While PPC focuses on paid ads displayed on search engine result pages or other platforms, SEO (Search Engine Optimization) is the process of improving your website's visibility organically in search engine rankings. Social media advertising, on the other hand, involves paid promotion of ads on social media platforms to reach a specific audience. PPC offers immediate visibility and control over ad placement, while SEO and social media advertising provide long-term organic growth and engagement. Each platform has its unique benefits and strategies, and a comprehensive digital marketing campaign may involve a combination of these approaches to achieve optimal results for your business.
