The PageRank Algorithm
In 1996, two Stanford students, Larry Page and Sergey Brin, developed the PageRank algorithm as part of a research project for a new kind of search engine. The concept is quite simple: the algorithm calculates the importance of web pages based on the number of links pointing to them. The university filed for a patent in 1998 and received it in 2001.
Google Takes the Stage
In 2000, Page and Brin launched Google, which utilized this new algorithm for its search. They were given exclusive rights to the process by Stanford. What set Google apart from other search engines was how it determined quality. Earlier methods, such as keyword stuffing and meta tag manipulation, were no longer effective. Google’s later update in 2003, further put these tactics to rest. Google’s algorithm was resilient against deceptive SEO practices and provided quality results relevant to the user’s query. Clearly, it was a rousing success.
Google’s Continued Dominance
Google did not stop there. Over the years, they have continuously iterated their search algorithms to improve search quality and user experience. In 2011, they started penalizing websites with minimal or duplicate content. In 2012, they took actions to prevent link spamming. When mobile phones became the dominant platform for searching, Google prioritized loading speeds and mobile-friendly pages. With each step, Google pressures website owners to provide high-quality content to be recognized in search, rather than taking shortcuts to improve their ranking.
Post-Google SEO
Today, SEO is vastly different from what it was in the ‘90s. There are no more shortcuts to improve search rank. Now, site content must be well developed towards serving a user’s needs. Some of the SEO tips from Google’s own website include making your website easy to navigate, using descriptive URLs, ensuring text is easy to read, keeping your content up-to-date, and, of course, having content that is “helpful, reliable, and people first.”

Really solid summary. You clearly show how PageRank changed search and why early SEO tricks stopped working. I like how you connect Google’s updates to the shift toward quality, user-focused content instead of shortcuts.
I was able to learn a lot about Google and their progression of the search algorithm through this blog! It’s a great history overview and backstory of Google and I like the incorporation of pictures and images throughout the blog to break it up a bit.
