Search engine optimization (SEO) is constantly changing. Google and other search engines no longer rely solely on exact keyword matching. Algorithms now understand context and relationships. This is where LSI Keywords (Latent Semantic Indexing Keywords) come in – terms that help search engines better interpret content and help users find exactly what they are looking for.
What are LSI Keywords?
Definition: These are keywords and phrases that are thematically and semantically related to the main keyword.
Example: The main word "coffee" → LSIs can be "espresso", "bean roasting", "barista", "coffee science", "caffeine".
Why are LSI Keywords important for SEO?
They improve understanding of content – Google can better evaluate whether a page really addresses a given topic.
They increase relevance – a page can be displayed for a wider range of queries.
They prevent keyword stuffing – the text looks more natural.
They support E-E-A-T – professional, comprehensive content that covers the topic comprehensively.
