Digital marketing is the use of online channels – search engines, social media, email, websites, apps, and digital ads – to reach, engage, and convert audiences.
It encompasses everything from SEO and PPC to content, influencer, affiliate, and performance marketing. The goal: drive measurable outcomes across awareness, demand, and revenue funnels.
Digital marketing turns every impression, click, and view into a data point – it’s where creativity meets analytics.
