Social media tools that marketers can use include blogs, microblogs, social networks, media sharing sites, social news sites, location-based social networking sites, and virtual worlds. These tools allow marketers to create and share content, build relationships with customers, promote products and campaigns, and generate traffic to their websites. Mobile technology has also impacted social media marketing. Standardized mobile platforms, fewer privacy concerns, real-time advertising, measurability, and higher response rates have all contributed to the popularity of mobile marketing. Branded mobile apps and widgets allow companies to create buzz, engage customers, and broaden their exposure at lower costs.
