A core update is a broad change to Google's ranking systems, and a fall in traffic that lines up with one feels like a verdict on your site. It is not necessarily a penalty. Google's page on core updates and your website says most sites do not need to worry about them and may not even notice one, and it sets out a specific process for those who see a change in traffic.
Step 1: Confirm the Update Has Finished
Google tells site owners to check the Search Status Dashboard and note the start and end dates of the update. Rollouts can take days or weeks, and rankings move during that time. Analysing your numbers before the rollout ends mixes in movement that has not settled.
Step 2: Compare the Right Dates
Google recommends waiting at least a full week after the update completes before analysing your site in Search Console. After that week, compare it with a week before the update started rolling out. Comparing days inside the rollout window, or comparing against an unusual week such as a holiday, gives misleading answers.
Step 3: See How Big the Drop Is
Look at your top pages and queries and how their positions changed. Google distinguishes between small and large drops. A small drop, such as moving from position 2 to position 4, does not call for drastic action, and Google advises avoiding changes to content that is already performing well. A large drop, such as moving from position 4 to position 29, deserves a deeper assessment.
Step 4: Check It Really Is the Update
Many traffic drops that coincide with an update have another cause: a tracking error, a site change, seasonality, a manual action or a technical fault. Work through our organic traffic drop diagnosis first, so you do not rewrite content to fix a problem that is actually a broken redirect.
Step 5: Assess the Content Honestly
For a large, update-linked drop, Google points owners to its guidance on helpful, reliable, people-first content. Ask the plain questions. Does the page answer the search better than the pages now above it? Is it original, or a summary of what others say? Is the information accurate and current? Does it show real experience and expertise? Is the page there for readers, or just for search engines?
Compare your affected pages with those that now rank above them. Look for differences in depth, freshness, clarity and how well they match what searchers want, not just keyword use.
What Not to Do
Google's guidance says to avoid quick-fix changes, such as removing some page element because you heard it was bad for SEO. Also avoid rewriting the whole site at once, buying links, or deleting content without a reason. Those moves rarely address the cause, and they make it harder to see what is working.
What to Do Instead
Pick the pages that lost the most traffic and matter most to the business, and improve them substantially: better answers, up-to-date facts, clearer structure, original examples or data, and removal of padding. Where several thin pages cover the same topic, consider combining them into one strong page. Keep a log of what you changed and when.
How Long Does Recovery Take?
Google notes that improvements can take effect between core updates, since it makes smaller updates continually, but that if you have not seen any effect after a few months, the next core update may be when it shows. Recovery is not guaranteed, and some pages that fall are simply outranked by better ones. Plan for months, not days.
Other Types of Update and Action
Core updates differ from spam updates, which target specific violations of Google's spam policies, and from manual actions, which are applied to a site by a human reviewer and appear in Search Console with instructions. If you have a manual action, follow the instructions in that report instead of this guide.
Reporting to a Client or Your Boss
Present the facts: the dates, the size of the drop, which pages and queries changed, and the plan. Avoid blaming the update or promising a recovery date. Our guide to measuring SEO ROI helps you show the impact in business terms.
Frequently Asked Questions About Core Updates
Is a core update a penalty? No. Google describes core updates as changes to how it assesses content, so pages can rise or fall without any rule being broken, unlike a manual action.
How long should I wait before analysing a core update drop? Google recommends waiting until the update finishes and then at least a full week before comparing your data.
Can I recover from a core update? Often you can by substantially improving the affected pages, but there is no guarantee and results may not show until a later update.
Getting Started
Write down the update's start and end dates, wait the recommended week, and compare that week with the one before the rollout began. Then decide whether the drop is small or large before changing anything.
