LSI keywords:

LSI refers to Latent Semantic Index.LSI keywords are the words that are frequently found together. They share the same context but they are not synonyms. Latent Semantic Indexing keywords helps Google to better understand the meaning of a search query.In the early days if search engine finds one keyword over and over again on the page,it consider it as topic of the page.Thats why Keyword density was important. Now a days google finds the overall topic of the page.So Google uses LSI keywords to go to the overall page's topic.Google crawlers crawl the page to see main keyword in
your title tag, content, image alt text, etc. But along with this Google also crawls ur pages to find LSI keywords.When they found the LSI keywords then only Google relies on the topic of the page.
