<div align=justify>Google is in constant activity. A dynamic that causes some anxiety for those SEO professionals who remain alert to the traffic data of their sites every time you announced a major upgrade of the browser.
Let’s review what has been the most significant updates has been one of the most researched and desired algorithms on the planet.

'''Florida Update'''

On November 16, 2003 was the first of Google’s most important updates and one of the most controversial. It was the beginning of the “Google Dance”. The changes, more massive than ever, affecting about 70% of the results. There were sites that disappeared from the top of search results and there were hardly any cases of sites that substantially improved their positions. There were those who said that the update was for an internal Google’s interest to force companies to use Adwords campaigns for their upcoming season.

'''Holiday Update'''

Similar to the Florida update, Google held in late 2004 a new “Google Dance”, which changed its algorithm to show another kind of results that were replicated from server to server and process which did not show the same results search of a server to others.

'''Supplemental Index'''

In November 2006, published the “results supplementarity” consisting of those results pages that had not received any Page Rank. Pages very young who were part of an index of “second division” to be sites showing stable, serious and with a certain reputation (something like the current sandbox effect) to make the jump to the main index was updated more frequently and made up of higher quality websites.

'''Refresh Data'''

Again, an “earth movement” similar to the Holiday Update. In late 2006 a transformation in the search results of major companies affected and, therefore, responsible for their SEO.

'''Update Dewey'''

Since April 2008 there is an acceleration of updates to Google. Changes occur every time unless it is also true, which is available from the company’s search engine, more information about why each of them. The goal, from this moment was to find a higher speed and quality to such updates in the algorithm that yields results.

'''Vince Update'''

March 2009, this update was to “prioritize” marks on certain criteria. Especially in high demand keywords. At first it seemed logical that the big brands occupy the top places to meet certain services requested by users, but that thought, considering the user experience and quality in response to the results, was the one who broke slowly this same update. Not only the big brands can offer great services and democratization had to be evident.

'''Caffeine Update'''

It’s in September 2009 when Google starts to show results in real time. This is a significant and profound change in their servers to be able to show that every day, even in real time instant, is jumping on any “corner” of the Internet. Tons of content posted on the Internet every second, and Google wants to use that content to provide a better proposal related news or results acontencimientos and its reflection in social networks.

'''Mayday Update'''

In May 2010, after Caffeine, Google decided to conduct a very important and interesting update its algorithm. In relation to recent levels of navigation of the sites (those that support the traffic of more specific search criteria), the popularity reward site that the link juice of the main pages of the same portals. That is, content that had more inbound links without giving would be better placed such importance on the importance of higher levels of navigation (which this effect would go down).
We talked long ago of Mayday Google Update on this post.

'''Panda Update'''

In February 2011, Google holds the deepest update of all changes. It will be affected the low-quality sites with duplicate content, too little content or role of advertising. Although Google says only affects 10% of searches, some pages are up to 30% while others have lost half the audience from that on August 12, 2011, this algorithm is effective in Spain.</div>
