Today, Google has announced the March 2024 Core Update. This update identifies the helpfulness of the content. There's nothing new or special that creators need to do for this update as long as they've been making satisfying content for people.
As per Google, the March Core Update is more complex than the usual core updates involving changes to multiple core systems. Google has also launched a new spam policy called the March 2024 spam update.
Expired Domain
Expired domain abuse is where an expired domain name is purchased primarily to manipulate Search rankings by hosting content that provides users little or less value. For example, if someone purchases a domain previously used by a medical site and repurposes that to host low-quality casino-related content, aiming to be successful in SERP on the domain's reputation from a previous ownership
Scaled Content Abuse
Scaled content abuse is when many pages are generated primarily to manipulate Search rankings and not help users. This practice is typically focused on creating large amounts of unoriginal content that provides no value to users,
This new policy is built on the previous spam policy about automatically-generated content which ensures that Google can take action on scaled content abuse as needed, no matter whether the content is produced through automation, human efforts, or some combination of human and automated processes.
Site Reputation Abuse
Site reputation abuse is when third-party pages are published with no first-party involvement, where the purpose is to manipulate search rankings by taking advantage of the first-party site's ranking signals. For example, an educational site hosting a page about reviews of payday loans written by a third party that distributes the same page to other sites across the web.
Google's primary goal with the new policies is to improve spam-fighting systems to ensure that users get great, helpful content.
