Since search engines use keywords as a jumping off point when filtering results, it’s incredibly important to make sure that you know how to use keywords in your content correctly so that your content has a better chance of being found, indexed and ranked.

While there are many opinions on how to use keywords for SEO, I want to provide you with a basic and quick step-by-step guide on how to correctly and safely use keywords in any type of SEO content that you write/post.

How Many Keywords Should You Use On A Page?

When talking about how many keywords to focus on in a page, the answer depends a lot on the keywords you are wanting to use, how related they are to one another, and if they help push the message of the content forward. With the right keyword research, though, it shouldn’t be too hard to come up with a list of 5-10 keywords. That being said, it doesn’t mean you should focus on all 10!

Let’s first discuss the rules of keyword hierarchy. There are 3 main types of keywords for SEO:

1. Primary Keyword
2. Secondary Keywords
3. Additional Keywords

Your primary keyword should be the main focus of the entire article, so the title and ensuing content should reflect that. You can’t really write a good piece of content about 2 separate topics, so only one primary keyword should be used to drive the meat of the content forward.

Secondary keywords are complementary keywords to the primary one, but just slight variations. Usually a main topic will include 3-5 main talking points so using a handful of those secondary keywords makes sense.

Additional keywords are just any other related keywords that are phrased or spelled differently than the first two but mean the same thing. This is a catch-all net to get different variations of your main keywords in there to try and rank for one (or all) of them. Typically, “long-tail” keywords would be included in this category.

So Again, How Many Keywords for SEO?

In most cases, it would be 3-8 total, based on the length of the content. This breaks down into 1 primary keyword, 1-3 secondary keywords and 1-4 additional keywords. This gives you a fighting chance to start ranking for one of them and then further down the line you can even reoptimize your content based on what it’s currently ranking for at that time.

Using more than 8 or so keywords (assuming you don’t have either insanely long content or extremely short content) can come off as spammy. It’s also incredibly hard to naturally incorporate that many keywords for SEO into writing, and really isn’t necessary. What you’ll find is that related keywords will naturally and automatically come up when writing content based around a few really good keywords. Doing more than this usually hurts readability and sticks out like a sore thumb to readers as well as to Google’s page crawlers.

Where to Use Keywords for SEO in Your Content Writing

It’s easy to just say “you need to add keywords for SEO”, but implementing it is a different matter entirely. In fact, there are certain rules and best-practices for adding keywords to a website that can make your SEO efforts much more worthwhile.

You should insert keywords into your content writing using the following steps:

1. Use Keywords in Your Meta Description

This is one of the most basic ways to add keywords for SEO, but it’s often overlooked. The meta description acts as a simple summary to describe what the content is about, so placing the keyword in this summary helps Google to better filter your results. It’s a powerful way to get 1 or 2 of your most important keywords attached to the part of your page that’s directly served up by search engines.

As a refresher, a Meta Description is a 160 character (or 20-25 word) description of what your page is all about. This description is what shows up under a page name and URL when people search for a keyword phrase on search engines. Here is an example of a Meta Description as it appears on the Search Engine Results Pages (SERPs).

How to Use Keywords for SEO in a Meta Description

First, it’s important to have the right tools. If you’re using WordPress, try downloading the Yoast SEO Plugin. This little plugin allows you to quickly optimize your content for both SEO and readability, as well as gives you spots to enter in your Meta Description and SEO Title Tag (see step #2).

Next, when using SEO keywords in a meta description make sure to use the keyword at least once, but no more than twice. Be sure to prioritize a helpful, enticing description over keyword stuffing though, since this is the first thing someone will read before ever visiting your website.

SEO Pro Tip: If you can get a secondary keyword in your meta along with one instance of your primary, you’re killin’ it when it comes to using keywords for SEO.

2. Insert Keywords in Your SEO Title Tag

Keep in mind, I said SEO title, not your main article title. You’ll be optimizing that in just a minute. First things first, let’s get some helpful keyword data in your SEO title tag (also known as a meta title tag). This title tag is similar to the meta description in that it is the name of the page that users will see on search engine results pages (SERPs) when they search a keyword phrase. This title will be clickable from the SERPs and will take the user directly to your page. Here is an example:

How to Use Keywords for SEO in a Meta Title Tag

Similar to meta descriptions, you only have a few characters (about 50-60) to use when writing your SEO title tag. Because of that, you typically want to limit your title tag to just your primary keyword as well as your company name. This is the most concise, user-friendly and SEO-friendly way to execute it.

3. Use Keywords in Your Article Title

If possible, put the keyword in the title of your content. Since Google pairs this title header with your meta description to paint a picture of what your content is about, having the keyword in the title is very helpful as long as it can be used naturally.

If the keyword can’t be used naturally in the title, use a variation that still gets the point of the article across while hitting some of the main words from your keyword phrase. A little is better than nothing!

