Google Search is constantly changing.
Every day, Google makes changes to its search systems, ranking systems, interfaces, and experiments. Most of these changes are small and may never be noticed by website owners. But several times a year, Google releases larger updates that can cause significant changes in search rankings and organic traffic.
These are commonly known as Google algorithm updates.
For SEO professionals, publishers, businesses, and website owners, understanding these updates is important because a major update can change which pages appear prominently in Google Search.
In this guide, we’ll explain what Google algorithm updates are, the difference between core and spam updates, the major updates in recent years, what changed in 2026, and what you should do if your website loses rankings or traffic.
What Are Google Algorithm Updates?
Google algorithm updates are changes Google makes to the systems and algorithms used to organize and rank information in Search.
Google doesn’t use one single algorithm to determine every search result. Search consists of multiple systems designed to understand queries, webpages, content quality, relevance, spam and many other signals.
Some changes are minor.
Others are broad enough to noticeably change search results.
Google officially refers to significant broad changes as core updates. Google says these updates are designed to improve its ability to show helpful and reliable results and are not intended to target individual websites or pages.
This distinction is important.
A ranking drop after a core update doesn’t automatically mean that Google has issued a penalty against your website.
Your page may simply have been reassessed relative to other pages that Google’s systems now consider more useful for a particular search.
How Often Does Google Update Its Algorithm?
Google Search changes constantly.
Most changes are not major public updates.
For website owners, it is more useful to distinguish between:
- Core updates
- Spam updates
- Ranking-system changes
- Discover updates
- Other search-system changes
- Smaller, ongoing updates
Google also says it continually makes smaller core updates that are not announced because they are not widely noticeable.
So, you should not assume that nothing is changing simply because Google has not announced a major update.
What Is a Google Core Update?
A Google algorithm updates core is a broad change to Google’s core search systems.
Google releases these updates several times a year.
Core updates are intended to improve the overall quality and usefulness of search results.
They aren’t designed to target a specific website, industry or individual page.
Think of a core update as Google changing how it evaluates and ranks webpages across a broad range of searches.
For example, imagine that Google previously considered Page A more useful than Page B.
After improving its systems, Google may determine that Page B provides a better answer for a particular query.
Page B may move up while Page A moves down.
That doesn’t necessarily mean Page A suddenly became “bad.”
It may mean that Google’s systems now have a different understanding of which result is more useful.
Google uses a similar analogy in its official core-update guidance.
Google Algorithm Updates vs Google Penalties
These terms are often confused.
A Google algorithm update is a change to Google’s search systems.
A manual action is different.
A manual action occurs when Google’s spam team determines that pages on a site violate Google’s spam policies.
A ranking decline following a core update does not automatically mean that your site received a penalty.
This is why checking Google Search Console and the Search Status Dashboard is important before making major changes.
Major Types of Google Algorithm Updates
Not every Google update has the same purpose.
1. Core Updates
Core updates broadly change Google’s ranking systems.
They can affect many types of queries and websites.
Google recommends focusing on whether your content is helpful, reliable and created primarily for people when evaluating a significant ranking decline.
2. Spam Updates
Spam updates improve Google’s systems for detecting and handling content that violates Search spam policies.
Spam-related systems can address practices such as:
- Scaled content abuse
- Expired domain abuse
- Site reputation abuse
- Keyword stuffing
- Cloaking
- Link spam
- Other manipulative practices
Spam updates are different from core updates because their primary purpose is related to identifying and combating spam.
3. Discover Updates
Google also makes updates specifically affecting Discover.
For example, Google’s February 2026 Discover Core Update was designed to improve Discover by showing more locally relevant content, reducing sensational and clickbait content, and surfacing more original, timely and in-depth content from sites with relevant expertise.
Discover traffic can therefore change even when your traditional Google Search rankings don’t change significantly.
Major Google Algorithm Updates in 2026
If you’re researching the latest Google algorithm updates, 2026 has already brought several significant changes.
February 2026 Discover Core Update
Google released the February 2026 Discover Core Update on February 5.
According to Google, the update focused on improving the Discover experience by:
- Increasing locally relevant content
- Reducing sensational content and clickbait
- Showing more original and timely content
- Improving the visibility of content from websites demonstrating expertise in a topic
The update was initially released to English-language users in the United States and was planned for expansion to other countries and languages.
For publishers that depend heavily on Discover, this update was particularly relevant.
March 2026 Spam Update
Google released a March 2026 spam update shortly before the March core update.
Search Engine Land reports that the March 2026 spam update rolled out on March 24 and completed on March 25.
This is a good example of why SEO professionals should check the timing of multiple updates when investigating traffic changes.
March 2026 Core Update
Google’s first major core update of 2026 began rolling out on March 27.
Search Engine Land reports that the rollout lasted approximately 12 days and completed in April.
The update was described as a regular update intended to better surface relevant and satisfying content.
For SEO professionals, the key takeaway wasn’t a single new “ranking factor.”
Instead, websites needed to evaluate the overall quality, usefulness and relevance of their content.
