What are the 3 types of keywords?

There are three types of keywords that you should be aware of when optimizing your website for search engines. These are:

1. Short-tail Keywords: These are one or two-word phrases that are very general. For example: "dog" or "shoes."

2. Long-tail Keywords: These are three or more word phrases that are more specific. For example: "German Shepherd Dog" or "Nike Running Shoes."

3. LSI Keywords: These are Latent Semantic Indexing keywords. They are simply words or phrases that are related to your main keyword. For example: " German Shepherds" or "running shoes."
