A Short History Of The Google Search Engine Update

Before we launch into the history of Google search engine update, let us take a brief look at the history of how Google itself came about. It began as a research project of Stanford University Ph.D. students Larry Page and Sergey Brin in the year 1996. It was born out of an idea to explore the mathematical properties of the World Wide Web. They created a web crawler that explored this and originally used the Stanford University’s website with the domain google.stanford.edu. In 1997, the domain google.com was registered and in 1998, the company Google was formally incorporated.

This was followed by the filing of their first patent, receiving their first funding and then on, grew from strength to strength. That the word ‘Google’ has replaced the word ‘search’ for many so of us is a testimony to what they have achieved. ‘Just Google it’ is the commonly heard phrase whenever someone is asking for information. Google search engine started getting popular during the early 2000s, and that was when they began selling advertisements associated with the search keywords.

It is now a norm for websites to have their contents adhere to Search Engine Optimization guidelines. And these guidelines are mostly based on Google ranking factors that play an important part in a website being on top in Google search snippets.

Google Search Algorithm

The Google updates are nothing but an update of the underlying Google algorithm used by the search engine. The updates are done to ensure that search the engine remains highly effective in a fast-changing and ever expanding technological scenario. The algorithms, in turn, contain the famed Google ranking factors. Based on what the user searched for, the algorithm lists out the Google search snippets.

Though nowadays most of the updates are seen with endearing names the early Google updates did not have any specific names nor did they follow any naming conventions. When you look into the history of updates, the first named update was “Boston,” called so because it was announced in SES Boston. Also, the naming was done by Webmaster World users. The naming system continued thus without following any specific system. Occasionally Google itself announced the names as well.
