Google March 2025 core update: what it means for your rankings

Google rolled out its March 2025 core update starting on the thirteenth of March and finished on the twenty seventh. It was the first core update of the year and the first since December. Rollouts like this take up to two weeks, and this one ran close to that full period. If your search traffic rose or fell during those weeks the update is the most likely cause.

Core updates arrive several times a year and they are not aimed at any single site. Google adjusts the broad systems it uses to decide which pages best answer a search. The result is that some pages climb, some slip and many stay put. There is no penalty to remove and no single setting to change. The job is to understand the shift and respond calmly.

What actually changed

Google does not publish a detailed recipe for a core update. What we can see from the data and from years of these events is a consistent pattern. Pages that are thin, outdated or clearly built just to rank tend to lose ground. Pages that show real knowledge and answer the question well tend to hold or improve.

One extra feature of this update drew attention. Google's AI Overviews appeared more often during the rollout, especially for topics like travel, dining and entertainment. That matters because an AI Overview sits above the normal results and can change how many people click through to a website.

Why it matters for Australian business

Search is still where many customers begin. A tradesperson looking for parts, a family choosing a cafe or a manager comparing suppliers will often start with a quick Google search. If a core update moves your pages down the list you may see fewer calls and fewer sales without ever knowing why.

The temptation after a drop is to make sudden changes in a hurry. That usually makes things worse. A core update is a signal to look honestly at your content, not a reason to tear your site apart overnight.

How to tell if you were affected

Open Google Search Console and look at your clicks and impressions for the two weeks around mid-March. Compare that period with the month before. A clear step down that lines up with the rollout dates points to the update.

Look at which pages moved rather than the site as a whole. Often a handful of weaker pages drag down the average while your strong pages are fine. Knowing exactly what slipped tells you where to focus.

What businesses can do next

Start with your weakest content. Find pages that are thin, repetitive or out of date and decide whether to improve them or remove them. A smaller set of strong pages usually beats a large set of weak ones.

Add real substance where you can. First-hand knowledge, clear answers and useful detail are exactly what core updates reward. If a page reads like it was written only to please a search engine, rewrite it for the person who will actually read it.

Be patient. Google has said that recovery from a core update often does not show until a later update. Make genuine improvements and give them time rather than expecting an overnight bounce.

Finally keep an eye on AI Overviews in your sector. If Google is answering common questions directly at the top of the page you may need to focus on the kind of detailed content that still earns a click. CMedia can help you review your pages and plan content that holds up as search keeps changing.
