What Is a Google Core Update?

A core update is a wide spread update to Google’s search ranking algorithms. A core update can affect a wide range of different ranking signals, and it is not designed to target specific signals or to affect a certain subset of web sites. Google’s goal with a core update is to improve how the search algorithms determine the relevance of pages for different queries.

A core update is very different from other updates such as spam updates or product review updates. A core update affects almost every industry and every type of website whereas spam updates and product review updates are typically focused on improving how Google ranks sites that have been affected by spam in their product reviews.

Keep in mind that a decline in rankings after a Core Update does not automatically mean that Google has “penalized” a website. Rather, in comparison to other competing websites, Google’s algorithms have probably evaluated the respective websites and concluded that other websites are more useful, so they are ranked higher in the search results.
What Should You Review After the Rollout?

Now that your rankings have stopped dropping and have started to stabilize it’s time to review your site’s performance after the update.

Review Keyword Rankings

First, look at the previous ranking for your important keywords as compared to your current ranking. Check for big increases and big decreases in ranking.

Note whether there’s been a long-term trend rather than focusing on the ups and downs during the update’s release.

On your website you can check the organic traffic in your Google Analytics account. Here you can see whether the changes in your rankings have been positive or negative. You must make a distinction between long-term trends and the fluctuations that can occur in the days after a core update. For example check the landing pages, traffic by content categories and traffic on conversion-related pages and in general your search visibility.

Pay attention to:

• Landing page performance
• Traffic by content category
• Changes in conversion-related pages
• Overall search visibility

Examine Google Search Console Data

Also in Google Search Console you can see how your website performed in the update.

Review metrics such as:

• Total impressions
• Clicks
• Average position
• Top-performing queries
• Pages gaining or losing visibility

Search for patterns of change for individual pages on your site from the weeks before the update to the weeks after the update in Search Console data.
Evaluate Competitor Performance

The core update likely to have affected your website is part of a larger core update affecting the whole industry, not just your site.

If you see similar ranking fluctuations for competitors then fluctuations in your rankings are likely a result of broader algorithm updates rather than site specific issues. Competitor benchmarking is a powerful tool in helping to understand and context rank movements.

Also when measuring yourself against your competitors you get a better view of the effects of a core update.

Best Practices After a Core Update

Hold off on making changes for a week or two and then you can make changes based on the new signals. Instead of going into emergency mode and making a bunch of changes on your site as soon as your rankings drop after a core update has completed, wait a bit and then make changes on your site based on the new signals that Google’s updated algorithms have brought to light.

• Instead, focus on long-term improvements.
• Continue Creating High-Quality Content

Google continues to prioritize content that demonstrates:

• Experience
• Expertise
• Authoritativeness
• Trustworthiness (E-E-A-T)

More long-term-focused is to keep publishing lots of high-quality content that shows Experience, Expertise, Authoritativeness and Trustworthiness (E-E-A-T).

Improve Existing Content

If certain pages on your site have dropped in ranking it would be wise to review them to see if you can improve them.

Consider whether they:

• Fully answer user intent
• Offer unique value
• Include current and accurate information
• Demonstrate subject matter expertise
• Provide a better experience than competing pages

Instead of creating a lot of new content and trying to get it to rank in search, improve your existing pages to be the very best they can be for users.

Avoid Drastic Website Changes

Wait for the dust to settle and look at your full data after rankings have stabilized before you make any big changes for SEO after a core update.

Only make changes to your SEO after your rankings have stopped changing and you have looked at least looked at all of your data to make the best of any changes you make.

What Comes Next?

Core updates will be released by Google several times a year. As with every core update the impact on individual websites can vary. Some might experience immediate changes, others might not notice anything at first but will have changed later as Google’s processing system is further fine-tuned to deliver the best possible search results.

Some sites may see immediate changes to their rankings, while others may experience slow, positive or negative change over weeks as Google continues to fine-tune how pages are ranked in search results.

The June 2025 Core Update was likely the last major update for 2025 and will need to be monitored for effects weeks after the update has completed as Google’s ranking algorithms continue to fine-tune search results for best user experience.

Final Thoughts

As we have now confirmed that the Google June 2025 Core Update has completed, you can now review the post update SEO performance of your site and that of your competitors using the update stable post update data.
