SEO stands for Search Engine Optimization, a compendium of strategies that are applied to a website and whose objective is to place it at the top of the results shown by industry giants such as Google.
When on-page optimization strategies are carried out, they directly improve SEO, increasing traffic and brand visibility.
Generally speaking, it is possible to say that SEO on page optimization comprises a group of strategies that act according to SEO guidelines and are part of it.
However, the terms should not be confused; on-page optimization or SEO focuses on improving the internal elements or configuration of the website.
On the other hand, SEO off page optimization is oriented to improve those aspects that take place outside the website, applying techniques such as linkbuilding and diffusion in social networks.
Together, both are aimed at the correct web indexing in search engines to reach the first places, either in Google or other search engines.
The relevance of on-page optimization for SEO is based on the fact that it is not possible to obtain the best places in the main search engines without it.
It is necessary to have both on-page and off-page optimization in order to apply a proper SEO.
