Every SEO company will tell you they get results. They all have case studies, they all sound confident on the call, and none of them will say the honest thing, which is that you cannot verify most of what they just told you. That is the actual problem with choosing one.
So stop trying to work out who is best and start working out who can explain themselves. The seven questions below are the ones where a real practitioner and a salesperson give visibly different answers, and each one comes with what a good answer sounds like so you can tell which you are getting.
How to Choose an SEO Company at a Glance
- Can you show me work for a business like mine?
- What will you actually deliver each month?
- How will we measure this, and whose accounts does the data live in?
- Who is doing the work?
- Where do your links come from?
- What access do you need, and at what level?
- What happens if I want to leave?
Judge the answers, not the deck. Anyone who cannot answer these in plain language either does not know or does not want you to.

Decide What You Actually Need First
Most bad hires start before the shortlist, because the buyer has not decided what problem they are solving. “We need SEO” is not a brief, and it means every provider gets to define the job as whatever they happen to sell.
Narrow it down before you talk to anyone. A local service business that wants the phone to ring needs Google Business Profile work, location pages and reviews. An ecommerce site with 4,000 products has a technical and site-structure problem. A B2B company with no content needs a content operation. These are genuinely different skill sets, and the agency that is excellent at one is often mediocre at another.
Google’s own position on this is worth hearing, since it has no commercial interest in you hiring anyone: its guidance says that if you run a small local business you can probably do much of this work yourself, and recommends starting with its SEO starter guide before hiring. Reading it also means you will recognise it if someone later proposes something Google explicitly discourages.
Then decide what would make this a success. More qualified enquiries, more revenue from organic, ranking for a specific set of commercial terms. Write it down before the first call, because if you do not define success, the provider will define it for you, and they will pick something easy.
The Seven Questions That Actually Matter
1. Can You Show Me Work for a Business Like Mine?
Not a case study PDF. A live URL you can open, in a similar market, at a similar scale. Then ask what the site looked like when they took it on and what specifically they changed.
Good answerNames the client or explains why it cannot, describes the starting problem, the work done, and the outcome, and volunteers the parts that did not work.
Worry ifEvery example is anonymous, every result is a percentage with no baseline, or the case studies are all from years ago.
“Traffic up 400 percent” means nothing without the starting number. Four visits to twenty visits is 400 percent. Ask for absolute figures, and ask whether the increase was in traffic or in enquiries, because those come apart more often than anyone admits.
2. What Will You Actually Deliver Each Month?
This is the question that prevents most disputes, and it is the one buyers skip because it feels rude. It is not rude. You are buying a service and you are entitled to know what arrives.
Good answerQuantities and units. Four articles at a stated length, technical fixes as prioritised tickets, two link placements, one strategy call. Plus what is excluded.
Worry ifThe answer is a list of categories: “ongoing optimisation, content, link building, reporting.” That describes SEO in general, not what you are paying for.
Push specifically on implementation. Plenty of engagements deliver a document of recommendations and stop, and the client discovers they now need a developer nobody budgeted for. Ask directly: do you make the changes on my site, or do you tell me what to change?
3. How Will We Measure This, and Whose Accounts Does the Data Live In?
The second half of that question matters more than the first. If reporting comes out of the agency’s own tools rather than accounts you own, you lose your entire performance history on the day you leave, and you have no way to check anything they tell you in the meantime.
Good answerData comes from your Google Search Console and Analytics, which you own. Metrics agreed up front, tied to enquiries or revenue where those are trackable, not rankings alone.
Worry ifReporting is a branded dashboard you cannot trace back to a source, or the headline metric is a ranking count on a keyword list they chose.
Rankings alone are the oldest trick in the industry. It is trivial to show steady improvement on twenty phrases nobody searches for. If rankings are being reported, insist the keyword list is agreed in writing at the start so it cannot quietly drift toward easier terms in month four.
4. Who Is Doing the Work?
The person selling is frequently not the person delivering. That is not automatically a problem, but you should know before you sign rather than discovering it when the first report arrives from someone you have never met.
Good answerNames the people, explains who handles technical, content and links, and is upfront about which parts are subcontracted and to whom.
Worry ifYou get a vague “our team” and no names, or the answer changes between the sales call and the kickoff.
Ask how communication will work, who you contact, and how often. Google’s own hiring guidance lists exactly this among the questions to ask, alongside whether the SEO will share every change they make to your site and explain the reasoning. Both are reasonable to expect and easy to answer if the answer is honest.
5. Where Do Your Links Come From?
Ask it plainly, and watch what happens. This is the single most revealing question in the list, because link acquisition is where the risk lives and where the vagueness usually starts.
Good answerExplains the method (outreach, digital PR, guest placements, citations), how sites are vetted, roughly what a placement costs, and whether any are recurring-fee rather than permanent.
Worry ifThey will not describe the method, cite proprietary networks, quote a volume of links per month as the main selling point, or ask you to link back to them.
That last one is worth knowing about: Google’s guidance states plainly that you should never have to link to an SEO, and warns off anyone talking about link popularity schemes or submitting your site to thousands of search engines. Also ask whether placements are paid monthly. If they are, your rankings are on a subscription and they unwind when you stop.
The reason this question matters more than the others is liability. Google is explicit that you are ultimately responsible for the actions of anyone you hire, and that content created deceptively on your behalf can get your site removed from the index. Not their site. Yours. Ask for a written commitment that all work complies with Google’s spam policies.
6. What Access Do You Need, and at What Level?
A good provider has a specific answer and asks for the minimum. A careless one asks for everything on day one.
Good answerLists each system and the level needed, and is comfortable starting with read-only where read-only is enough.
Worry ifThey want admin on everything before any work is scoped, or cannot explain why they need a particular level of access.
