How to Choose an SEO Agency (and Check Their Claims Yourself)

Choose an SEO agency on evidence you can check, not on the pitch. Ask who will actually change your site, whether you will own every account, what the agency refuses to do, and whether reports lead with enquiries rather than rankings. Treat promised positions or secrecy about links as reasons to walk away.

How do you choose an SEO agency?

Choose an SEO agency by testing claims you can verify: who will do the work, what they will change on your site, whether you will own every account, what they refuse to do, and whether reports lead with enquiries instead of rankings. A confident pitch proves little. Access, scope and named people prove far more.

There is no UK licence or qualification for SEO, so nothing external vouches for an agency. That is how people who have been let down once get let down twice: the checks they relied on, a polished case study or a friendly sales call, are the parts the agency fully controls. The checks below move to things you can open yourself.

They are written to work on any shortlist, ours included. If a competitor answers them better than we do, hire the competitor. And if you are not yet sure search is worth paying for at all, start with whether you need an SEO agency, then come back here. For what a full engagement should contain, an SEO service in outline is a fair yardstick.

The point
For what a full engagement should contain, an SEO service in outline is a fair yardstick.

What should you settle before you speak to any agency?

Settle four things first: what one enquiry is worth to you, what search already brings you, who inside the business will own the work, and whether your site can be changed. Without them every proposal sounds plausible, because you have nothing to hold it against.

A rough value per enquiry lets you test any proposal against arithmetic, and it is the number that decides whether search or paid clicks suits you in the first place. It does not need to be precise. It needs to exist before the first meeting.

Open your Search Console and analytics, if they exist, and write down what they show today. An agency's later claims can only be checked against a baseline you recorded before it arrived. If tracking is missing or broken, say so: repairing it is a legitimate first job, and an agency that does not mention it is skipping the step that makes everything else measurable. Also work out who can make changes to the site. Traffic that lands on pages that cannot convert is wasted, which is why turning existing visitors into enquiries is often the better first spend.

The point
Open your Search Console and analytics, if they exist, and write down what they show today.

Which kind of SEO help suits your situation?

An agency suits ongoing work that needs several skills and someone to carry it out. A consultant suits advice when you or your developer will do the work. A freelancer suits a defined job. An in-house hire suits continuous work. Most disappointments come from buying the wrong shape of help, not from picking the wrong supplier.

Option	Choose it when	Where it goes wrong	One question to ask
SEO agency	The work needs technical fixes, writing, authority building and measurement together, and somebody must implement it.	Hand-offs between salesperson, account manager and specialist, so nobody owns the result.	Who, by name, will change my site?
SEO consultant	You want judgement on what to do and in what order, and you or your developer can carry it out.	A good plan with nobody to execute it. Advice that is never implemented is the commonest failure.	Who implements this, and what if my developer cannot?
Freelancer	One defined job with a clear end, such as a set of pages or a technical clean-up.	One person's range and availability. If they move on, so does the knowledge.	Are all accounts and files in my name?
In-house hire	There is enough continuous work to keep one person busy, and a manager who can direct them. The wider trade-offs are in freelancer, agency or in-house.	One person rarely covers technical, content and authority work equally well.	What happens when this person leaves?
One-off diagnosis	You want to know what is wrong before committing to a retainer, or you hold an old report nobody acted on. An SEO audit is that shape.	A tool export dressed up as a diagnosis, with hundreds of warnings at equal weight.	What would you fix first, and why?

What should you check before you shortlist an agency?

Check five things before asking anyone for a proposal: who the named people are, whether you can visit work they did, whether their claims carry a baseline, how their own site reads, and whether a past client will talk to you. Each takes minutes, and together they filter out most weak pitches.

Named people. Find out who diagnoses, who writes and who changes the site. A pitch from one person and delivery by another is common, and you are entitled to know. Here the people are named on the about page, and you should expect the same from anyone on your shortlist.
Live work you can visit. Ask for pages the agency built or improved that you can open today, then read them as a customer would. Thin pages with only a town name swapped, or text that could belong to any business, show how your own pages will look.
Claims with a baseline. A case study that says traffic grew, without saying from what, over which period and in absolute numbers, is an assertion rather than evidence. Ask for the starting point and for what the client actually measured, which should be enquiries, not visits.
Their own website. If the agency's pages are thin, slow or hard to read, ask how that squares with their advice. Do not treat their ranking for a competitive phrase as proof in either direction: ranking reflects resources and age as much as skill.
One past client who will talk. Ask what went wrong on their project and how it was handled. Every agency has a project that went badly. How they behaved when it did is the information you are after.

