What is a Google Core Update?

A Google Core Update is a broad change to Google’s ranking systems, used to evaluate the quality of content and relevance of websites across the web. 

Unlike narrower updates that focus on spam, product updates or reviews, core updates are designed to reward content that is seen as helpful, reliable and which satisfies the users search intent.

 

Why Does Google Update its Algorithms?

 

 

The internet is constantly changing, content that was useful a year ago may not be the best answer today. Search habits also change, and new sources and platforms such as video and social platforms are being used to find information.

To handle this, Google updates their ranking algorithm to understand what users are looking for and ensure that the most relevant and useful content is shown.

To keep up with this pace of change, Google’s algorithm looks at:

  • Relevance to the search query?
  • Whether a page matches the users search intent – are they looking to buy or just for more information?
  • Originality, versus duplicated or copied content
  • Topical authority and credible expertise
  • Pages include real, reliable first-hand experience
  • Local relevance versus generic, global content

A ranking shift does not mean a website has done anything wrong, it can simply mean another page now satisfies one of these factors better – post algorithm update.

This is why core updates can often be frustrating. There may be nothing wrong with a website, there could be no manual penalties, no technical errors and no other obvious issues. However, rankings can still change simply because Google has updated how it assesses the quality and relevance of websites across the internet.

 

When Was the May 2026 Core Update?

 

 

The update launched on May 21st 2026 and finished rolling out on June 2nd 2026.

Google gave only a brief announcement for the May update. Their accompanying LinkedIn post described it as “designed to better surface relevant, satisfying content for searchers from all types of sites”, with no other expected changes or guidance given. 

This suggests that the update wasn’t targeting any specific website types or on-page content, instead, it was a broad update.

 

Google 2026 Update Timeline

  • Launched – May 21, 2026
  • Completed – June 2, 2026 (11 days, 21 hours to)
  • Update Type – Broad search algorithm update
  • Reach – All regions, languages and content types

 

 What Made the May Core Update Different?

The launch of the May core update happened just 48 hours after Google’s I/O 2026 Conference, where Google unveiled a new Gemini-powered search box and a focus on continued AI-search results over traditional site links.

The combination of a new search box along with a core update could mean that it’s now harder to track the impact and effectiveness of both, since a core update would affect traditional organic rankings, and an AI-search box affects how those sites which are ranking are shown to users.

 

What Happened During the Rollout?

The 12-day rollout brought typical ranking volatility, with some sites seeing sharp drops while others recovered ground lost following the March update.

Search volatility is very common during a core update. Google rolls out changes across many different languages, regions and locations around the world, which can cause rankings to shift throughout the update process. This is why Google advises waiting a week until after the update is deployed to get a true reflection of the impact before making any changes.

Many third-party tracking tools also reported high levels of search volatility. 

SEMRush reported high levels of search volatility throughout the rollout period. Their Sensor platform checks the search rankings for a fixed number of keywords daily, and measures how many have changed at the end of each day. 

The high score shown above means that there was an increase in changes in rankings on those dates which occurred just before the update started and near the end of the update.

However, a week after the rollout finished, search volatility has stabilised.

 

What Changed after the May Update?

 

 

Whilst Google has not published exactly what the update was targeting, there have been reports and independent reviews carried out by SEO industry experts to identify common trends of the impact of the recent update.

 

Google is Rewarding Search Intent

One of the reporting findings from the May core update is the importance of search intent. It appears that Google is now placing greater emphasis on whether a page is the right type of result to show to a user for a particular search.

Research from Aleyda Solis, analysing SISTRIX visibility data between May 26th and June 2nd, found pages matching a user’s intent, location and expected result type gained visibility.

For example, local searches (a plumber, a petrol station, etc) now tend to favour local businesses, Google Business Profiles or map results over well-optimised national-facing pages. Searches for advice based on personal experience are also more elilely to surface from discussions than long-form articles.

 

The Importance of Local Search Relevance

Local relevance is rising in importance too.

Location-specific websites have seen a boost in search results over broader global domains. This includes websites improving in visibility when the information provided is from the user’s country, such as .co.uk served to users in the UK over global .com domains. 

For local-intent searches, a smaller, more relevant local business can now outrank a larger generic competitor.

All of this makes localised landing pages, reviews, up-to-date contact details, a complete Google Business Profile, and local citations and links increasingly important.

 

Content is Still King

Quality content remains essential, but quality not quantity. As more sites lean on AI for copy creation, generic and thin content is becoming common, and Google is rewarding content that genuinely benefits the user.

Instead, Google is placing greater emphasis on content that actually benefits the user. This could include aspects such as:

  • Original insights and first-hand experience
  • Clear explanations which are easy to follow
  • Expert opinion and trusted sources
  • Helpful examples and video walkthroughs
  • Accurate and up-to-date information
  • Detailed product or service information and guidance.
  • Clear answers to common questions such as FAQs

Content that simply repeats what already exists is unlikely to stand out and is more likely to drop in search results.

 

Recovery from the March Core Update

Some website owners who were affected by the March core update have reported improvements after the May update. 

Google is continually updating their search algorithm, and if your website gained visibility after May, it may be because Google has reassessed the content on your website as having more value, or that competitors have lost rankings within the search results.

 

How to Respond to the May 2026 Core Update

 

 

If your website has been affected by the May 2026 core update, the most important thing is not to panic. A drop in rankings does not mean your website has been penalised, it simply means that Google has reassessed how your page content and relevance compares to others in the search results.

If you suspect your site was impacted by the most recent update, Google recommends the following process.

 

Review Search Console Performance

Review which pages have declined in clicks and impressions within Google Search Console. You can also review which queries have dropped and by how much. This will help you understand whether the decline in performance is affecting your entire website or only specific sections of the site, such as blogs, product pages or local service pages.

Once you have a better understanding of which pages are affected and which keywords you have lost, search within Google for those search terms and observe:

  • Are new competitors outranking you?
  • Are there more local businesses ranking higher?
  • Are forums, videos or AI Overviews taking more visibility?

This can help give you a clearer understanding of if your page matches what Google believes users want.

 

Improve Content, Relevance and Trust Signals

For affected pages, compare your content against what now outranks it, is it useful? accurate? and current?

If not, then you may need to:

  • Update any outdated information, and include a timestamp saying when the page was updated if it is a blog or article
  • Add more useful content, guidance, FAQs which match the users search intent
  • Improve the structure of your page so that more relevant information is nearer the top of the page, rather than buried near the bottom
  • Strengthen internal links to spread authority across the domain and ensure that all pages are correctly crawled and indexed
  • Strengthen trust signals with clear contact details, author bio pages, accreditations, reviews and any awards won
  • Answer related questions and in different formats such as text and video
  • Remove thin, unnecessary or duplicate content

For local businesses: Keep your Google Business Profile complete and current, services, hours, accessibility information, and make sure your address and contact details match exactly across your site and other citations.

 

What the Latest Core Update Means for the Future of SEO

 

 

Google now includes AI overviews, video results, local business listings, discussions and forums, featured snippets and other search features within their results.

Google is becoming more selective about what kind of result to display in each search type. A page could be well written and full of useful content, however Google may still not class that type of page as the correct result to match a user’s search intent. Even large, popular websites may lose to a local website which is more relevant to the user.

To stay competitive, websites need more than optimisation, genuinely useful, expert, locally relevant and current content, written for the specific intent behind each search.
