ents, such as PayPerClick (PPC) campaigns via platforms like Google Ads. This method allows businesses to/bid on specific keywords, placing their ads at the top or bottom of SERPs for immediate visibility. While SEM can yield instant results, it is also contingent on budget and competition within specific keyword niches.Both SEM and SEO can strategically complement each other.
