SEO is a set of optimization strategies and practices implemented to increase the visibility of a website and improve its position on the main search engines in organic results. That is to generate natural traffic not deriving from paid ads on engines. The acronym, in fact, stands for Search Engine Optimization, literally: optimization for search engines.
These are targeted and sometimes very complex interventions. It starts with the optimization of the website directly in HTML code, and then moves towards the language, the texts, the incoming / outgoing links and much more. The most used engine in the world is Google and itself is subject to periodic algorithm updates that tend to give relevance to websites rich in content and useful information to the visitor. Indexing a website, therefore, is a complex process and always requires a deep analysis.
