Picking an SEO agency is one of those decisions that feels simple until you’re actually in it. You get three proposals, they all say roughly the same things, and you’ve got no real way to know who’s actually good until you’re six months and a decent chunk of budget in.
We wanted to put together something honest. Not a sales pitch for why you should pick us, just a straight guide for how to pick anyone properly.
Why picking an SEO agency can be hard
A few reasons this is genuinely tricky, not just a case of doing your homework:
- There are a lot of options, and most of them look the same on paper.
- The good ones have good sales teams, and a good pitch doesn’t always mean good delivery.
- The technical side can be hard to understand, so it’s easy to nod along without really knowing what you’re agreeing to.
- Results take 3 to 6 months to show up. If you pick wrong, you won’t know for a while, and that’s a long time to be paying for nothing.
Pro tips on picking an SEO agency
These apply to most agency hires, not just SEO.
1. Avoid lock-in contracts like the plague
Any lock-in contract longer than three months is going to cause you issues. If an agency is confident in their work, they shouldn’t need to trap you to keep you.
2. Interview at least three agencies
Don’t just go with the first one that pitches well. Get a few conversations in so you’ve got something to compare against.
3. Meet the person actually working on your account
Not just the salesperson. The person doing the strategy and the work day to day is who you actually need to trust.
Before you do SEO: ask yourself if SEO is for you
SEO isn’t the right move for every business at every stage. Worth asking yourself first:
- What are the actual search terms you want to rank for?
- How long has your business been around?
- What’s your average order value, and how many sales do you actually need to make this worthwhile?
- How big are the competitors in your space?
- Do you have the patience for SEO? If your business needs sales now, be honest with yourself — paid ads might be the better call first.
- Do you have an internal team who can actually manage an agency, or will things fall through the cracks?
Specialist SEO agency vs full service agency
One more decision before you get into the checklist: do you go with a specialist SEO agency, or a full service agency that does SEO alongside paid, social, design and everything else?
Specialist SEO agency
Pros:
- SEO is the whole business, not an add-on service, so it tends to get more depth and focus.
- Usually more technical expertise, since that’s all they do all day.
- Easier to judge them purely on SEO results, no muddying the water with other channels.
Cons:
- You may need a separate agency (or in-house team) for paid ads, social, design and everything else.
- More vendors to manage and more relationships to keep track of.
- Less “one throat to choke” — if something isn’t working, you need to figure out which piece is the problem.
Full service agency
Pros:
- Everything sits under one roof, so channels can (in theory) work together instead of in silos.
- One point of contact for your whole marketing spend.
- Can be simpler to manage if you don’t have a big internal team.
Cons:
- SEO is often the smaller, less prioritised part of the business.
- The person on your SEO account may not be a specialist — they might be spread across multiple channels.
- Harder to tell if SEO specifically is working, since reporting often gets blended across channels.
Neither is automatically the right answer. If SEO is a core growth channel for your business, a specialist usually makes sense. If you need everything running together and don’t have the internal capacity to manage multiple vendors, full service can work — just go in with eyes open about how much SEO depth you’re actually getting.
Hiring an SEO agency checklist
| Question | Why it matters |
|---|---|
| Have you reviewed multiple agencies? | Gives you something to compare against instead of just trusting the first pitch |
| Have you met the person doing the work, or just the salesperson? | The salesperson isn't who'll be in your account every week |
| How many accounts does that person manage? | Too many and you're getting scraps of attention |
| Is there no lock-in contract? | If they're confident, they won't need to trap you |
| Do they have case studies from your industry? | Shows they understand your specific market, not just SEO in general |
| If not, have they broken down a competitor's rankings for you? | A good sign they've actually looked at your space, not just recycled a pitch |
| Is the strategy easy to understand? | If you can't follow it, you won't be able to tell if it's working |
| Do they mention how to actually rank in AI Overviews? | If they're not talking about this in 2026, they're behind |
| Do they talk about Google Shopping? (ecommerce only) | A big miss if you're ecommerce and this isn't part of the plan |
| Do they ask about your sales process? | Shows they care about leads and revenue, not just traffic |
| Do they talk about ROI, or just rankings? | Rankings don't pay the bills, revenue does |
| Do they implement, or just consult? | Consulting only means you need someone else to actually do the work |
| Is any of the work outsourced, and how much? | Not a dealbreaker, but you should know |
| What do they actually report on? | Vague reporting usually means vague results |
| What are the key metrics for success? | If they can't define this upfront, how will you know if it's working? |
| How do they get backlinks? | Some methods can get your site penalised, worth understanding |
| Have they worked with your specific CMS before? | Saves you the learning curve costing you time and money |
Red flags
- Guaranteed rankings — nobody can guarantee this, full stop.
- “You’ll get 10+ keywords a month” style promises.
- Long lock-in contracts with no exit clause.
- Pricing dramatically cheaper than market rate for your industry.
- Cagey or defensive when you ask direct questions about strategy.
Green flags
- They’re upfront about timelines and don’t promise fast results.
- They show you real case studies with actual numbers, not just vague claims.
- They talk about ROI and revenue, not just rankings and traffic.
- They’re happy to introduce you to the person actually working on your account.
- They ask detailed questions about your business before pitching a strategy.
- They’re transparent about what’s included and what’s outsourced.
- They have no issue with a short contract term.
- They talk about outcomes, not outputs — so it’s “targeting these three keywords because they map to your highest margin product” instead of “we’ll publish eight blog posts this month.”
- They show you real results with context, not just one good number, and they can explain why a specific strategy worked for that client’s market.
- They’re honest about timelines, including that a penalised site or a competitive industry can take 6 to 12 months before you see real movement.
- They connect SEO with your other marketing, like using paid ads data to find keywords worth targeting organically and using SEO content to bring your cost per click down over time.
- They give you a clear monthly report that actually explains what changed, what was published, what links came in, and what it means for traffic and conversions — not just a dashboard you’re left to interpret yourself.
Questions to ask during an audit
- Who specifically will be working on my account, and what’s their experience level? Get names and backgrounds, not just “our team.”
- What does month one actually look like? Get them to walk you through the work week by week.
- What does success look like at 3, 6 and 12 months, and how will we actually measure it?
- Can you show me link building work you’ve done for other clients? What sites did the links come from, and how did you get them?
- What happens to my content and links if I leave? The answer should always be that you own everything. If it’s not, walk away.
- What’s your process when rankings drop or something unexpected happens? This is the question that tells you how they handle a bad month, not just a good one.
- Have you worked in my industry before, and what were the results? Industry experience isn’t mandatory, but their answer tells you how much they’ve actually thought about your competitive landscape.
- What are the biggest technical issues you’ve found, and how are they impacting rankings?
- Which pages are already close to ranking well, and what’s holding them back?
- What’s the content gap between us and our top competitors?
- Are there any quick wins you’d tackle in month one?
- How is the site performing for AI Overviews and answer engines right now?
- What would you prioritise first, and why?
If an agency can’t answer these clearly and specifically to your business, that’s your answer.
