LSI (Latent Semantic Indexing) keywords are terms or phrases related to the main keyword that help search engines understand the context and relevance of content. While LSI is a technique used by search engines to identify patterns in word relationships, LSI keywords are words or synonyms that are conceptually related to the primary keyword.
For example, if your main keyword is "dog training," LSI keywords could include "puppy training," "obedience school," "dog behavior," and "training tips." Using LSI keywords in your content helps search engines recognize that the content is relevant to the main keyword, improving the chances of ranking higher for related search queries. These keywords enhance the overall quality and relevancy of the content without overusing the main keyword.
