Asking exactly how many keywords should I use for SEO per page is the first step to ranking higher in 2026. Years ago, we stuffed pages with the same terms to trick search engines. That method does not work anymore. Today, Google and AI tools want topical authority, not just a list of repeated words.
Focusing on a single number for your keyword count is risky. You need a better plan. A strict density limit often hurts your search visibility. Instead, we must look at the “Golden Ratio.” This mix helps you rank on traditional search results and new AI platforms.
Let’s explore the strategy that actually drives traffic.

The Short Answer: The “1-3-5” Rule for 2026
For 2026, the answer to how many keywords you need is simple. Use the 1-3-5 rule. This method stops you from guessing and provides a clear structure for your content.
One Primary Keyword (The Core Topic)
Every great page needs just one primary keyword. This is your main focus. It tells search engines exactly what your content covers. If you target two or three main terms, you confuse the bots. They won’t know which topic matters most. Your core topic must be clear from the start.
Often, this term should be a specific keyword phrase. We call these long tail keywords. They are less competitive and match specific search queries better. This specific focus helps you rank faster. It matches the user intent perfectly. Stick to one strong theme per URL for the best results.
Three Secondary Keywords (The Context)
You need about three secondary keywords to support your main idea. These terms are variations of your primary keyword but offer slightly different angles. They target people who use different words to search for the same problem. Doing proper keyword research helps you find these valuable terms easily. They prove to Google that your content is complete.
Think of these as supporting keywords. They build context around your topic. If your main term is “running shoes,” a secondary one might be “best sneakers for jogging.” Using them helps you capture more search volume. This method ensures your blog post reaches a wider audience. It keeps your text fresh and avoids repetitive language that bores readers.
Five Semantic Entities (The AI Signal)
Finally, include five semantic entities in your content. These are concepts that search engines understand deeply, not just simple text matches. They help semantic search algorithms connect your page to the real world. For example, if you write about “Tesla,” entities could be “Elon Musk,” “Electric Vehicles,” or “Batteries.” This builds trust with AI bots.
These entities are different from old LSI keywords. They define the relationship between ideas. Using them improves your search visibility significantly. You do not need to force them. Just write naturally about your subject, and they usually appear. This strategy signals to search engines that you are an authority. It helps your page rank better in google search results.

Keyword Count by Page Type: One Size Does Not Fit All
The answer to how many keywords varies by page type. You cannot use the same strategy for a blog and a product page. Each page serves a unique purpose. Search engines analyze the structure to guess the goal.
1. How Many Keywords for Blog Posts?
Blog articles allow for the most flexibility. Since the content length is greater, you can include more terms naturally. You should focus on one main idea but include many related keywords. This helps you capture long tail keywords that users type as questions. A single post can rank for dozens of variations.
The goal here is comprehensive information. Search engines reward depth on these pages. You do not need to limit yourself strictly. As long as the words flow well, you can cover the core topic from every angle. This approach builds authority.
2. How Many Keywords for Product/Service Pages?
Service pages require focus. You should target a specific keyword that signals a desire to buy. Do not distract the user with too many keywords or long stories. The text must remain sharp and persuasive. Users land here to take action, not to read.
Stick to a single primary keyword that describes the offer. You can add one or two supporting keywords for context, but keep it minimal. This clarity helps search engines rank you for high-intent searches. Keyword stuffing here can kill your conversion rate. Keep the message direct.
3. How Many Keywords for Homepages?
Your homepage acts as the main hub. It should target your broadest main keyword. This is usually a category term like “AI Marketing Agency”. You can also mix in relevant keywords that describe your top services. However, do not try to rank for every topic here.
Most people search for your brand name on this page. It serves as a navigational tool. Keep the keywords naturally integrated into your headlines. Let your specific service pages handle the detailed queries. A clean homepage signals trust to both users and bots.

