What are Google's algorithm changes? Why might they matter to your business? Why is it essential to follow news and trends? Does every business owner need to know the basics of SEO? Check out what I have prepared for you.
As an SEO specialist, staying on top of Google’s algorithm updates is not just part of the job—it’s essential to maintain and improving a website’s visibility in search results. Google’s search algorithm is a complex system that determines how websites are ranked for any given query.
To ensure users receive the most relevant and high-quality content, Google frequently updates this algorithm, sometimes with minor tweaks, and other times with broad, disruptive changes known as core updates. These updates can profoundly impact businesses, often shifting search rankings overnight.
For companies that rely on organic traffic, understanding these updates, why they happen, and how to respond to them can make the difference between gaining new customers and disappearing from page one.
Google algorithm updates are changes made to Google’s search algorithm, a complex system used to retrieve data from its search index and deliver the most relevant results to users. These updates can range from minor, daily tweaks to major core updates that significantly impact industry search rankings.
According to Google, it makes thousands of updates each year—over 4,500 in 2020 alone. Most updates are subtle and go unnoticed, but core updates typically occur several times a year and can affect millions of websites globally.
Each update is designed to improve the relevance, quality, and accuracy of search results. They often target specific issues like thin content, manipulative backlinks, page experience signals, or relevance to user intent.
Examples include the Penguin update (launched in April 2012 to combat link spam) and the BERT update (October 2019), which improved Google’s understanding of natural language by processing the full context of words in a sentence.
It’s essential to understand the major Google algorithm updates that have shaped the modern search landscape, each addressing specific challenges in delivering high-quality, relevant search results.
Launched in February 2011, the Panda update aimed to reduce the visibility of low-quality or thin content. It penalized sites with duplicate, plagiarized, or keyword-stuffed content, targeting content farms and encouraging original, valuable content. Upon its initial rollout, this update affected up to 12% of search results.
Released in April 2012, Penguin focused on link profiles, penalizing sites using manipulative link schemes or excessive keyword stuffing to inflate rankings artificially. It pushed the SEO industry toward cleaner, more natural backlink strategies. By 2016, Penguin had become part of Google’s core algorithm and had begun operating in real-time.
Introduced in August 2013, Hummingbird was a complete overhaul of the search algorithm, emphasizing semantic search. It enabled Google to understand conversational and context-rich queries better, laying the foundation for voice search and long-tail keyword optimization.
Deployed in 2015, Rank Brain introduced machine learning to the algorithm, helping Google process unfamiliar or ambiguous queries by analyzing patterns in user behavior. It became the third most important ranking signal, enhancing the interpretation of user intent behind search queries.
BERT (2019) used bidirectional transformers to understand the context of words based on surrounding text, significantly improving Google’s ability to interpret complex queries. MUM (2021), 1,000 times more powerful than BERT, enabled multitask learning across languages and media, enhancing Google’s capacity to answer nuanced, multi-faceted questions.
Google now rolls out broad core updates several times a year, often without detailed specifics. These updates refine how content relevance, quality, and authority are assessed. Their impact can be widespread, affecting rankings across entire industries and reinforcing the importance of producing consistently high-quality, user-centric content.
Algorithm updates can significantly impact your business by altering how your content, products, or services are discovered online.
Whether a search engine like Google adjusts its ranking criteria or a social media platform changes how posts are shown in users' feeds, these updates can lead to sudden drops—or gains—in visibility, traffic, and engagement.
For businesses that rely heavily on digital presence, even a small change in an algorithm can influence sales, lead generation, and customer reach. Staying informed and adaptable is key; by monitoring performance and adjusting strategies in response to updates, businesses can maintain stability and gain a competitive edge.
Create your website, your way
Since the October 2023 core update, many webmasters have reported fluctuations in their Google search ranking. If you’ve noticed a sudden drop in traffic or poor performance on your website, it may be a sign you’ve been affected by a recent Google update.
For instance, the March 2024 and August 2024 core updates are part of a series of core algorithm updates that aim to refine the Google search algorithm. Google also introduced the March 2024 spam update and the December 2024 ones, which target spammy content that could harm user experience.
To monitor your website's performance, check the search status dashboard for insights on how these updates may have impacted your local search visibility. You might see a significant ranking drop if your content doesn’t align with the helpful content update or is deemed low quality.
Remember, the history of Google algorithm updates can explain what changes may be necessary for recovery, especially as we approach the March 2025 core update. Staying informed about each ranking update is crucial for adapting your strategy accordingly. Anyone who has their website, their own business, must know at least the basic Google algorithm update, so it is also important to stay up to date.
