What is Marketing Funnel (Awareness → Conversion)
The marketing funnel illustrates the customer journey:
- Awareness: Attract attention (blog posts, social ads).
- Interest: Engage and educate (lead magnets, newsletters).
- Desire: Build preference (case studies, demos).
- Action: Convert (purchase, sign‑up).
Target Audience & Buyer Persona
A buyer persona is a semi‑fictional representation of your ideal customer based on market research and real data. Include demographics, pain points, goals, and behavior patterns.
Competitor Analysis
Identify your top competitors and analyze their digital presence: website, SEO, social media, content, and ad strategies. Tools: SEMrush, Ahrefs, SimilarWeb.
SWOT Analysis
Evaluate your own business: Strengths, Weaknesses, Opportunities, Threats. Use this to inform your strategy.
Creating Marketing Strategy Plan
Define objectives (SMART goals), choose channels, allocate resources, and set a timeline. Include content pillars, key performance indicators (KPIs), and a budget.
Budget Planning
Decide how much to spend on each channel based on expected ROI. Start small, test, and scale winning campaigns. Include tools, ad spend, and personnel costs.
What is a Website?
A website is a collection of web pages under a single domain. It serves as your digital storefront and the hub of your digital marketing efforts.

A domain is your website’s address (e.g., example.com). Hosting is the server space where your files reside. For most marketing sites, shared hosting works initially; scale to VPS/cloud as traffic grows.
Landing Page vs Website
A landing page is a standalone page designed for a single conversion goal (e.g., sign‑up, purchase). A website contains multiple pages and serves multiple purposes. Landing pages often have no navigation to keep focus.
Conversion‑Focused Design
Use clear CTAs, minimal distractions, trust signals (testimonials, security badges), and persuasive copy. Place key elements above the fold.
UX/UI Basics
UX (User Experience): How a user feels navigating your site. Focus on ease, speed, and intuitive flow. UI (User Interface): Visual elements – layout, colors, fonts, buttons. Good UI supports good UX.
What is SEO?
SEO is the practice of improving your website to increase organic visibility in search engines like Google. It involves optimizing content, technical setup, and building authority.
How Search Engines Work
Search engines use crawlers (bots) to discover pages, index them, and then rank them based on relevance and authority. Factors include keywords, backlinks, site structure, and user engagement.
Types: On‑page, Off‑page, Technical SEO

- Long‑tail: 3+ words, lower volume, higher intent, easier to rank (e.g., “how to create a digital marketing strategy”).
Search Intent
Understand why a user searches: informational (learn), navigational (find a site), transactional (buy), commercial (research before buying). Match content to intent.
Competitor Keyword Analysis
