How have the latest Google algorithm updates affected me?

Every year, Google updates or tweaks its algorithm hundreds of times. Most of the time, updates don't significantly affect the SERP, and site owners don't even notice. However, there have been a few significant times when Google made updates that caused obvious changes in traffic rankings and rates.

Here's a basic overview of some of these major changes so you can understand how the algorithm has evolved over the past few years.

Panda Update – 2011

This update was first rolled out in 2011, but it has had several updates over the years. In early 2016, Panda was added to Google's core ranking algorithm.

Panda targets spam and weak content that doesn't help end users. Thin content, duplicate content, and content with too many ads are all penalized.

Penguin Update – 2012

About a year after the Panda update, the Penguin update was released, delivering yet another push towards quality content. This update targets spam by reviewing backlinks. It rewards those with quality, organic backlinks, and penalizes those with an artificial backlink profile.

Hummingbird Update – 2013

The Hummingbird update is a change to Google's algorithm to make it smarter at interpreting semantic search. It is designed to help Google better understand purpose and context. This forces marketers to turn to long-tail keywords. It also encourages marketers to develop products based on user intent and needs rather than a keyword.

RankBrain Update – 2015

When the RankBrain algorithm worked, it introduced artificial intelligence into Google's algorithm. This part of the algorithm is capable of monitoring user behavior and responses to queries to 'learn' more about the intent and value of certain pages. It is currently the 3rd most important Google ranking signal.

Mobile Update – 2015

The mobile update forces all sites to be mobile-friendly or risk being penalized in the SERPs. Instead of mobile optimization being reserved for brands at the forefront of the industry, every website needs a mobile version of their website.

Quality Update – 2015

This update, also known as Phantom II, gained attention a few weeks after the mobile update was released. This update rewards sites that focus on user experience and high-quality content while penalizing those with too many ads and certain types of user-generated content. Once again, thin content is hit hard. This could be one of the reasons user-generated sites, like HubPages, get penalized while user-generated sites, like Quora, have an uptick.

AdWords Update – 2016

In Q1 2016, Google fundamentally changed the way paid search listings are displayed on the SERP. They removed the traditional 4-pack placement in the right column (where the Knowledge Graph element appears) and integrated them at the top of the main list. The integration trend will continue, with icons labeling listings as paid ads gradually gaining focus over time.

Interstitial Penalties on Mobile – 2017

This SEO penalty applies to sites running interstitial ads that have blocked users from viewing content on the page. This is not a common penalty for all interstitial ads. Instead, it focuses on intrusive mobile interstitials, and interstitial ads that require users to manually remove them.

Google Update “Fred” – 2017

An unconfirmed alias update, Fred has had a major impact on organic listings, with some sites experiencing a 50 to 90% drop in traffic. Fred's exact parameters were never confirmed by Google, but appear to have disrupted sites that emphasize display ads and/or content-based traffic monetization as well. such as making the aforementioned elements difficult to distinguish from the actual content on the page.

“Medic” Core Update – 2018

The “Medic” core update is an extensive core algorithm update, one that Google makes several times a year. Although Google has not confirmed the specific purpose of this update, it has a major impact on your health, finances, and money on your life page. SEO experts speculate that this Google update has boosted the rankings of high-quality articles offering advice on major life issues, such as finances and health.


Various locations – 2019

The Multisite Update is a tweak that seeks to remove multiple listings from the same domain from the SERP. Many listings are now less visible.

Core September – 2019

This update appears to be a rollback to fix some of the impact from previous core updates.

BERT – 2019

BERT – Bidirectional Encoding Demonstration from Transformer – is a neural network-based technique for natural language processing and is capable of better understanding the full context of your query by looking at all the words in your search and dive deeper into the relevant information you're looking for. This update is so important that Google needs to purchase new and more powerful computer hardware to process the information from the crawling process.

Core January 2020

Better content contributes to this superior user experience, and it's easier for brands to see their material rise on the SERP, regardless of the core update.

Core May 2020

Although COVID-19 launched in 2020 and businesses and websites struggled to catch up to the digital pace of the entire world right away, Google went ahead with a huge core update. called the May 2020 Core Update. Due to the pandemic, search intent has changed, and Google makes it easier for people to find the right answers to their questions with the update.