May 2026 Core Update
Google released another major core update on May 21, 2026.
Search Engine Land reported that this was the second Google core update of the year and that its rollout completed on June 2.
Because core updates can cause substantial ranking volatility, website owners should avoid making conclusions while an update is still rolling out.
Wait until the rollout is complete before conducting a detailed before-and-after analysis.
August 2026 Spam Update
Google also released an August 2026 spam update.
Search Engine Land reported that the update completed in approximately two and a half days.
Spam updates are especially relevant if a website relies on aggressive SEO tactics or contains content that may violate Google’s spam policies.
Google Algorithm Updates: Recent History
Understanding the history of Google updates helps explain how SEO has changed.
2025
Major confirmed updates included:
- March 2025 Core Update
- June 2025 Core Update
- August 2025 Spam Update
- December 2025 Core Update
Search Engine Land reports that the June 2025 core update took about 16 days to complete, while the December 2025 core update took approximately 18 days.
2024
Major updates included:
- March 2024 Core Update
- March 2024 Spam Updates
- June 2024 Spam Update
- August 2024 Core Update
- November 2024 Core Update
- December 2024 Core Update
- December 2024 Spam Update
The March 2024 changes were particularly significant because Google incorporated its Helpful Content system into its core ranking systems. Search Engine Land reported that the March update was also accompanied by new spam policies covering scaled content abuse, expired domain abuse and site reputation abuse.
2023
Important updates included:
- March 2023 Core Update
- August 2023 Core Update
- September 2023 Helpful Content Update
- October 2023 Core Update
- November 2023 Core Update
- Multiple reviews updates
These updates continued Google’s broader movement toward rewarding useful content and improving search quality.
Why Does Google Keep Updating Its Algorithm?
The internet is constantly changing.
New websites are created every day.
Existing websites publish new content.
Users change the way they search.
New technologies introduce new forms of content.
Spam techniques also evolve.
Google therefore needs to continuously improve its systems.
Google’s core-update documentation explains that its broad changes are designed to ensure Search continues to provide helpful and reliable results as the web and content evolve.
This is why there is no permanent SEO formula.
A strategy that works today may become less effective later.
How Google Algorithm Updates Affect Rankings
An algorithm update can lead to:
- Ranking increases
- Ranking decreases
- Traffic increases
- Traffic decreases
- Changes in featured results
- Changes in which pages rank
- Changes in Discover visibility
- Changes in impressions
- Changes in click-through rates
The impact isn’t necessarily the same across an entire website.
One section may gain visibility while another loses it.
One keyword may improve while another declines.
That’s why analyzing data at the page and query level is important.
How to Check If a Google Algorithm Update Affected Your Website
If your organic traffic suddenly changes, don’t immediately rewrite every page.
Follow a structured process.
Step 1: Check Google’s Update Status
First, check whether a confirmed update was running during the period when your traffic changed.
Google maintains information about its ranking updates, while Search Engine Land also maintains a historical timeline of major updates.
Step 2: Wait for the Rollout to Finish
Don’t make major decisions while an update is still rolling out.
Rankings can fluctuate during the rollout.
Google specifically recommends confirming that the core update has finished before analyzing the impact.
Step 3: Use Google Search Console
Open the Performance report and compare:
- Clicks
- Impressions
- CTR
- Average position
Look at the data by:
- Query
- Page
- Country
- Search type
- Device
Google recommends comparing the period after a core update with the period before the update once the rollout has completed.
Step 4: Identify the Pages That Lost Visibility
Don’t assume the entire website has a problem.
Find the specific pages that experienced the largest declines.
Then ask:
- Is the content still accurate?
- Does it fully satisfy search intent?
- Is the page original?
- Does it provide first-hand value?
- Is it better or worse than competing results?
- Does the page demonstrate appropriate expertise?
- Is the information outdated?
- Are there technical issues?
What Should You Do After a Google Core Update?
This is where many website owners make mistakes.
They see a traffic drop and immediately:
- Delete pages
- Change keywords
- Rewrite titles
- Remove sections
- Build hundreds of backlinks
- Change URLs
- Add AI-generated content
- Buy links
These reactions can make things worse.
Google recommends avoiding quick fixes and instead focusing on meaningful, sustainable improvements that help users.
10 Ways to Prepare Your Website for Google Algorithm Updates
1. Create People-First Content
Your content should exist primarily to help people rather than manipulate rankings.
Ask:
Would someone find this page genuinely useful even if Google didn’t send traffic to it?
If the answer is no, rethink the content.
2. Match Search Intent
Understand what users actually want.
If users want a tutorial, don’t create a thin promotional page.
If users want a comparison, don’t provide only a definition.
If users want a local service, make relevant local information easy to find.
3. Add Original Value
Don’t simply rewrite what the top 10 results already say.
Add:
- Original examples
- Data
- Research
- Expert insights
- First-hand experience
- Case studies
- Screenshots
- Practical frameworks
Google’s 2026 guidance for generative AI features also emphasizes the importance of valuable, unique, non-commodity content.
