The core algorithm update has already started in 2023: In March, the core algorithm of the search engine was adjusted, and it is expected to be complete within two weeks.
Google is now officially starting to roll out its March 2025 core algorithm update, as we reported that the update was starting from the Google Search Status Dashboard today.
The rollout began on September 12, 2023, and should be fully rolled out to all of Google’s search systems within a couple of weeks.
The company offered few new details beyond when and how long the rollout was expected to take.
“Rolled out the March 2025 core update. This rollout may take as long as 2 weeks to fully complete.”
Core algorithm update What Does This Mean For SEOs
Core updates are broad changes to Google’s main search algorithms and systems.
Unlike smaller updates that may target specific problems, core updates tend to bring significant changes to search rankings for content all across the web.
Webmasters and SEO should monitor how their sites perform in search during the coming weeks as the update rolls out, with expected fluctuations in search visibility and rankings.
While these shifts are common and tend to settle over time after the rollout is complete, they can also result in lasting changes in positioning, depending on how the new algorithm prioritizes quality and relevance in determining results.
How to Make Your SEO More Resilient to Algorithm Changes
Similar to past core updates, Google has not shared specifics around what changes it made to its ranking systems. The company generally advises high-quality content creation rather than attempting to address specific problems when rankings drop following an update.
Keep an eye on your analytics during this time to see if there are any noticeable fluctuations in traffic or ranking; keeping a record of these changes can help understand if any further modifications are needed when the new version has been fully implemented.
Search Engine Journal will keep an eye on the effect of this update and when more information is made available.
