Google Core Updates: What to Do When the Algorithm Moves
Several times a year, Google deeply re-evaluates which results deserve each position — and rankings shake. A core update isn't a punishment and has no appeal: it's a reshuffle. What you do in the following weeks decides whether you come out stronger or make things worse by rushing.

Two to four times a year, Google announces a core update: a deep recalibration of its ranking systems that can move positions across every industry at once. For a few weeks, the SEO forums burn, the charts dance, and thousands of business owners open Analytics with a knot in their stomach.
Most of what gets done in those weeks — frantic changes, hiring "recovery experts", rewriting everything — makes things worse. This guide is the opposite protocol: understand what a core update is, diagnose with data whether and where it hit you, and respond with the actions that actually have a track record.
What a core update is (and isn't)
A core update doesn't chase offenders: it recalibrates how Google evaluates quality and relevance across the whole index. If your site drops, you didn't do anything "wrong" that can be point-fixed — other pages started being evaluated as better answers for those searches. That's why there's no appeal and no quick fix: there's competition. The distinction matters because the remedy for a real penalty — clean up and appeal — doesn't apply here; if you're unsure which of the two happened to you, that diagnosis has its own guide.
How to know if it hit you (with data, not panic)
- Confirm there was an update: Google announces them on its Search Status Dashboard. Without an official announcement, your drop is probably something else — technical, seasonal or competitive.
- Wait for it to finish: updates take one to two weeks to roll out, and positions oscillate meanwhile. Measuring mid-rollout is measuring smoke.
- Compare periods in Search Console: the four weeks after against the four before. Look for the pattern — did specific pages fall, or the whole site? Queries on one topic, or all of them?
- Look at who rose: search your lost terms and study the new leaders. What they have and you lack is the most honest diagnosis available.
If you dropped: the calm protocol
| Pattern | Likely reading | Action |
|---|---|---|
| Specific pages fell | That content stopped being the best answer | Genuinely improve them: depth, first-hand data, freshness |
| A whole topic fell | Insufficient topical authority against specialists | Reinforce the cluster: more quality pieces, better linking within the topic |
| The whole site fell evenly | Global quality signals: experience, trust, thin content | A full audit and an impact-ordered plan — not loose patches |
For the third case — the across-the-board drop — the right instrument is a serious audit, not a list of tricks. And in all three cases, the improvement that counts is substantive: content with real experience and your own data, not paragraphs reshuffled to "look better".
The questions Google itself publishes
What not to do
Real recovery: in cycles, not days
The honest expectation: substantial improvements you make today usually show up in the algorithm's next cycles — weeks or months — not the next day. Google has said explicitly that recovery from a core update may wait until the next one. It's frustrating, and it's also the best possible news: the game rewards sustained quality work, which is exactly what a small business can do better than an inattentive giant. That's the underlying thesis of the whole SEO strategy — and the reason well-built websites tend to gain positions with each update rather than lose them.
Frequently asked questions
How often do core updates happen?
Google typically releases two to four core updates a year, officially announced, plus continuous minor adjustments that aren't. Each rollout takes one to two weeks. They can't be predicted, and organising around their dates is pointless: the right preparation is the same all year round.
My traffic dropped but no update was announced — what is it?
Almost certainly something else: a technical issue (check indexing and errors in Search Console), your industry's seasonality, a competitor that improved, or changes in how Google displays results (more ads, new modules). Diagnosis starts in Search Console comparing periods — and ruling out the technical before theorising about algorithms.
I went UP with the update — should I do anything?
First, don't touch what's working. Then use the signal: the update confirmed your quality approach is on track, so document which pages rose and do more of that. And consolidate — a won position is defended with the same sustained work that earned it.
Do core updates hit small sites the same way?
They affect everyone, but the pattern favours specialisation: recent updates tend to reward demonstrable experience and topical depth — terrain where a small specialist beats a big generalist. A focused site with first-hand content in its niche usually comes out better than the giant aggregators that cover everything and know nothing.
