Why Does Google Sometimes Announce Algorithm Updates?

If you are responsible for the SEO of a website, you may have noticed that Google sometimes announces algorithm updates.

You may also notice that every so often there is a sudden change in your ranking and traffic – and no explanation for it. Us SEO experts and other folk in the SEO community usually put this down to an unannounced or unconfirmed algorithm update.

What Is An Algorithm Update?

Google’s algorithm is a complex system used by the search engine to index its BILLIONS of websites and provide the search user with the website that best matches their query.

Google search has been around for more than 20 years and has evolved immensely since it launched.  Google is consistently trying to improve the tool for search users, and they do this by updating the algorithm.

Some updates are so small they are hardly noticed by search users or SEO experts. Other algorithm updates are so significant they alter Google as we know it.

If you want your website to do well on Google, you should be keeping track of all algorithm updates, big or small.

Google Algorithm Updates Over The Years

Let’s take a super quick trip down memory lane to some of the biggest Google algorithm updates of the last ten years:

  • 2011 – The Panda algorithm update was rolled out to reduce the number of low quality, spam-filled websites
  • 2012 –Venice was a location-based update that provided search users with products and service closer to them
  • 2012 – the Penguin update was rolled out to penalise black-hat SEO folk who were spamming the search engines and unethically sourcing (buying) backlinks to manipulate the search engine
  • 2013 – the Hummingbird update allowed Google to better understand search queries
  • 2015 – One of many Mobile updates that encouraged web site owners to optimise their websites for mobile use
  • 2015 – The RankBrain update was another huge update that aimed to help Google better understand the intent behind search queries
  • 2016 – The Possum update (hats off to Google for the rather erm…imaginative names) was rolled out to improve localisation of search results
  • 2019 – The Bert update is one of the biggest algorithm updates of the last couple of years. It was rolled out to further improve Google’s understanding of the intent behind search user queries.

Why Does Google Announce Some Algorithm Updates But Not Others?

Google usually announces a lot of its algorithm updates before it rolls them out, particularly if they are going to have a noticeable impact on the search engines.

These announcements allow SEO and marketing professionals to optimise their site and prepare for the upcoming changes.

However, there are a lot of smaller updates and changes that Google does not announce before rolling them out. These are usually picked up on relatively quickly due to changes in rankings and traffic. They are then discussed amongst SEO and marketing professionals on forums and dedicated SEO websites, such as SE Journal.

Sometimes, these updates and changes will then be confirmed by Google. Other times they won’t. In 2018, Google’s John Mueller stated that Google confirms some updates if they are confusing the SEO community.

Why Is It Important To Track Google Algorithm Updates?

Google algorithm updates, whether announced or not, can impact your website.

Some updates help your website rank higher and gain more traffic, other updates damage your website’s rankings and appear to punish your SEO efforts.

Algorithm updates tend to have an impact on organic search traffic, visibility, leads and conversions. And this will go on to impact your conversions, return on investment, and ultimately your revenue. So, it goes without saying, you need to be keeping track of Google algorithm updates.
