Spam is a type of content that is of no use to the user. Although it is often used to refer to spam, websites and blogs can also cause spam. In that case we would talk about it Content of no real value to the users as they were created to artificially position a webpage or to promote a product in the wrong way.

To this end, the Google Search team created its own Artificial Intelligence (AI) that independently fights against spam and is so effective that it does able to spot new trends in spam and block them.

Google will find out more than 40,000 pages every day with content classified as spam. To do this, they first use Google Spider, automatic bots that automatically crawl the websites and their content. The information from the XML sitemaps is then used in the search console.

The next filter is the systems that analyze the content that is displayed in the SERPs. When searching, Google analyzes the entire content of the web pages displayed. If any of them contain spam indicators, it will be blocked. This is how the information is Update with every search and Google leaves spam pages out of its results.
The result is that very few spam pages “slide” into the final content that the user has access to. With this in mind, Google ensures that 99% of searches are completely spam free. For the remaining 1%, Google’s own team is taking manual action to fix an issue with these characteristics. The graphic below shows how Google is filtering all of these pages with spam.
