Keywords in SEO: Full Beginner-Friendly Guide
Imagine someone sitting at their desk, unsure how to start searching for something they need. They type a phrase like “affordable online marketing course fees” — that phrase becomes a keyword. Every search starts with a word, an idea, or a question. That is why understanding keywords is the foundation of SEO.
If you choose the right keywords, your website gains more traffic, leads, and conversions — naturally and consistently.
1️⃣ What Are Keywords?
Keywords are the words or phrases people type into Google when looking for information, services, or products. In SEO, keywords help you optimize content so your website appears for the right searches.
Example: A student searches → “SEO course fees in India”. That’s a keyword.
2️⃣ What Is Keyword Search Volume?
Search volume tells you how many times a keyword is searched in one month.
Example:
- Keyword: “digital marketing bootcamp”
- Search Volume: 3,200 searches per month
3️⃣ Types of Keywords
Short-Tail Keywords (1–2 words)
Broad, highly competitive, and less specific.
Examples: “Shoes”, “SEO”, “Courses”
Long-Tail Keywords (3+ words)
More specific, lower competition, and usually higher conversion rates.
Example: “best affordable digital marketing bootcamp for beginners”
LSI Keywords (Latent Semantic Indexing)
These are related keywords that help Google understand context and relevancy.
Example: If your keyword is “Digital Marketing Course”:
- Related terms: “content marketing course”, “email marketing classes”, “social media advertising course”
4️⃣ Types of Keyword Competition
Competition shows how hard it is to rank for a keyword.
- Low Competition: Easy to rank
- Medium Competition: Requires some effort and optimization
- High Competition: Hard to rank — usually very popular keywords
Example:
- Low: “Best SEO course online free”
- High: “SEO course”
5️⃣ What Is Keyword Difficulty (KD)?
Keyword Difficulty measures how hard it is to rank on Google’s first page for a keyword. KD is expressed in percentages.
Example:
- Keyword: “digital marketing belhi”
- KD: 65% → moderately difficult
6️⃣ What Are LSI Keywords?
LSI keywords are related phrases that support your main keyword and help Google understand the depth of your content.
Example:
- Main keyword: “PMP certification”
- LSI keywords: “PMP syllabus”, “PMP training fees”, “PMP online coaching”
7️⃣ What Is Google Autocomplete?
When you start typing in Google’s search bar, Google suggests trending and relevant search terms. This feature is called Autocomplete.
Example: Type: “SEO course D…”
- “SEO course Delhi”
- “SEO course online”
- “SEO course fees”
8️⃣ What Is Keyword Stuffing?
Keyword stuffing is when keywords are inserted unnecessarily or excessively to manipulate rankings. This harms SEO and may lead to penalties.
9️⃣ What Is Keyword Density?
Keyword density measures how many times a keyword appears in your content compared to total word count.
Example: 1 keyword in 100 words → density = 1%
🔟 What Is Keyword Intent?
Keyword intent shows the purpose behind a user’s search — what they truly want to achieve.
Informational Intent
The user wants answers or information.
Example: “What is PMP certification??”
Navigational Intent
The user wants to reach a specific website or brand.
Example: “Coursera project management course”
Transactional / Commercial Intent
The user wants to buy, enroll, or take action.
Example: “Sign up for digital marketing bootcamp”
