Google announced the November 2024 core update on 11th Nov. It marked it complete on the Search Status Dashboard on 5th Dec 2024, after 23 days and 13 hours.
It was the third core update of 2024, following the March and August core updates. Google described it as designed "to continue our work to improve the quality of our search results by showing more content that people find genuinely useful and less content that feels like it was made just to perform well on Search."
The rollout ran straight through the Black Friday and Cyber Monday shopping period. Search Engine Land noted this went against expectations that Google would finish before the holiday rush.
Per that coverage, rank trackers picked up the first movement around 13th to 14th Nov. A broader wave came around 16th to 17th Nov.
A fresh spike in ranking swings came around 25th to 26th Nov. Movement continued into early December.
If your site moved in the 11th Nov to 5th Dec window, Google's standing guidance for core updates applies. Audit the pages that lost visibility against the self-assessment questions in the core updates help pages.
Invest in overall helpfulness. Meaningful recovery typically registers at a future core update.
