Keyword Placement Guide: Where to Put Your Keywords for On-Page SEO

Effective keyword usage is about placement, not just volume. Learn the optimal locations for your Primary, Secondary, and LSI keywords to maximize search engine visibility and relevance.

Step 1: Understand Your Keyword Hierarchy

Before placing keywords, categorize them based on importance to the page's topic:

  • Primary Keyword (Focus Keyword): The single most important term the page is designed to rank for. (e.g., "Best Electric Scooters")
  • Secondary Keywords: Close variations or high-volume terms related directly to the primary topic. (e.g., "Electric Scooter Reviews," "Top-Rated E-Scooters")
  • LSI & Semantic Keywords: Contextual terms and related concepts that prove topical expertise. (e.g., "Battery life," "Max speed," "Folding mechanism," "Commuting")
Step 2: Optimal Keyword Placement Checklist

Use this table to ensure your keyword types are strategically placed in the most impactful SEO elements:

HTML Element Keyword Priority Notes & Best Practice
**Title Tag** ($\langle\text{title}\rangle$) Primary (MUST HAVE) Must include the Primary Keyword, ideally near the beginning. Keep under 60 characters.
**URL Slug** Primary / Secondary Short, descriptive, and contains the Primary Keyword. Use hyphens to separate words.
**H1 Tag** ($\langle\text{h1}\rangle$) Primary (MUST HAVE) The main headline. Should be a close variant of the Title Tag but often more engaging. Only one per page.
**Meta Description** Secondary / Primary Should include the Primary Keyword but primarily serves as an ad copy to increase **Click-Through Rate (CTR)**. Keep under 155 characters.
**First 100 Words** Primary / Secondary Crucial for establishing relevance immediately for crawlers and users.
**H2/H3 Tags** Secondary / LSI Use $\langle\text{h2}\rangle$ tags for main section headers, including Secondary Keywords. Use $\langle\text{h3}\rangle$ for sub-sections with LSI terms.
**Image Alt Text** LSI / Secondary Use descriptive language containing relevant LSI or Secondary Keywords (e.g., `Red Vespa electric scooter charging`).
**Internal Links** Primary / Secondary Use the Primary Keyword as the **anchor text** when linking to this page from other related pages on your site.
Step 3: How to Arrange Keywords Naturally
Principle of Moderation (Keyword Density)

Do not force keywords. Google values natural language. High keyword density is a relic of old SEO and can lead to a "keyword stuffing" penalty. Your goal is to write for the user first, then optimize for the engine.

Tips for Natural Inclusion:
  • Variations are Key: Instead of repeating the Primary Keyword, use synonyms and long-tail variants. This is where LSI keywords shine, demonstrating comprehensive coverage.
  • Strategic Density: Aim for a higher density of the Primary Keyword in the top third of the page (Title, H1, first paragraph) and a lower, more contextual density throughout the remaining content.
  • Content Siloing: Ensure every paragraph serves a specific sub-topic (H2 or H3), and that the language within that paragraph naturally includes the corresponding Secondary or LSI keyword.
  • Actionable Advice: Always ask: "Does this sentence sound natural to a human?" If the answer is no, rephrase it, even if it means slightly changing the keyword.

**Warning:** Never use keywords in a way that hides them from users (e.g., white text on a white background). This is a severe violation of Google's guidelines.
