How to Choose an SEO Agency

Are you trying to find the right SEO agency for your business?

Get ready — because there are hundreds of options out there, and it can feel overwhelming.

Just search “best SEO agency” on Google, and you’ll see endless results.

Every company promises amazing results, but not all of them actually deliver.

That’s why doing your research before making a decision is so important.

The SEO agency you choose will play a big role in how well your website performs online.

In this guide, you’ll learn simple and effective steps to find a trusted SEO company Perth that truly fits your business needs.

What Is an SEO Agency?

An SEO agency is a company that helps businesses improve their visibility on search engines like Google.

Their main goal is to make your website appear higher in search results so that more people can find you online.

To do this, they use different strategies such as:

• Optimising your website content
  
  

• Fixing and improving your website structure
  
  

• Building quality backlinks from other websites
  
  

In simple words, an SEO agency makes sure your website gets seen by the right audience when they search for products or services related to your business.

What Services Do SEO Companies Provide?

SEO covers a wide range of tasks, which is why most agencies offer complete, all-in-one services.

However, some agencies only focus on specific parts of SEO. That’s why it’s important to understand what services they provide before choosing one.

Here are some of the main services that SEO companies usually offer:

1. Keyword Research

Keyword research is one of the most important parts of SEO. It’s the foundation of every successful SEO plan.

An SEO company studies what words and phrases people use when they search online. They check how many people search for those terms and how much competition there is. This helps them find the best keywords to target for your business.

For example, if you run a bakery, they might discover that people often search for “best bakery near me” or “freshly baked bread.” These keywords can then be used to attract more visitors to your website.

2. On-Page Optimisation

On-page optimisation means improving different parts of your website so that search engines like Google can easily understand and index it.

An SEO agency helps you optimise key elements on your web pages, such as:

• Title tags
  
  

• Meta descriptions
  
  

• Headings
  
  

• Content layout
  
  

• Website structure

These improvements not only help your website rank better on Google but also make it easier and more enjoyable for visitors to use.

3. Content Creation

Content creation is a key part of SEO. SEO agencies create high-quality and relevant content that helps your website attract and engage visitors.

This content can include:

• Blog posts
  
  

• Articles
  
  

• Product descriptions
  
  

• Infographics

Interesting fact: Websites that regularly publish blog content have 434% more indexed pages on average — which means more chances to appear in search results.

4. Link Building

Link building means getting other websites to link back to your site. These links are called backlinks, and they show search engines that your website is trustworthy and valuable.

An SEO agency helps you earn high-quality backlinks from reliable and relevant websites.

The more strong backlinks your website has, the higher it can rank on search engines like Google.

5. Technical SEO

Technical SEO focuses on improving the backend and technical parts of your website to help it perform better on search engines.

An SEO agency works on areas like:

• Website loading speed
  
  

• Mobile-friendliness

Here’s an interesting fact: about 53% of mobile users leave a site if it takes more than three seconds to load. That’s why having good technical SEO is essential to keep visitors on your website and improve your rankings.

6. Local SEO

Did you know that 46% of all Google searches are for local information? That’s why local SEO is so important for businesses that serve a specific area.

Local SEO focuses on making your website more visible in local search results.

SEO agencies do this by:

• Optimising your Google My Business profile
  
  

• Listing your business in local directories
  
  

• Creating content that targets your location or city

These steps help local customers find your business more easily online.

7. Analytics and Reporting

SEO agencies regularly share reports that show how your website is performing. They track important metrics such as:

• Website traffic
  
  

• Keyword rankings
  
  

• Conversions

These reports help you see what’s working well and where you can make improvements to get even better results from your SEO strategy.

How to Choose an SEO Agency in 15 Steps

Did you know that 82% of businesses prefer hiring an SEO agency instead of managing SEO on their own?

That’s a huge number — and it proves how valuable a good SEO team can be for your online success.

If you’re wondering how to pick the right SEO company for your business, follow these simple and effective steps below.

1. Identify Your Goals

The first step is to clearly understand what you want to achieve with SEO.

Since SEO covers many areas, it’s important to know your main goals before reaching out to an agency. The best way to do this is by thinking about the challenges your business is facing.

Here are a few examples:

• How can I improve my website’s ranking compared to competitors?
  
  

• How can I increase my brand’s online visibility and reach more customers?
  
  

• How can I get quality backlinks to build my website’s authority?

Writing down your goals will help you set clear expectations and guide your conversations with the SEO agency.

It’s important to define your goals early because most agencies will ask about them during the first consultation. Being prepared makes it easier for them to understand what you need.

Sometimes, what you think you need may not be what’s actually best for your business.

For example:

You might think running ads will improve your rankings — but the agency might find that content marketing or SEO-focused content would deliver better results in the long run.

2. Ask for Recommendations from Your Network

Most people start by searching on Google for the best SEO agencies, but asking people you know is often a better option.

Why? Because not all online reviews are completely reliable.

Reach out to your business contacts, friends, or industry peers and ask if they’ve worked with any SEO agencies they would recommend.

You’ll likely get honest feedback based on real experiences — something you can’t always find in online reviews.

