About Algo Updates
Google’s algorithm updates are designed to improve search results and provide users with the most relevant and useful information possible. From the early days of PageRank to the most recent updates targeting user experience and content quality, Google has been on a mission to refine its search algorithms and better understand user intent.
Why Google Updates Its Search Algorithm
Google Search is a complex system that processes billions of queries from users worldwide in multiple languages daily. As a result, Google constantly updates its search algorithm to enhance the quality of results and improve user experience. These updates can occur many times a year and range from small incremental changes to significant updates that affect the search ranking algorithm.
Improving the Quality of Results
Google’s automated systems utilize various techniques to identify and deliver users the most relevant and reliable information. Thanks to continuous updates, Google’s search algorithm has been able to decrease the number of irrelevant results by over 40% in the past five years. Google’s search algorithm sends billions of visits to websites every day, which helps these sites grow their traffic by providing highly relevant results.
Helping Websites Get Discovered
Google helps users discover a wide range of publishers, creators, and businesses. To ensure that Google continues to support these sites and provide searchers with the best possible information, the company makes numerous incremental algo updates weekly. These updates are thoroughly tested and evaluated through Google’s rating process to ensure they improve the quality of search results.
Incremental Updates vs. Core Updates
While most of these updates go unnoticed by searchers, they accumulate to significantly impact the overall quality of Google Search. Google does not share details about all of these updates but shares information when there is actionable information that site owners, content producers, or others might find helpful. Examples of such updates include the automated system that determines whether a product review demonstrates in-depth research or expertise and an update that determines whether the content is mobile-friendly.
Periodically, Google makes more substantial improvements to its overall ranking processes, known as core updates. These updates are likely noticed by people running websites or performing search engine optimization (SEO) but less so by ordinary users. When these updates are coming (or have rolled out), Google gives notice to site owners, explaining that these changes are not due to anything specific they have done but rather to the company’s efforts to improve its content assessment overall.
Core Updates Aim to Increase Relevancy
Google reminds site owners that core updates, like any updates, do not target specific pages or sites. Instead, these updates aim to improve how Google’s systems assess content overall, which could result in some pages that were previously under-rewarded doing better. Google compares the effect of core updates to refreshing a list of the top 100 movies; some new and wonderful movies that never existed before will now be candidates for inclusion, and some reassessed films may deserve a higher place on the list.
The primary aim of core updates is to increase the overall relevancy of Google’s search results, and while some content may do less well, other content will gain more traffic. In the long term, Google’s continual improvement of its search algorithm is how it has continued to improve search and send more traffic to sites across the web every year.
Google’s Guidance and Tools
Google provides guidance and actionable advice to help businesses, site owners, and content creators be successful with search overall. Although following this guidance does not guarantee a site will rank well for every query, it provides insight into how Google’s search algorithm works and what the company considers high-quality content.
Following Google’s core update guidance, businesses, and content creators can help Google understand when they have the most relevant and useful content to display. Google also recommends that sites follow its quality guidelines, implement optimization tips, and use the free Search Console tool available to everyone.
Understanding Google’s search algorithm updates is critical for businesses and content creators looking to improve their online presence. Google’s constant updates to its search algorithm are designed to enhance the quality of search results and user experience. Following Google’s guidance and using its optimization tools can help businesses achieve better search rankings.
There are two types of updates that Google Search goes through to improve the quality of its results constantly: incremental updates and core updates. Incremental updates are minor improvements made to the search algorithm regularly, while core updates are more substantial improvements made to Google’s overall ranking processes.
Google helps connect searchers to content creators, businesses, and other sources by continually improving its search algorithm. As a search marketing company, understanding the importance of these updates and following Google’s guidance can significantly benefit our clients. By keeping up with the latest updates and implementing the best practices recommended by Google, we can help our clients improve their search rankings and connect with more potential customers.