Google’s guidance is specific here and it is a useful line to hold: for an initial audit, grant read access to Search Console only, not write access. Write access can follow once there is a reason for it. If someone needs server or FTP access, they should be willing to explain every change they make.
Make sure your Search Console, Analytics and Google Business Profile are created under your ownership with the provider added as a user, never the reverse. Getting this wrong is how businesses end up locked out of their own data by a former contractor.
7. What Happens If I Want to Leave?
Ask this on the first call, before anyone has invested anything in the relationship. The answer tells you how the whole engagement is structured.
Good answerA clear notice period, no penalty for leaving, everything produced transfers to you, and access is handed back and revoked at a defined point.
Worry ifLong lock-in with no exit clause, auto-renewal you have to remember to cancel, or content that is licensed to you rather than owned by you.
Long initial terms are not automatically a red flag, since results compound and nobody serious wants to be judged on week three. What matters is the notice period and whether you can leave if deliverables are missed. The detail on all of this sits in the paperwork, and it is worth knowing what should be in an SEO contract before you get to that stage.
Red Flags That Should End the Call
- Guaranteed rankings. Google’s documentation states that no one can guarantee a number one ranking, and warns against anyone who claims otherwise, alleges a special relationship with Google, or advertises priority submission.
- They contacted you out of the blue. Google’s guidance says to treat unsolicited SEO email with the same scepticism as any other spam. It gets those emails too.
- Secrecy about method. Being unwilling to explain what they intend to do is not protecting a trade secret, it is avoiding a question.
- Volume as the pitch. Hundreds of links, hundreds of directory submissions, thousands of pages. Volume is the easiest thing to sell and the easiest thing to fake.
- A single-tool audit as the diagnosis. Google notes that it does not evaluate or endorse third-party SEO tools, and that those tools have no access to its internal ranking data. Be wary of anything claiming to be Google-approved.
- Pressure and deadlines. A discount that expires on Friday is a sales tactic, not a business case.
- No questions about your business. If they have not asked who your customers are, who you compete with, or how enquiries currently arrive, they are selling a package rather than solving your problem.
None of these are proof of dishonesty on their own. Any two of them together, and I would walk.
How to Check What They Told You
Everything above is answers. This part is verification, and almost nobody does it.
Call two references and ask better questions. Not “were you happy,” which gets you a polite yes. Ask what the reporting was like, whether deliverables arrived on time, what the provider did when something went wrong, and whether they would hire them again for the same work.
Ask for a small paid piece of work first. An audit, or a defined technical project. You learn more from one real deliverable than from three sales calls, and it costs less than three months of a retainer you regret.
Check the recommendations against Google’s own documentation. This is Google’s explicit advice: think critically about claims, check them against official guidance, and ask whether the provider cites that guidance as supporting evidence. Its page on third-party SEO tools and advice exists precisely because so much circulating advice is not grounded in anything.
One piece of common advice I would push back on: “check whether they rank for SEO keywords themselves.” It sounds sensible and it is nearly useless. Terms like “seo company” are brutally competitive, and plenty of excellent practitioners are too busy doing client work to rank their own site, while some of the worst offenders rank well because self-promotion is the only thing they are good at. Judge the client work, not the shoemaker’s shoes.
Frequently Asked Questions
How many SEO companies should I talk to?
Three is enough. Fewer and you have no comparison, more and every conversation blurs into the last one. Ask all three the same seven questions and the differences in the answers will be obvious, which is the entire point of asking the same questions.
What questions should I ask an SEO agency?
The seven above cover the ground: proof of similar work, specific monthly deliverables, measurement and data ownership, who does the work, where links come from, what access they need, and how you exit. Google’s own guidance adds two more worth using: what results do you expect and in what timeframe, and will you share every change you make to my site.
Should I choose an agency or a freelancer?
It depends on what you need rather than which is better. An agency gives you breadth and cover when someone is on holiday. A freelancer gives you the person who does the work, usually cheaper and usually faster to reach, with a real limit on how much they can take on. If your problem spans technical, content and links at scale, that is an agency job. If it is focused, a good individual will often go deeper on it.
How do I know if an SEO company is legitimate?
They explain their method in plain language, show live work you can verify, ask questions about your business before proposing anything, work in accounts you own, guarantee effort rather than positions, and let you leave. Legitimacy shows up in how someone answers questions, not in credentials or awards.
What if the SEO company damages my site?
This is the risk buyers most consistently underestimate. Google is clear that you carry responsibility for what a provider does on your behalf, and that deceptive work can result in your site being removed from search results. Reduce the exposure up front: limit access, get compliance with Google’s guidelines written into the agreement, and keep ownership of your own accounts so you can see what changed.
Can I report an SEO company that deceived me?
In the United States, Google’s guidance points to the Federal Trade Commission for deceptive or unfair business practices, via the FTC website. For complaints against a company based outside the United States, it directs people to econsumer.gov. Keep your reports, change logs and written scope throughout the engagement, because a dispute you cannot document is a dispute you lose.
Making the Call
Choose the provider who was most specific, not the one who was most confident. Specificity is the only signal in that whole process that is genuinely hard to fake: vague answers are free, and precise ones require actually knowing what you are going to do.
If two candidates are close, pick the one who told you something you did not want to hear. Someone willing to say your timeline is unrealistic or your budget will not cover the market you are targeting is someone who will still be honest with you in month six, when it matters more.
For what it is worth, this is how I prefer to be evaluated. I am a freelance SEO consultant rather than an agency, so the person on the call is the person doing the work, and my case studies are live sites with real starting numbers rather than percentages without baselines. If you want to run the seven questions past me, get in touch and I will answer them straight, including the parts that are not flattering.
