Most people shopping for an SEO agency have been burned by one before. If they haven’t, they know someone who has.
That comes with this industry. Anyone can call themselves an expert in search engine optimization (SEO), most of the work happens where you can’t see it, and results take months to show up. That makes it easy for an agency to sell you plenty of activity and very little growth.
I’ve been doing SEO for more than 17 years, first at Comcast and Campbell Soup Company and now running BCC Interactive. This is the guide I’d give a friend who wanted to learn how to choose an SEO agency without getting played.
Key Takeaways
An agency usually costs a fraction of a full-time hire. The average agency retainer runs about $3,200 a month. A mid-level SEO manager costs roughly $125,000 a year once you add benefits.
Nobody can guarantee rankings. Google says so directly. A guarantee is your cue to leave.
Good SEO companies report on leads and revenue. Rankings and traffic are supporting metrics, not the headline.
Ask who actually does the work. Then ask how you'll communicate and how you get out of the contract.
Plan on four months to a year. That's how long SEO typically takes to pay off. Be wary of anyone promising much faster.
Start With What Your Business Needs
You can’t choose the right SEO partner until you know what you’re hiring them to do. Different businesses need very different SEO work.
- Local businesses (dentists, law firms, contractors, restaurants) need local SEO: Google Business Profile optimization, reviews, local citations, and location pages. If most of your customers come from nearby, look for a local SEO marketing agency with a track record in local search.
- E-commerce brands need e-commerce SEO: product and category pages, site structure, and handling thousands of URLs without creating duplicate content.
- B2B and software companies need content that answers the questions buyers research before they ever talk to sales.
- Small businesses usually need small business SEO that focuses on the handful of keywords that drive calls and form fills, instead of chasing traffic that never converts.
Every SEO strategy also pulls from three types of SEO work:
| Type of SEO | What it covers | Why it matters |
|---|---|---|
| On-page SEO | Content, page titles, headings, keyword targeting | Tells search engines what each page is about |
| Technical SEO | Site speed, crawling, indexing, structured data | Makes sure search engines can find and read your site |
| Off-page SEO | Backlinks, citations, digital PR, brand mentions | Builds the authority that helps you rank against competitors |
The ideal SEO agency for your business has real experience with the mix you need. You want an agency that’s done this work for companies like yours before, instead of learning on your dime.
What To Look For In The Right SEO Agency
Once you know what you need, look for a company that checks these boxes:
- Proof in businesses like yours. Case studies with real numbers and client testimonials you can verify. Ask to speak with a current client.
- A clear process. They should explain how they start (usually a technical audit and keyword research), what they’ll prioritize first, and why.
- A real understanding of SEO and your business. Great SEO starts with your target audience. Ask what your customers search for, and how that connects to your revenue.
- Actual SEO specialists. A general digital marketing or marketing agency may offer an SEO service, but the person doing it might split time across ads, social, and email. Ask who on the team does SEO full time.
- Reporting tied to business growth. Organic traffic and rankings tell you things are moving in the right direction. Leads, calls, and revenue tell you whether SEO is paying for itself.
- A communication style that fits you. Some people want a monthly report. Others want a Slack channel and direct access to the people doing the work. Know which one you are.
Ask for a sample client report before you sign. One real report will tell you more than an hour-long sales pitch.
"Before them I had someone who was very unresponsive. Their results were not what I was looking for. I felt like I was getting over-promised and under-delivered."
How To Judge An Agency's Approach To Technical SEO
You don’t need to be technical to evaluate this. Ask them to walk you through what they’d check first on your site. Quality SEO agencies will mention things like:
- Whether Google can crawl and index your important pages
- Page speed and mobile experience
- Broken links, redirects, and duplicate content
- Structured data (code that helps search engines understand details like your business hours, products, or reviews)
If they can’t explain their approach to technical SEO in plain English, they either don’t understand it well or they don’t want you to. Neither is great.
In-House SEO Vs. Agency: What It Actually Costs
Hiring someone full-time feels like more control. It’s also a lot more money.
ZipRecruiter puts the average SEO manager salary in the U.S. at $86,206 a year. That’s salary only. According to the Bureau of Labor Statistics, wages account for 68.5 percent of employer costs for full-time private industry workers, with benefits making up the other 31.5 percent. Do the math and that $86,000 hire costs you closer to $125,000 a year. That’s before SEO tools like Semrush, training, and the months it takes to recruit and onboard someone.
Now compare that to what agencies charge. In Ahrefs’ survey of 439 SEO providers, the average monthly retainer came in at $3,209 for agencies and $1,348.63 for freelancers. That’s about $38,500 a year for an agency.
| In-House SEO Manager | SEO Agency | Freelancer | |
|---|---|---|---|
| Typical annual cost | ~$125,000 (salary + benefits) | ~$38,500 (average retainer) | ~$16,200 (average retainer) |
| Who does the work | One person | A team of specialists | One person |
| SEO tools | You pay for them | Usually included | Varies |
| Time to get started | Months (hiring + onboarding) | A few weeks | A few weeks |
| If they leave | You start over | The account stays covered | You start over |
In-house SEO makes sense for large sites with a steady content operation and budget for more than one hire. For most small and mid-sized businesses, the math favors bringing in an SEO agency for your company instead. Plenty of companies land in the middle: an in-house marketer owns the big picture, and an agency handles the day-to-day SEO efforts.

