Search Engine Optimization (SEO) is a digital marketing strategy that uses specific keywords to make websites more appealing to search engines and boosts online visibility. Benefits include increased credibility through Google reviews and organic search results, and enhanced online presence via social media. Implementing SEO varies across e-commerce, brick-and-mortar retail, and service-based businesses. While it works effectively with paid advertising, SEO is a long-term strategy that aids in attracting genuine visitors interested in a business’ offerings.