Why “Keyword Density” is Dead (And What Replaced It)?
For years, SEO experts obsessed over a specific math formula known as keyword density. They believed that repeating a phrase exactly 2% to 3% of the time was the secret to ranking. This concept is now completely dead. Today, modern search engines represent a major shift in technology. They do not count how many times you repeat a word; they measure the actual value you provide. Focusing on a strict ratio often leads to keyword stuffing, which makes your text unreadable and hurts your performance.
There is no longer a magic number for ideal keyword density in 2026. Instead, Google looks for “Information Gain”, new and unique details that help the user. You should focus on writing naturally and including relevant keywords only where they fit logically. If your content flows well and answers the question, the math will take care of itself.
How Google’s Semantic Search Reads Your Page Today?
Google has changed how it analyzes your content completely. It no longer just scans for exact text matches on the screen. Instead, it uses advanced semantic search technology to understand the real meaning behind your words. The algorithm acts like a smart human reader. It looks at the context of your entire article to see if you truly know your topic.
Here is how the system analyzes your page now:
- Concept Matching: It links your words to real-world concepts, not just isolated terms.
- Intent Checking: It ensures you satisfy the specific user intent behind the query.
- Contextual Depth: It rewards pages that answer related questions fully.
Search engines understand these connections instantly. If you provide the best answer, you will rise in the google search results. You cannot trick the system with repetition anymore; you must write with genuine expertise to win.

Primary vs. Secondary Keywords: How to Split Your Focus?
You need a clear plan for your terms. A successful page balances primary and secondary keywords logically. The primary term acts as your main topic. The secondary ones add necessary detail and context. This division keeps your content focused and organized. It prevents you from targeting multiple keywords that do not fit together.
1. Identifying Your Primary Keyword (Search Intent Matching)
Finding the right main term is vital for visibility. You must use reliable keyword research tools to see the data. A strong choice meets three specific conditions:
- Volume: It has a healthy high search volume.
- Intent: It matches the specific search intent.
- Focus: It is a single primary keyword, not a broad category.
Avoid extremely competitive keywords if your website is new. You might struggle to rank for them immediately. Targeting keywords that answer a direct question often works best. This step builds the foundation for your entire article.
2. Selecting Secondary Keywords That Don’t Cannibalize
Your secondary terms must support the main idea. Look at the related searches section in Google for ideas. These phrases show what else users want to know. Use these supporting keywords to expand your content’s depth. However, be careful not to pick terms that deserve their own page.
Using the same primary keyword on two different pages causes issues. We call this keyword cannibalization. This confuses Google about which page is more important. Ensure every page has a unique job. Your secondary terms should add context, not compete with other articles. This careful selection protects your rankings.
How to Place Keywords for Google and AI Search Engines (GEO)?
Knowing the right count is not enough. You must master keyword placement to succeed. You cannot just sprinkle terms randomly across a single page. You need a specific map. Search engines weigh specific areas of your layout much heavier than others.
1. The “Hot Zones”: URL, Title, and H1
These are the first places a bot looks. Your page title and URL must contain the main term. This is non-negotiable for seo success. The H1 tag acts as the headline for the user. It should match the title tag closely.
- Keep these areas clean and direct.
- Do not clutter them with unrelated keywords.
- Place your focus term in the first one to four keywords.
If you get this wrong, the rest of the optimization matters less. You must capture attention fast.
2. The “Context Zones”: H2s and First Paragraph
Once the bot enters the page, it scans for context. Your H2 subheadings should guide the reader through the logic. Use your secondary keywords here to show depth. The first paragraph is also vital. You must state your main keyword early in the introduction. This confirms to the user they are in the right place.
However, you must write these keywords naturally. If the text sounds forced, you lose the reader. This flow keeps people engaged and lowers your bounce rate effectively.
3. The “AI Zones”: Structured Data & Direct Answers
AI agents read differently than standard bots. They look for data they can extract easily. Lists, bullet points, and tables are perfect for this. You should format your answers clearly to appear in other search engines like Perplexity and ChatGPT.
Using Schema Markup also helps. It labels your content behind the scenes. In digital marketing, we call this optimization for “answer engines.” It ensures your content survives the shift to AI-driven results and stays relevant. You must build structured data to win this game.