What questions should you ask an SEO agency?

Ask what happens in the first month, who changes the site, how links are built, what you own, what the agency refuses to do and how it will tell you when something is not working. Take these to any agency, ours included. A vague answer is itself an answer.

What will you do in the first month, and who makes each change? Listen for specific, unglamorous work, such as indexing, titles, internal links and repaired tracking, with a name against each item. Talk of research and strategy often means a document.
Will I have administrator access to my own Search Console, Analytics and Google Business Profile from day one? The answer should be yes. If you cannot open the data yourself, you are reading claims rather than a report.
How do you build authority, and where do the links come from? Good answers mention citations, directories, trade bodies, chambers and real stories. Reluctance to name sources, or links sold by the dozen, points to schemes that risk a manual action.
Who writes the content, and who checks that they understand my trade? Ask to see something written for a client in a field unfamiliar to the writer. If every sample sounds alike, assume the text was generated and lightly tidied.
What will you refuse to do? Real examples are the sign of standards: no bought links, no doorway pages for towns nobody serves, no promise of a position nobody controls. An agency with no refusals has no line.
What do you need from my side? If the site cannot be edited, or fixes need a developer you do not have, say so now. A rebuild or new platform may need to come before any search work pays back.
How will you tell me when it is not working? A good answer names the measure and the moment: which number must move, against what baseline, and what changes if it does not. Constant encouraging progress is not reporting.
What do I keep if I leave? You should keep pages, content, profiles and tracking, because they were built in your accounts and on your domain, with no buyout fee and nothing licensed back.
What does a technical audit from you actually find, and can I see an anonymised sample? Compare it with what a proper SEO audit includes: findings ranked by likely effect on enquiries, with evidence you can check.
Would you tell me if search is the wrong channel for me? The best answer sometimes argues against a retainer. If the response is only enthusiasm, you are talking to sales.

What do common agency claims actually tell you?

Some claims are patterns worth testing, not proof of anything. The table pairs each with what it can conceal and how to check it yourself. None means an agency is dishonest; each means you should ask one more question before you believe it.

Claim you may hear	What it can conceal	How to check it
We will get you to position one	Nobody controls Google's results. A promise like this can mean terms with no competition, or that you will not check.	Ask for the exact search phrases, then look at who ranks for them now.
We use a proprietary method	Either very little, or something outside Google's guidelines.	Ask them to explain in plain English what changes on your site and why.
We build hundreds of quality links a month	Links sold by number are the pattern behind manual actions.	Ask for three example sites and why each would link to a business like yours.
Our dashboard shows everything live	A view inside the agency's own account that disappears when you leave.	Ask to see the same figures in your own Search Console and Analytics.
We do AI SEO and optimise for ChatGPT	Ordinary SEO relabelled, or a promise nobody can keep, since nobody controls AI answers.	Ask what specifically changes on the page, then compare with what AI search optimisation involves.
Our scan found hundreds of errors on your site	A tool export sent to a stranger. The count measures the tool, not your problem.	Ask which three issues would change enquiries, and why those three.

Which warning signs mean you should walk away?

Walk away from promised rankings, secrecy about methods or link sources, accounts held in the agency's name, contracts that lock in your content, and reports that lead with positions. One sign deserves a direct question. Two or more is a reason to leave the conversation, however good the presentation was.

A promised position or date. Nobody controls the results page, so a pledge of position one by a given day is aimed either at terms with no competition or at you not checking.
Secrecy. A method that cannot be explained in plain English usually hides very little, or something against the guidelines.
Accounts in the agency's name. Search Console, Analytics and your Google Business Profile belong to you. If you cannot administer them, you cannot leave without losing history.
A contract that traps your work. Notice periods are normal. Licensing your own pages back to you, or taking content with them on exit, is not.
Reports that open with rankings. Forty phrases in the top ten means little if the phone has not rung. The first line should be enquiries, calls and form submissions.
A price far below the rest with no explanation. Ask which work is not being done. The shape of the cost is explained in what SEO costs per month in the UK.
Pressure to sign this week. A good supplier can wait while you check the references you asked for.

How do you check an agency's claims yourself?

