Major Components of Digital Marketing
Digital marketing is made up of multiple strategies. Let’s explore them in detail.
1. Search Engine Optimization (SEO)
SEO helps your website rank higher on Google. When people search for something related to your business, your website should appear at the top. SEO has three major parts:
- On-Page SEO: Content optimization, keywords, headings, internal links.
- Off-Page SEO: Backlinks, guest posting, brand signals.
- Technical SEO: Website speed, indexing, schema, sitemaps.

Social media platforms like Facebook, Instagram, YouTube, TikTok, LinkedIn, and Twitter help grow audience engagement. Brands use them to promote products, run campaigns, and build trust.
