How to Use LSI Keywords

One key aspect of SEO is using LSI keywords in your content.

LSI keywords are terms and phrases that are semantically related to a primary keyword. They are used by search engines to understand the context of a webpage better, thereby improving the relevance and accuracy of search results.

By using related keywords and phrases in your content, you can improve your chances of ranking higher for your target keywords.

So how do you use LSI keywords effectively?

What Are LSI Keywords?

LSI stands for Latent Semantic Indexing. While the term itself might be a bit outdated, the concept is still important for search engine optimization.

In theory, LSI keywords are words and phrases that are related to your main keyword but aren’t necessarily synonyms. Search engines supposedly used LSI to understand the context of a webpage and rank it accordingly.

In reality, search engines don’t explicitly use LSI technology anymore — but they do use semantic analysis, which is similar. This means using relevant keywords throughout your content helps search engines understand what your webpage is about and who it’s relevant to.

Examples of LSI Keywords

Examples of LSI keywords vary depending on the primary keyword or topic. Here are some examples of LSI for popular seed keywords:

LSI keywords for “digital marketing”

  • Online marketing
  • Internet marketing
  • SEO (Search Engine Optimization)
  • Social media marketing
  • Content marketing
  • Email marketing
  • PPC (Pay-Per-Click) advertising
  • Affiliate marketing

LSI keywords for “balanced diet”

  • Nutrition
  • Whole foods
  • Organic food

When you weave LSI keywords naturally into your content, search engines get a better grasp of your page’s purpose, and that can mean higher rankings, increased visibility, and a flood of organic traffic heading your way.

But here’s the key: don’t just stuff your content with every related keyword under the sun. Focus on using LSI keywords that are highly relevant to your main topic and provide value to your readers.

How to Find the Best LSI Keywords for Your Content

While you can quickly ask ChatGPT to come up with a list of LSI keywords for you, nothing beats good old-fashioned data-driven keyword research.

Let me show you how to find the best LSI keywords for your content.

Step 1: Conduct Keyword Research

First things first: keyword research. This is where you’ll uncover the specific terms and phrases your target audience is searching for.

Identify the main keywords central to your topic and then feed them into your favorite keyword tool. Popular choices are Google Keyword Planner, Semrush, Ahrefs, and Moz Keyword Explorer.

You can also use Content at Scale’s in-app keyword research tool which uses the Mangools API to generate hundreds of keywords for your topic, and then write long-form blog posts for each of them in just one click.

As you sift through the results, look for LSI keywords that are highly relevant to your content, have decent search volume, and are easy to rank for (low ranking difficulty). These are the terms you’ll want to prioritize.

Step 2: Use LSI Keyword Tools

To take your keyword research to the next level, you need to explore beyond the basics. That’s where tools like LSI Graph and Answer The Public come in – they’re your secret weapons for finding those all-important semantic keywords.

With your main keyword in hand, these tools go to work generating a list of related terms and questions that help you pinpoint relevant LSI keywords to incorporate into your content.

Step 3: Analyze Search Intent

Another important factor to consider when choosing LSI keywords is search intent. In other words, what is the user looking for when they type a query into Google?

Are they searching for information, a specific product, or a solution to a problem?

Understanding the intent behind the keywords can help you create content that better meets the needs of your audience.

Step 4: Identify Keyword Variations

Finally, don’t forget to look for variations of your main keyword to use as LSI keywords. This can include synonyms, long-tail phrases, and even questions related to your topic.

For example, if your main keyword is “content marketing”, some good LSI keywords might be “content strategy”, “blogging tips”, or “how to create engaging content”.

By incorporating a mix of main keywords and related variations, you can create well-rounded, semantically rich content that both search engines and readers will love.

How to Use LSI Keywords for SEO

You’ve done your research and found a solid list of LSI keywords. Now it’s time to use them in your content. But how do you do it effectively?

Incorporate LSI Keywords Naturally

The most important thing to remember when using LSI keywords is to incorporate them naturally. You never want to force keywords into your content just for the sake of SEO.

Instead, use them where they logically fit and enhance the quality of your writing. A good rule of thumb is to mention your primary keyword a few times throughout the body content where they are relevant. This will help Google understand the context of your content and avoid any issues with keyword stuffing.

Optimize Title Tags and Meta Descriptions

In addition to the body of your content, LSI keywords can also be used in your title tags and meta descriptions. These are the snippets of text that appear in search results and give users a preview of what your page is about.

How to Use LSI Keywords

By including relevant LSI keywords in these elements, you can help search engines and users better understand what your content is about and improve your click-through rates from search results.

Just remember to keep your title tags and meta descriptions concise and compelling. You want to entice users to click through to your site, not overwhelm them with a list of keywords.

Add LSI Keywords to Headings and Subheadings

Another great place to use LSI keywords is in your headings and subheadings. Not only does this help break up your content and make it easier to read, but it also gives search engines important clues about the main topics covered on your page.

