weeks for a competitive term is overselling.

11. Who owns the work if we part ways?

Your content, website changes and Google Business Profile should belong to you, not the agency.

12. How do you keep up with Google updates and AI search?

Search is changing fast, with AI overviews and AI assistants now shaping what people see. Your agency should be able to explain how they're adapting.

SEO Agency Red Flags

Walk away if you hear any of these: guaranteed number one rankings, "secret" techniques, hundreds of backlinks for a low fixed price, no access to your own data, or pressure to sign today.

Google itself states that no one can guarantee a number one ranking. An agency that promises it is either misinformed or misleading you.

Other warning signs include:

They can't explain their work without jargon
They don't ask questions about your business, customers or goals
They show no genuine, verifiable reviews
They focus entirely on rankings and never mention leads or revenue
Prices seem too good to be true (see our guide to SEO costs)

What to Expect in the First 90 Days

Knowing what normal looks like helps you judge whether an agency is on track.

Month one: audit and foundations. The agency reviews your site, researches keywords and competitors, and fixes urgent technical issues. You should receive a clear plan.

Month two: on-page and content. Key service pages are improved, new pages are created where there are gaps, and local SEO work begins if relevant.

Month three: authority and momentum. Link building and content continue, and you should start to see early movement in rankings and impressions.

Bigger results usually build from month four onwards, but you should never be left wondering what's being done.

How SERPentity Answers These Questions

I'm happy to be judged by the same questions I've just given you.

Our results are public. Every case study on our site comes from a real client with a real Google review. Clients like Adapt Planning saw major gains in traffic and rankings within weeks, and we've looked after The Stair Guys' SEO for over a year.

We always start with an audit, we explain our work in plain English, and we measure success by enquiries and sales. You'll work directly with me and my team, and we build links the right way. We work across the UK, remotely or in person.

Comparing SEO Proposals Side by Side

Once you've shortlisted two or three agencies, you'll usually receive proposals that look very different. Here's how to compare them fairly.

Compare the work, not just the price. A £600-a-month proposal that includes content, local SEO and link building may be far better value than a £400 one that only covers "optimisation".

Look for specifics. A strong proposal names the pages it will improve, the keywords it will target and the technical issues it has already spotted. A generic proposal suggests the agency hasn't looked at your site properly.

Check the reporting. Does the proposal say how often you'll hear from them and what you'll see? Monthly reports focused on enquiries, traffic and rankings are a good sign.

Consider the fit. You'll be working with this team for months. Choose people who listen, explain things clearly and understand your business.

Trust your instincts. If an agency pressures you to sign quickly, dodges questions or makes promises that sound too good to be true, that tells you something.

Should You Choose a Specialist or a Full-Service Agency?

Some agencies only do SEO. Others also offer web design, PPC and social media. Neither is automatically better, but the right fit depends on what you need.

If your website is slow, dated or difficult to update, an agency that handles both web design and SEO can fix the foundations and grow your rankings without passing you between different suppliers. If you also run Google Ads, having SEO and PPC under one roof means the two channels share data and don't compete for the same budget.

At SERPentity, we offer web design, SEO and PPC, so clients get one joined-up strategy with one point of contact. The most important thing, though, is that the agency is genuinely strong in the area you need most.

Final Thoughts

The right SEO agency will welcome tough questions, because they have good answers. Take your time, check reviews and case studies, and choose a partner who talks about your business goals rather than just rankings.