Why “Entity Density” Matters More Than Keyword Count?
In 2026, counting simple words is not enough. You must understand a concept called “Entity Density.” This metric is far more valuable than standard keyword density. It measures the number of distinct, real-world ideas you cover in your text. If you create content about a broad topic like “Coffee,” you must mention specific entities like “Arabica,” “Roasting,” and “Beans.”
AI bots scan for these deep connections immediately. They prove you are an expert on the subject. Focusing on just one keyword often leaves big information gaps. High entity density signals to Google that your page is comprehensive. This approach is the best strategy you can use for seo to dominate rankings today.
Common Mistakes: Are You Over-Optimizing?
1. Believing the “2% Keyword Density” Myth
Many writers still cling to the old 2% rule. They count every word to hit a precise math target. This is a waste of your time. Google does not rank pages based on a calculator. It ranks based on value.
If you repeat a phrase just to hit a number, you hurt the reading experience.
- Stop counting: Focus on the flow of ideas.
- Start reading: Read your text aloud to hear repetition.
If you obsess over one keyword, you miss the bigger picture. Trust your gut over the percentage.
2. The Danger of Keyword Stuffing in the AI Era
Keyword stuffing is the fastest way to lose your ranking. In the past, you could hide text or repeat words endlessly. Today, AI models detect this instantly. They see it as low-quality spam.
When you stuff terms, you break the logical structure of your page. Search engines will ignore your content completely. You must use terms only when they add real meaning. If a sentence looks packed with synonyms, delete them. You are writing for a smart algorithm, not a dumb robot. Keep your language clean to stay safe.
3. Targeting Too Many Keywords Per Page
Trying to rank for everything usually means you rank for nothing. A common error is targeting too many keywords on a single URL. This dilutes your page’s authority. You confuse the bot about your main topic.
- The Limit: Stick to the 1-3-5 rule we discussed.
- The Risk: You create a messy, unfocused article.
If you have many keywords you want to use, create multiple pages instead. This keeps your topical relevance strong. Focus allows you to win specific battles rather than losing the whole war.
4. Forcing Keywords Where They Don’t Make Sense
You should never force a term into a sentence if it breaks the grammar. Writers often jam specific phrases into spots where they do not fit. For example, writing “best pizza Chicago” instead of “best pizza in Chicago” looks terrible.
This mistake also happens in hidden areas like alt text for images. Do not describe a photo with a keyword list. Describe the image actually. Google knows when you are lying. Poor grammar signals low quality to users and bots alike. Always prioritize correct, natural English over exact matches.
5. Writing for Bots Instead of Humans
The biggest mistake is forgetting your audience. If you write only to please an algorithm, real people will bounce. High bounce rates tell Google your page is bad. You must prioritize the human reader first.
- Engage: Use stories and clear examples.
- Inform: Answer the questions people search for.
When you satisfy the user, the rankings follow naturally. Do not sacrifice readability for a slightly higher score. Search results favor pages that humans actually love to read. Write with empathy and clarity to win long-term success.

FAQs – How Many Keywords Should I Use Per Page?
Can I Target Two Primary Keywords On One Page?
No. It is best to stick to just one primary keyword per page. If you target two main topics, you risk splitting your relevance. Search engines might get confused about your core focus. It is safer to create separate pages for each major term to maximize your results.
Does Keyword Density Still Matter In 2026?
No, keyword density does not matter like it used to. You should not aim for a specific percentage. Instead, focus on using terms naturally where they fit. If you provide real value, the density handles itself. Google cares about “Information Gain” and context, not math.
How Do I Find Semantic Keywords For My Niche?
You can find these by looking at the “People Also Ask” section in Google. You should also use best keyword research tools that offer semantic suggestions. Look for concepts that experts in your field always mention. Including these terms helps you build a strong knowledge graph for your content.
Will AI Search Engines Punish Me For Keyword Stuffing?
Yes, absolutely. AI models are very sensitive to spam. If they detect keyword stuffing, they will likely ignore your content for citations. They prefer natural, high-quality language. To rank in ChatGPT, Perplexity, or Google AI Overviews, you must write for humans first. Over-optimization is a fast way to lose visibility.