4. Use Keywords Within the First 200 Words

Many experts believe that Google gives more weight to the first 200 words in your content. The reason why is because usually the first 100-200 words of an article are where a content writer sets up the introduction of what will be discussed. Since most readers only continue on in an article if the introduction is good, it stands to reason that it could be a ranking factor as well.

Where to Use Keywords in an Article Introduction

Knowing that Google scrutinizes the first 200 words of a blog post, it’s very important to make sure that you put your primary keyword within the first sentence or paragraph, if at all possible, without sacrificing the quality of the content. Similarly, you should try to use at least one secondary keyword in the first 200 words as well (though not in the first sentence).

Keep in mind that Google is trying to get an overall picture of what the article is all about, and the way you outline your content really matters. You have to be careful to lead Google to the keywords you want it to focus on and not confuse it when optimizing content for keywords. This means your primary keyword should live in all the most important places, your secondary keywords next, and then any other additional keywords after that. Think of it as a pyramid of usage, with primary keywords at the top.

The focus of the article (and introduction) would be the top of the primary, filled in by secondary and lastly additional keywords to make up an entire keyword structure and strategy for that piece.

5. Insert Keywords Naturally Throughout the Article

In a seemingly SEO-centered digital world, it’s easy to forget that the reader actually comes first. You should never compromise your reader’s ability to be engaged, informed and enlightened by your content because of bad keyword placement. But believe me, it happens all the time. Here is one solution to help you write your keywords more naturally in your content.

Use Stop Words in Awkward Keyword Phrases

One way to help you write keywords more naturally is to utilize “Stop Words” in your keyword writing. These are words that can be added within keyword phrases to help them read more naturally without decreasing their ranking value.

For instance, if you had a keyword phrase you were targeting that reads “plumbing Salt Lake City“, there is literally no way you can insert it into your content exactly as-is without it either looking like a typo or a blatant keyword insertion. The better way to add keywords for SEO is to use a stop word in that phrase. Adding the stop word “in”, would now have it read “plumbing in Salt Lake City”, which can much more easily be inserted into natural writing. Try it out!

You can easily find a list of commonly used stop words you can utilize when adding keywords to your website.

How Many Keywords Should You Put in Your Content?

This is a great question that’s often discussed and argued about among SEOs. The real answer is that it completely depends on the types of keywords you have and the length of your content.

The general rule, however, is you should try to include your primary keyword about once every 100-150 words. So if you’re writing a 1000 word article, inserting the primary keyword around 7-10 times would be appropriate. Also keep in mind that you want to fairly distribute these instances of the keyword throughout the article. You don’t want all 7 instances of your primary keyword in the same 200 word section or you lose the flow of a consistent keyword theme throughout.

Secondary and Additional keywords, however, shouldn’t be in the article more than your primary keyword. Whatever your baseline is for using your primary keyword in your content, decrease by about 25% for secondary and another 25% for additional keywords for SEO. Then you can keep a healthy keyword structure that Google crawlers should easily be able to follow.

6. Use Keywords in the Last 200 Words

Similar to how an introduction of an article is important to keyword rankings because it sets the framework for the content, it could be argued that the conclusion (or last 200 words) is just as important, if not more important. For this reason, try to include your primary keyword again near the last or second-to-last paragraph and include a secondary keyword if possible.

For blog posts, it’s usually good practice to include a call-to-action (or CTA) in the very last paragraph, so if you can fit the primary keyword there, great! If not, get it in that second-to-last paragraph as we talked about above.

7. Use Keywords in Headings (H1s, H2s, H3s, etc)

Headings are a formatting tool that most text editors offer to allow you to help break up your text. From a purely visual standpoint, they are a must-have. Huge chunks of paragraph content with no end in sight are intimidating and often skipped completely. Using headings to break up content allows you to visually move the reader along to the most important points, or the ones they are most interested in.

From an SEO standpoint, headings might be even more important. The HTML tags used to identify H1s, H2s, H3s, etc are also ranking signals for Google to know what’s most important in the content. Adding keywords to headings in content may be the single best way to try and rank for multiple keywords. The more content you have, the more headings you have – so longer content usually ranks better than shorter content.

When a keyword is used in headings, it brings more emphasis to the meaning and importance of the keywords. This helps the search engines to know how relevant those keywords are to your content. Here’s an example of where to find heading formats in a text editor:

How to Add Keywords to Heading 1s (H1s)

Heading 1s, or H1s, are typically reserved just for the main title of the article. If you use multiple H1s in your content, you’re basically asking Google to get confused. Instead, just stick to a single H1 as your article title with your primary keyword included.

How to Use Keywords in Heading 2s (H2s)

Heading 2s, or H2s, are where you can do the bulk of inserting important keywords. H2s are the headings that break up the main sections of your content and usually come into play every couple hundred words. For a 1000 word article, you can plan on around 3-5 of these H2s. this is where you’d want to include the primary keyword again in one of them and reserve the rest for secondary keywords you are targeting.

