These are called core updates, and Core updates are meant to make sure we’re giving users helpful and trustworthy results overall. This page tells you more about how core updates happen and what peoples can do to check and maybe make content better.
How Google Core Updates Works?
Core updates work by making significant changes to Google’s search algorithms and systems. These updates are broad in scope and are aimed at improving the quality and relevance of search results for users. During a core update, Google assesses various factors related to websites and content, such as relevance, quality, expertise, and trustworthiness.
Google updates result in changes to the rankings of websites in search results, with some sites experiencing increases in visibility while others may see decreases. Google’s goal with core updates is to ensure that the most relevant and authoritative content is displayed to users when they perform searches.
To adapt to core updates, website owners and content creators should focus on delivering valuable, relevant, and high-quality content that meets the needs of their target audience. This may involve improving the depth and breadth of content, enhancing user experience, and building credibility through authoritative sources and expertise. Regularly monitoring and analyzing website performance can also help identify areas for improvement in response to core updates.
Google Algorithm Updates 2015
In 2015, Google implemented several significant algorithm updates that aimed to improve search result quality and relevance. Here’s a breakdown of the key updates from that year:
RankBrain (October 2015): Google introduced RankBrain, an algorithm powered by machine learning, on October 25, 2015. RankBrain helps to rank webpages by analyzing various ranking factors and determining which pages are most relevant to users’ queries. It continuously learns and adapts to better understand search intent and deliver more accurate search results.
Panda Update 4.2 (July 2015): On July 18, 2015, Google released an update to its Panda algorithm, known as Panda Update 4.2. This update aimed to refine and improve the Panda algorithm, which focuses on identifying and penalizing low-quality or duplicate content. By enhancing the Panda algorithm, Google aimed to provide users with higher-quality search results.
Quality Update (May 2015): In May 2015, Google made significant changes to its search algorithm, referred to as the Quality Update. Although Google did not officially announce this update, it was later confirmed by Search Engine Land. The Quality Update likely involved adjustments to how Google evaluates and ranks webpages based on their quality, relevance, and user experience.
Mobile-Friendly Update Part 1 (April 2015): On April 21, 2015, Google launched the first part of its Mobile-Friendly Update, aimed at improving the ranking of mobile-friendly web pages in mobile search results. This update was crucial as it encouraged website owners to optimize their sites for mobile devices, considering the increasing prevalence of mobile browsing.
Florida
Florida marked Google’s inaugural significant algorithm update, eliciting a widespread outcry.
Google aimed to prevent the effectiveness of manipulative SEO tactics, intending to make it more challenging for websites to achieve high rankings.
Regrettably, this update resulted in the closure of numerous websites, including some mistakenly affected ones, just ahead of the lucrative holiday season. Following this incident, Google pledged to refrain from implementing major changes during holiday periods, a commitment that endured until 2011.
Fritz
During this update, Google transitioned from conducting a single monthly algorithmic update known as the “Google Dance” to indexing pages daily or even more frequently.
This shift marked the end of the period when rankings would fluctuate dramatically over a span of six to eight days.
Instead, Google began implementing numerous minor changes on a daily basis, leading to what was termed “everflux.”
