How Many SEO Keywords Per Page Should You Use? 2025 Guide

Introduction

If you want your content to rank on search engines, understanding keyword usage is crucial. The right balance ensures visibility while maintaining readability. But how many SEO keywords should you use per page? This guide breaks it down for you.

What Are SEO Keywords?

SEO keywords are terms and phrases people enter into search engines to find relevant information. These words bridge the gap between search intent and content visibility, helping websites attract organic traffic.

For example, if someone searches for “best guitar lessons,” that phrase is an SEO keyword. If your content is optimized with this keyword, your page is more likely to appear in search results.

Understanding Primary, Secondary, and Tertiary Keywords

Primary Keywords

Primary keywords are the main focus of your content. They define the article's subject and are used multiple times to reinforce the central idea.

Examples:

• "Marketing"
• "Workout routines"
• "Camping gear"

Secondary Keywords

These are closely related to the primary keyword and support the main topic by providing additional context. They help search engines understand your content better and improve rankings.

Examples:

• "Digital marketing strategies"
• "Home workout plans"
• "Best camping tents"

Tertiary (LSI) Keywords

Latent Semantic Indexing (LSI) keywords are variations, synonyms, or conceptually related terms. They improve content relevance without excessive repetition.

Examples:

• "Online marketing trends"
• "Strength training at home"
• "Camping essentials for beginners"

How Many SEO Keywords Per Page Should You Use?

For effective optimization, use 1 to 4 SEO keywords per page. The keyword density should be between 0.5% and 2%, ensuring a natural flow of content.

Why Use Only One Primary Keyword?

Using multiple primary keywords confuses both readers and search engines. Each piece of content should focus on a single primary keyword to maintain clarity and relevance.

Additionally, when a page is well-optimized for one keyword, it often ranks for multiple related search terms organically.

How to Find Primary and Secondary Keywords

Use Keyword Research Tools

A keyword research tool, like Google Keyword Planner or Ahrefs, helps identify high-impact keywords. Look for:

• High search volume
• Low competition
• Strong relevance to your topic

For example, if “winter fashion” is your seed keyword, tools will suggest related terms like:

• "Best winter outfits"
• "Cold-weather clothing trends"
• "Winter wardrobe must-haves"

Where to Place Keywords for Maximum SEO Impact

Primary Keywords Placement:

• Page Title: Ensures search engines and users understand the topic.
• Meta Description: Improves click-through rate.
• Headings (H1, H2, H3): Reinforces content structure.
• Content Body: Naturally integrate 2-3 times per 500 words.
• Image Alt Texts: Helps with image search rankings.
• FAQs: Strengthens topical authority.

Secondary Keywords Placement:

• Subheadings (H2-H6): Enhances readability and SEO.
• Body Content: Use at least once.
• Anchor Text for Internal Links: Improves navigation and keyword relevance.
• FAQ Sections: Addresses search intent variations.

Final Thoughts

To optimize your content effectively, focus on 1 primary keyword and 2-4 secondary keywords per page. Avoid keyword stuffing and prioritize natural placement.
