What are Primary Keywords and Secondary Keywords in SEO?

What are primary and secondary keywords in SEO? Most people think that all keywords are created equal, but this is not the case. There is a hierarchy of importance for keywords when it comes to search engine optimization. Primary keywords are the most important, and secondary keywords are less important.

But what determines how important a keyword is? And how do you determine which ones to use for your website or blog? In this post, we will explain what primary and secondary keywords are and how to use them effectively in your SEO strategy.

What are primary keywords in SEO?

Primary keywords are the terms that you want to rank for in search engines, and they should be included in your website content, titles, and tags. They should also be used in your backlinks and social media posts.

In order to choose the right primary keywords, you’ll need to research your audience and find the terms that they’re using to search for businesses like yours. Once you’ve identified a few potential keywords, you can use them in your content to start seeing some results.

However, it’s important to remember that SEO is an ever-changing field, so you’ll need to keep up with the latest trends if you want to maintain your rankings.

How many primary keywords should I use for SEO?

As a general rule of thumb, you should aim to use between 2 and 5 primary keywords for each page on your website. Any more than this, and you run the risk of keyword stuffing, which can damage your search engine rankings. However, fewer than 2 keywords may make it difficult for search engines to properly index your content.

Therefore, 2-5 is generally considered the ideal range. Of course, this will vary depending on the length of your content and the overall density of your keywords. If in doubt, it’s always best to err on the side of caution and use fewer rather than more keywords.

What are secondary keywords in SEO?

Secondary keywords are those that are related to your primary keywords but aren’t as high-priority. They’re still important, though, because they can help you rank for long-tail keywords (phrases that include multiple keywords).

In addition, they can help you attract traffic from people who are searching for similar topics. For example, if you have a blog about cats, your primary keyword might be “cats” and your secondary keyword might be “pet care.” By including both in your content, you’ll be more likely to attract visitors who are interested in what you have to say.

How many secondary keywords are there?

There is no definitive answer to how many secondary keywords can be used on a page, as it will vary depending on the length of the page and the amount of content. However, as a general rule of thumb, it is best to use a maximum of three to five secondary keywords per page. This will ensure that your content is focused and relevant, while also giving you the best chance of ranking for those keywords.

If you have too many secondary keywords, it can diluted your content and make it more difficult to rank for any of them. Therefore, it is important to carefully select the most relevant and important keywords for your page before including them in your content.

Where should secondary keywords be used in an article?

Secondary keywords are usually related to the primary keyword, and they can be used in a number of ways to help improve the search engine optimization (SEO) of an article.

  • One way to use secondary keywords is to include them in the title of the article. This can help to attract more clicks, as well as helping the article to rank higher for the secondary keyword.
  • Another way to use secondary keywords is to include them in the body of the article, preferably in the first and last paragraphs. This helps to show search engines that the article is relevant to the secondary keyword, and it also ensures that readers will see the keyword at least once.
  • Finally, secondary keywords can also be included in the tags and meta descriptions associated with an article. This helps to improve the visibility of the article and make it more likely to be clicked on by users.
  • Ultimately, where you choose to place your secondary keywords will depend on your particular SEO goals. However, using them throughout your article is generally considered to be the best practice.

How to choose primary keywords?

There are a few factors to consider when selecting primary keywords.

  • First, think about the intent of your website. Are you trying to sell products, generate leads, or simply provide information? Depending on your goal, you’ll want to choose keywords that reflect that intent. For example, if you’re selling products, you’ll want to choose keywords that are associated with buying or purchasing.
  • Secondly, consider your target audience. What terms will they be searching for? Once you have a good understanding of your target audience and what they’re looking for, you can start to narrow down your keyword options.
  • Finally, take a look at your competition. What keywords are they targeting? While you don’t want to copy their exact strategy, this can give you some insight into which keywords are most effective in your industry.

By taking the time to research and select the right keywords, you can help ensure that your website is visible to those who are most likely to convert.

How to choose secondary keywords?

When it comes to SEO, keywords are everything. The right keyword can make the difference between a first page ranking and being buried on page 10. But what if you’re not sure which keywords to target? That’s where secondary keywords come in.

Also known as long-tail keywords, secondary keywords are longer, more specific phrases that relate to your primary keyword. For example, if you’re a plumber, your primary keyword might be “plumbing.” But a secondary keyword could be “residential plumbing services.”

While they may not get as much traffic as primary keywords, secondary keywords can be just as valuable because they’re more likely to convert. That’s because someone who searches for a secondary keyword is generally further along in the buying cycle and is therefore more likely to be ready to purchase your product or service.

So how do you choose the right secondary keywords?

  • Start by thinking about what your customers are looking for.
  • What pain points are they trying to solve?
  • What questions do they have?

Once you have a list of potential keywords, use a tool like Google Keyword Planner to see how much search volume each keyword has. Then, prioritize the keywords that are most relevant to your business and have enough volumes.


Primary keywords are the main focus of a website and are what people are likely to type into a search engine to find your site. 

Secondary keywords support the primary keyword by providing related information about the topic, and can be used on pages throughout your website. 

In order to rank well for your primary keyword, you’ll need to make sure that your secondary keywords are included on relevant webpages and that they have enough supporting content.
