SEO stands for Search Engine Optimization. SEO refers to how well your website shows up in search engines like Google, as well as the techniques and practices you can do to improve your ranking in various search results.

There is no complete science on SEO because search engines like Google constantly change their ranking algorithms and they keep these things secret. However, there are common techniques that people use to improve SEO, such as focusing on keywords in the titles of your pages and in the content of your website.
