Social media has become popular for business use because classic advertising methods have lost effectiveness. Consumers are exposed to many ads and don't trust brand messages as much. They now do most purchase research online. Businesses use social media for communication, SEO, and monitoring. It allows them to create engaging content, build relationships, promote events, gain links for SEO, and learn what people say about their brand to improve. Monitoring tools help track key metrics like followers, shares, comments and see analytics by date, website, location and sentiment.
