Google Core Updates can cause significant changes to search rankings, organic traffic and visibility. For businesses that rely on Google Search to generate leads, sales and enquiries, a sudden ranking drop can understandably be concerning.
Google makes broad changes to its search algorithms and ranking systems several times a year. These Google Core Updates are designed to improve the overall quality and relevance of search results rather than target specific websites or individual URLs.
That means a page can lose visibility even when it has not received a penalty or committed a technical SEO error. Google may simply have changed how it evaluates content, meaning other pages are now considered more relevant or useful for particular searches.
For businesses, the important thing is not to panic or make quick changes based on a few days of data.
Instead, look at the bigger picture.
At DNRG, we monitor ranking changes, organic traffic, Search Console data and wider SEO performance to understand what is actually happening before recommending changes. This allows businesses to respond to algorithm updates strategically rather than reacting to every fluctuation.
What Is a Google Core Update?
A Google Core Update is a broad change to Google’s core search algorithms and ranking systems.
Google regularly updates how its search engine evaluates and ranks websites. Some changes are relatively small and may go unnoticed, while a broad core update can result in noticeable changes across search results and multiple industries.
Google explains that core updates are designed to improve how its systems assess content overall. They are not intended to target individual websites or specific pages.
One way to think about a core update is that Google is changing how it assesses the pages competing for important queries: a page that previously ranked highly may move down because another page is now considered a stronger resource.
That does not necessarily mean the page that moved down is “bad”. It may simply mean that Google’s ranking systems now have a different understanding of what represents the most useful result for that search intent.
Core Updates vs Other Google Algorithm Updates
Not every Google algorithm update is a core update.
Google makes many different types of changes to its search systems, including:
- Core updates: broad changes to Google’s ranking systems.
- Spam updates: changes designed to improve the detection and handling of spam.
- Search feature updates: changes to how features such as featured snippets and AI Overviews appear.
- Smaller ranking changes: ongoing improvements that may not be formally announced.
- Technical changes: updates affecting how Google crawls, processes or displays websites.
This distinction matters when analysing a ranking change.
A drop that happens during a core update should not automatically be attributed to the core update itself. Other algorithm updates, technical issues, competitor activity, seasonality and changes in search behaviour can all influence performance.
The Latest Google Core Updates
Google’s ranking systems are continually evolving, but confirmed core updates provide useful reference points when analysing major changes in search performance.
March 2026 Core Update
The March 2026 core update began rolling out on 27 March 2026 and completed its rollout after approximately 12 days. Google’s official Search Status Dashboard records it as a confirmed core update.
As with other broad core updates, the March update should not be interpreted as a penalty aimed at particular websites.
If a website experienced a ranking drop during the March 2026 core update, the appropriate response is to analyse the pages and queries affected rather than assuming that a single technical issue caused the decline.
May 2026 Core Update
The May 2026 core update began on 21 May 2026 and completed its rollout after approximately 12 days. Google’s Search Status Dashboard records the rollout as lasting 11 days and 21 hours.
If your website experienced changes during the May 2026 core update, compare performance before, during and after the rollout.
Avoid drawing conclusions while an update is still rolling out.
Google has stated that ranking changes can continue to settle as a core update progresses, meaning data collected halfway through the rollout may not represent the final outcome.
How Do Google Core Updates Work?
Google’s search algorithms use numerous systems to determine which pages should appear for a particular search.
These systems consider whether content is relevant, useful and capable of satisfying the user’s search intent.
A core update can change how Google’s systems evaluate these signals.
For example, Google may improve its ability to understand whether a page genuinely demonstrates expertise on a subject, whether the content provides useful information or whether another page better satisfies the searcher’s needs.
This means rankings can change even when a website owner has made no changes.
Google describes core updates as broad improvements to its search systems rather than actions against individual websites.
Why Do Rankings Change After a Core Update?
There are several possible reasons.
A page might have:
- Become less relevant to the search intent.
- Been overtaken by a stronger resource.
- Been affected by changes in how Google evaluates content quality.
- Lost visibility because competitors have improved their content.
- Become less competitive as search results evolve.
- Been affected by changes to other search features.
- Experienced technical SEO problems at the same time as the update.
It is therefore important not to assume that a ranking drop means Google has identified a specific fault.
The change may be relative.
Your website might have stayed exactly the same while another site improved.
What Should You Do If Your Rankings Drop?
A ranking drop immediately after a core update can tempt businesses to make major changes to their website, rewrite pages or remove entire sections of content.
That can make the situation worse.
Google itself recommends taking a broader view when assessing the impact of a core update and warns against making changes based solely on individual ranking movements.
Instead, start by establishing whether there has actually been a sustained drop.
1. Wait Until the Update Has Finished Rolling Out
Don’t draw conclusions while a confirmed core update is still rolling out.
