Best SEO Companies in the World Based on Search Metrics (Over 38784 Agencies Checked)

I have always been fascinated by lead generation sites, and even sold one recently for $190k. One of the lead generation sites I found during my research was, a lead gen site that ranked for extremely competitive terms such as “seo companies” and “best seo companies”. 

Their business model is to rank for these terms, and then sell ad space to SEO companies. This is all fine and dandy with me, except when you start selling out. In what world is it okay to rank an SEO agency with an organic chart like this, number 1 in Canada?

I’ve been in SEO for nearly 10 years now, and I’ve always been a firm believer in practicing what you preach. I believe that one of the best places to find the best SEO company is on Google.  I even put out a tweet asking if people believe SEO companies should have good SEO. The answer was an overwhelming majority of yes’: That’s why I’ve partnered with Ahrefs to find the best SEO companies in the world based on search metrics. We took a sampling size of over 38784 SEO agencies around the globe and ran them through Ahrefs.

The Methodology Behind it

Having specialized in SEO solutions for a while now, we knew exactly what to look for. Therefore, when we sat down to analyze 38784 SEO companies, we focussed on key metrics to guide our process. These metrics are:
  • Total Traffic
  • Domain Rating (DR)
  • Traffic Value
A blend of these metrics gave us the Indexsy score, which we used to rank these top SEO companies in the world. Let’s look at these metrics in more detail.

1. Total Traffic

So, why should you care how much traffic the SEO company you want to work with has? Because if the SEO company can bring lots of traffic to its site, it’ll be able to do the same for your company. This means more eyeballs on your products and services and, ultimately, more sales and more revenue. So, what exactly is total traffic? Total traffic is an estimate of the organic search traffic a certain website gets each month. Therefore, the traffic is calculated on a monthly basis and is based only on organic search. The organic search part is important because it speaks to the SEO efforts of the company. After all, if you should decide to go with a certain SEO company, you’ll want them to be good at bringing in traffic using SEO tactics and strategies – which is what they should be good at. Consequently, it’s no surprise that our top SEO company – SERP Co has almost 3 million in total traffic. Pretty impressive! Therefore, if you were to work with SERP Co and want to increase your organic traffic, you’d be confident that they’d be able to do that.

2. Domain Rating (DR)

What is Domain Rating? Domain Rating is a website authority metric developed by Ahrefs that runs on a scale from 0 to 100. You may have heard the names Domain Authority and Website Authority. These names essentially mean the same thing.  Domain Rating is an organic metric that shows the overall strength of a website’s backlink profile. The backlink profile is a collection of all the backlinks that link to a certain website. Backlinks are also known as inbound links. They are links that point to your websites from other sites. For example, if website A has a link that leads to your site, this is an inbound link to your site and will form part of your backlink profile. You’ll notice that our top three SEO companies have DR scores of over 70. This could indicate that these SEO companies have really focussed their efforts on getting high-quality links from authoritative sites.  Therefore, in regard to the best SEO companies, an SEO company with a high Domain Rating compared to another that doesn’t could say that it is good at link building.  However, it’s important to note that the Domain Rating score does not exist independently. It’s relative to other factors. This is also why it’s one metric of the three metrics we’re looking at today. Let’s now look at another metric.

3. Traffic Value

To understand traffic value, let’s look at an example. Let’s say that a certain digital marketing agency ranks for the following keywords: best SEO company, SEO specialist, and SEO services. Because of this, the digital marketing agency gets lots of organic traffic when Google users search for this term. So, imagine if this digital marketing agency was using Google Adwords’ PPC platform to get that same amount of traffic from these keywords. Whatever amount they would have spent for this traffic is their traffic value. Therefore, traffic value is the amount a website would pay if it was getting the same amount of traffic from all ranking keywords. So this Ahrefs metric shows you the operating cost of getting the same amount of traffic you’re already getting. Just like with our other organic metrics above, traffic value as a measure of how good an SEO company is doesn’t exist on its own. Nonetheless, it’s no surprise that the top three best SEO companies have traffic values of more than 1 million. Here are the figures:
  • Web FX – 1,541,938
  • Thrive – 1,213,133
  • Cyberclick – 229,000

Summary of the Results

Now that we’ve looked at the methodology and why we looked at these specific organic metrics, it’s time to look at what we discovered. We made one important observation as we were analyzing the data. This was that not all companies that ranked highly on our best SEO companies list were SEO companies. For example, our top three companies are actually digital marketing agencies. Let’s look at a brief summary of our top 10 companies and what they do.

Top 38784 Best SEO Agencies in the World

Principal Findings of the Study

So, what made these best SEO companies stand out from the crowd when it came to the three organic search metrics we looked at above? Let’s find out.

