Earlier this week, Google SearchLiaison announced that the second phase of its anti-spam update had begun.
According to Danny Sullivan on Twitter, the update has a direct relation to the previous one. In that announcement, hacked websites were mentioned as an example of spam types.
In response, Google said that they aren’t able to tackle the issue alone and suggested that publishers do their part by keeping their site software up to date.
The second part of our spam update has has begun today, and it will also conclude later today, unless we share otherwise.— Google SearchLiaison (@searchliaison) June 28, 2021
No reason has yet been given for the occurrence of two spam updates and Google has provided no more information than to say the two updates, released one week apart on the same day, were related.
Google is concerned about the following types of spam:
- Automated content
- linking tactics
- Plagiarized content
- Hidden content
- Unstructured data
Yes. It's all part of the same thing, just a second part.— Danny Sullivan (@dannysullivan) June 28, 2021
