Picking an SEO company used to be pretty straightforward.
You’d Google “best SEO agency,” skim a few case studies, maybe ask about keyword research, and hope they could push your site higher in Google search.
Now it’s messier.
Because SEO is no longer just about showing up in a search result. It’s about showing up in AI answers, getting pulled into AI Overview summaries, and being mentioned in the exact articles AI tools trust when they recommend products.
So when someone asks me how to choose the right SEO company today, I always say the same thing:
You’re not hiring someone to “do SEO.” You’re hiring someone to get you visibility everywhere people search, including search engines and AI platforms.
And if the agency doesn’t understand that shift, they’ll probably deliver outdated SEO practices that look good in reports but don’t move the needle in real life.
In this article, I’ll break down what separates a good SEO company from a generic SEO service provider, what red flags to avoid, and how to choose the right SEO company if your goal is organic traffic growth and AI visibility at the same time.
Key Takeaways
- SEO companies in 2026 need to understand both Google search and AI visibility, not just traditional search engine optimization.
- A good SEO agency should cover technical SEO, keyword research, content marketing, and link building as one connected SEO strategy.
- Strong link building is still the deciding factor behind most SEO results, because it influences rankings and AI recommendations.
- The best SEO company will show real case studies, clear reporting (Google Analytics + Search Console), and a measurable SEO campaign plan.
- If an agency guarantees instant results or uses black hat SEO tactics, that’s a red flag, not a shortcut.

Why AI Visibility Changes How You Choose an SEO Company
A couple years ago, hiring an SEO company was mostly about one thing: ranking higher in Google search.
And yes, that still matters. Probably more than ever.
But now there’s an extra layer on top of search engine optimization that people don’t always understand until it’s too late. AI has changed the way search engines present information, and it has changed the way users consume it.
When someone searches for something like:
“best outreach tools”
“top link building platforms”
“email finder alternatives”
They might not even scroll through the search result page anymore. They’ll read the AI Overview, get their answer, and move on.
So the question isn’t just “can this SEO agency get me traffic?”
It’s “can this agency get my brand included in the answers people are seeing?”
Because AI visibility is basically a second SEO battleground.
If your company isn’t being mentioned in the right places online, you don’t just lose rankings. You lose recommendations.
And recommendations are what drive buyers.
AI systems don’t invent your brand out of thin air. They pull from what’s already ranking, what’s already being referenced, and what’s already being discussed across the internet.
Meaning, if your SEO company is still operating like it’s 2016, focusing only on a few keywords and basic on-page tweaks, you’re going to miss a huge chunk of visibility that your competitors will gladly take.
What a Good SEO Company Actually Does
A good SEO company does not just “optimize keywords.”
If that’s their entire pitch, keep looking.
A proper SEO agency should approach search engine optimization as a system. That means technical SEO, keyword research, content marketing, link building, and reporting all working together under one clear SEO strategy.
Here’s what that actually looks like:
First, they handle technical SEO. If your site cannot be crawled properly by a search engine, no amount of content will fix it. Site structure, page speed, indexation, and user experience still matter.
Second, they handle keyword research properly. Not just high-volume vanity terms, but real queries that drive organic traffic and align with your SEO goals.
A good SEO professional should be able to explain why they are targeting certain terms and how those terms connect to revenue.
Third, they build a content strategy that supports your SEO campaign. That means content marketing designed to rank, convert, and support your broader digital marketing efforts.
But here’s the truth most SEO agencies won’t say out loud:
Content alone rarely wins anymore.
Which brings us to the real deciding factor.
Why Link Building is the Deciding Factor in 2026
In 2026, link building is still the leverage point.
Search engines still rely heavily on backlinks as a ranking factor. If two companies publish equally good content, the one with stronger backlinks wins the search result more often than not.
And now links serve a second purpose.
When AI tools generate answers, they often pull from comparison pages, high-authority articles and listicles like these:
If your brand appears consistently in those places, your chances of being included in AI-generated recommendations increase dramatically.
So link building is no longer just about organic traffic.
It’s about:
- Ranking in Google search
- Getting mentioned in AI summaries
- Building brand visibility across the web
- Supporting long-term SEO efforts
This is where most potential SEO agencies fall short. They either outsource link building cheaply or avoid it entirely because it is hard.
If you’re serious about choosing the right SEO company, ask them directly how they approach link building. If the answer is vague, that’s your signal.
And if what you really need is high-quality, dual-purpose placements that improve rankings and AI visibility at the same time, that’s exactly what our done-for-you link building is built for.
We focus on getting you featured in real, high-traffic listicles and industry publications that move the needle.
Not spammy directories. Not black hat SEO tricks. Just quality SEO backed by strategic placements that compound over time.
Red Flags to Watch Out For
Not every SEO company is built the same.
And the annoying part is that on the surface, they all sound identical. Every SEO agency claims they use “proven strategies,” every agency says they do “full-service SEO,” and somehow everyone is the best SEO company in their niche.
So instead of listening to the sales pitch, I always look for red flags.
Here are the biggest ones.
Guaranteed rankings
If an SEO company guarantees you the #1 spot in Google search, run.
No SEO expert controls the search engine algorithm, and anyone promising guaranteed results is either lying or planning to use risky tactics that won’t hold up.
No real case studies
A good SEO company should be able to show case studies, period.
Not screenshots of a random traffic spike.
Actual case studies showing what they did, what SEO strategy they used, and how organic traffic grew over time. If potential SEO agencies dodge this question, that tells you everything.
“We don’t do link building”
This one is more common than you’d think.
Some agencies avoid link building because it’s difficult, time-consuming, and hard to scale. But pretending backlinks don’t matter in 2026 is like pretending fitness doesn’t require exercise.
