What are the different between LSI and long tail keywords?

[simon56]

LSI stands for Latent Semantic Indexing. Latent Semantic Indexing keywords can make your content look more natural to search engines and users. Instead of using the exact phrase repeatedly throughout your text, you can use synonyms and other terms that are related to your content and have the same meaning with your target key phrase.

Long tail keywords are those three and four keyword phrases which are very, very specific to whatever you are selling. You see, whenever a customer uses a highly specific search phrase, they tend to be looking for exactly what they are actually going to buy. Short tail keywords are search phrases with only one or words.