However, don’t rely only on recommendations. Even if someone you trust suggests an agency, make sure to research and check them yourself.

List down a few recommended agencies and compare their services, experience, and client results before making your final choice.

3. Make a List of Potential SEO Agencies

As mentioned earlier, the next step is to create a list of SEO companies you might want to work with.

Here are a few simple ways to build your list:

• Ask for Referrals: Start with recommendations from friends or business contacts. Trusted referrals often lead to good agencies.
  
  

• Search Online: If you don’t get enough referrals, look for SEO agencies through Google or other search engines.
  
  

• Use Social Media: Platforms like LinkedIn, Facebook, or X (Twitter) can help you find active and reputable SEO companies.
  
  

• Attend Industry Events: Business events or marketing conferences are great places to meet reliable agencies.

When searching online, be careful with the keywords you use.

For example, if you want quality SEO services at a reasonable price, avoid searching for “cheap SEO agencies.” These often focus on low cost instead of real results. Instead, look for terms like “affordable SEO services” or “trusted SEO agency.”

4. Review Their Website

Once you’ve made your list of SEO agencies, the next step is to visit each agency’s website.

Why is this important?

Because a professional SEO company should have a well-designed, user-friendly website that also ranks for relevant keywords.

Think of it this way — it’s like a fashion designer who should look stylish themselves. If an SEO agency can’t optimise their own website, how can they do it for you?

Here’s what to check on their site:

• Clean and modern design
  
  

• Fast loading speed
  
  

• Clear internal links
  
  

• Well-optimised pages and structured content
  
  

• Easy-to-use navigation

In short, focus on user experience. The website should be simple to browse, easy to read, and provide useful information instead of just showing off.

And if you want to dig deeper, you can use free SEO tools to check their website’s backlinks and keyword rankings — just to see how well they’re doing their own SEO.

5. Book an SEO Consultation

After you’ve shortlisted a few agencies, the next step is to schedule a consultation with them.

This meeting helps you understand how each agency works and whether they’re the right match for your business needs.

During the consultation, pay attention to these key things:

6. Check Their Understanding of Your Business

Make sure the SEO agency clearly understands your business goals and the challenges you face.

For example, if you run a local restaurant, it’s better to work with an agency that has experience in local SEO rather than one that only handles general SEO projects.

An agency that understands your industry and audience will be able to create a more effective strategy for your business.

7. Communication Style

Notice how the agency communicates with you. Do they match your company’s style and values?

Ask about how often they hold meetings, who your main point of contact will be, and how regularly you can expect updates or reports.

Good communication is key — you should always feel informed and comfortable discussing your project with them.

8. Passion and Creativity

Choose an agency that shows genuine interest and enthusiasm for your business.

They should bring fresh, creative ideas to your SEO strategy and be focused on helping your company grow — not just on getting higher rankings in search results.

9. Ask the Right Questions

The main goal of a consultation is to ask questions and find out if the agency is a good fit for your business.

You can do this in person or through a video call. Come prepared with a list of questions and don’t be afraid to ask during the meeting.

Here are some examples of what to ask:

• What experience do you have in our industry?
  
  

• How much do your services cost?
  
  

• How do you plan and run SEO strategies?
  
  

• Can you share examples of successful projects?
  
  

• What tools do you use to track progress?
  
  

• How often will you update or communicate with us?
  
  

• How do you adjust strategies for different businesses?
  
  

• Can you share client references?
  
  

• When can we expect to see results?

Make sure you feel comfortable talking with the agency. You should be able to ask questions and share your thoughts freely.

Tip: A reliable SEO agency is open, transparent, and happy to provide proof of their past success or client feedback.

10. Review Their Past Work and Results

A trustworthy SEO agency should be able to show proof of their success. This could be through:

• Case studies
  
  

• Client testimonials
  
  

• Online reviews
  
  

Ask them to share examples of websites they’ve worked on, ideally from businesses in a similar industry or niche.

They should also be able to explain how they achieved those results and what strategies they used.

If they can’t share client names, they can still show performance data from tools like Google Search Console or Google Analytics to demonstrate their work.

This helps you see the difference between results before and after their SEO efforts.

If you’re not sure how to read the data or metrics, don’t worry — just ask them to explain it in simple terms. A good agency will be happy to walk you through it.

11. Ask About Their SEO Strategy

When choosing an SEO agency, it’s very important to make sure they don’t use black hat or unethical SEO practices. These shortcuts can harm your website in the long run.

The best way to find this out is by asking about their strategy.

Ask how they plan to reach your goals and what steps they’ll take. A good agency will give you a clear and transparent plan of action.

If they avoid sharing details or seem secretive, that’s a red flag.

Here are a few helpful questions to ask:

• How will you decide what kind of content to create for our site?
  
  

• Will you use link building as part of your strategy?
  
  

• How will you improve our authority in our niche or industry?

A trustworthy SEO company will always use ethical (white hat) methods and explain exactly what they’ll do to optimise your website.

Stay away from agencies that take shortcuts like:

• Using private blog networks (PBNs) to build links
  
  

• Relying only on AI-generated content
  
  

• Using unfair tactics against competitors

Always choose transparency and long-term growth over quick, risky tricks.

