A website loses rankings after a Google Core Update because the algorithm has recalibrated to prioritise content that demonstrates superior E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), better matches search intent, or offers higher, human-centric quality than before.
Core updates often demote sites with thin, over optimised, or outdated content, or sites that lack original insights or first-hand experience.
The good news is that this is diagnosable and fixable. This guide covers exactly why it happens, which signals Google is weighting more heavily, and the steps to recover before the next core update rolls out.
What are Google Core Updates?
A Google Core Update is a broad change to how Google evaluates content quality across every indexed page on the web.
Unlike spam updates, which target specific violations such as link buying or scaled content abuse, core updates are not penalties. They recalibrate the entire ranking system.
When your site loses rankings after a core update, it does not mean you broke a rule. It means Google’s new quality bar is higher than where your content currently sits.
How many times a year does Google update its search algorithm?
Google updates its search algorithm thousands of times annually, averaging over 10 daily changes. While most are minor, unannounced tweaks, Google typically releases several major core updates, spam updates, and reviews updates, totalling 4 to 8 significant, wide-reaching updates per year.
Broad core updates are not the only updates to track. Google also releases spam updates, which target manipulative practices, and feature specific updates that affect surfaces like Google Discover. Each type can move rankings independently.
If your traffic dropped, always cross-reference the date against the Search Status Dashboard before drawing any conclusions. Not every ranking change is a core update.
How significant are Google Core Updates?
Google Core Updates are highly significant, often causing major, industry-wide volatility in search rankings and organic traffic, sometimes shifting top ranking sites to page four overnight.
The December 2025 Core Update was the most disruptive since March 2024, causing major ranking shifts across virtually every industry. Based on analysis by ALM Corp covering 847 affected websites:
- 71% of affiliate sites saw significant ranking drop
- 67% of health and YMYL content was affected
- 52% of e-commerce sites lost visibility
- 15% of top-10 pages dropped entirely out of the top 100
- 23% more traffic loss for pages with LCP above 3 seconds vs faster competitors
These figures are not outliers from a single bad update. They reflect the direction Google has been moving consistently across every major update since 2024: raising the bar on content quality, demonstrated expertise, and page experience.
The most recent Google Core Updates: what changed and when
| Google Core Update | Rollout period | Main focus |
|---|---|---|
| March 2026 | 27 Mar 2026, ongoing | First broad core update of 2026. Focused on surfacing relevant, satisfying content from all types of sites. Rollout expected to take up to two weeks. |
| December 2025 | 11 to 29 Dec 2025 | Most disruptive since March 2024. E-E-A-T, Core Web Vitals, and content freshness became key differentiators. Affiliate sites hit hardest at 71%, health at 67%, e-commerce at 52%. |
| June 2025 | 30 Jun to 17 Jul 2025 | Refined how Google reads existing quality signals. Sites coasting on historically strong signals without maintaining content quality started losing ground. |
| March 2025 | 13 to 27 Mar 2025 | Content authenticity and intent alignment. First update to deprioritise content lacking first-hand experience, even when technically accurate. |
| December 2024 | 12 to 18 Dec 2024 | Arrived just 8 days after the November update. Fastest rollout on record at 6 days, but more volatile than the update before it. |
| November 2024 | 11 Nov to 5 Dec 2024 | Content relevance and user intent alignment. Lower volatility than previous updates. |
| August 2024 | 15 Aug to 3 Sep 2024 | Rewarding genuinely helpful content. Google explicitly responded to feedback from small and independent site creators who felt disadvantaged by previous updates. |
| March 2024 | 5 Mar to 19 Apr 2024 | Multiple core systems updated simultaneously. Targeted AI-generated and unoriginal content at scale. Longest rollout on record at 45 days. |
Why did the Google Core Update affect your site specifically?
Core updates do not punish past behaviour. They raise the quality bar.
Sites that sat just above the old threshold can find themselves below the new one, even if nothing on their site changed.
Based on patterns we observe consistently across updates, sites that lose rankings most severely share one or more of these characteristics.
Failure to meet E-E-A-T standards
No named author. No first-hand experience. No reference to real outcomes. Google is increasingly good at detecting the difference between theory and practice, and content that lacks clear signals of genuine expertise is consistently deprioritised. In 2026, demonstrating authority also means being the source that AI models choose to cite, which requires a different approach to how you structure and signal expertise across your content.
Content written for search engines, not people
Optimised around keywords and structure, but thin on genuine depth, original data, or practitioner insight. Google’s systems have become significantly better at identifying content built to rank rather than built to help.
Over-optimisation and keyword cannibalism
Too many pages targeting the same or very similar keywords, or content that forces keywords unnaturally, makes it harder for Google to determine which page deserves to rank. The result is that none of them do particularly well. If you have multiple articles covering the same topic without clear differentiation, that is worth addressing as part of any recovery audit.
Outdated content
Evergreen guides that have not been substantively updated: not just date-stamped, but actually improved with new information and current data.
Poor Core Web Vitals
Two metrics matter most here: Largest Contentful Paint (LCP), which measures how fast your main content loads, and Interaction to Next Paint (INP), which measures how quickly your page responds to user interactions. Pages that perform poorly on either consistently see greater traffic loss than faster competitors with comparable content quality.
