How to Choose the Right SEO Agency: 9 Things Every Business Should Consider

Choosing the right SEO agency can be the difference between generating sustainable growth through organic search and investing in a strategy that delivers little commercial impact.

Whether you're an eCommerce brand, B2B business, SaaS company, or local service provider, selecting the right search marketing partner requires more than comparing proposals and monthly retainers.

The best SEO agencies don't just improve rankings. They help businesses increase online visibility, attract qualified traffic, improve conversion rates, generate leads, and drive revenue growth.

Here's what you should look for when evaluating a potential SEO partner.

1. How Long Has the SEO Agency Been Trading?

Search engine optimisation is constantly evolving.

Google updates its algorithms thousands of times each year, whilst developments in AI search, Answer Engine Optimisation (AEO), user experience, technical SEO, and content marketing continue to reshape the search landscape.

An established SEO agency will have experience navigating:

• Google algorithm update
• Technical SEO challenges
• Website migrations
• Content strategy development
• Link acquisition campaigns
• eCommerce SEO
• Local SEO
• Enterprise SEO

Experience doesn't guarantee results, but it does provide valuable insight when unexpected challenges arise.

2. Can They Rank Their Own Website?

One of the simplest ways to evaluate an SEO agency is to look at their own search visibility.

Ask yourself:

• Do they rank for relevant SEO services?
• Are they visible for local search terms?
• Do they publish useful content?
• Are they demonstrating best practices themselves?

If an agency specialises in organic search, technical SEO, content marketing, and website optimisation, their own website should reflect that expertise.

A strong SEO agency should be able to demonstrate how they generate leads through search marketing, not just explain how it works.

3. Review Their Online Reputation

Before signing any contract, spend time reviewing the agency's reputation online.

Check:

• Google Reviews
• LinkedIn Recommendations
• Trustpilot
• Facebook Reviews
• Industry Awards
• Client Testimonials
• Employee reviews
• Look beyond the star rating.

Do clients consistently mention:

• Increased organic traffic?
• Improved keyword rankings?
• Better lead quality?
• Strong communication?
• Commercial results?

Reviews often provide valuable insight into how an agency performs once the sales process is complete.

4. Ask for SEO Case Studies and Client Results

Every agency claims they can improve rankings.

The best agencies can demonstrate it.

Request examples of:

• Organic traffic growth
• Revenue growth from SEO (is the big one)
• Keyword ranking improvements
• Technical SEO projects
• Website migration success stories
• eCommerce SEO results

A reputable SEO agency should be comfortable sharing examples of previous work and explaining how they achieved the outcome.

For example, our work with All About Party Bags Success Story demonstrates how a strategic search marketing approach can help increase visibility, drive traffic, and support long term growth and being our client for over 5 years.

5. Do They Have Experience With Businesses Like Yours?

Different businesses require different SEO strategies.

A B2B lead generation company has very different objectives to a Shopify retailer, local business, or national eCommerce brand.

Whilst many agencies focus on enterprise organisations, it's important to understand whether they have experience helping businesses operating at your level.

Interestingly, ranking a well known household name with significant authority is often easier than helping a growing SME compete against larger competitors.

Why?

Because established brands already possess:

• Strong backlink profiles
• High domain authority
• Significant brand awareness
• Large content libraries
• Existing search demand

Helping smaller brands achieve visibility in competitive markets often requires greater strategic thinking and creativity.

6. Meet the Team Before You Sign

One of the biggest frustrations businesses experience is discovering that the people who sold the strategy aren't the people delivering it.

Before appointing an agency, ask:

• Who will manage our account?
• Who will deliver the SEO strategy?
• Who performs technical audits?
• Who writes content?
• Who reports on performance?

Ideally, the people responsible for delivering your campaign should be involved in the sales process.

This gives you confidence in their expertise and allows you to assess whether they're a good fit for your business.

7. Check Employee Reviews

A great client experience often starts with a great company culture.

Websites such as Glassdoor can provide valuable insight into how an agency operates internally.

Pay attention to:

• Employee retention
• Training and development
• Leadership reviews
• Staff satisfaction
• Company culture

If employees enjoy working there, it's often reflected in the quality of service clients receive.

8. Beware of Agencies That Never Challenge You

A good SEO agency doesn't simply agree with everything you say.

A great SEO agency asks questions.

They challenge assumptions.

They seek to understand the commercial objectives behind the project before recommending solutions.

We spend significant time understanding:

• Business challenges
• Growth objectives
• Customer journeys
• Competitive landscape
• Marketing performance
• Internal capabilities

Sometimes we discover SEO is the right investment.

Sometimes we identify a bigger opportunity elsewhere.

Either way, our responsibility is to provide honest, strategic advice rather than simply selling services.

9. Focus on Business Outcomes, Not Rankings Alone

Rankings matter.

Traffic matters.

Visibility matters.

But ultimately, SEO should contribute to commercial growth.

The best SEO agencies focus on metrics such as:

• Revenue growth
• Organic conversions
• Lead generation
• Customer acquisition
• Return on investment
• Customer lifetime value
• Market share

A page one ranking means very little if it doesn't contribute towards business objectives.

That's why your SEO strategy should always align with wider business goals.

Choosing an SEO Agency Is Choosing a Growth Partner

The best SEO agencies become an extension of your team.

They understand your challenges.

They align with your objectives.

They provide strategic guidance.
