With the Helpful Content Update, Google is aiming to ensure that content is created for people and adds value. Content that is created just for visibility will be detected by Google and can negatively impact rankings. If you’ve been following best practices and creating valuable content for users, the Helpful Content Update shouldn’t have a negative impact and could even improve your rankings. However, a new perspective is that Google will likely evaluate quality at the domain level, not on an individual page. This means that „bad“ content on a site can also hurt the „good“ content.
If you have content that doesn’t add value to your readers, was created just for search engines, or merely summarizes content from others, you should consider removing it.
