SEO spam, also known as search engine spam, refers to tactics that aim to manipulate search engine rankings through practices deemed unethical or against search engine guidelines.

Common methods include the excessive use of keywords in content or meta tags, which are intended to trick search engines into ranking a site higher than it deserves.

However, search engines like Google employ sophisticated algorithms designed to detect such spammy behaviors. Once identified, these practices can lead to penalties for the offending website, including lowered rankings or complete removal from search results.

This not only ensures compliance with search engine guidelines but also promotes a better, more sustainable relationship with users.
