More information about the website tool collection

This is how the website check works!

Simply enter the URL and have the website checked. The analysis usually only takes a few moments. After the check, you will automatically be taken to the overview page of the check, the dashboard.

Here you can find the total score, which shows the total number of points determined for the website. In addition, there is a detailed overview of important parts of the website, from structure to technology.

The ToDo list shows the urgency of the errors found and the ranking reflects the position of the website in comparison with other websites that have already been checked. The tabs on the left finally lead to more detailed information, from meta elements to the content of the page structure.

All entered URLs remain unpublished and anonymous.

Why a website check?

Our website check is intended to give you suggestions for improving your website so that it can be found by search engines in the future and displayed correctly by modern browsers.
Please note, however, that an online tool cannot replace the know-how of an expert.
However, the results of the analysis illuminate the technically evaluable aspects and can provide suggestions for optimization.

Website Check History & Updates

Our website check was created as an in-house project in 2014 and has grown continuously since then. Originally programmed as a little helper for our agency business, it quickly became clear that website analysis can be helpful for every website owner. After we made the website tool online & publicly available, not only the range of functions grew over time, but also the number of users.
