Algorithm Rolled Out –  February 1, 2003

Algorithm Overview: Overall Gist: 

Google used to update in bits and parts back in ancient times (before the days of rolling updates). It’s possible that a significant index update will take several days to complete. In the meanwhile, the SERPs may fluctuate from moderate to wild. Google staged a large fiesta – the Google Dance – 10 times a year, bringing together all of its data centres, as well as its index, cache, and secondary indexes.

Google altered the way the index updates from piecemeal to rolling updates in August 2003. In other words, Google is always changing; most people only notice when the changes are significant. – And some of Google’s changes have gotten a lot of attention. If the 2002 upgrades have names, no one knows what they are because they are so far back in history. However, a September 2002 upgrade was so bad that some on Webmaster World cried out that PageRank was DEAD.

The Cassandra update (2003) was a Google Dance with actual foot-stomping action, indicating that Google had learnt its lesson. Google used Cassandra to target several links from the same website (a process known as cross-linking). SEOs and do-it-yourselfers pick apart the adjustments in thread after thread. Important elements begin to emerge at this point:

  • Link Text
  • Navigational Structure
  • Page Title
  • Links from different sites

Everyone could tell something was wrong since search results were dramatically fluctuating, but there appeared to be no rhyme or reason. “This reminds me of that crapdate in ’02,” as in “This reminds me of that crapdate in ’02.” Things began to calm down after Esmeralda arrived.

Cassandra, Dominic, and Esmeralda arrived one after the other: April, May, and June. Optimizers, marketers, and website owners were all relieved to see Esmeralda come to an end. For four months, all they had to deal with was a little bit of movement here and there; the Google Dance, as it had become known, was no longer a spasmodic movement across the floor.

What Is A Google Core Update?

A Google algorithm upgrade known as a core update has a major influence on search results.

These are big algorithm updates that might have an influence on a variety of websites across platforms and industries. Whether or whether you have a specialized staff of Search Engine Optimizers (SEOs), a Google core algorithm update can have a positive or negative impact on your website.

A deep insight into Boston Update

Boston, Google’s first official upgrade, was unveiled in 2013 at SES Boston, a Northeastern engineering science conference. The basic objective of Google is to alter its algorithm every a month or so. It quickly gives up on that aim in favour of day-to-day modifications. SEOs and webmasters all across the world begin shaking their heads indefinitely.

After recovery, the graph started moving upwards.

Final End Result

While Google would not acknowledge the first recorded algorithm modification, several SEOs noted a major shift in ranks on this day. Many marketers were perplexed since Google provided little details. They had no idea that more consistent changes were on the way. The term comes from the fact that the first Google algorithm change was disclosed and titled during SES Boston. The upgrade featured algorithm tweaks as well as index refreshes, dubbed the “Google Dance” earlier.
