SEO audit

A (comprehensive) SEO check resulting in a specific list of improvements

Our SEO audit answers questions such as: how well is your company's website organic visibility? And are you leaving any gaps in this? Technical SEO, content and authority: there are many factors that influence your positions in Google. Many developers make free tools that give you some insights, but for real answers, you need our SEO audit.

After this SEO check, you will have a clear overview of all the areas of concern and you can get to work concretely on improving the visibility of your website. With or without our help.

What is a SEO audit? Our approach

A SEO audit is a (comprehensive) SEO check that produces a specific list of improvements. No website or company is the same, so before we start the SEO audit, we discuss the goals and target audience of your website. It is also important to know which search terms you want to be found on and what your competitors are doing. We can help you out with specific SEO advice in this way.

Search analysis and baseline measurement

We start the comprehensive SEO audit with a baseline measurement and a keyword analysis. To do this, we make a list of search terms that people use when they are looking for your product or service. We complement this with:

  • Keyword volumes: the (historical) average number of searches per month on this keywords.
  • Competition: how easy or difficult it is to get into the top 10 search results for this keyword.

We put the list of keywords in our tool as a baseline measurement. After this we know where your webpages rank for and what your market share is in Google for the group of keywords.

Content & on-page seo audit

In the SEO audit, we analyse the current content of your website. We look at on-page SEO factors, such as text, headlines, keywords and internal links. Besides these factors, Google also looks at the quality and value of a page. If too many pages contain 'unhelpful content' or low-quality content, this can decrease the visibility of your entire website.

Technical audit

74% of people leave a mobile website if it does not load within 5 seconds. In the technical SEO audit, we look at the speed and accessibility of your website. We crawl the website ourselves and thereby mimic the search engine. The technical improvements that result from this ensure a more solid foundation for the crawler and therefore lead to a better visibility

Website authority

Search engines value reliability and authority. After all, they want to give the best and most reliable answer to a query. To do this, Google (and other SE's) look at the number of links that go to a website. We check how your link profile compares with the competition and give specific advice on authority.

This is how a SEO audit helps you

You will receive the results of the SEO audit in a clear report. Think of this as a list of improvements for your developer and (content) staff. Of course, we will discuss the report together so that you know exactly what steps to take afterwards. Sometimes you take those steps yourself, but of course we are also happy to help you with them, for instance when dealing with complex technical SEO aspects. If required, we can start a SEO program for a number of hours per month.

Digital content manager Peugeot

Whether it's about content or technical adjustments, it doesn't matter. Martijn briefs this in a very clear way so that it can be implemented locally or by our head office in France. [...] Since the start of our collaboration, we have achieved great results. Keep it up!

Marien van Stegeren

Eigenaar Kitcentrum

When your online onder venture grows, expectations often grow too, in every area. To a large extent, we were in control of SEO and its interpretation ourselves. We found out that our own "general view" was no longer sufficient, so we engaged Bureau Onder. Surprising and clear. We have built up a fine collaboration, partly because Martijn also regularly visits our office with Eline or Mariska (depending on the case), which is very valuable to us!

Marten Stellingwerf


Martijn and Mariska make the SEO story understandable for the layman and are happy to think along with us. It is nice that there is a personal contact moment every month with an extensive report and the opportunity to talk everything through. After just a few months, Onder has already managed to achieve number 1 positions on Google with some of our webshop pages. We are very satisfied with Onder.

SEO Specialist Stella Fietsen

For several years, Onder has been a valued partner of Stella. Martijn is my sparring partner for complex SEO issues and the extra pair of critical eyes that keeps us on our toes. Together, we have achieved nice growth in online visibility, visitor numbers and leads. Onder onder stands out for its short lines of communication and professionalism. They speak our language: don't nag, get down to business. That is what we love!
