DIGITAL MARKETING
1. Introduction to Digital Marketing
Digital marketing is the promotion of products, services, or brands through digital channels such as search engines, social media, email, and websites. Unlike traditional marketing, digital marketing enables real-time targeting, measurement, and optimisation — making every rupee of your budget work harder.

2. Search Engine Optimisation (SEO)
SEO is the practice of improving a website's visibility in organic (unpaid) search results. It combines technical configuration, content quality, and authority signals to rank higher on Google, Bing, and other search engines.
The Three Pillars of SEO
On-Page SEO
Keyword research and placement, meta titles & descriptions, header tags (H1-H3), image alt text, internal linking, and content depth.
Off-Page SEO
Backlink acquisition, brand mentions, social signals, guest posting, and digital PR campaigns that build your domain authority.
Technical SEO
Site speed, mobile-friendliness, Core Web Vitals, XML sitemaps, structured data (schema markup), and crawlability / indexation.
3. Content Marketing
Content marketing attracts, engages, and converts audiences by providing genuinely useful information rather than direct sales pitches. Great content builds trust, drives SEO, and nurtures prospects across every stage of the buyer journey.
Content Types & Their Goals
• Blog Posts & Articles — Drive organic search traffic and establish expertise.

4. Social Media Marketing
Social media platforms are where your audience spends hours each day. A focused social strategy builds brand awareness, drives website traffic, fosters community, and can generate direct sales through shoppable posts and ads. Platform

Pro Tip: The 80/20 Rule
Post 80% educational, entertaining, or inspiring content and only 20% promotional content. Audiences disengage when every post feels like an advertisement.
5. Email Marketing
Email marketing delivers an average ROI of $36 for every $1 spent — making it one of the highest-return channels available. Success depends on list quality, personalisation, and consistent value delivery.
Key Email Campaign Types
• Welcome Series — Onboard new subscribers and set expectations.
• Newsletters — Share updates, blog posts, and curated industry news.
• Promotional Emails — Announce offers, launches, and limited-time deals.
• Abandoned Cart — Recover lost e-commerce sales automatically.
• Re-engagement — Win back inactive subscribers before you lose them.
6. Analytics & Performance Measurement
Data-driven marketing separates great campaigns from guesswork. Tracking the right KPIs enables continuous improvement, smarter budget allocation, and clear ROI reporting to stakeholders.

Define Goals — Set SMART goals — Specific, Measurable, Achievable, Relevant, Time-bound.
