Black Hat SEO is the use of manipulative or deceptive practices to achieve a higher rank in search engines. Participating in link schemes, generating automatic content (or auto-generated content), and placing hidden text or links on web pages are a few examples of disapproved practices by Google.
As a result, it’s important to avoid using any techniques that could be considered blackhat if you want your website to maintain a good ranking.
Black hat seo may get you quick results, but it’s not worth the risk. Google will eventually figure out what you’re doing and penalize your site. Play it safe and stick to white hat SEO practices.
