How Many SEO Keywords Should You Use Per Page?
The best number of keywords for SEO isn't a fixed count. It's about choosing one primary keyword and the right secondary keywords so your page covers its topic well enough to be genuinely useful.
The shift in thinking
“Use your primary keyword 5 times and keep density at 2%”
“Pick one primary keyword plus a few secondary keywords that share the same intent”
“Does this page thoroughly cover the topic a shopper cares about?”

Target one primary keyword and two to five secondary keywords per page. But understanding why matters more than memorizing numbers.
Search Engines Understand Topics
Google and other search engines use language models to understand what a page is about. They don't count how many times you say “running shoes.” They understand that cushioning, pronation, and trail vs road are all part of the running shoe topic. A page that covers the topic well will outrank one that repeats the same phrase.
Secondary Keywords Add Depth
Secondary keywords are closely related terms that support your primary keyword. They help search engines understand the full scope of your content. For example, if your primary keyword is “women's running shoes,” secondary keywords like “trail running shoes,” “lightweight running shoes,” and “running shoe sizing guide” naturally broaden your page's relevance.
Write for the Person Reading
The best approach has always been the simplest: write content that's genuinely helpful. If someone lands on your category page for women's running shoes, what would actually help them? Size guides, materials, use cases, price ranges. Those are naturally the words search engines want to see too.
Primary Keywords vs Secondary Keywords
Every page needs one clear primary keyword that defines its core topic. Secondary keywords expand that topic naturally and help you capture more search queries.
What Is a Primary Keyword?
Your primary keyword is the single term that best represents the search intent of your page. It belongs in the title tag, H1, URL, and the first paragraph. If a page tries to rank for two unrelated primary keywords, it often ends up ranking for neither.
What Are Secondary Keywords?
Secondary keywords are variations, long-tail phrases, and related subtopics that support the primary keyword. They appear naturally in subheadings, body paragraphs, image alt text, and lists. Good secondary keywords share the same user intent as the primary keyword but capture different phrasings.
Example for a “women's running shoes” page:
- • Primary: women's running shoes
- • Secondary: best running shoes for women
- • Secondary: women's trail running shoes
- • Secondary: lightweight running shoes women
- • Secondary: running shoe size guide
How Many Keywords Should a Website Have?
A website should have as many keyword-focused pages as there are distinct topics your audience searches for. Each page targets its own primary keyword, so the total depends on the breadth of your catalog or content.
Best Number of Keywords for SEO by Page Type
How many keywords you should use depends on the type of page. Here are practical guidelines for the most common page types.
Category Pages
Category pages should target one primary keyword (the category name) plus several secondary keywords covering product types, attributes, and shopper questions.
- • 1 primary keyword (category name)
- • 3-5 secondary keywords (subtypes, features)
- • Cover product attributes and use cases
- • Include practical details like sizing and price ranges
Product Pages
Product pages naturally target the product name as the primary keyword. Secondary keywords include materials, use cases, and buyer-intent terms.
- • 1 primary keyword (product name + type)
- • 2-4 secondary keywords (features, materials)
- • Describe what it is and who it's for
- • Include specs, compatibility, and care details
Blog Posts
How many keywords per blog post? Focus on one primary keyword in the title and H1, then weave in secondary keywords throughout subheadings and body text.
- • 1 primary keyword (main topic)
- • 3-8 secondary keywords (related questions)
- • Use secondary keywords in H2s and H3s
- • Answer related questions naturally

The Content Agent writes and improves page content by understanding what each page's topic is and covering it naturally, incorporating primary and secondary keywords without stuffing.
Topic Understanding, Not Keyword Insertion

- • Understands the full topic, not just the head term
- • Selects appropriate secondary keywords automatically
- • Writes content that helps shoppers make decisions
- • Natural language that reads well to humans
Works Across Your Whole Catalog
When you have thousands of category and product pages, the Content Agent ensures each one targets its own specific keywords and covers its topic well, without repeating the same generic copy everywhere.

- • Useful, specific information on every page
- • Consistent quality across your entire catalog
What the Content Agent Does
How Many Keywords Should You Optimize For?
The answer depends on your site's size, your content strategy, and how competitive your niche is. Here's a practical framework.
Per-Page Strategy
Each page should focus on one search intent. If two keywords represent different intents (e.g., “buy running shoes” vs “how to clean running shoes”), they need separate pages.
When keywords share the same intent (e.g., “best running shoes” and “top running shoes”), they belong on the same page as primary and secondary keywords.
The Topic Sieve helps identify which topics and secondary keywords genuinely belong together on each page, so you don't accidentally split a single intent across multiple pages or combine conflicting intents on one page.
Site-Wide Strategy
The New Pages Agent evaluates gaps in your catalog where shopper demand exists but no page currently targets it. The Content Agent identifies existing pages that need deeper topical coverage or better secondary keyword integration.
Together they ensure your site addresses the full range of relevant topics. The Linking Agent connects related pages with strong internal links, reinforcing topical authority across your catalog.
The Cleanup Agents identify pages that compete with each other for the same keywords and recommend consolidation, so your SEO efforts aren't diluted by keyword cannibalization.
Frequently Asked Questions
How many keywords per page for SEO?
Most SEO experts recommend targeting one primary keyword and two to five secondary keywords per page. The exact number matters less than ensuring every keyword aligns with a single, coherent search intent so the page stays focused and useful to readers.
How many keywords should I use for SEO?
There is no single magic number, but a practical guideline is one primary keyword plus a handful of closely related secondary keywords per page. The best number of keywords for SEO depends on the depth of your topic and how naturally you can weave them into headings, body text, and metadata.
How many keywords should a website have?
A website should have as many keyword-focused pages as there are distinct topics worth covering for your audience. Each page targets its own primary keyword and related terms, so a large e-commerce site might cover hundreds or thousands of keyword themes across category and product pages.
How many keywords per blog post?
A blog post typically performs best when it focuses on one primary keyword supported by three to eight secondary keywords that are semantically related. Covering the topic thoroughly matters more than hitting an arbitrary count, because search engines reward depth and relevance over repetition.
How many keywords should you optimize for on a single page?
You should optimize a single page for one core keyword and a small cluster of secondary keywords that share the same search intent. Trying to optimize one page for too many unrelated keywords dilutes its focus and often leads to lower rankings for all of them.
Better Keywords, Better Content, Every Page
The Content Agent identifies the right primary and secondary keywords for each page in your catalog, then writes content that covers the topic naturally and thoroughly. No keyword stuffing, no thin pages.
