December 2024 Spam Update

Prolonged Google SERP Volatility (September – October 2024)

Google search results pages have been experiencing unusually prolonged volatility since the completion of the August 2024 Core Update on September 3, 2024. This volatility, possibly due to an unconfirmed Google search ranking algorithm update, has persisted for a month, continuing into October 3, 2024.

Unconfirmed Search Ranking Algorithm Update (July 2024)

Google may have released an update to its search ranking algorithm between July 18 and August 1, 2024. Several search tracking tools detected volatility similar to that of an algorithm update, and SEOs reported fluctuations in their traffic.

There are considerations that this unconfirmed update may actually be two unconfirmed updates, with one starting on July 18, 2024, and the other one starting on July 22, 2024.

June 2024 Spam Update

Google may have released an update to its search ranking algorithm on February 7 and 8, 2024. Several search ranking tracking tools recorded volatilities on both days, and SEOs observed movements in their search traffic. However, the increased traffic is mostly spam and from outside the US.

Unconfirmed Local Ranking Algorithm Update (Jan 2024)

Google may have released an update to its local ranking algorithm on January 4 and 9, 2024. BrightLocal’s Local RankFlux tool shows the volatility in local search traffic on both days. Local SEOs also reported massive changes in their client’s rankings on January 4, 2024.

That said, it is unclear whether these updates are linked to Google’s openness update. On December 15, 2023, Google confirmed it now considers a store’s opening hours a strong signal for non-navigational search queries. This confirmation came after SEOs noticed businesses vanished from local search results when they were not open.

Unconfirmed Search Ranking Algorithm Update (Dec 2023)

Google may have released an update to its search ranking algorithm, and multiple SERP tracking tools have recorded volatilities on search results pages between December 22 and 24, 2023. Many site owners complained of massive drops in traffic, while others reported a slight increase in traffic. 

However, it remains unclear whether this volatility resulted from an unconfirmed algorithm update or a combination of the usual traffic drop experienced around Christmas and the Google indexing issue of December 21, 2023.
