Google March 2025 core update rolling out now
This is the first core update of 2025 and the first core update since December. It will take up to two weeks to roll out.
Google today released the March 2025 core update. Google said this core update “rollout may take up to 2 weeks to complete.”
Google also wrote:
- “Today we released the March 2025 core update to Google Search. This is a regular update designed to better surface relevant, satisfying content for searchers from all types of sites. We also continue our work to surface more content from creators through a series of improvements throughout this year. Some have already happened; additional ones will come later.”
Core updates happen multiple times per year. Core updates can have significant, broad changes to Google’s search algorithms and systems, which is why Google announces them. This is the first core update of 2025.
This core update comes three months after the last core update, the December 2024 core update.
What to do if you are hit. Google didn’t share any new advice specific to the March 2025 core update. However, in the past, Google has provided advice on what to consider if you are negatively impacted by a core update:
- There aren’t specific actions to take to recover. A negative rankings impact may not signal anything is wrong with your pages.
- Google offered a list of questions to consider if your site is hit by a core update.
- Google said you can see some recovery between core updates, but the biggest change would be after another core update.
In short: write helpful content for people and not to rank in search engines.
- “There’s nothing new or special that creators need to do for this update as long as they’ve been making satisfying content meant for people. For those that might not be ranking as well, we strongly encourage reading our creating helpful, reliable, people-first content help page,” Google said previously.

Previous core updates. The first core update of 2024 – the March 2024 core update – was the largest core update ever, according to Google. It started March 5 and completed 45 days later on April 19.
Here’s a timeline and our coverage of recent core updates:
- The December 2024 core update as on Dec. 12 and ended on Dec. 18.
- The November 2024 core update was on Nov. 11 and ended on Dec. 5.

- The August 2023 core update was on Aug. 22 and ended Sept. 7.
- The March 2023 core update was on March 15 and ended March 28.
Why we care. With any core update, we often see large volatility within the Google search results and ranking. These updates hopefully will improve the rankings of your sites or your clients’ sites. But some of you may see fluctuations or even downgrades in Google rankings and organic traffic.
We hope this update rewards you all and sends you lots of traffic and conversions.
I do wonder if this update will have any positive impact for the creators Google had meetings with months ago.
