How to Choose an SEO Agency That Can Win Google and AI Search
How to choose an SEO agency is a bigger decision now than it was even a few years ago. Your business needs a partner that wins in Google’s classic search results and also gets your company mentioned in AI answers from ChatGPT, Gemini, and Google’s AI Overviews.
Most guides cover the basics: check case studies, ask questions, avoid guarantees. This one covers those too, plus three things most guides skip: how to test whether an agency shows up in AI search itself, who should own your accounts, content, and links, and a 90-day scorecard that tells you whether the agency is delivering.
The cost of choosing the wrong partner includes your time, money and lost rankings that cannot be recovered quickly. The checks, questions and benchmarks below will help you confidently hire an agency and hold it accountable from day one.
Key Takeaways
- Choose an agency that can win in Google search and get your business mentioned by AI tools like ChatGPT, Gemini, and Google’s AI Overviews.
- Ranking and being cited are now separate jobs. In a recent Ahrefs study, only 38% of pages cited in AI Overviews also ranked in Google’s top 10.
- Spend 15 minutes checking the agency yourself: its own rankings, reviews, AI visibility, and whether its own pages compete with each other.
- You should own every account, all content, and your data. The agency should be added as a user, never the owner.
- Expect a clear plan and visible progress within 90 days, then judge leads and sales over two or more cycles.
Start With Your Goals and Budget
Choosing an SEO agency begins by establishing what success means to your company. Most agencies focus on rankings; however, it is the actual outcomes (phone calls, qualified leads, booked appointments or sales) that matter most to you.
Before contacting any agency, record your baseline performance. This serves as a yardstick to measure every claim an agency makes about its services:
- Your current clicks, impressions, and top queries in Google Search Console
- How many leads come from organic search each month
- Calls and website visits from your Google Business Profile
- Whether ChatGPT, Gemini, or Google’s AI Overviews mention your business when asked about your service
- Whether you need local SEO for your city or region, or national reach
Your budget should be based on the amount of work required to achieve your goals, and not vice versa. SEO works best through consistent, long-term effort over months, not a single one-time fix.
What to Prepare Before the First Call
Agencies give better answers when you give them better inputs. Have these ready:
- Your website and current marketing activity
- Your business goals and ideal customer
- Your main competitors
- Any technical or search problems you already know about
What Makes a Good SEO Agency?
A good SEO agency proves results with businesses like yours, understands both Google and AI search, and keeps a disciplined keyword plan so your pages never compete with each other. Here is what each of those looks like.
Proof That Matches Your Business Model
Request case studies that show how the agency has helped businesses make money the way yours does. An ecommerce company will need to see evidence of increasing revenue. A local service company will want to know the agency brought in calls and quality leads. Ranking screenshots alone don’t tell you whether an agency actually helped a business grow.
When you review a case study, look for:
- What actually changed on the client’s website
- How the agency measured success
- Before-and-after numbers for traffic, leads, and revenue
- The time period for each result
Request references you can call yourself. If an agency has already worked with a business similar to yours, it understands your customer base as well as your specific market. That also reduces the risk you take on when hiring it.
Real Experience With AI Search
Ranking high and getting cited by AI are now two separate jobs. In an Ahrefs study of 863,000 keywords, reported by DesignRush in April 2026, only 38% of pages cited in Google’s AI Overviews also ranked in the top 10. In Ahrefs’ July 2025 study, that figure was 76%.
| Where AI Overview Citations Came From | Share of Cited Pages |
|---|---|
| Pages ranking in Google’s top 10 | 38% (down from 76% in July 2025) |
| Pages ranking 11 to 100 | Just over 30% |
| Pages ranking beyond 100 | 31% |
That means a ranking report alone no longer tells you whether AI tools are mentioning your business. ChatGPT also relies heavily on what it already knows: Ahrefs data reported by Search Engine Journal on October 12, 2026 found only 14.4% of free, logged-out ChatGPT responses included a web search. Mentions of your brand across the web matter more than ever.
A strong agency can explain how it earns AI citations and how it measures them. Ask it to show you how it tracks mentions in ChatGPT, Gemini, and AI Overviews separately from normal rankings, and whether it has tested those methods on its own website first. Our AI search optimization services are built around this kind of tracking.
One Page for Every Keyword
A quality agency will assign every one of your target keywords to one specific page of your website. When two pages compete for the exact same search term, it creates competition (called keyword cannibalization) that typically leaves both pages with less search traffic than either could have had.
Ask for a keyword map: a document that shows which page targets which keyword, with no overlap. At Gadgetlesstech this is a standing rule. Every keyword belongs to exactly one page. Our keyword mapping service explains how we build that map.
Clear signals from pages to keywords help AI systems understand what each page is about. This also increases the likelihood you’ll be found in both search results and AI answers.
Check Any Agency Yourself in 15 Minutes
Before any sales call, run these quick checks. They show whether an agency practices what it sells.
- Search its own service and city. Look up something like “SEO agency” plus the agency’s city. A strong agency shows up near the top. If it can’t rank itself, be cautious.
- Read its Google Business Profile reviews. Look at recent reviews and how it responds to negative ones. Calm, specific replies are a good sign.
- Ask AI tools about it. Ask ChatGPT, Gemini, and Google “best SEO agency in [their city]” and “what does [agency name] do.” See whether the agency appears and whether the description is accurate.
