What Are Keywords? – A Basic But Essential Concept
Keywords are the words or phrases that users enter into search engines (Google, Bing...) when they are looking for information.

For example: “SEO services”, “how to write SEO-standard articles”, “how to optimize a website”.

• Keywords help Google understand what your content is about.
• Therefore, it is a bridge between searchers and your content.

Why Are Keywords Important in Web Content Development?

Helps Define the Topic of the Article

• Before writing an article, you need to know what the goal is, what the reader is looking for.
• Keywords are an important suggestion to help you build appropriate article topics and content.

Guides Google to Understand Content

• Google reads website content through metrics (meta title, heading, URL, paragraphs...).
• When keywords are placed appropriately, Google will understand what topic you are talking about, thereby ranking more accurately.

Increase the Chance of Appearing in Search Results

• When your content contains the correct & relevant keywords, Google will prioritize displaying it when users search.
• This helps increase traffic, attracting more potential customers.

Stimulates Users to Click on Articles

• If the title & description contain the exact keywords they are looking for → increases the CTR (click-through-rate).

In short: Keywords are the foundation – the roadmap for Google & users to access your content.

Important Keyword Types in Web Content Development

To understand the role of keywords, let's go through the basic types of keywords:

Primary Keyword

• Is the central keyword – the main topic of the article.
• Usually has high search volume, directly related to the topic.

For example: “role of keywords”.

Secondary Keywords

• Are keywords that expand or are directly related to the primary keyword.
• Helps expand content, avoiding repeating the main keyword too much.

For example: “how to choose keywords”, “the importance of keywords in SEO”.

Long-Tail Keywords

• Are long keyword phrases (3 words or more), more specific, less competitive.
• Focus on detailed needs, helping to reach users with clear goals.

For example: “how to use long tail keywords in SEO”.

LSI Keywords (Related Context)

• LSI (Latent Semantic Indexing) – semantically related keywords.
• Helps Google understand the context of the content, avoiding keyword stuffing.

For example: “Onpage SEO”, “website traffic”, “web content”.

Specific Roles of Each Keyword Type

Primary Keywords – Define Content “Pillars”

• Is the central topic.
• Helps Google identify the main topic.
• Helps keep content focused, avoiding rambling.

Secondary Keywords – Expand Content, Increase Topic Links

• Helps avoid repeating the main keyword too much.
• Makes content richer and more natural.
• Helps Google “recognize” content more comprehensively.

Long-Tail Keywords – Optimize for Specific Search Intent

• Low competition, easier to get to the top.
• Helps attract higher quality customers (they already have specific needs).

LSI Keywords – Clarify Context, Avoid SEO Errors

• Helps the article be natural, avoiding “keyword spam”.
• Increases the “trust score” of the article.

The Role of Keywords in Onpage SEO Factors

In the Title

• A title containing the main keyword helps Google & users recognize it quickly.

Tip: place the keyword as close to the beginning of the title as possible.

In Meta Description

• A description with keywords helps increase CTR – because users will see content that matches their needs.

In URL

• A concise URL containing the main keyword helps Google prioritize it more.

In Heading (H1, H2, H3)

In Content

In Internal Link & External Link
