However, before I answer the question on how many keywords you should use for content writing, let’s get to know some important things about SEO Keywords.
A Quick Overview on SEO Keywords
SEO keywords are essential terms or phrases used in web content that help search engines connect users to relevant websites.
They play a critical role in search engine optimization (SEO) by enabling search engines to understand the content of a page and rank it accordingly in search results.
The primary goal of using keywords is to ensure that a website appears in search results for the queries potential customers are entering.
By optimizing content around specific keywords, businesses can attract users who are actively searching for their products or services, enhancing the likelihood of conversions.
In the next section, I will talk about the types of keywords available when it comes to content creation or writing.
Types of Keywords
Generally, there are four (4) types of keywords. They include:
1. Seed Keywords
Seed keywords are the foundation of your keyword strategy. They are broad, high-volume terms that represent the core topic of your content.
These keywords serve as starting points for further research and help you identify related keywords and topics to cover.

Seed keywords are useful for understanding the overall landscape of your niche and identifying areas to explore further.
However, they are often highly competitive and difficult to rank for, especially for newer websites.
2. Long-Tail Keywords
Long-tail keywords are more specific, less competitive phrases that typically have lower search volume. They are longer and more detailed than seed keywords, often containing 3-5 words.
Long-tail keywords are valuable because they:
- Reflect more targeted user intent
- Face less competition from other websites
- Can drive qualified traffic to your site

While long-tail keywords have lower search volumes individually, collectively they can drive a significant amount of traffic to your site.
They are especially useful for niche topics and can help you attract visitors who are closer to making a purchase decision.
3. Keywords by Search Intent
Understanding search intent is crucial for aligning your content with what users are looking for.
There are four main types of search intent:

i. Informational:
Informational keyword search intent refers to the motivation behind a user’s search query when they seek knowledge or information about a specific topic.
This intent is foundational in the search process, often occurring at the beginning of the buyer’s journey.
Users typically employ question-based keywords such as “what,” “how,” “who,” and “why” to gather facts, guidance, or background information.
Some key characteristics of informational search intent:
- Users looking for information often prefer content that includes how-to guides, definitions, tutorials, and FAQs.
- Users may not have a specific question in mind but are looking to explore a topic.
- Search engines like Google prioritize providing direct answers to these queries, often showcasing featured snippets, knowledge panels, or direct answers at the top of search results.
For example, “Tallest mountain in the world” or “How to tie a tie.”
ii. Navigational:
Navigational search intent occurs when a user enters a query into a search engine with the goal of reaching a specific website or web page.
Rather than typing the URL directly into the address bar, the user opts to search for the site on Google or another search engine.
Some key characteristics of navigational search intent:
- The user already has a particular website in mind that they want to access
- Queries often include the brand name, product name, or website name
- The user is not looking for information, but rather a specific destination
- Click-through rates on navigational queries are usually high
- Navigational queries are less valuable for SEO purposes since the user is looking for a particular site.
For example, “Facebook login” or “SiteChecker Pro homepage.”
In each of these cases, the user is not looking for information about the brand or website, but rather wants to be taken directly to that specific destination.
iii. Transactional:
Transactional search intent occurs when a user enters a query into a search engine with the goal of making a purchase or completing a specific action.
These users are typically ready to convert and are further down the sales funnel compared to those with informational or commercial intent.
Some key characteristics of transactional search intent:
- The user is ready to take action, such as buying a product, signing up for a service, or downloading software
- Queries often include words like “buy,” “for sale,” “discount,” “coupon,” “price,” or the name of a specific product or brand.
- Click-through rates on transactional queries are usually high, but bounce rates can be high if the landing page doesn’t match the user’s expectations
Transactional queries are extremely valuable for SEO and PPC purposes since they indicate a strong purchase intent.
For example, “Buy iPhone 12” or “Netflix subscription plans.”
In each of these cases, the user is looking to take a specific action, whether it’s making a purchase, signing up for a trial, or finding a discounted product.
iv. Commercial:
Commercial search intent refers to queries where the user is researching a product or service with the intent to make a purchase.
These keywords indicate the user is in the consideration or decision stage of the buyer’s journey.
Some key characteristics of commercial search intent:
- Queries often include words like “best,” “top,” “review,” “compare,” “brand name,” etc. to indicate the user is evaluating options
- Click-through rates on commercial queries are usually high, but bounce rates can be high if the landing page doesn’t match the user’s expectations
- Commercial queries are extremely valuable for SEO and PPC purposes since they indicate a strong purchase intent.
For example, “Best SEO tools 2023” or “iPhone vs. Android comparison.”
In each of these cases, the user is looking to research and compare options before making a purchase decision.
Identifying the search intent behind the keywords you target allows you to create content that directly addresses user needs and improves your chances of ranking higher in search results.
4. Low-Competition Keywords
Low-competition keywords are terms with lower search volumes that are less targeted by competitors. They can be long-tail keywords or more specific variations of higher-volume terms.
Targeting low-competition keywords can be an effective strategy for:
- Gaining visibility in specific niches or sub-topics
- Attracting qualified traffic to your site
- Building authority and relevance in your niche.

