    Here are some tools you can use to find LSI keywords for your content:

    Google Autocomplete

    The first feature that can support your LSI keyword research is Google Autocomplete. This is a feature that provides suggested search terms and phrases as the user begins to type their query into the search bar. 

    It is based on Google's algorithm and is designed to help users quickly find the information they are looking for by predicting what they are searching for based on their past searches and the popularity of search terms. Google Autocomplete suggestions are updated in real-time and can change based on the user's location, search history, and other factors. 

    You can collect some LSI keywords to enhance your content.

    Related Search

    The "Related searches" feature in Google can be a valuable tool for finding LSI keywords. Here's how you can use it:

    • Conduct a search: Start by conducting a search on Google using your main keyword or topic.

    • Look at the bottom of the SERP: Scroll to the bottom of the search results page to find the "Searches related to" section.

    • Analyze the related searches: This section will show you a list of related searches based on the terms you entered. These related searches can be potential LSI keywords that you can use in your content.

    • Evaluate the keywords: Evaluate each keyword to determine if it's relevant and useful for your content.

    People Also Ask

    The next SERP feature you can use to conduct LSI keyword research IS PAA (People Also Ask). It is slightly the same as the Related Search as they are both features in Google that provide users with additional information and search suggestions. 

    However, the PAA section displays a list of questions related to the user's search query. These questions are selected by Google's algorithm based on the popularity and relevance of the search terms. When a user clicks on a question, the answer will be displayed, and more related questions will appear, allowing the user to explore further. 

    You can take the list of related questions as your LSI keywords since they have high relevancy to the main topic.
