SEO has not changed. It evolves little by little as Google improves its search engines to satisfy users.

• The puzzle that makes up the SEO of any URL is based on crawling, indexing, content, and popularity.
• The 3 areas that these pieces encompass are the technical area (crawling and indexing), the quality area (content), and the authority area (brand popularity).
• The first and greatest objective of any web project in SEO is for the world to know it, detect it, and search for it by its brand.
• The important thing when undertaking an SEO project is detecting which areas are failing or can improve, and focusing on it.
