An SEO audit is a comprehensive process for evaluating the visibility of a website in search engines. By reviewing various aspects of the website that relate to search engine optimisation (SEO), weaknesses, strengths and potential for improvement can be identified. The aim of an SEO audit is to develop recommendations for action that will help to improve the website's ranking in search engines such as Google, which in turn can increase traffic and conversion.

The audit can be carried out on both a technical and content level. Technical factors include checking the website structure, loading times, mobile user-friendliness, internal and external links, as well as the implementation of tags and metadata. Content aspects focus on the quality and relevance of the website content, keyword strategies and the user experience.

An SEO audit is often the first step in a long-term SEO strategy and is usually repeated at regular intervals to monitor progress and react to changes in the search engine algorithm or the competitive environment.
