Google does not have a fixed schedule for updating its search algorithm. Instead, they continuously work on refining and improving it. This means that updates can occur at any time, and can range from minor tweaks to major overhauls.
Historically, Google has made several updates each year, with some being more significant than others. Broader changes, such as updates to core ranking algorithms, can have a substantial impact on search results.
What is a Search Algorithm
In the realm of Google, a search algorithm constitutes a sophisticated set of instructions that dictate which web pages are displayed in response to a user’s search query.
The primary objective of a search algorithm is to provide the user with the most pertinent and valuable results based on their input. This encompasses a thorough assessment of various factors including keyword relevance, page quality, user experience, and the authority of the information source.
Search algorithms are in a perpetual state of evolution to adapt to shifts in user behavior, technological advancements, and the dynamic nature of the internet. They play a pivotal role in ensuring that search engines furnish users with precise and beneficial outcomes.
Major Google Algorithm Updates Through the Years
Panda (2011): Panda focused on quality, penalizing low-quality, unhelpful, and duplicated content. It emphasized original, high-quality content and significantly influenced SEO practices.
Penguin (2012): This update targeted manipulative link-building practices, favoring authoritative and relevant incoming links. It rendered “link farming” ineffective and reduced the impact of keyword stuffing.
Hummingbird (2013): This update revolutionized Google’s core algorithm, enhancing its understanding of search queries. It shifted from keyword matching to understanding the underlying topic, enabling more natural language processing and ending the practice of targeting similar long-tail keyword phrases.
RankBrain (2015): Operating as a machine learning system, RankBrain improved query interpretation and intent recognition. It addressed the challenge of unfamiliar queries by incorporating environmental contexts such as searcher location, marking a significant advancement in search result accuracy.
Possum ( 2016): This update brought about significant changes in local search results with a goal to improve the relevance of local search results by considering the user’s location and their perceived intent related to location. This update was particularly beneficial for businesses with multiple locations.
Medic (2018): The Medic update had a significant impact on websites in the health and wellness space. It emphasized the importance of expertise, authority, and trustworthiness (E-A-T) for content in these niches. This update highlighted the significance of providing accurate and reliable information, especially in sensitive areas like healthcare.
BERT (2019): BERT enabled Google to better interpret the context and nuances of words in a search query. BERT improved the search engine’s ability to understand the intent behind longer, more conversational queries, which in turn led to more accurate and relevant search results. This update was a significant leap forward in providing users with precisely what they were looking for.
