LSI keywords are commonly used in SEO articles to boost the website's visibility on Google search results. So what is LSI and how can you find them? In this article, On Digitals will explain and guide you on how to optimize LSI keywords to improve your website's ranking.
LSI keywords are words or phrases that are semantically related to the main topic of the article. For example, when writing about “weight loss,” you may include “dieting,” “exercise,” “calorie burning,” “fruits and vegetables,” and more.
LSI keywords use pre-programmed algorithms to identify relationships between words and phrases in text. Let’s take a look at a text string example with the theme “seasons of the year” analyzed in detail below.
Search engines will coordinate the information and suggest the most appropriate results for users.
If an article contains reasonable LSI keywords, it will bring many benefits to both SEO and user experience.
Search engines are where users find and read valuable information and content. Optimizing LSI keywords will make the article more helpful and relevant to the user’s search intent.
As a result, the website will continue to climb the rankings and grow better. If users search for keywords related to the target one, your article will also appear on the search results page.
What users care about is whether the content is sufficient and accurate enough for them to trust it.
Optimizing keywords related to the target keyword and providing additional useful information will increase the user’s interest in the article. Subsequently, they will stay longer on the website. As a result, the credibility of the website is also rated higher than other competitors.
Content containing LSI keywords will definitely connect with the right audience in need. Therefore, once users are interested, they will spend more time researching information and interacting with your article. The bounce rate will also significantly decrease thanks to this.
Optimizing articles containing LSI keywords always brings the best experience for users searching for information. They may not need to search for your target keyword precisely, but they can still receive the useful content of your article through those closely related keywords.
Sometimes the article content inadvertently helps readers solve some problems they are facing.
Search engine is one of the easiest ways to find LSI keywords. You just need to enter the phrase you want to search for in the Google Search box. From that, it will display related keywords for you. For example, when searching for “keyword,” you will get some suggestions as follows:
When you enter a keyword into the Google search box, you will see suggestions for related words or phrases. For example, when entering the keyword “content SEO,” the keywords that may appear include:
If you want to find LSI keywords after seeing the search results, you can scroll down to the bottom. Pay attention to the “Related searches” section. These are useful keyword suggestions that you can refer to in order to find accurate keywords.
In addition, you can also look at the search results that Google returns to get ideas for LSI keywords. For the keyword “weight loss,” you can gather many additional keywords from the search results below:
Google Keyword Planner is also a popular tool for finding LSI keywords. All you need to do is log in to Google Adwords to use Keyword Planner. Choose the “Discover new keywords” option to search for desired keywords.
With Google Keyword Planner, you can start searching with keywords or a website. After entering the word or phrase, just click “Get Results.” The tool will suggest keywords for you to choose from.
LSI Graph allows you to search for keywords for 20 phrases. Simply enter the keyword you want to search for (e.g., “content SEO”) and click “Generate.”
These two tools are also useful for finding LSI keywords easily and conveniently. Keywordtool.io and Ubersuggest will return many new keywords and topics when you perform search operations.
Ahrefs is a tool that many SEO practitioners choose for research and analysis. To find LSI keywords, use the Keywords Explorer feature. Simply enter the keyword in the search box and wait for the results.
Semrush is also a common tool for keyword research by SEO professionals. It works similarly to Ahrefs. In addition, the tool also offers the special feature “SEO Content Template” to optimize search time for users.
Here, common sense means checking your content to see if the ideas in the article are complete. If not, you will need to add LSI keywords. Google always focuses on the correlation between words and entities that humans often implicitly understand.
Therefore, rely on common sense to evaluate your article and add related words if necessary.
In fact, TF-IDF is not directly related to LSI. However, you can sometimes find the necessary keywords or entities for your website.
Knowledge Base refers to informative websites like Wikidata.org or Wikipedia. Here, you will find abundant sources of information and even related phrases for LSI keywords.
Google’s Knowledge Graph collects data mainly from the two Knowledge Bases mentioned above. So, try entering a keyword to see if there is LSI Graph Knowledge data available. These are entities and data points that Google considers to be closely related to the topic of your keyword.
Copy and paste the text from top pages into Google’s Natural Language API. You will find important and relevant entities that you may have missed.
After having your list of keywords, consider how to optimize them in your articles to increase website traffic. You can refer to the following ways:
LSI keywords can also be called “long-tail versions” of the main keywords. For example, if your target keyword is “SEO tool,” then the additional keyword at this point may be “free SEO tool.” If there is a related keyword in the title, it will be optimized for both keywords.
Adding LSI keywords to meta descriptions can make a good impression and attract those who are searching. However, it is important to avoid overstuffing keywords as it can affect readability. Furthermore, Google also does not appreciate this practice.
Alt tags with keywords should be added to all images in the article with appropriate density. Remember that the keyword you add should also be relevant to the content and the image.
Including related keywords in the headings plays a significant role. Google usually pays attention to and evaluates these tags before the content of the article
Additionally, the content can be divided into smaller, more understandable sections using related keywords. In case there are too many of them, carefully select which ones are suitable and which ones are not.
Optimizing keywords for anchor texts can impact website SEO. For example, if other websites link back to yours using a keyword, the ranking of said keyword can be affected.
The primary keyword still plays an important role. Note the following when optimizing primary and LSI keywords:
LSI keywords may be related to the primary keyword, but you need to make sure if they are appropriate within the context. Avoid randomly adding keywords if you do not want your article to appear cluttered and bother readers.
Make sure to do everything at an appropriate level so that the article is good for both Google and users.
Below are some positions to use LSI keywords that you should pay attention to:
It can be observed that a quality article not only requires optimizing content with primary keywords but also reasonable keywords distribution. Hopefully, the article above will help you understand what is LSI keyword, its benefits, and how to optimize it.