How to Insert Keywords to Heading 3s (H3s)

Heading 3s, or H3s, are used to help break up and list individual points in the main sections. You might find H3s in the form of numbered lists or clarifying sections to an H2 heading. This is another good place for an instance of the primary, but probably a better spot for secondary keywords and any additional keywords you have.

8. Use Keywords in Anchor Text Links

When a keyword is used as an anchor text link in your content, it implies that there is a place to find even more information regarding that word. This helps to place added emphasis on the keyword and the relevance it has to the content it’s being linked to. So how does that apply to the article you’re currently writing?

Well, it doesn’t. Not exactly. Using keywords as anchor text links in your articles can help OTHER pages on your site. This is also known as creating an internal link structure showing Google where the most important articles are for exact keyword phrases. If you can plan your content accordingly, you know you can use anchor text links of certain keyword phrases to drive the authority of other “pillar” pieces.

SEO Pro Tip: Do NOT use your primary keyword (or variation of it) in anchor text that is linking to another page unless you’ve completely given up hope of ranking for that keyword on that page. Doing this basically tells Google to ignore that keyword on the page you’re working on and to look for it in the page you’re linking to. This is a common mistake that a lot of content marketers make. Instead, find a related topic within your article with an associated keyword that you can link to another page to help improve it’s authority. For any of the main keywords you hope to rank for on the page you’re working on, DO NOT LINK out to other pages using them as the anchor text.

9. Use Keywords in Image Alt-tags

First of all, if you aren’t using images in your content writing then PLEASE do so! I can’t overemphasize how many opportunities you’re missing out on if you aren’t using some kind of visual cue to help educate, engage and inform your readers and prospective clients. Images and content writing (and videos for that matter) are a perfect marriage when it comes to user engagement.

How to Use SEO Keywords in Alt Tags

In terms of keyword usage, using your keywords in an image alt-tag can help it to be shown during image searches. This can help users to be led to your content in a round-about way.

Not only do images help break up the text and give it color, personality and sex appeal, they also can be a great opportunity for you to add keywords for SEO to your website. Take advantage of putting images in your articles and the blessed alt-text you’re allowed to manipulate.

10. Use Keywords in URL

Last, but not least, when it comes to adding keywords to your website to maximize your onsite SEO, you should always try to put your primary keyword in the main page URL of the article you’ve written. If you’ve done the steps above and put your primary keyword in the title of your article, it should be in the URL automatically when you go to publish it. But even if your title is similar to the main keyword but doesn’t include it completely, you should tweak your page URL to include it after the fact.  Here is an example:

There has often been talk among SEOs and content marketers of whether or not it’s necessary to put your primary keyword into your page URL and if it affects rankings. Based on a study we did here at BKA Content, analyzing around 60 posts over a 6 month period, the posts we had with a keyword as a part of the page URL were overwhelmingly ranking for that exact keyword, where posts that didn’t have the targeted keyword in the URL did not. That’s enough evidence for me that it IS effective to include the keyword in the page URL.

SEO Pro Tip: During that same content marketing study we did here at BKA Content, there were some concerns that changing the URL after the fact might hurt any existing rankings we had for that page and that the page might not recover. After changing the URL after the fact (while always including a redirect from the original URL), there was always an immediate drop in tracked rankings in our keyword tracking tool, but it never affected our actual site traffic. In fact, almost every page that had the URL adjusted ended up rebounding in about 3-4 weeks in our keyword tracking tools to rank for more keywords than they were originally.

Track, Refine and Use Different Keywords If Necessary

Last of all, don’t forget that you can go back and re-optimize your posts in a few months once the dust has settled. Give your content about 3 months before you decide to make any real changes, then go and see what keywords it’s ranking for and what’s gained traction, and optimize further from there. If your post is ranking better for a secondary or additional keyword than the initial “primary keyword”, then switch your primary keyword for SEO!

Just be sure to be careful about making massive changes or you could end up capsizing the entire boat. Engage in the art of SEO maintenance and make small changes to optimize keywords and see if the results are favorable. Do this over and over again and you’ll have a really fine-tuned content marketing strategy on your hands.

Conclusion: How to Use Keywords for SEO

• Focus on 3-8 keywords total per article (primary, secondary and additional).
• Add keywords to Meta Descriptions, Meta Title Tags and page URLs.
• Use keywords in title, headers, Alt-Image tags.
• Insert keywords in the first and last paragraphs and evenly throughout.
• If it doesn’t work naturally, don’t use it. Keywords should be relevant and highly applicable to your content, if the word is odd or doesn’t fit, use the correct version of it that makes sense or throw it out.
• While keywords are great, the meat of the content is the most important thing you should focus on. Keyword-riddled content helps nobody and Google will not rank your content unless it helps somebody.
