Pay-Per-Click (PPC) is a digital advertising model where advertisers pay a fee each time their ad is clicked. It is commonly used in search engine advertising (Google Ads) and social media platforms. PPC campaigns involve keyword bidding, audience targeting, and ad optimization to drive traffic and conversions. Key elements include ad copy, landing pages, and budget management. PPC provides immediate results, measurable performance, and high ROI when executed effectively. Strategies like A/B testing, negative keywords, and quality score improvement enhance campaign success. PPC is a powerful tool for businesses looking to increase visibility, leads, and sales quickly.
