A SMM (Social Media Marketing) panel is a web-based platform that provides social media marketing services to individuals and businesses. These panels allow users to buy likes, followers, views, and other engagement metrics for various social media platforms, including Facebook, Instagram, Twitter, YouTube, and more.

SMM panels usually work with resellers who buy these services in bulk and then resell them to their clients at a profit. These panels offer various payment options, including credit cards, PayPal, and cryptocurrencies, and they also provide support to their users through ticketing systems, email, and live chat.

It's important to note that some social media platforms have strict policies against the use of fake engagement metrics, and buying such metrics can result in penalties, including account suspensions or bans. Therefore, it's essential to use SMM panels that provide genuine engagement metrics and comply with the policies of social media platforms.
