How to choose an SEO company - Whiteboard Friday
1. Check Agency Skills and Background
When evaluating an SEO agency, it’s important to go beyond their sales pitch and assess their actual expertise. A reliable agency should combine technical know-how with strategic insight to deliver measurable results.
1.1 Review Past Performance
Website testimonials are often carefully curated, so don’t just take them at face value - dig deeper by reaching out to former clients.
Here’s how to evaluate past performance:
Contact previous clients to confirm testimonials and get honest feedback.
Analyse keyword rankings and traffic growth for the agency’s past clients to see if they’ve delivered real results.
Check their local rankings - does the agency rank for SEO-related terms in your area?
"To find out their real reputation, contact some of their clients directly. You'll find out soon enough if the testimonials are true or not, and you may receive valuable tips from those clients." – Webgator
It’s also worth looking into whether the agency has experience in your specific industry.
1.2 Check Industry Experience
An agency familiar with your sector can make a big difference. They’ll already understand:
The keywords and search intent relevant to your industry
Common technical issues businesses in your field face
The type of content that resonates with your audience
The competitive landscape and its nuances
"Experience is what sets agencies apart. It allows us to solve the toughest SEO problems out there for our clients when no other solutions exist in-house. And that's what's needed now more than ever." – Bruce Clay, Founder and President, Bruce Clay Inc.
Years of hands-on experience in a specific sector can give an agency the edge when tackling complex SEO challenges.
1.3 Verify Professional Credentials
An agency that prioritises professional growth is more likely to stay on top of industry changes. Look for certifications and training from recognised organisations. Here are some key certifications to consider:
Certification Type | Purpose | Typical Investment |
---|---|---|
Google SEO Fundamentals | Basic SEO knowledge | £39/month (audit option free) |
Digital marketing essentials | Free | |
SEO tools and strategies | Free | |
Advanced SEO techniques | £39–£475 per course | |
Conversion and SEO optimisation | £119/month |
For example, in 2023, companies like P&G and Bayer adopted OMCP digital marketing standards for their teams. This led to better marketing performance and a shared understanding of digital strategies across their organisations.
When assessing credentials, make sure they align with your specific needs. For instance, if you’re focused on local SEO, look for agencies with BrightLocal Academy certifications. For e-commerce, prioritise those with platform-specific expertise.
2. Look for Clear Communication
Clear communication is key to a successful SEO partnership. When considering agencies, they should be able to explain complex SEO concepts in simple terms and share regular, transparent updates on your campaign's progress.
2.1 Check Reporting Methods
A professional SEO agency will provide detailed, customised reports on a regular schedule. These reports should cover essential metrics like traffic, conversions, SEO performance, and technical health. Many agencies also use project management tools to share real-time updates, reducing the need for constant meetings.
Report Component | Key Metrics | Frequency |
---|---|---|
Traffic Analysis | Organic sessions, page views, bounce rate | Monthly |
Conversion Data | Leads, sales, revenue from organic search | Monthly |
SEO Performance | Keyword rankings, organic visibility, CTR | Bi-weekly |
Technical Health | Core Web Vitals, crawl statistics, backlinks | Monthly |
Good reports should include:
A summary of key achievements
Insights that explain the data in context
Recommendations for future improvements
Clear explanations of how the results impact your business
2.2 Spot Warning Signs
While clear reporting is important, it's equally crucial to watch for red flags in communication:
Vague Responses
A reliable agency will offer detailed answers about their methods. While some proprietary techniques may remain confidential, they should still be transparent about their overall approach.
Limited Client Access
Trustworthy agencies will connect you with past or current clients to verify their communication practices. They should also outline response times, assign a main point of contact, set meeting schedules, and clarify your level of involvement.
Unclear Deliverables
If an agency avoids specifying what services they will provide, it’s a concern. A good agency will clearly list all the components of their strategy.
The best SEO agencies keep communication open and adjust their strategies based on data and client feedback.
3. Review Work History
Looking into an agency's past projects and achievements can give you a clear idea of their impact and capabilities.
3.1 Analyse Case Studies
Case studies are a great way to assess an agency's ability to deliver results. Look for measurable outcomes like these examples:
Industry | Results |
---|---|
Recruitment | 392% traffic growth and 302% improvement in keyword visibility |
E-commerce | 4,953 extra orders and 58,301 additional organic sessions |
Jewellery | 22,000 monthly visitors and 88% of targeted keywords ranking on page one |
Storage | 49% organic traffic growth and top rankings for location-based terms |
To ensure these claims are genuine, it's a good idea to seek direct feedback from the clients involved.
3.2 Contact Previous Clients
Talking to previous clients helps you get an honest view of an agency's work. Here's how to approach it:
Check Current Rankings: Look at the client’s site on Google to see if their keyword rankings have been maintained over time.