12. Be Careful with Guarantees

One important thing to remember — avoid agencies that make big promises or guarantees.

It might sound great when an SEO company says they can get your website to rank for specific keywords within a set time, but that’s often too good to be true.

No agency can guarantee exact rankings or results in SEO because search engines like Google are always changing.

Instead of giving guarantees, a good agency will share an estimated timeline of when you might start seeing progress — usually within 2 to 4 months for early results.

The time it takes depends on many factors, such as your website’s condition, competition level, and keyword difficulty.

Remember, SEO takes time and consistent effort. You can expect progress, but no one can promise exact outcomes — and any agency that does should be treated with caution.

13. Get to Know the Team

It’s important to meet the people who will be working on your project.

A strong SEO team usually includes experts with different skills, such as:

• Technical SEO specialists
  
  

• Link-building experts
  
  

• Content strategists and writers
  
  

• Designers
  
  

• Web developers

Ask the agency to introduce you to the team members who will handle your account. This helps you understand who is responsible for each part of your SEO strategy.

Also, pay attention to how well they communicate. Since SEO is a long-term process, you’ll be working together for months — so it’s important to feel comfortable and confident with them.

Before you start, agree on how often you’ll communicate and what method you’ll use (like email, video calls, or chat). Clear communication helps keep everything on track.

14. Review Their Pricing

Remember this — there’s really no such thing as a “good and cheap” SEO company.

SEO takes time, effort, and skill, so if it’s too cheap, the quality is likely to be poor.

Here’s an example:

You contact three agencies to optimise your website, write five blog posts per month, and build 15 quality backlinks. Their quotes are:

• Agency 1: $700/month
  
  

• Agency 2: $2,000/month (some experience)
  
  

• Agency 3: $4,000/month (highly experienced local firm)

The cheapest one may sound tempting, but chances are they lack experience or cut corners.

Instead of focusing only on cost, pay attention to quality, expertise, and experience.

Most professional SEO agencies charge between $50 and $150 per hour. So, if someone offers 60 hours of work for just $700 a month, it’s a red flag — something might not be right.

15. Understand the Agreement and Terms Clearly

Before you sign anything, make sure everything is clear and transparent. A well-defined agreement helps avoid confusion later and builds a strong working relationship.

Here’s what you should check carefully:

• Scope of Work: What services are covered in the plan? Are there any hidden or extra charges for additional work?
  
  

• Goals and Metrics: Agree on how performance will be measured. This could include traffic growth, keyword rankings, or conversions.
  
  

• Contract Period: Understand how long the contract lasts, when it renews, and what the cancellation terms are.

Clarity at the start will save you from problems later and ensure that both you and the SEO agency are on the same page.

Common Warning Signs to Look Out For

Knowing how to pick an SEO agency is just one part of the process — you should also learn what to avoid.

Here are a few red flags that signal caution:

1. Promises of Guaranteed Rankings

Be careful if an SEO agency claims they can get your website to rank #1 in a short time. No one can guarantee exact rankings because search results depend on many factors. Such promises usually mean the agency isn’t being honest or lacks real experience.

2. Using Unethical Link-Building Methods

Stay away from agencies that focus on getting a large number of backlinks instead of high-quality ones. Spammy or low-quality links can damage your website’s reputation and hurt your SEO performance over time. Always choose an agency that builds links naturally and from trusted sources.

3. Cheap Pricing Offers

If an agency’s prices seem too low, it’s usually a red flag. Very cheap SEO services often mean poor-quality work or shortcuts that can harm your website in the long run. Quality SEO requires time, skill, and effort—so be cautious with deals that sound too good to be true.

4. No Proof of Past Work

A trusted SEO agency should be able to show examples of their past projects or share client testimonials. If they don’t have any proof of their work, it might mean they are new or haven’t delivered good results before. Always ask to see case studies or reviews before you decide.

Do You Really Need an SEO Agency?

It depends on your goals!

If you want your website to rank better on Google and get more traffic, then yes — hiring an SEO agency can help a lot. These experts know how to boost your online visibility and bring in the right audience.

Since most online journeys start with a Google search, having a skilled SEO team gives your business a strong advantage. Plus, it saves you time so you can focus on managing and growing your business.

When Should You Hire an SEO Agency?

While your business can operate without an SEO agency, having one can make things smoother and help you grow faster.

Here are some situations where hiring an SEO agency makes sense:

1. Launching a New Website

If you’re building a new website, an SEO agency can make sure it’s properly set up for search engines from day one. This helps your site get noticed quickly and perform better online.

2. Drop in Website Traffic

If you’ve noticed your website traffic going down, an SEO agency can find out why and apply the right fixes to help you recover and grow again.

3. Not Enough Time

SEO takes ongoing effort and regular updates. If you’re busy managing your business, letting an agency handle SEO ensures it stays effective and up to date.

4. Business Growth or Expansion

If you’re planning to enter new markets or expand your audience, an SEO agency can adjust your strategy to attract customers from different locations.

5. Competing with Others

Your competitors are likely investing in SEO. To stay ahead or catch up, you’ll need expert help to improve your rankings and visibility.
