LSI stands for Latent Semantic Intent keywords. LSI keywords are possibly the most controversial topic in SEO.
The concept is that if you put keywords related to the one you are targeting in your content then that will give a boost to your SEO efforts. For example, a page about cats could arguably have LSI keywords such as ‘paws’, ‘whiskers’, ‘zoomies’ etc.
While there is no evidence that this is how Google works, many people still claim that it is a good strategy (and many other people get mad at them for it).
