What exactly are LSI keywords?
LSI stands for “latent semantic indexing.”
It is a technique used in information retrieval that allows concepts
within the text to be analyzed and relationships between them
identified.
Words have nuances dependent on their context. The word “right”
has a different connotation when paired with “left” than when it is
paired with “wrong.”
Humans can quickly gauge concepts in text. It is harder for
machines to do so.
The ability for machines to understand the context and linking
between entities is fundamental to their understanding of concepts.
LSI is a huge step forward for a machine’s ability to understand text.
What it isn’t is synonyms.
Unfortunately, the field of LSI has been devolved by the SEO
community into the understanding that using words that are similar
or linked thematically will boost rankings for words that aren’t
expressly mentioned in the text.