Google’s updates can take days or weeks to complete, and rankings can fluctuate throughout the process.
Once the rollout is complete, compare performance against a suitable historical period.
This gives you much more reliable data than looking at rankings on a single day.
2. Analyse Google Search Console Data
Google Search Console is one of the most valuable tools for understanding changes in organic search performance.
Look at:
- Clicks.
- Impressions.
- Click-through rate.
- Average position.
- Top queries.
- Top pages.
- Important landing pages.
- Search appearance.
- Changes in visibility.
Compare the period before the update with the period after it.
The objective is to establish whether the change affected:
- The entire website.
- Specific sections.
- Particular product pages.
- Individual URLs.
- Specific search queries.
- Certain search intents.
- Particular locations or devices.
This distinction is important.
A small decline in a handful of keywords is very different from a large drop affecting an entire section of the website.
3. Look Beyond Average Position
Average position can be useful, but it should not be analysed in isolation.
For example, a page may move from position three to position five while still receiving similar traffic.
Likewise, a page can maintain a similar average position while receiving fewer clicks because search results now contain additional features.
These could include:
- Featured snippets.
- AI Overviews.
- Image results.
- Video results.
- Shopping results.
- Local results.
- Other search features.
Changes to the search results themselves can therefore influence click-through rate even when traditional rankings appear relatively stable.
Check Your Top Pages
If organic traffic has fallen, identify which pages have lost the most visibility.
Look at your top-performing pages before the update and compare their performance afterwards.
Ask:
- Which pages lost clicks?
- Which pages lost impressions?
- Which pages experienced a ranking drop?
- Which queries changed?
- Has search intent changed?
- Are competitors now appearing above you?
- Has Google surfaced different types of content?
- Are important pages still internally linked?
- Has the content become outdated?
Review Your Content Quality
Content quality is one of the most important areas to investigate after a core update.
Google’s guidance consistently emphasises helpful, reliable and people-first content.
That means content should demonstrate genuine knowledge and provide information that is useful to the person reading it.
Consider whether each important page:
- Clearly answers the user’s question.
- Satisfies the relevant search intent.
- Provides genuinely useful information.
- Demonstrates clear expertise.
- Adds something beyond what is already available elsewhere.
- Is accurate and up to date.
- Provides sufficient depth.
- Avoids unnecessary repetition.
- Is written for people rather than search engines.
This is particularly important for websites with large volumes of low-quality content.
Creating tens of thousands of pages does not automatically create SEO value.
In many cases, a smaller number of genuinely useful pages can provide a stronger foundation than a website filled with thin, repetitive or low-value content.
Don’t Delete Content Just Because It Lost Rankings
A ranking drop does not automatically mean that a page should be deleted.
Before removing content, understand why the page exists and whether it provides value.
Google’s guidance specifically notes that deleting entire sections of a website can be a sign that those sections were created primarily for search engines rather than people.
Instead, consider whether the page can be improved.
Could it provide a clearer answer?
Could it demonstrate stronger expertise?
Could it better satisfy the search intent?
Could it include more useful examples?
Could it be consolidated with another page?
These questions are much more valuable than simply asking whether a page is ranking.
Review Search Intent
Search intent can change over time.
Google’s ranking systems are designed to understand what users are trying to find and surface results that satisfy that need.
For example, someone searching for a product may want to see product pages, while someone searching for “how does X work?” may expect an educational guide.
If your page no longer matches the type of result users expect, it may become less competitive.
Review the current search results for important queries and look at what Google is surfacing.
Are the top results:
- Guides?
- Product pages?
- Service pages?
- Comparison articles?
- Videos?
- Reviews?
- Original research?
- Local businesses?
The search results can provide useful insight into what Google currently believes will satisfy the query.
Check Your Internal Links
Internal links help Google understand the relationship between pages and discover important content.
A core update can be a good opportunity to review your internal linking structure.
Make sure important pages are supported by relevant links from other authoritative pages on the site.
Look at:
- Internal link volume.
- Relevant anchor text.
- Links from high-performing pages.
- Links to important commercial pages.
- Orphaned pages.
- Links between related content.
Internal linking is unlikely to be the sole explanation for a major core update ranking change, but it remains an important part of a technically sound SEO strategy.
Check for Technical SEO Problems
Not every ranking drop is caused by an algorithm update.
Technical SEO problems can occur at the same time and create a decline in organic traffic.
Check for:
- Crawl errors.
- Indexing issues.
- Broken internal links.
- Incorrect canonical tags.
- Robots.txt problems.
- Noindex directives.
- Redirect issues.
- Mobile usability problems.
- Site speed problems.
- Core Web Vitals issues.
- Changes to important URLs.
Google Search Console can help identify some of these problems.
The key is to separate technical issues from broader ranking changes before making significant strategic decisions.
What About Core Web Vitals?
