Diagnosing a sudden drop in organic traffic: a checklist

A sudden fall in search traffic is stressful, and the temptation is to start changing things straight away. Working through the possible causes in order is faster, and stops you fixing the wrong thing.

1. Is the drop real?

• Check the tracking. Compare analytics with Google Search Console. If Search Console clicks are steady and analytics fell, the problem is measurement: a broken tag, a consent banner change, a new site template without the tracking code.
• Compare like with like. Compare with the same period last year as well as last month. Many businesses are seasonal.
• Check the scale. A drop of a few per cent within normal weekly variation is not an emergency.

2. Where exactly did it fall?

In Search Console's Performance report, compare the period before and after the drop and look at:

• Pages: one section, one template or the whole site?
• Queries: brand searches, or non-brand topics?
• Countries and devices: mobile only? One market?
• Search type and appearance: did a rich result or image traffic disappear?

A drop limited to one template points to a technical change; a site-wide drop across many topics points to something broader.

3. Did something change on the site?

Most sudden drops have a cause on the site itself. Check what was released around the date:

• noindex or robots.txt rules added by mistake. See robots.txt vs noindex.
• Redirects, URLs or canonicals changed in a migration or redesign.
• Content removed or merged, or internal links lost in a new navigation.
• Server errors or slow responses: look at the Crawl Stats report and the Page indexing report in Search Console.

Use the URL Inspection tool on an affected page to see what Google sees now.

4. Manual actions and security issues

Open Security & Manual actions in Search Console. A manual action (for example for unnatural links or spam) or a security problem (such as a hacked page) is listed there with what to fix.

5. Search updates

Check the Google Search Status Dashboard, which lists ranking updates with their dates. If the drop lines up with a core update, Google's advice is that there may be nothing specific to fix: look at which pages lost visibility, and assess them honestly for how helpful and reliable they are compared with what now ranks. Recovery after improvements can take time.

6. Competitors and search results

Search your main queries and look at what changed. A competitor may have published something better, or Google may now show more ads, videos, a map or AI-generated answers above the organic results, so the same position gets fewer clicks.

Write it down

Note the date, what you checked, what you found and what you changed. It makes the next drop faster to diagnose, and it is what clients and managers want to see. For how to present it, see How to report SEO results to clients.