Check claims against sources you control. Open Search Console for impressions and clicks, analytics for enquiries, and the live page for what changed. If a report says something improved, find the same figure in your own account. When you cannot, ask why before paying the next invoice.

For technical claims, ask for the specific change and confirm it on the live site: a canonical tag, a redirect, a page that now loads its content without JavaScript. Findings from technical SEO work should be things you can point at, not adjectives.

For content claims, read what was published as a customer would. For link claims, ask for the pages where the links sit. For local claims, search from your own area and inspect the profile in your own Google account, because local search work rises or falls with a profile you control.

The point
For local claims, search from your own area and inspect the profile in your own Google account, because local search work rises or falls with a profile you control.

What should the contract and the accounts say?

You should own every account and asset from day one: Search Console, analytics, Google Business Profile, domain, hosting and the content itself. The contract should describe work rather than outcomes, state the notice period plainly, and say that nothing is licensed back to you or withheld when you leave.

Scope written as verbs is checkable: technical fixes implemented, pages written, profile maintained, report delivered. Scope written as outcomes is not, because no agency controls the results page. If the document promises a position, you are being sold something other than the work.

A notice period is normal. A long minimum term before anything is delivered, or a fee to leave, is worth negotiating before you sign, not discovering afterwards.

The point
A long minimum term before anything is delivered, or a fee to leave, is worth negotiating before you sign, not discovering afterwards.

When should you not hire an SEO agency yet?

Do not hire one when almost nobody searches for what you sell, when your site cannot yet turn a visit into an enquiry, when you need leads this month, or when a rebuild is coming. In each case the money is better spent elsewhere first, and an honest agency will tell you so.

If demand is thin or unproven, test it before committing: a fuller test of whether search is worth paying for sets out how. If you need enquiries quickly, paid advertising is the faster tool, and organic work can follow.

If a redesign or replatform is on the horizon, settle that first, then plan the move so that pages already earning traffic survive it. Paying for months of optimisation on a site you are about to replace is the avoidable mistake.

The point
If a redesign or replatform is on the horizon, settle that first, then plan the move so that pages already earning traffic survive it.

Does it matter where an SEO agency is based?

For the work itself, rarely: audits, fixes, content and review calls run remotely. It matters for confidence if you want to meet in person, and for local knowledge only where the work depends on it. Judge an agency by what it can show you, not by the address on its website.

Prabhu Solutions is registered at 14 Chester Rise, Oldbury, B68 0SS, in the West Midlands, and works with businesses remotely. Our delivery record to date is international rather than UK-based, and we would rather say so than let a postcode suggest otherwise. For the regional picture, see how this applies across the West Midlands.

To put these questions to us, tell us about your site and what you need. If another agency answers them better, hire that one.

Questions people ask about this

How much should I expect to pay for an SEO agency?

Judge scope rather than the number. Ask what is included each month: technical fixes, content, locations or categories covered, authority building and reporting. Two quotes far apart usually describe different work. The drivers behind monthly SEO cost are worth knowing, and a quote given before anyone has looked at your site is a guess.

How do I know if an SEO agency is reliable?

A reliable agency is one you can check. It names the people who will do the work, gives you administrator access to your own accounts, describes methods in plain English, reports enquiries before rankings, and says what it will not do. If any of those is missing, ask why before signing anything.

Should I choose a local SEO agency or one elsewhere in the UK?

Choose on evidence, not postcode. The work runs remotely either way. Location helps if you want to meet, or if the work needs real local knowledge, such as a Google Business Profile for a single-site business. Ask any agency who actually touches your site, wherever it is based.

Can an SEO agency promise me page one?

No. Nobody controls Google's results, so an agency promising a position is either aiming at phrases with no competition or relying on you not checking. Ask instead what they will change, which measure should move first, and how you will see it in your own accounts.

What should I do if my last SEO agency left a mess?

Regain control first: Search Console, analytics, Google Business Profile, domain and hosting should all be in your name. Then get an independent view of what was changed and what was not, such as a written audit ranked by impact. Decide what to do next only after that.

How many agencies should I speak to?

Two or three is enough. Give each the same written brief, ask each the same questions, and compare the answers rather than the presentations. The method is the same for ads and social, as in choosing a digital marketing agency.

Do I need an agency, or would a consultant do?

If you or your developer can carry out the work, a consultant's judgement may be enough. If the fixes, writing and measurement all need doing, an agency fits better. What an SEO consultant does and does not do is worth reading before you decide.