If your SEO agency can’t explain how they build links, they’re not serious.
Black hat SEO shortcuts
If you hear terms like PBNs, link farms, bulk backlinks, automated link drops, or “thousands of links per month,” that’s black hat SEO.
It might temporarily move rankings, but it’s not good SEO. It’s gambling with your domain.
You want white hat SEO practices that build real long-term visibility.
Vague reporting and unclear KPIs
If an SEO firm sends you monthly reports full of graphs but can’t explain what they mean, that’s not transparency. That’s distraction.
A right SEO company should clearly show progress in Google Analytics and Google Search Console, and tie everything back to your SEO goals.
No technical SEO foundation
Some agencies jump straight into content marketing without checking whether your site can even rank.
If they don’t mention technical SEO, site audits, indexation, or user experience, that’s a red flag. SEO efforts stacked on top of a broken foundation rarely work.
Local SEO Agency vs National SEO Agency
Not every business needs the same kind of SEO agency.
If you run a plumbing company in Austin or a dental clinic in Chicago, your SEO needs look very different from a SaaS company selling globally.
That’s where the difference between a local SEO agency and a national SEO agency comes in.
When a Local SEO Agency Makes Sense
A local SEO agency focuses on ranking you for location-based searches.
Think:
- “best dentist near me”
- “plumber in Austin”
- “coffee shop downtown”
Local SEO is heavily tied to Google Business Profile optimization, maps visibility, local citations, and proximity-based ranking factors.
If your business depends on geographic search traffic, hiring a local SEO agency is the logical move. They’ll prioritize map pack rankings, reviews, and location signals over broad national keyword research.
When You Need a National or Global SEO Agency
If you sell software, online services, or ship products globally, local SEO alone won’t cut it.
You need a broader SEO strategy focused on:
- Ranking in national search results
- Growing organic traffic at scale
- Competing in highly competitive industries
- Building authority through link building
A global SEO agency should focus on scalable keyword research, technical SEO, content marketing, and backlinks that improve your visibility across the entire search engine landscape.
The AI Visibility Angle
Here’s where it gets interesting.
Even local SEO now overlaps with AI visibility. AI tools often pull business information from structured listings, reviews, and high-authority sites.
If you’re a local business, appearing consistently across directories and trusted platforms increases your chances of being recommended in AI-generated answers.
For national brands, listicle placements and strong backlinks are even more important. If your brand appears in comparison articles that rank well, AI systems are more likely to reference you.
So the right SEO agency depends on your SEO needs.
If you serve one city, choose a local SEO agency.
If you compete nationally or globally, you need an agency that understands broader organic traffic growth and link building at scale.
Questions to Ask Before Hiring an SEO Agency
Before you sign anything, ask these questions.
Most businesses choose an SEO agency based on a polished pitch or a flashy website. A better approach is to pressure-test their thinking.
The right SEO company should be able to answer these clearly, without hiding behind jargon.
1. What’s Your Actual SEO Strategy?
Not “we do SEO.”
Ask them to explain their SEO strategy step by step. How do they approach technical SEO? How do they prioritize keyword research? How do they measure organic traffic growth?
If they can’t connect tactics to your SEO goals, that’s a problem.
2. How Do You Approach Link Building?
This question alone filters out most average agencies.
Link building is still one of the strongest ranking factors in any search engine. Ask them:
- How do you earn backlinks?
- What kinds of sites do you target?
- Can I see examples of placements?
- How does this support AI visibility?
The right SEO agency should have a clear, ethical approach. If they dodge the question or talk vaguely about “authority building,” dig deeper.
3. Can I See Real Case Studies?
Not testimonials. Case studies.
Ask for examples where they improved organic traffic, moved pages up in a search result, or executed a successful SEO campaign. Good SEO companies should be proud to show their work.
If they can’t provide proof, they’re not the best SEO agency for you.
4. How Do You Report Results?
Do they use Google Analytics? Google Search Console? How often do they report? What metrics do they track?
A serious SEO professional should tie results back to:
- Organic traffic
- Keyword movement
- Conversions
- Revenue impact
If reporting feels vague, that’s a red flag.
5. How Do You Define Success?
Some agencies focus only on rankings. Others focus on traffic. The right SEO company should align with your actual SEO needs.
If your goal is leads, they should structure your SEO efforts differently than if your goal is brand awareness.
You’re not just hiring an agency. You’re choosing a long-term SEO partner.
And the right SEO company will answer these questions confidently, transparently, and with specifics, not buzzwords.

Frequently Asked Questions (FAQ)
How do I choose the right SEO company?
Start by looking for proof, not promises. The right SEO company should show real case studies, explain their SEO strategy clearly, and be transparent about what drives organic traffic growth.
What’s the difference between an SEO company and an SEO agency?
In practice, there’s no real difference. Both terms usually refer to an agency that offers search engine optimization as part of their digital marketing work, including technical SEO, keyword research, and link building.
How do I know if an SEO agency is using black hat SEO?
If they guarantee rankings, sell thousands of backlinks, or refuse to explain their link building process, that’s a red flag. A good SEO agency should follow white hat SEO practices and focus on long-term, sustainable growth.
Should I hire a local SEO agency or a national SEO agency?
If your business depends on location-based searches, a local SEO agency is usually the better fit. If you want scalable organic traffic across broader keywords, you’ll need a national SEO company with a stronger content and link building strategy.
What should I expect from a good SEO company in 2026?
A good SEO company should combine technical SEO, keyword research, and content marketing with strong link building. They should also understand AI visibility, since AI Overview results and AI tools now influence how users discover brands.