Understanding what made these search engine optimization companies get the top spots will give you a good idea of what you can implement in your own website.

Here are key factors that gave these top SEO companies an edge over their competitors.

1. Distinct Niche

Although not all the companies on our best SEO companies list specialize only in SEO, most of them specialize in digital marketing or marketing services. For example, the top three companies are all digital marketing agencies specializing in digital marketing services.

Why is this important? Because having a specific niche allows you to rank for specific keywords relating to your niche. It also creates trust with your clients because it shows that you are specialized in what you do.

For example, Smart Insights, number 10 on our list, has a domain authority and traffic of over 200,000 organic visitors. This means that these visitors know to come to this company for resources on marketing.

Once you focus on a specific niche, it becomes easier to tailor your SEO efforts to establish your business as a reliable authority in your specific field.

2. A Focus on Traffic

It’s no surprise that the top SEO companies on our list today have high organic traffic. After all, good SEO efforts will often lead to more organic traffic.

Examples of ways you can increase organic traffic to your site include:

  • Having a good keyword strategy
  • Leveraging on-page SEO
  • Creating relevant and user-friendly content
  • Promoting your website content on your social media platforms

3. Quality Backlinks

Quality backlinks definitely matter when it comes to ranking highly on SERPs, and the best SEO agencies know this. This is why the top SEO companies have a high Domain Rating.

The higher the quality and quantity of your backlinks, the higher your website will rank. So it’s not surprising that the top SEO companies have Domain Ratings of over 70. However, remember that if it comes to choosing between quantity and quality when it comes to backlinks, quality will always win.

If you’re not comfortable with sourcing backlinks yourself, you can consider buying backlinks online for a faster and more seamless process. High-quality backlinks also signal to search engines that your content is authoritative.

You can think of backlinks as a vote of confidence. For example, if a high-quality domain links to your content through do-follow links, it gives a vote of confidence to your content. It acts as a referral. This is important because it shows the search engine that your content is relevant, fresh, and authoritative.

4. Service Pages

What better way to show your organic audience what you do than with a button on your navigation bar that leads to service pages? You can either have several pages for each service or one page with extensive information on the several services you offer.

Our number one company – SERP Co – does this well with three different pages for its services: marketing, SEO, and website services.

The advantage or upside of doing this is that you get to reduce your bounce rate because your visitors don’t have to scroll through lots of content to find the services you offer.

In addition to that, you also get to increase your conversion rate because those organic visitors who are looking for the services that you offer won’t have to work too hard to get the details they need.

If you have a good blog section on your website, you could also create different categories based on your services. For example, if you have a website about cars and you offer engine repair services, car cleaning services, and car maintenance services, you can have these as categories in your blog section.

Therefore, if you create content about how to clean your car’s interior, it can go to the car cleaning category, and so on. This way, you get to have an organized blog section and build trust with your visitors.

Some other crucial and actionable tips to keep in mind when dealing with service pages include:

  • constantly creating fresh content
  • conducting extensive keyword research for each service
  • tailoring your content for your buyer persona
  • leveraging internal linking

5. Website Optimization

Website optimization is a big factor in the success or failure of your business. Why? Because our attention span as humans continues to diminish, and if we feel that even one second of our time is getting wasted, we’ll leave.

If your website doesn’t load instantly, your visitors will leave. The top 10 SEO agencies on our list know this and have optimized their sites accordingly. It’s not a coincidence that SERP Co gets over 2 million organic visitors.

This SEO company has fully optimized its website for maximum impact. For example, you’ll notice that the site is fully optimized for mobile. You also won’t have to scroll very far to get to the services that the search engine optimization company offers.

Another SEO company that is doing this right is number 2 on our list – WebFX. The website is easy to scroll, and you also have a button on the right side that can easily return you to the top of the page on the mobile version.

The company has created this website to be fully user-friendly. Therefore, this is exactly what you should aim for. If you make it easy for visitors to use your website, they’ll keep coming back and even bring their friends with them.

This will, in turn, increase your total traffic and reduce your bounce rate, which will signal to the search engine that your web pages are actually offering value.

Some simple things that you can do to ensure that your website is optimized include:

  • delivering a seamless mobile experience
  • ensuring the site loads in less than 2 seconds
  • creating high-quality and relevant content
  • building better backlinks
  • designing your website with user intent at the forefront
  • undertaking extensive keyword research
  • making your site visually appealing
  • maximizing social sharing

Your website is the online home of your business. It acts as a 24/7 salesperson whether you are around or not. Therefore, although this is our last point, it is arguably the most important because it forms the foundation for everything else.

You can apply the best keyword strategy and do amazing backlinking, but if your website is not user-friendly, all that effort can easily go down the drain.

Therefore, always ensure that your website is properly optimized for the best results.
