How high does your website rank?
If you have a website, you naturally want to know how well it ranks in the eyes of the search engines. Not only to see how you rank now, but also to determine what improvements can be made.
An important indicator for this is the authority of your domain. It says something about how reliable and valuable your website is rated by search engines and external tools. The higher the authority, the greater the chance that you will rank better in the search results.
In this blog post, we explain exactly what domain authority is, which free tools you can use to check your value and how you can improve it step by step.
Domain authority
Domain authority is a score that indicates how strong your domain is compared to other websites. It is not an official Google value, but an estimate by specialized SEO tools based on the following factors:
The number of backlinks (links from other websites to your website).
The quality and relevance of these backlinks.
The age and reliability of your domain.
The quantity and quality of your content.
The value usually ranges from 0 to 100. The higher the value, the stronger your domain is perceived. New websites often start at 0, while established platforms such as Wikipedia or Bol.com score much higher.
Free tools to measure your domain authority
There are numerous tools that claim to measure your domain authority. But be careful: not every tool has the same amount of data. Therefore, the values may differ. To get a good and reliable picture, we recommend the three most important providers:
Moz

How can you increase the authority of your website?
A high domain authority is not achieved overnight. It's a process that takes time and where consistency is important. Here are some proven strategies:
1. Create valuable content
Publish blogs, articles or guides that offer real value to your target audience.
 
Focus on topics that your target audience is searching for.
2Build quality backlinks
Make sure that other reliable websites link to you.
This can be done through guest blogs, collaborations or mentions in news articles.
3. Improve your internal link structure
Link cleverly between your own pages.
 
This helps search engines understand what your website is about.
4Technical SEO in order
Make sure your website is fast.
 
Use an SSL certificate (https).
 
Optimize for mobile use.
5. Consistency and patience
Authority is built over the long term.
 
Regular publications and optimizations ensure continuous growth.
It is therefore not a score that can be increased within a short period of time, but a process that can take months or years. That's why it's important to have a long-term strategy for your website and set a content plan or goal that you can stick to. More content means more opportunities you can develop for people to find you, and this can happen within your website. But outside of your website, you should also think about content and presence on social media channels and content in video format on a platform like YouTube.
Original and valuable content can complement your website and raise its profile, but in 2025 it is no longer enough to just publish content on your own website. You also need to be present and active outside of your own website. You can do this by being active on social media and creating a brand. You also need to appear in other sources, e.g. by sharing blogs on other websites. And of course, you will be linked to from other sources. 
Increasing your domain authority is not a sprint, it's a marathon. By consistently creating valuable content, working on strong backlinks, getting your technical SEO in order and having an active presence beyond your own website, you build a trustworthy online reputation step by step. So don't think of your domain authority as the end goal, but as an indicator of your brand's growth. Start with small improvements today and you'll find that the long-term results will automatically follow.
