✅ What is SEO Spam?

SEO spam, also known as Spamdexing or search engine spam, is a black-hat SEO tactic where hackers or malicious actors inject malicious content into a website to manipulate search engine rankings. This is often done without the site owner’s knowledge and can harm your website’s reputation, rankings, and even get you blacklisted by search engines like Google.
