The term “search engine optimization” (SEO) was first used in 1997, but the practice of optimizing websites for search engines actually dates back to the early days of the internet. In 1991, the first website was created, and by 1993, there were already over 600 websites online. As the number of websites grew, so did the need for ways to find them.
Early search engines were simple text-based indexes, and they ranked websites based on factors like the number of times a keyword appeared on a page. This led to some unscrupulous webmasters stuffing their pages with keywords in an attempt to game the system.
In 1996, Larry Page and Sergey Brin developed a new search engine called BackRub. BackRub used a more sophisticated algorithm to rank websites, taking into account factors like the number and quality of inbound links. This algorithm, which became known as PageRank, is still used by Google today.
As Google became more popular, so did the practice of SEO. SEO professionals began to develop techniques to improve a website’s ranking in Google’s search results. These techniques included optimizing the website’s content, building backlinks, and using social media.
SEO has evolved over time, and the techniques that work today are constantly changing. However, the basic principles of SEO have remained the same: create high-quality content, build relevant backlinks, and optimize your website for the right keywords.