SEO Agency Vs. Freelancer
A good freelancer can get results, and they’re usually cheaper. The risk is that everything rides on one person. If they get sick, land a bigger client, or leave the industry, your progress stops.
It’s also rare for one person to be strong at technical SEO, content creation, link building, and local search all at once. An agency brings a full team, so each piece of your SEO strategy gets handled by someone who does that work every day.
That doesn’t mean you need an agency that provides a wide range of every marketing service under the sun. You need the right agency for your specific needs, with depth in the SEO work that moves your business.
If your budget is tight and you need one specific project done, like a technical audit, a freelancer can be the right call.

Questions To Ask An SEO Agency Before You Sign
Bring these to every sales call. How an agency answers tells you more than their portfolio.
| Question | A good answer | A red flag answer |
|---|---|---|
| Who will actually work on my account? | Names, roles, and direct access | "Your account manager handles everything" |
| How do you measure success? | Leads, conversions, and revenue | Rankings and traffic only |
| What happens in the first 90 days? | Audit, keyword research, a prioritized fix list | "We'll optimize your site" |
| How long until I see results? | A range, with reasons | "Page one in 30 days" |
| How do you build backlinks? | Explains the process and shows examples | "We have a network" |
| Who owns the content, accounts, and data? | You do. All of it. | They do |
| How do I get out of the contract? | Clear exit terms | A 12-month lock-in |
| How are you handling AI search? | A measured, specific plan | Guaranteed ChatGPT citations |
SEO Metrics A Good Agency Should Report On
Not all SEO metrics are equally useful. Some tell you whether SEO is making you money. Others just look nice in a slide deck.
| Metric | What it tells you | How much weight to give it |
|---|---|---|
| Leads and conversions from organic search | Whether SEO is producing customers | The most important number |
| Organic traffic to key pages | Whether the right people are finding you | High, if it's traffic to pages that convert |
| Rankings for target keywords | Where you show up in search results | Medium. Useful as a leading indicator |
| Branded search volume | Growth in brand awareness | Medium, especially over time |
| Domain authority | A third-party estimate of your site's link strength | Low. Google doesn't use it |
Domain authority deserves a quick note. It’s a score created by SEO tool companies, not Google. It can be a handy comparison point, but an agency that reports it as a headline win is focusing on the wrong thing.
SEO Agency Red Flags (Including Ones You Should Ask Us About)
Some of these apply to agencies like ours. Good. You should ask us about them too.
1. Guaranteed rankings. Google’s own guidance is blunt: “No one can guarantee a #1 ranking on Google.” Agencies that guarantee rankings often hit the target with keywords nobody searches for.
2. Long-term contracts with no way out. If an agency is confident in its work, it doesn’t need to trap you.
3. Reports that stop at rankings and traffic. Ranking for the wrong keywords won’t grow your business. Your reports should connect SEO performance to leads.
4. Mystery link building and shortcuts. Cheap backlink packages, keyword stuffing, and mass-produced content can get your site penalized. If they won’t explain how they build links, walk away.
5. You don’t own your own stuff. Your website, content, Google Business Profile, and analytics accounts should belong to you, full stop.
6. Promising big results fast. Google has said that SEOs typically need four months to a year to help your business first implement improvements and then see potential benefit. Short, focused engagements are fine. Anyone promising long-term results in 30 days is guessing. That timeline applies to us too. We build every engagement around what your business needs, whether that’s ongoing work or one focused project. Either way, the work starts right away, and the traffic and leads it sets up keep building for months after.
7. They sell everything. SEO, ads, social, web design, video. Ask what they’re actually best at. An agency that does everything often does most of it at an average level.
8. AI search promises. Anyone guaranteeing your brand will show up in ChatGPT or Google’s AI Overviews is overselling. Nobody controls those answers.
9. No experience in your industry. You don’t want to be an agency’s first client in your space. Hold us to this one too. Our case studies span a lot of ground, from local fitness studios to a multi-state cannabis retailer. If we haven’t worked in your industry, you’ll hear that from us on the first call, not three months in.
How To Choose The Right SEO Agency In Five Steps
- Write down your goal. More calls, more demo requests, more online sales. Be specific.
- Shortlist three agencies with results in your industry or business type.
- Ask every question in the table above, and compare the answers side by side.
- Check references. Talk to at least one current client of each agency.
- Choose an agency that shows you a clear plan for the first 90 days, with metrics tied to your goal.
Remember that SEO is a long-term investment. The agency you pick should be one you’d trust with your website for years, even if you start with a shorter engagement.

Frequently Asked Questions
Most agency retainers fall somewhere between $500 and $5,000 a month, depending on your competition and scope. In Ahrefs’ survey, the most common monthly retainer range overall was $501 to $1,000, but low price usually means low hours.
Plan on four months to a year for meaningful results. You’ll often see early signals, like new keywords ranking and pages getting indexed, sooner than that. SEO is a long-term investment, and results build over time.
For most small and mid-sized businesses, an agency costs less and gives you more specialists. In-house makes sense once your SEO needs justify a full team.
You can handle the basics: set up your Google Business Profile, write helpful content, and fix obvious site issues. Competitive keywords, technical audits, and link building usually need an expert.
If most of your customers come from local search, look for real local SEO experience. That matters more than whether the agency is in your city.
Audit your site, research keywords, review your competitors, and give you a prioritized plan. If you’re a month in and don’t know what they’re working on, ask.
