Mastering SEO: Keywords Per Page

Summary: Stop obsessing over keyword counts. Learn how to build topic-focused pages that use one primary keyword plus related terms to rank for many searches.

Introduction

Forget the old keyword-density rules. Modern SEO rewards pages that fully answer user intent by covering a topic in depth with one clear primary keyword supported by related terms and questions. This approach improves relevance, readability, and long-term rankings.

Let’s Cut to the Chase

How many keywords should you target on a single page? Focus on one primary topic and support it with a natural set of related keywords. Trying to force a specific number of keywords is outdated and often produces awkward copy.

Rethinking the Keyword Count

SEO used to be a numbers game focused on keyword density. Today’s search engines understand context, synonyms, and searcher intent, thanks to advances in language understanding¹. That means a single page should act like a chapter in a book: centered on one core idea and expanded with related subtopics and questions.

The Shift From Quantity to Quality

Instead of asking “how many keywords can I fit in?”, ask “how well does this page satisfy the user’s search intent?” Your goal is to answer visitors’ questions fully so they don’t need to click back to search for more information. Search engines reward that user-first focus.

Old vs Modern Keyword Strategy

A single, well-written page can rank for hundreds of related queries. That’s far better than producing many thin pages each targeting minor keyword variants.

Why This Approach Is Better for Business

Topical authority connects SEO to real business outcomes. Before you build, estimate the potential return using calculators that model value and profit. For example, use the Business Valuation Estimator to frame expected long-term value, or the Email List Value Estimator to understand the value of incremental leads.

Why Keyword Density Is an Outdated Metric

The old “2% keyword density” rule led to unnatural, unreadable text. Modern algorithms evaluate language and context, so repeating a keyword for its own sake rarely helps. In fact, research shows top-ranking pages don’t rely on high keyword density—trying too hard to repeat a term can backfire².

Write for people first. High-quality content naturally includes related words and phrases that signal topical relevance to search engines. Worrying about a specific density distracts from creating the best possible resource.

Focusing on Primary and Secondary Keywords

Think of your page as a stage show. The primary keyword is the headliner; secondary keywords are the supporting cast. The primary term defines the page’s purpose, while secondary terms add depth and answer related questions.

Assigning Your Keyword Roles

Start with thorough keyword research to see what users actually search for. Pick one primary keyword that best matches the page’s intent and several secondary terms that naturally flow into the content.

Example for a small business finance site:

• Primary Keyword: “small business financing”
• Secondary Keywords: “how to get a business loan,” “SBA loan requirements,” “best business loan rates,” “equipment financing options”

By building a page around one primary topic and a rich set of related terms, you increase your chances of ranking for many related queries.

Tying Keywords to Business Goals

Keyword selection should be a business decision. Use estimators to check that the traffic and conversions you expect justify the content investment. Tools such as the Business Valuation Estimator help translate content work into projected financial outcomes.

Building Authority with Topic Clusters

A single page is powerful, but a cluster of pages around a pillar topic is stronger. Create a high-level pillar page for a broad topic and link out to in-depth cluster pages that each cover subtopics. Smart internal linking signals authority and helps search engines understand your site’s structure.

Shifting Focus From Keywords to Topics

When you build topic clusters, the question of “how many keywords per page” becomes less relevant. The focus shifts to providing comprehensive coverage across a group of connected pages. Studies that analyze large sets of search results show pages covering many related subtopics tend to outrank narrowly focused competitors³.

Justifying the Investment in Topic Clusters

Creating a topic cluster requires planning and content resources. Treat it as a strategic investment. Use tools like the Business Valuation Estimator to build a financial case for the effort, showing stakeholders the potential return.

How to Place Keywords on Your Page

Strategic placement beats repetition. Put your primary keyword where it matters most, and weave secondary terms into the content naturally.

Prime Real Estate for Your Primary Keyword

Place the primary keyword in these high-impact locations:

• Title tag (search results headline)
• H1 heading (page’s main visible title)
• URL (clean, readable slug)
• First 100 words (establish topic immediately)

These placements send the strongest signals about your page’s focus.

Weaving in Secondary Keywords Naturally

Use secondary keywords where they improve clarity and flow:

• Subheadings (H2, H3) to organize topics
• Body content, where terms fit naturally
• Image alt text for accessibility and image search
• Internal link anchor text to related pages

As a guideline, many SEOs find natural usage falls between 0.5% and 2% density, but placement and user value matter far more than a specific percentage.

Measuring Your Keyword Performance

Track the metrics that tie directly to business impact: organic traffic, keyword rankings, click-through rate (CTR), and conversions. Free tools like Google Search Console provide actionable data to diagnose issues and refine content.

If a page ranks well but has low CTR, improve the title tag and meta description. If it has traffic but few conversions, check for an intent mismatch and adjust the content or calls to action.

Tying SEO Metrics to Your Bottom Line

Connect SEO improvements to revenue to show tangible impact. Small improvements in conversion rate can produce outsized gains in revenue. Use tools such as the Email List Value Estimator or the YouTube Channel Value Estimator to model how traffic and conversion changes translate into monetary value.

Common Questions Answered

Is It Okay to Target More Than One Primary Keyword?

Generally, no. Trying to rank one page for multiple distinct primary keywords can cause keyword cannibalization, where your own pages compete against each other. Give each page one clear primary topic, supported by related secondary keywords.

How Do I Find Good Secondary Keywords?

Look at Google’s “People Also Ask” and “Related Searches” for quick ideas. For deeper research, competitive tools such as Ahrefs or Semrush reveal which terms your competitors rank for and uncover opportunities.

Does Putting the Keyword in the URL Still Matter?

Yes. A clean URL with the primary keyword is still a helpful signal and improves user trust compared with opaque query strings.