Read Reviews Across Platforms: Check multiple review sites for consistent feedback about the agency's results, communication, and service quality.
Ask Specific Questions: When you get in touch with former clients, ask about the campaign goals, how often the agency communicated, and the overall value they delivered.
If an agency is reluctant to share client references, consider it a red flag. A trustworthy agency should have no problem connecting you with past clients who can vouch for their work.
4. Match Your Business Needs
Choosing an SEO agency that understands your goals is key to achieving lasting success. Their expertise should align with your specific needs, building on their past work and communication skills.
4.1 Set Clear Goals
Before hiring an SEO agency, define your campaign objectives. A skilled agency will ask detailed questions about your business to create a strategy that works. Here are some key areas to consider:
Business Aspect | Questions to Ask |
---|---|
Sales Objectives | • What are your products or services? |
Current Performance | • What are your current organic traffic metrics? |
Marketing Integration | • What other marketing efforts are in progress? |
"A good SEO agency should understand how search engine optimisation fits into the bigger picture of marketing your business to your target audience. That means understanding more than bits and bytes and also understanding the people you are trying to sell to." - Bruce Clay, Founder and President, Bruce Clay Inc.
4.2 Get a Custom Plan
Your SEO strategy should be tailored to your industry, not a one-size-fits-all approach. The agency should provide a detailed plan outlining their services, including:
Technical Implementation
Specify technical fixes, assign responsibilities, and clarify if outside development support is required.
Content Strategy
Ensure the agency delivers clear plans, including:
The number of pages they’ll optimise each month
How many new landing pages they’ll create
A timeline for internal and external content production
Their approach to improving content (e.g., updating existing pages versus creating new ones)
Performance Tracking
Confirm they’ll provide regular reports, customise details for various stakeholders, define how they’ll analyse campaign performance, and use tools to track progress effectively.
For added assurance, grant the agency temporary access to your Google Analytics and Search Console accounts. This allows them to perform an in-depth analysis and offer actionable, data-driven recommendations tailored to your business.
5. Compare Costs and Services
When choosing an SEO agency, understanding their pricing and services is just as important as assessing their skills and communication. Take a close look at what they charge and what they deliver to ensure you're getting good value and avoiding any unexpected costs.
5.1 Understand Pricing
SEO agencies offer different pricing models to suit various business needs. For instance, 53% of agencies prefer monthly retainers, while 85% include their services in packages designed to cover several aspects of SEO. Here's a breakdown of common pricing structures:
Pricing Model | Description | Best Suited For |
---|---|---|
Monthly Retainer | Fixed monthly fee for ongoing services. Typical range: £400–£800 | Long-term SEO campaigns |
Project-Based | One-off fee for specific deliverables. Typical range: £400–£1,600 | Website launches, audits |
Performance-Based | Payment tied to achieving specific results | Businesses with clear KPIs |
Hourly Rate | Charges based on time worked. Typical range: £40–£80/hour | Ad-hoc consultancy |
After choosing a pricing model, examine the specific services included to ensure they align with your goals.
5.2 Review Service Details
It's crucial to get a clear list of what the agency will deliver. Ask for a detailed breakdown of monthly services.
Key services to look for include:
Service Category | Expected Deliverables | Verification Questions |
---|---|---|
Technical SEO | Site audits, optimisation reports | How often are technical audits conducted? |
Content Creation | New pages, content updates | What is the monthly content output? |
Link Building | Acquiring quality backlinks | How do you measure link quality? |
Performance Tracking | Regular reports, analytics | What metrics are tracked? |
When reviewing service details, consider the following:
Contract Flexibility: Check if there's an option to terminate the agreement with one month's notice.
Strategy Updates: Ensure the agency adjusts strategies based on performance and data.
Resource Allocation: Ask for specifics, such as the number of deliverables or hours dedicated each month.
Extra Costs: Confirm whether additional services like content creation or development work come at an extra charge.
Be aware that agencies based abroad might charge higher rates. However, focus on the overall value. For example, an agency charging around £937 per month for a thorough optimisation plan may deliver better outcomes than one offering limited services.
Conclusion
Selecting the right SEO agency is an important decision that can significantly influence your online success. To make a smart choice, focus on five key areas: skills and experience, clear communication, track record, alignment with your business goals, and cost considerations. A thorough review of these factors can help you make an informed decision and protect your investment.
Keep in mind that poor SEO practices might bring short-term gains but can also result in severe penalties, including removal from Google's index. Repairing such damage often takes more time and money than starting with a solid strategy from the outset.
Here are some practical steps to protect your investment:
Speak with former clients and verify results using tools like Open Site Explorer.
Include a 30-day notice period in contracts to ensure accountability.
Examine examples of built links to spot any potential issues.
Request regular and transparent performance updates.