Core Web Vitals measure aspects of the user experience associated with loading performance, interactivity and visual stability.
They form part of Google’s wider page experience considerations, but businesses should not assume that a poor Core Web Vitals score automatically explains a significant core update ranking drop.
Technical SEO matters, but so do relevance, content quality, search intent and the overall usefulness of the page.
SEO performance needs to be assessed as a whole rather than reduced to one technical metric.
What About Link Spam and Manual Actions?
Core updates should also be distinguished from spam updates and manual actions.
Google regularly updates its systems for detecting spam, including practices such as link spam.
A link spam issue is therefore not automatically evidence of a core update problem.
Similarly, a manual action is different from an algorithmic ranking change.
If Google identifies a specific violation of its spam policies, a manual action may be applied to a website.
Google Search Console provides information about manual actions, so this should be checked when investigating a significant loss of visibility.
Should You Make Changes After a Core Update?
Yes, but changes should be based on evidence.
There is no universal “core update fix”.
Google’s guidance makes clear that there are no specific actions that guarantee recovery after a core update. Instead, website owners should focus on improving the overall quality and usefulness of their content.
Avoid quick fixes such as:
- Changing every title tag.
- Rewriting every page.
- Removing large sections of content.
- Adding keywords unnecessarily.
- Creating hundreds of new pages.
- Changing URLs without a clear reason.
- Building low-quality links.
- Making major technical changes without evidence.
Instead, identify where the biggest opportunities exist and prioritise improvements.
How Long Does It Take to Recover From a Core Update?
There is no fixed recovery period.
Google explains that some improvements can have an effect within days, while other changes may take several months for its systems to recognise and confirm that a website is consistently producing helpful, reliable, people-first content.
This is why sustained improvement is more important than trying to reverse a ranking drop overnight.
There may also be opportunities to improve rankings before the next confirmed core update, as Google continually makes smaller changes to its search algorithms and ranking systems.
How DNRG Responds to Google Core Updates
At DNRG, we don’t treat every Google algorithm update as a reason to immediately change a client’s SEO strategy.
The first step is understanding what actually happened.
We analyse:
- Google Search Console data.
- Organic traffic.
- Search rankings.
- Click-through rates.
- Average positions.
- Top-performing pages.
- Pages that have lost visibility.
- Important search queries.
- Search intent.
- Competitor performance.
- Technical SEO issues.
- Internal linking.
- Content quality.
- Wider search features.
This helps establish whether a change is isolated to a handful of URLs or represents a broader shift across the website.
From there, improvements can be prioritised based on evidence.
For example, if an important product page has lost visibility because competing pages now provide more comprehensive information, the solution may be to improve the content and demonstrate clearer expertise.
If an entire section has lost organic traffic, a wider content and site structure review may be necessary.
And if rankings have dropped alongside crawl errors or indexing problems, the priority may be technical SEO.
The important thing is to understand the bigger picture before acting.
What Should You Do Before the Next Core Update?
The best time to prepare for a Google Core Update is before one happens.
Rather than waiting for a ranking drop, businesses should continually improve their websites.
Focus on:
Create genuinely useful content
Develop content that demonstrates genuine knowledge and provides useful answers to important queries.
Understand search intent
Make sure every important page matches what users actually want when they search.
Improve content quality
Review older content regularly and update pages where information has become outdated or incomplete.
Strengthen internal links
Help users and search engines discover your most important pages.
Resolve technical SEO problems
Monitor crawl errors, indexing issues, Core Web Vitals and other technical factors.
Monitor Search Console
Use Search Console data to establish a performance baseline and identify changes early.
Track competitors
Search results are competitive. If other sites improve, your relative position can change even when your own website has not.
Monitor the wider search landscape
Google Search continues to evolve, including the introduction and expansion of features such as AI Overviews and AI Mode. Google has continued to develop these experiences during 2026, while also emphasising the importance of unique, valuable content and established SEO best practices.
Google Core Updates: The Bottom Line
Google Core Updates are a normal part of how search engines evolve.
A confirmed core update can result in major changes to search results, rankings and organic traffic, but a ranking drop does not automatically mean that a website has been penalised.
The most effective response is to step back and analyse the data.
Look at Search Console. Review your top pages. Analyse search intent. Compare competitors. Check technical SEO. Assess content quality. Look at internal links and consider whether the current search results are rewarding a different type of resource.
Most importantly, avoid chasing quick fixes.
Google’s search algorithms will continue to change, and the next core update will inevitably bring further changes. The businesses best positioned to maintain visibility are those that continually invest in useful, high-quality content, strong technical foundations and a website that genuinely satisfies its users.
At DNRG, we monitor Google algorithm updates and their impact on our clients’ organic performance, using data to identify meaningful changes and prioritise the right actions.
Because the goal isn’t simply to recover from the latest Google Core Update it’s to build a website that continues to perform as search evolves.
