Google announced the launch of the spam update “a normal spam update” on September 24 and said that it might take almost 2 weeks to be completely rolled out. It finally announced the completion of the rollout on October 8.

It was said to affect the entire globe, all languages. Google confirmed on its Search Status Dashboard the completion of the update.

Google’s September Spam Update: Key Details

Google’s September spam update targets websites that use practices against its spam policies. The update applies globally across all languages and is designed to improve the quality of Google Search results. Google has not disclosed the specific spam techniques targeted by this release.

Google’s spam update documentation explains how its automated systems help identify search spam. These updates aim to improve the quality of results by addressing websites that violate Google’s spam policies.

Initial Data Shows Website Traffic Changes During the Rollout

On September 29, Diib shared an early study of 32,569 websites linked to Google Analytics. The data showed that the typical share of visits from unpaid Google Search fell from 34% to 31%.

The data has limits:
• It covers only September 24-26, the first three days of the rollout, compared with the same days a week earlier.
• Diib used a share metric because overall traffic fell that week.
• Diib called the findings “an early read, not a verdict” and said they cannot show which sites Google treated as spam.
• Google has not confirmed any impact data.

Search Ranking Changes After the Update

Google’s September spam update may affect how some websites appear in search results. However, a drop in rankings does not always mean a site has broken Google’s spam rules. The company has not identified the websites affected by this update or explained which specific spam practices it targeted.

This leaves the exact impact of the rollout unclear, as Google has shared only limited details about the changes made to its spam detection systems.
