SEO is the process of optimizing websites for search engines to obtain organic traffic, high-quality leads, and elevate the revenue generation rate. It is considered one of the significant parts of digital marketing. Besides this, other aspects of digital marketing, such as PPC (Pay Per Click), SMM (Social Media Marketing), Content Marketing, Email Marketing, Influencer Marketing, Affiliate Marketing, and Display Advertising, are also effective. But they can’t match the long-term success of SEO.