When crafting your headings, try to include your main keyword in the H1 tag and use relevant LSI keywords in your H2 and H3 subheadings. This helps create a clear hierarchy and structure for your content.

By using LSI keywords in your headings, you can help Google scan and understand your content more effectively, improving your chances of ranking for relevant search terms.

Balance Keyword Density

Finally, let’s talk about keyword density. This refers to the number of times a keyword appears in relation to the total word count of a page.

While there’s no magic number, a good general guideline is to aim for a keyword density of around 1%. This means if your article is 1,000 words, your primary keyword should appear roughly 10 times.

Remember, the goal is to create valuable, engaging content for your readers first and foremost. Use LSI keywords to enhance the relevance and context of your content, but never sacrifice quality just to get 20 mentions of your main keyword in there.

Common Mistakes to Avoid When Using LSI Keywords

While using LSI keywords can be an SEO game-changer, they can also tank your efforts if done incorrectly.

Let’s explore the top mistakes to avoid to get your strategy back on track.

Overusing LSI Keywords

One of the biggest mistakes people make is overusing their LSI keywords — or keyword stuffing — which is a big no-no in the eyes of Google.

When you’re writing content, it’s essential to strike a balance between providing context with LSI keywords and overwhelming your readers.

Overstuffing your content with keywords can lead to a terrible reading experience and even get you penalized by Google.

Neglecting User Experience

Another mistake is focusing so much on LSI keywords that you forget about the user experience.

Yes, LSI keywords are important for SEO, but they shouldn’t come at the expense of your readers.

Quality trumps quantity when it comes to crafting content. If you’re stuffing your writing with keywords at the expense of clarity and coherence, you’re heading in the wrong direction.

Focusing on Irrelevant Keywords

It’s also important to make sure the LSI keywords you’re using are actually relevant to your content. Just because a keyword is related to your main topic doesn’t mean it belongs in your article.

Stick to closely related keywords and provide additional context. Using irrelevant keywords will only confuse your readers and hurt your on-page SEO.

Ignoring Content Quality

Don’t fall into the trap of thinking LSI keywords are the sole solution to improving your search engine rankings. While they’re crucial, they’re not a magic bullet that’ll skyrocket you to the top.

At the end of the day, the quality of your content is what matters most. Focus on creating high-quality, informative, and engaging content that provides real value to your audience. Use LSI keywords to support and enhance that content, not replace it.

Measuring the Impact of LSI Keywords on Your SEO

So you’ve started using LSI keywords in your content, but how do you know if it’s actually making a difference?

Here are a few ways to measure the impact of LSI keywords on your SEO.

Track Keyword Rankings

One of the first things you should do is track your keyword rankings for both your main keyword and your LSI keywords. Use tools like Google Search Console to monitor your rankings over time.

If you see your rankings improving for your LSI keywords, that’s a good sign that your efforts are paying off.

Keep an eye on your main keyword as well to see if it’s benefiting from the additional context provided by your LSI keywords.

Analyze Traffic and Engagement Metrics

Your website’s traffic and engagement metrics can tell a story. Has the addition of LSI keywords led to a significant increase in organic traffic?

Paying attention to user behavior can reveal a lot about the effectiveness of your LSI keywords.

For instance, if users are spending more time on your site, and bounce rates are decreasing, it could be a sign that your keywords are helping search engines and users better understand your content.

Monitor SERP Features

In addition to tracking your keyword rankings, keep an eye on your visibility in various SERP features like featured snippets and “People Also Ask” boxes.

Conduct Regular Content Audits

To get the most out of your LSI keywords, make regular check-ins a priority. Identify the top-performing pages and dissect the LSI keywords that make them shine.

Tweak your LSI keyword strategy by mining these insights and revamping underperforming content.

Advanced Strategies for Optimizing Your Content with LSI Keywords

If you really want to take your LSI keyword game to the next level, there are a few advanced strategies you can try.

Here’s how to use LSI keywords like a pro:

First, consider using LSI keywords in your internal linking structure. When you link to other pages on your site, use descriptive anchor text that includes relevant LSI keywords. This helps Google understand the context and relationship between your pages.

To give search engines a better grip on your content, try slipping in some schema markup. This semantic trick lets you label the essential details — content type, author, publication date, and more — so search engines can give your page the love it deserves.

If you want to establish yourself as an expert in your field, try grouping related content around your main topics and LSI keywords. This clustering effect can boost your search visibility and cement your authority on the subject.

Now, I know some of this might sound complicated, but don’t worry. Content at Scale makes it easy to build topic clusters through its keyword research tool as it automatically groups related keywords together and creates content around them. All you have to do is add anchor text and internal links.

How to Use LSI Keywords for topic clustering

The secret to SEO success lies in combining forces. LSI keywords are just one piece of the puzzle – you need to amplify their power by optimizing your title tags, structuring your content with header tags, and establishing a robust network of high-quality backlinks.
