Technical SEO is about improving technical aspects of your website to improve your ranking in the search engines. Examples of technical SEO are: The speed at which your website loads, the user-friendliness of your website & the readability for the search engine of your website.
The basis of a website is the code language from which the website is built. Google sets requirements for the code, because they crawl (read) through this code and from there determine what the content of the website is. The clearer the code, the easier Google can get through this and determine whether the content matches the search query in the search engine.
For almost every website, the organic website visit is one of the most important KPIs to measure. In addition, the number of crawl errors on your website must be as low as possible for search engines to effectively crawl and index your website, it is wise to make all URLs on your website descriptive and well constructed and the loading time of your pages plays a major role in the ranking of your website in the search engines.
