March’s Core Update Comes With More Changes Promised. How Do Brands Know What Moved Them?

This article was AI-generated as part of an experimental historical-content project. The date reflects the period being analyzed rather than the date the article was originally written.

Google’s March 2025 core update is four days old. The Search Status Dashboard entry from Thursday is the usual two sentences: “Released the March 2025 core update. The rollout may take up to 2 weeks to complete.” It is the first core update of the year, arriving about three months after the December update.

The note Google posted alongside it is more interesting. As quoted by Search Engine Land, Google called it “a regular update designed to better surface relevant, satisfying content for searchers from all types of sites.” Then came a second sentence: “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.”

That second sentence is the real news, and it raises a question that standard core update advice does not answer.

The attribution problem

Last November I argued that core updates have become close to a permanent condition, and that the sensible response is a regular baseline of what your results look like. That still holds. But a baseline tells you that something moved. It does not tell you why.

The working assumption has been that big movements cluster around named updates. If results for your name shift during an announced rollout, the update is the leading suspect. Google has now said, in advance, that a separate series of creator-focused changes will arrive across the year. Some are already done. The rest come with no dates, and nothing in the note suggests each will be announced. That weakens the link between when something moved and what moved it.

So how should a company think about cause when it has been told some causes will not be labeled?

Attribute to sources, not dates

My answer is to shift the question from timing to composition. Instead of asking whether the March update helped or hurt, ask which kinds of pages gained or lost room on the results for your name.

That matters here because of the word “creators.” Google has not defined it in this note, so any reading is partly a guess. For most companies, though, creator content about them means reviewers, independent bloggers, newsletter writers, forum regulars and video makers. If Google spends the year surfacing more of that, the first page for a brand could slowly tilt toward individual voices and away from the mix of corporate pages, news and reference sites that dominates many brand results.

A tilt like that would not look like a dramatic drop. It would look like one more personal review in position six this month, and a creator’s explainer replacing a trade article the next. A team tracking positions by date would see noise. A team tracking source types would see a trend.

What to do this week

Very little, in terms of reaction. The rollout has roughly ten days to run, and anyone naming winners and losers on day four is guessing. But it is a good week to add one column to whatever snapshot process you use: the type of source in each position. Own site, news, reference, review platform, forum, individual creator.

It is also worth knowing who the creators in your category are, and whether what they say about you is accurate. Not to manage them, which rarely works and often backfires, but because their pages may increasingly be what people see first.

Google’s standing advice is to make content for people rather than for rankings, a point I made in 2023 about performance theater. The March note adds a quiet corollary. The people writing about you count as content too, and Google has just said it intends to show more of them.
