Imagine your website suddenly loses a massive amount of visibility on Google - for seemingly no reason. Frustrating, isn't it? Welcome to the world of Google Core Updates. They come unannounced, can shake up rankings and often leave you at a loss. But don't worry - you're not at the mercy of it. There are ways to react, optimize and get back on top.
What is a core update anyway?
A core update is a comprehensive change to Google's central algorithm. It is not a penalty, but a readjustment of the evaluation criteria used to evaluate content on the web. The aim is to improve the quality of search results.
What you should know:
- Core updates happen several times a year.
- They often have a sector-specific or thematic impact.
- Even high-quality pages can be affected - without there being an "error".
Important: If you are affected, this is not necessarily due to poor quality, but because Google is setting new standards - for example in terms of topic authority, topicality or user signals.

What to do if your site is affected by the core update?
A loss of ranking is annoying - but also an opportunity to improve. Here are the steps you should take:
- Keep calm - wait 1-2 weeks, as the effect often stabilizes.
- Analysis of your visibility via tools such as SISTRIX, Search Console or SEMrush.
- Compare yourself with sites that now rank better: What do they do differently or better?
- Evaluate your content honestly:
- Are they up to date?
- Do they offer real added value?
- Are they comprehensive and well structured?
- Check technology & UX: Loading times, mobile optimization, clear navigation.
- Develop a long-term content strategy instead of just acting reactively.
Key points summarized
- Core updates are algorithmic changes - not manual penalties.
- Losses do not automatically mean bad content.
- Analyze data and competition carefully.
- Revise content with a view to relevance, trust and structure.
- Sustainable SEO is the key - not a "quick fix".
