How SEO was created

So there was a need for structure and accessibility and for this reason the first search engines in the world were created with the best known being Excite, AltaVista and Yahoo.

The beginning was difficult for SEO as the rules were easy and relaxed. Website designers used practices such as filling content with keywords over and over again, as there were no criteria then and many links, mostly spam, to rank higher in search engines. was created in 1997 and in the early 2000's would take over the internet with innovative SEO settings and criteria.

Google saw an opportunity to do something that other search engines couldn't. They started building algorithms that would reward quality and related content to get users to find what they really wanted.

Since then, many changes have been made to these algorithms and SEO is constantly evolving and changing, making web designers constantly read and use the best strategies and criterias.