- Check its own pages for overlap. Search “site:theiragency.com” plus one of its service keywords. If several of its own pages compete for the same term, it may not map keywords carefully for clients either.
- Look for real authors and dates. Its blog should show who wrote each post and when. Hidden or vague authorship is a weak signal.
- Verify its case studies. Ask for the client’s name or a reference you can contact. Claims you can’t verify don’t count.
Questions to Ask Before You Hire
Asking the right questions will tell you whether an agency will be an investment or simply an expense. Below are the questions to ask, and what a good answer sounds like.
- What would you audit first on our site, and why? A good answer names specific technical, content, or local issues, not a generic package.
- Who will do the work day to day? Look for named people and roles, not “our team.”
- Can we see a sample monthly report? It should show traffic, leads, and conversions, not just rankings.
- How do you track mentions in ChatGPT, Gemini, and AI Overviews? A strong agency has a clear method and reports on it.
- Will you give us a keyword map? You want one target keyword per page, written down before work starts.
- What happens in the first 90 days? Expect a specific plan, not “we’ll see.”
- How do you build links, and can we see examples? Good agencies show real placements and explain how they earned them.
- What are the contract length and cancellation terms? Get notice periods and exit terms in writing.
- Who owns the content and accounts? The answer should be: you do.
For local businesses, our guide to what to ask a local SEO agency before hiring them goes deeper.
Who Owns Your Accounts, Content and Links?
All of the accounts that matter to your business need to be owned and controlled by you. To do this, you must have administrator rights to:
- Your domain and hosting
- Your website login
- Google Search Console and Google Analytics 4
- Google Business Profile
- Any ad accounts
You should add the agency as a user on the accounts you own, and not let it build accounts under its own login. If the agency creates the accounts under its login, it controls them. That means if the relationship ends, you may no longer have access to your data, your search history or your reviews.
Any work an SEO agency does for you, such as your website’s content, reports and keyword research, should belong to you once you’ve paid for it.
Get the Exit Terms in Writing
Before you sign, confirm:
- How much notice you must give to cancel
- Which reports, files, and logins the agency hands over when you leave
- That no penalty or fee traps you into staying
You should never feel locked into a contract with an agency because you can’t access your own accounts or content.
Red Flags to Watch For
The biggest red flags include guaranteed rankings, secret methods and contracts that give the agency ownership of your accounts.
- Guaranteed rankings. Google’s own guidance on hiring an SEO says no one can guarantee a #1 ranking on Google. See our answer to whether a local SEO company can guarantee first page rankings.
- A “special relationship” with Google. Google’s guidance also warns against anyone claiming a special relationship with Google or offering “priority submit.”
- Vague link building. If an agency won’t explain where links come from, it may be using tactics that break Google’s rules.
- Cheap packages with no clear deliverables. If you can’t see what you’re paying for, you can’t hold anyone accountable.
- Long lock-in contracts. They keep you stuck with a partner that isn’t delivering.
- The agency owns your accounts. That gives it control over your data and makes leaving painful.
- Reports that show only rankings. Without traffic, leads, and revenue, you can’t tell if the work helps your business.
- No answer on AI search. An agency that can’t explain how it handles ChatGPT and AI Overviews hasn’t adapted to how people search now.
- A sales pitch instead of questions. A good first call is mostly the agency learning about your business.
How Much Does an SEO Agency Cost?
SEO agency cost depends on your goals, how competitive your market is, and how much work your site needs. In Ahrefs’ survey of 439 SEO providers, agencies charged an average monthly retainer of $3,209.
| Provider Type | Average Monthly Retainer | Average Hourly Rate |
|---|---|---|
| SEO agencies | $3,209 | $98.90 |
| SEO consultancies | $3,250 | $171.18 |
| Freelancers | $1,348.63 | $71.59 |
| All providers | $2,917 | $111 |
Agencies usually charge in one of three ways:
- Monthly retainer: Ongoing work for a set monthly fee. In the same survey, 78.2% of providers charged this way, making it the most common model.
- Project-based: A fixed price for a defined job, like an audit or a site migration.
- Hourly: Paying for time, usually for consulting or training.
Compare proposals on deliverables, not price alone. Ask who will do the work, what’s included, and what costs extra. For local businesses, our local SEO pricing guide explains what drives the cost.
What the First 90 Days Should Look Like
A good SEO agency works in clear 90-day cycles, long enough to finish real work and short enough to adjust before months are wasted. Use this as your scorecard:
| Timeframe | What the Agency Should Deliver | What You Should See |
|---|---|---|
| Days 1 to 30 | Full audit, recorded baseline report, keyword map, prioritized technical fix list, account access confirmed in your name | A clear picture of where you stand and what gets fixed first |
| Days 31 to 60 | Priority technical fixes done, first pages updated or published, Google Business Profile improvements, first monthly report | New and updated pages indexed, early movement in impressions |
| Days 61 to 90 | More content live, internal links added, first AI mention check against your baseline, written plan for the next 90 days | Growth in impressions and long-tail queries, an honest review of what worked |
Judge leads and sales over two or more cycles, not one. Early wins usually show up as impressions and long-tail searches before they show up as revenue. At Gadgetlesstech we work in 90-day cycles and review every result against the baseline recorded at the start.
Conclusion
Choosing an SEO agency comes down to a few steps: set clear goals and a baseline, check the agency yourself, ask hard questions about AI search and keyword mapping, keep ownership of your accounts, and use the 90-day scorecard to hold the agency accountable.