Thin topical authority
Publishing broadly across many topics without depth in any of them. A specialist who owns a niche will consistently outrank a generalist.
A note from our SEO team: In our experience, the sites that struggle most after core updates are not the ones doing something obviously wrong. They are the ones that built content strategies around what Google used to reward, without keeping pace with what Google increasingly demands: real expertise, demonstrated experience, and content that treats the reader as someone who deserves a complete answer. The update did not change what good content looks like. It just got better at identifying which pages actually deliver it.
Step one: confirm the cause before you act
Before changing anything, verify that a core update is actually responsible.
Check the Search Status Dashboard and match the rollout dates against your GA4 data. If impressions and clicks both fell together, you have lost rankings. If clicks dropped but impressions held, you have a click-through rate problem, which is a separate issue.
Also open Google Search Console and check the Manual Actions report. If Google has issued a manual penalty against your site, it will appear there with a description of the issue. A manual action requires a different response entirely and is not resolved by improving content quality alone.
If there is no manual action and the timing aligns with a confirmed core update rollout, you are dealing with an algorithmic change. Also check Semrush Sensor or Sistrix for your category. A 15% drop in a niche that saw 40% average volatility is very different from a 15% drop in a stable niche. Context matters before you act.
How to recover rankings after a Google Core Update
There is no single fix. Core updates evaluate your site holistically, so recovery requires improvement across content, E-E-A-T, and technical health at the same time.
1. Identify which pages lost rankings: Use Google Search Console filtered by impressions change over the update window. Prioritise the pages that drove the most traffic. These are your recovery targets.
2. Audit each page against whoever is outranking you: Open the pages now sitting in positions 1 to 3. Compare depth, original data, author credentials, and page speed. The gap you find is your brief.
3. Improve content depth, not just length: Do not pad. Add original insight: what you have tested, what the data shows, what a real outcome looked like. A 1,200-word article with genuine expertise will outperform a 3,000-word article that restates what is already publicly available.
4. Strengthen E-E-A-T signals: Add a named author with real credentials. Include first-hand experience in the body copy. Link to primary sources: Google’s own documentation, platform changelogs, or the relevant regulatory body.
5. Fix Core Web Vitals on affected pages: Run PageSpeed Insights using field data. Address both LCP and INP. A Largest Contentful Paint above 2.5 seconds or a poor INP score is likely contributing to your ranking gap, not just your user experience.
6. Consolidate cannibalising content: If multiple pages are competing for the same keyword, decide which one deserves to rank and consolidate the others into it. Thin pages targeting overlapping topics dilute your authority and confuse Google’s ability to rank you well for any of them.
7. Add a FAQ section with FAQPage schema: At least three question-and-answer pairs targeting People Also Ask queries. These are disproportionately likely to be cited by AI models and to win featured snippet positions.
8. Update internal linking to deprioritised pages: Pages that lost authority after the update can be stabilised by adding contextually relevant internal links from your stronger pages.
Recovery typically takes three to six months. Changes you make now need to be in place and indexed well before the next core update rolls out.
What not to do after a Google Core Update
Do not panic or make sudden, drastic SEO changes immediately after a Google Core Update. Avoid removing content, spammy link building, or changing meta tags within the first 2-3 weeks, as rankings often settle later. Instead, analyse data to debug issues, focusing on long-term user value.
- Do not submit a reconsideration request. Core updates are not manual actions, so reconsideration requests do not apply.
- Do not update article dates without changing the content. Google detects when content was actually modified, not just when the timestamp changed.
- Do not delete underperforming pages. Removing content damages topical authority. Improve them instead.
- Do not use AI to surface-rewrite content without adding genuine expertise. Shallow rewrites do not address the underlying quality gap.

Frequently asked questions
What are Google Core Updates?
Google Core Updates are broad changes to how Google evaluates content quality across every indexed page. They are not penalties. They represent Google raising or refining its quality bar, and they affect all websites in all categories globally.
How often does Google update its search algorithm?
Google releases broad core updates three to four times per year. Each one is announced publicly via the Search Status Dashboard. On top of these, Google makes thousands of smaller, unannounced changes throughout the year that can also shift rankings incrementally.
Does a Google Core Update mean my site has been penalised?
No. A rankings drop after a core update is not a manual penalty and does not mean your site violated any guidelines. It means other pages are currently judged as more relevant or authoritative. The path forward is improving content quality, not submitting a reconsideration request.
How long does recovery from a Google Core Update take?
Most sites see meaningful recovery between three and six months after implementing improvements. Sites in YMYL categories covering health, finance, and legal topics often take six to twelve months. Full recovery typically only becomes visible when the next broad core update rolls out.
What types of content are most at risk from Google Core Updates?
AI-generated content without expert oversight, thin affiliate pages, evergreen guides that have not been substantively updated, and pages that prioritise keyword density over user value. Health, finance, e-commerce, and affiliate content consistently see the highest impact rates across recent updates.
A Google Core Update is not the end of your rankings. It is a diagnosis.
The sites that recover fastest treat it as useful feedback: Google is telling you that other content is currently serving users better than yours.
Fix the content. Add the expertise. Improve the page speed. Then wait for the next update to confirm it.
