The History of SEO
The story of SEO (Search Engine Optimization) is intertwined with the evolution of the modern search engine. The history of SEO is the history of the search engine, the devices we use, and the internet itself.

The Wild Frontier of 90’s SEO
Early search engine ranked website pages based on the amount of times the queried search term was found on the page. This led to people stuffing their web pages full of often-searched keywords. This practice overflowed into excessive meta-tagging of pages. Many optimizers also engaged in churning out spammy, low-quality backlinks to improve their SERP position. These bad practices were specifically targeted by Brin and Page as they developed Google. Their new search engine would rank websites based on keyword relevancy AND content quality.
2000 – 2002 SEO’s Intermediate Years
This time period was a struggle as search engine developers looked for ways to guide and motivate website owners to optimize their content the right way. Google labored to separate advertising from the function of the search engine. They provided guidelines on how to optimize website content the right way. This is commonly referred to as “white hat” SEO. However, without ranking penalties for bad behavior it did little to allay exploitative, “black hat” practices.
