How to Choose a Good SEO Agency

A business owner using a checklist to evaluate and choose the best SEO agency, illustrating the careful selection process.

Finding the right SEO agency can transform your business. It can also drain your budget and waste months of precious time if you pick the wrong search engine optimization partner. The difference often comes down to asking the right questions and knowing what red flags to look out for before engaging the services of an agency.

Thousands of agencies claim SEO expertise, but many deliver mediocre results. This page cuts through the noise with 10 practical steps that help you find an agency capable of driving real growth for your business.

1) Start with Clear Goals and Realistic Expectations

Define what success looks like for your business before contacting any SEO agency. Vague goals lead to disappointing outcomes. Consider these questions:

  • Are you trying to increase website traffic by 50% within six months?
  • Do you want to generate more qualified leads from organic search?
  • Would you like to improve ranking for specific keywords that drive revenue?

Each objective requires different strategies and expertise. Write down specific, measurable goals. Include target numbers and timeframes. This clarity helps you evaluate agencies based on their ability to deliver what you need rather than what they want to sell.

Budget planning comes next. SEO services typically range from $2,5000 to $10,000 monthly for most businesses. Agencies charging $500 per month seldom deliver meaningful results, while those demanding $25,000 might be overkill unless you’re a major enterprise.

Set a realistic budget based on your business size and growth objective. Remember that effective SEO requires consistent investment over many months. Quick fixes don’t exist in legitimate search engine optimization campaigns.

2) Research Agency Track Records and Reputation

Start your search by gathering recommendations from trusted business contacts. Word-of-mouth referrals often lead to the best partnerships because you can verify results with people you know.

When researching agencies online, focus on third-party review platforms like Google Business Reviews and Clutch. Look for patterns in feedback rather than individual comments. Multiple clients mentioning poor communication suggests a systemic problem, not just one bad experience.

Check how agencies rank for their own SEO. If an SEO agency can’t get their website to rank well for relevant keywords, they probably can’t help yours either. Search for terms like “SEO agency [your city]” and see which companies appear prominently on major search engines.

Examine the quality of their website. Professional SEO agencies invest in well-designed, fast-loading websites with clear messaging. If their site looks amateur or loads slowly, that’s a warning sign about their technical capabilities.

3) Evaluate Experience and Specialization

Industry experience matters more than general SEO knowledge. An agency with healthcare clients understands HIPAA compliance and medical terminology. One focused on e-commerce knows product schema markup and shopping feed optimization.

Ask potential agencies about their experience in your industry. Request case studies from similar businesses, but don’t expect identical results. Good agencies adapt their strategies to each client’s situation.

Team expertise deserves scrutiny, too. SEO requires multiple skill sets, including technical optimization, content creation, and link building. One-person shops often lack the diverse expertise needed for comprehensive campaigns.

Ask about team structure. Who handles technical audits? Content strategy? Link building? Agencies should clearly explain which specialists are responsible for different aspects of your campaign.

4) Understand Their SEO Approach and Methods

Reputable agencies willingly explain their SEO strategies in plain language. They should outline their process for keyword research, technical optimization, content creation, and link building.

Be wary of agencies that claim proprietary secrets or refuse to share their methods. Effective SEO follows established best practices, not mysterious tactics.

Ask specific questions about their approach, such as:

  • How do they conduct keyword research beyond basic tools?
  • What process do they use for technical SEO audits?
  • How do they create content that both users and search engines value?
  • What’s their strategy for earning high-quality backlinks?

Link building warrants special attention. Building top-notch backlinks is integral to SEO success, but many agencies use risky shortcuts. Avoid any agency that mentions buying links, using PBNs (private blog networks), or guaranteeing specific numbers of links.

Ethical link building focuses on creating valuable content that naturally attracts links from reputable websites. Agencies should explain how they identify link opportunities and reach out to potential partners.

5) Examine Communication and Reporting Practices

Transparent communication prevents most client-agency problems. During initial conversations, assess how effectively potential agencies listen to your needs and clearly explain their recommendations.

Ask about reporting frequency and format. Monthly reports are suitable for most businesses, although some prefer quarterly reviews for implementing long-term strategies. Reports should include key metrics like organic traffic growth, keyword rankings, and conversions rather than vanity metrics.

Request sample reports from current clients. Good reports explain what work was completed, what results were achieved, and what’s planned for the coming period. They should tie SEO activities to business outcomes whenever possible.

Discuss their preferred communication methods and availability. Some agencies assign dedicated account managers, while others use team-based approaches. Neither is inherently better, but you should know what to expect.

6) Watch for Common Red Flags

Certain promises should immediately disqualify an agency from consideration. Guaranteed ranking within specific timeframes is impossible to deliver reliably. SEO depends on many factors, including competition, algorithm changes, and your website’s starting condition. Legitimate agencies discuss probable outcomes, not guarantees.

Extremely low pricing often indicates corners being cut. Agencies charging $300 monthly typically outsource work to inexperienced freelancers or use automated tools without human oversight.

Lack of transparency raises major concerns. Agencies should willingly share client references, case studies, and detailed service descriptions. Those claiming everything is proprietary likely have something to hide.

Pressure tactics suggest desperation rather than confidence. Good agencies focus on fit and value rather than pushing prospects to sign immediately.

7) Ask the Right Questions

Prepare some questions to reveal the approach and expertise of the agency, for example:

  1. What’s your process for handling Google algorithm updates?
  2. How do you determine which keywords to target for our business?
  3. Can you walk us through your technical SEO audit process?
  4. What tools do you use for SEO analysis and reporting?
  5. How do you develop content strategies that align with SEO goals?
  6. Who creates the content, and what’s their expertise in our industry?
  7. How do you optimize Google Business profiles?
  8. What’s your approach to citation building and reputation management?

The quality of their answers is more relevant than having perfect responses. Good agencies demonstrate deep knowledge and passion while readily acknowledging what they don’t know.

8) Consider Long-term Partnership Potential

SEO delivers the best results through consistent, long-term effort. Choose an agency you can work with for years rather than switching providers frequently.

Evaluate cultural fit during the selection process. Do their communication style and values align with your business? Do they seem genuinely interested in your success beyond just completing contracted work?

Discuss their approach to strategy evolution. SEO constantly changes as search algorithms update and your business grows. Agencies should explain how they adapt strategies over time rather than following rigid playbooks.

9) Review Contract Terms Carefully

Understand what services are included in your monthly retainer. Some agencies bundle content creation, technical optimization, and reporting, while others charge separately for each service.

Pay attention to contract length and cancellation policies. Many agencies require 3 to 6-month minimums, which is reasonable given the long-term nature of SEO. Think twice about contracts longer than 12 months or those with hefty cancellation fees.

Clarify ownership of any assets created during the engagement. You should retain ownership of content, website improvements, and other materials developed for your business.

10) Test Their Knowledge with Technical Questions

If you have basic SEO knowledge, ask technical questions to gauge their expertise:

Their responses reveal whether they understand SEO beyond basic best practices. That said, don’t eliminate agencies just because they admit knowledge gaps in specialized areas you don’t need.
