Best Web Agencies for SEO

Where is the best place to have my website built?

When it comes to a website, SEO provides a solid foundation. So you want to be sure that your new website is ready to perform well right from the start, right? On this page, you’ll find a list of the top 100 agencies in Belgium for your website.

Top 100 Best Web Development Agencies

As an external SEO agency, our goal is to ensure that every website or online store is ready to be found on the web—whether on Google, Bing, Gemini, ChatGPT, or elsewhere…

For that reason, we set out to investigate as an outside party. We delved deeply into the data from Belgian agencies and their case studies.

Our goal: to compile a list of agencies that can create a high-quality website for you.

Important Context

To fully understand the top 100 web agencies, these three pillars are crucial.

How do we come up with this top 100 list?

For this Top 100 list, we’ve compiled an overview of agencies that specialize in web development (websites and online stores).

For each agency, we have included at least three cases for which we created the website.

For example, we analyzed a total of nearly 500 websites.

What data did we use?

We ran several analyses for each website. These were based on data from Ahrefs and Data for SEO—two well-known companies that provide high-quality SEO data.

We watched:

  • Technical Accuracy of the Homepage
  • Website Traffic Volume
  • Number of backlinks from the websites
  • Number of top rankings for websites

So when we talk about websites, we mean the agency’s own website and those of at least three of the agency’s clients.

Data Weighting

For this dataset, we used the following weights.

Websites

  • Influence of the agency’s own website: 40%
  • Impact of agency cases: 60%

The agency website counts for only 40% because there is one agency site and at least three case study websites.

Data

  • Impact of Data on SEO: 60%
  • Ahrefs’ Influence: 40%

Data for SEO carries more weight because it includes technical factors, traffic, and backlinks. Ahrefs does not provide data on technical correctness at this level.

That’s right! It’s actually a list of the top 111 agencies to hire to build a website or online store optimized for SEO / GEO.

Is your agency not yet on the list?

Please send us your name, website URL, and at least 3 client case studies that we can analyze.

We update the list periodically with new entries. This allows us to provide an independent, consistent comparison of agencies in the field of SEO.

Important!

So don’t just have a website built on a whim. A website is step 2 (see below). Make sure your site is based on research and that you set aside time for further optimization even after launch.

Here’s how to get the most out of your site and improve your online visibility.

The Role of Digital Climax in Developing a New Website or Online Store

How We Help Businesses Get Found Online

Being found on the internet (both SEO and GEO) is a completely different job from actually coding a website.

1) Research

Start by researching:

  • Your competitors
  • Interesting keywords that your target audience searches for
  • Data analysis of your current situation
  • What traffic do you already have, and how can we incorporate that through a proper SEO migration?

2) Plans

Using all your research and data, you’ll get to work on effectively designing your website architecture.

We do this using our own architect tool. This makes collaboration with internal teams, other agencies, and us simple and seamless.

3) Support & Migration

We support and analyze the website in the staging environment through interim audits, redirects, strategy…

We’re here to answer questions from both internal teams and web developers. That way, we can work together to build a cohesive whole and achieve the best possible results.

4) Follow up

As soon as your website goes live, the real work begins. Getting search engines up and running, tracking data, making corrections, and ensuring you can continue to grow.

Creating a website is therefore not a one-time project but an ongoing process.

Still, if you want to be found on the internet.

Digital Climax is an agency specializing in SEO. We focus exclusively on search engine optimization. We guide companies through the process of creating a new website tailored to their goals. From there, we oversee the website’s development and monitor the project’s progress.

Afterward, we’ll work with you to continue building a website that’s easy to find. That way, your website won’t just end up lost somewhere on the internet—you’ll ensure it’s easy to find.
