Sudden ranking drop? Check your SEO data before acting

27 October 2026 · 4 min read · Marketing Scan

This article was translated from Dutch.

Short answer: do not change your website solely because one rank tracker reports a sudden drop. On October 27, 2026, Semrush described automated Google requests that can receive different results from those a typical user would see. Compare the alert with Search Console, the same query and a longer time window.

This does not prove that your own drop is a measurement error. Technical failures, competition and changing demand remain possible. The useful question is which independent signals support the conclusion.

What have data providers actually reported?

In its statement reflecting its understanding on October 27, Semrush describes normal-looking results that do not match the full search query. It says it excludes clearly invalid results and collects potentially inaccurate results again. AccuRanker also describes its own checks and limitations.

These are commercial providers discussing their own data. Semrush says Google has not commented publicly on the suspected cause. Do not present the proposed explanation as Google’s confirmation, or conclude that every ranking report is wrong. The concern is about some automated result collections.

Recognise a suspicious measurement without ignoring a real problem

A sharp drop that disappears the following day, results from the wrong location, or several familiar competitors vanishing together are reasons to investigate. None is conclusive alone. A genuine Google test can also change a results page.

Save the query, date, country, location and device from the alert. A desktop measurement for the Netherlands is not directly comparable to a mobile search in Belgium. Make the comparison consistent before trying to explain the difference.

Compare the same question in Search Console

  1. Open the Performance report for the correct website property.
  2. Filter to the page and query where the query is available.
  3. Use a matching date range, country and device.
  4. Review impressions, clicks and average position together.
  5. Compare a longer period to identify an isolated outlier.

Search Console contains Google’s own search-performance data, but it is not an identical rank-tracker measurement. Average position aggregates real impressions across different circumstances. Small or anonymised queries may be absent, and recent data may be incomplete. A missing row does not prove there were no visits.

When should you still change the website?

Investigate immediately when important pages fail, have an unintended noindex instruction or redirect to the wrong destination. When relevant impressions and clicks also fall over time, look into indexing, content and competition. A possible measurement problem should not become an excuse to ignore a genuine fault.

Avoid rewriting dozens of page titles in response to one alarm. After checking the evidence, make one justified change and keep the baseline. That makes the next comparison more useful without attributing every fluctuation to your latest edit.

Turn a dashboard alert into a verifiable action

Record four things: the original alert, your Search Console check, a technical check of the page and the action you chose. When reporting to a client, explain where the data remain uncertain. A qualified explanation is more useful than a confident diagnosis without evidence.

In Marketing Scan, you can save your website and connect a suitable Search Console property to explore real search queries and growth opportunities. The platform cannot make supplier or Google data infallible and does not prove the causal effect of an edit. It helps you move from a score to a concrete next action. Start with what a free website audit actually measures.

Frequently asked questions.

Has Google confirmed that it is misleading ranking tools?

Semrush says Google has not commented publicly. A provider’s explanation should not be presented as confirmation from Google.

Is my ranking drop definitely a data problem?

No. Check page availability, indexing and your own Google performance data. A genuine decline remains possible.

Should Search Console and my rank tracker show the same position?

No. Search Console aggregates real impressions. A tracker measures a particular search under configured conditions.

Can I follow search queries in Marketing Scan?

Yes, after connecting a suitable Search Console property you can review available query data and follow relevant opportunities. Better rankings are not guaranteed.