While low-competition keywords may not drive as much traffic as high-volume terms, they can still be valuable for building a strong foundation for your website.
By targeting these keywords, you can establish your site as an authority in your niche and gradually expand your keyword targeting to more competitive terms over time.
Keyword Density in SEO
Keyword density is a crucial concept in SEO that refers to the percentage of times a specific keyword appears in a piece of content compared to the total word count.
It is calculated using the formula:
Keyword Density=(Keywords Used/Total Word Count)×100
For example, if a keyword appears 20 times in a 1,000-word article, the keyword density would be 2%.

While keyword density was once a primary factor for ranking in search engines, its significance has diminished as algorithms have evolved.
Modern search engines, particularly Google, focus more on content quality, relevance, and user intent rather than strict keyword frequency.
However, maintaining a keyword density of around 1-2% is still recommended to signal to search engines the content’s focus without resorting to keyword stuffing, which can lead to penalties.
Lastly, while keyword density remains a relevant metric, it should not overshadow the importance of producing high-quality, user-centric content.
Does Keyword Density Matter?
Keyword density is less important for SEO today than it once was. While it can help indicate to search engines what a page is about, modern algorithms prioritize content quality, relevance, and user experience over strict keyword frequency.
Historically, a keyword density of about 1-2% was considered optimal, meaning a keyword should appear once or twice per 100 words.
However, this approach can lead to keyword stuffing, which is penalized by search engines like Google.
Instead, the focus should be on creating valuable content that naturally incorporates keywords without compromising readability.
Google’s algorithms have evolved to understand context and user intent, making keyword density an outdated metric.
As a result, SEO experts recommend concentrating on high-quality, relevant content rather than obsessing over keyword frequency.
Therefore, while keywords remain important, their density is not a primary factor in achieving good search rankings today.
How Many Keywords Should I Use For SEO Content Writing?
Now that you have gotten some knowledge about SEO Keywords and what it is all about. Let’s answer the crucial question; How many keywords should I use for SEO content writing?
When it comes to SEO content writing, the number of keywords you should use can vary based on several factors, including content length, topic relevance, and user intent.
Longer content typically allows for a higher keyword density without appearing spammy. For example, a comprehensive article of 1,500 words can naturally accommodate more keywords than a 300-word blog post.
The relevance of keywords to the topic is crucial. Keywords must accurately reflect the content’s subject matter to meet user expectations and search intent.
Also, understanding user intent is essential in determining keyword usage. Content should be crafted to satisfy the specific needs and questions of users.
Most SEO experts recommend focusing on one primary keyword per page, supplemented by 3-9 secondary keywords.
This approach allows for a targeted strategy while still capturing related search queries. For instance, if your primary keyword is “best travel destinations,” secondary keywords could include “budget travel tips” or “family-friendly vacations”.

Furthermore, the commonly accepted keyword density is 1-2%. This means that for a 1,000-word article, your primary keyword should appear about 10-20 times.
However, it’s essential to use keywords naturally to avoid “keyword stuffing,” which can lead to penalties from search engines.
While you can optimize for multiple keywords, prioritizing high-traffic, low-competition keywords is crucial.
Studies show that pages can rank for an average of 1,890 keywords, but it’s more effective to focus on a few relevant, high-traffic keywords rather than many low-traffic ones.
Therefore, you should aim for one primary keyword and 3-9 related secondary keywords, maintaining a keyword density of 1-2%. This balanced approach will help enhance your content’s visibility and relevance in search engine results.
Is Too Many Keywords Bad for SEO?
Yes of course! Using too many keywords is detrimental to SEO. This practice, known as keyword stuffing, negatively impacts user experience and can lead to penalties from search engines like Google.
Overstuffed content is often unreadable and unhelpful, which drives users away and diminishes the credibility of the website.

Historically, keyword stuffing was a common tactic to manipulate search rankings, but Google’s algorithms have evolved to penalize such practices since the Penguin update in 2012.
This change emphasized the importance of quality content over sheer keyword volume.
Experts recommend maintaining a balanced approach to keyword usage. For instance, targeting one main keyword per page, supplemented by a few related terms, is more effective than cramming multiple keywords into a single piece of content.
Aiming for a keyword density of around 1-2% is often suggested, with 10-20 keywords being optimal for a 1000-word article.
Ultimately, the focus should be on creating valuable, engaging content that naturally incorporates keywords without compromising readability.
