LSI which stands for Latent Semantic Indexing, refers to a mathematical method used to determine the relationship between terms and concepts in content. In the context of SEO, LSI keywords are keywords that are semantically related to your primary keyword. They aren’t necessarily synonyms but can be closely associated terms or phrases that often co-occur in the same context as your main keyword.
Search engines use LSI keywords to help determine a page’s relevance and the quality of its content. For instance, if you’re writing a piece about “apple,” search engines would look for LSI keywords to determine whether you’re talking about the fruit or the tech company. LSI keywords like “orchard,” “fruit,” and “tree” would indicate the former, while “iPhone,” “Mac,” and “technology” would suggest the latter.
Using LSI keywords in your content can be beneficial for several reasons:
They help search engines understand your content better, which can aid in determining how relevant your page is to a particular search query.
LSI keywords can signal that the content covers a topic comprehensively, increasing the perceived quality.
Relying on LSI keywords can reduce the temptation to stuff your content with the primary keyword. Instead of repeating the main keyword excessively, you can use related terms, making your content read more naturally.
Incorporating LSI keywords is a practice that’s in tune with modern SEO strategies, emphasizing creating high-quality, relevant, and user-friendly content. It’s less about trying to game the system and more about ensuring that your content provides a rich, comprehensive answer to the queries posed by your audience. Tools like LSI Graph and others can assist content creators in finding relevant LSI keywords to include in their content.