4. Keep Important Content Updated
Review pages that depend on changing information.
Update:
- Statistics
- Product information
- Pricing
- Software features
- Industry trends
- Regulations
- Dates
- Screenshots
But only update information when there is something meaningful to change.
5. Improve Technical SEO
Check:
- Crawling
- Indexing
- Robots.txt
- XML sitemap
- Canonical URLs
- Redirects
- Broken links
- Mobile usability
- Page speed
- HTTPS
Good content cannot reach its full potential if search engines can’t properly access or understand it.
6. Strengthen Internal Linking
Connect related pages.
Internal links can help users discover additional resources and help Google understand the structure and relationships within your website.
Use descriptive anchor text naturally.
7. Earn Relevant Backlinks
Focus on earning links through genuinely useful resources.
Good opportunities include:
- Original research
- Industry reports
- Data studies
- Tools
- Expert guides
- Digital PR
- Useful resources
Avoid link schemes designed primarily to manipulate rankings.
8. Demonstrate Experience and Expertise
Make it clear who created the content and why they are qualified to discuss the subject when that context matters.
Useful elements can include:
- Author information
- Experience
- Sources
- References
- Case studies
- First-hand examples
Trust matters especially for topics where incorrect information could significantly affect users.
9. Avoid Search Spam
Don’t use tactics designed to manipulate Google’s ranking systems.
Examples include:
- Keyword stuffing
- Cloaking
- Link spam
- Scaled content abuse
- Expired domain abuse
- Site reputation abuse
Google’s spam policies apply across its Search experiences, including generative AI responses.
10. Monitor Search Console Regularly
Don’t wait for an algorithm update to check your SEO performance.
Monitor your website regularly.
This makes it easier to distinguish:
normal ranking fluctuations
from:
significant performance changes.
Does AI Content Cause Google Rankings to Drop?
This is one of the most common questions in 2026.
The answer isn’t simply “AI content = penalty.”
Google’s focus is on the quality and purpose of content, not merely whether a particular tool was used to create it.
The bigger problem is publishing content that is:
- Generic
- Repetitive
- Inaccurate
- Unoriginal
- Created primarily to manipulate rankings
- Produced at scale without meaningful value
Google’s 2026 generative-AI guidance emphasizes providing valuable, unique, non-commodity content and confirms that established SEO practices remain foundational for Google’s generative AI search features.
So, if AI is used during content production, the final result should still be accurate, useful, original and genuinely valuable to the reader.
Do Google Algorithm Updates Affect AI Overviews?
Google’s search experience now includes generative AI features such as AI Overviews and AI Mode.
Google published new guidance in May 2026 explaining how website owners can optimize for generative AI features.
Importantly, Google says existing SEO fundamentals remain relevant and foundational for success in these experiences. It also emphasizes valuable and unique content.
This means businesses shouldn’t abandon traditional SEO and chase every new AI optimization acronym.
Strong fundamentals still matter:
- Crawlable content
- Clear site structure
- Relevant information
- Useful pages
- Strong technical SEO
- Original value
- Appropriate structured data
- Good user experience
Do You Need to Wait for the Next Google Algorithm Update to Recover?
Not necessarily.
Google’s current documentation explicitly says that it continuously makes smaller updates to its search algorithms, including smaller core updates that aren’t announced.
So, if you improve your website, you don’t always have to wait for another major core update before seeing potential changes.
However, improvements may take time to be reflected.
Google notes that some changes can take days to show an effect, while broader improvements may take several months for its systems to recognize and confirm.
There is also no guarantee that a particular change will result in higher rankings.
Common Google Algorithm Update Myths
Myth 1: Every ranking drop is a Google penalty
False.
A core update can change rankings without your website receiving a manual penalty.
Myth 2: You need to make changes immediately after every update
Not necessarily.
First, identify what changed and whether the change is meaningful.
Google recommends avoiding quick fixes.
Myth 3: One ranking factor controls everything
No.
Google Search uses many systems and signals.
There isn’t one universal factor that determines every ranking.
Myth 4: Algorithm updates happen only a few times a year
False.
Major announced updates are only part of the picture.
Google continuously makes smaller changes to its search systems.
Myth 5: Every old article should be deleted
Not necessarily.
Google recommends considering content deletion as a last resort when content cannot be improved or salvaged.

Final Thoughts
Google algorithm updates are a normal part of SEO.
Instead of trying to predict Google’s next update or find a shortcut to avoid ranking fluctuations, build a website that consistently provides useful, trustworthy and relevant information.
The major changes seen in recent years show a continuing emphasis on useful content, spam prevention, quality and better understanding of what users need. In 2026, Google is also expanding generative AI features in Search while continuing to emphasize established SEO fundamentals.
If your rankings decline after an update, don’t immediately assume that your website has been penalized.
Check the data.
Wait for the update to finish.
Identify the pages and queries affected.
Then improve the underlying content and user experience rather than applying a quick SEO fix.
The goal isn’t to “beat” Google’s algorithm.
The goal is to build a website that remains useful even as Google’s algorithm evolves.
