Just like other technology industries, SEO is prone to creating it’s own acronyms, buzzwords and jargon. What are terms that are important vs those that are just empty “Buzzwords”
LSI Keywords
There’s a myth out there that a specific type of sorting/categorization of words called “latent semantic indexing” or ( LSI) keywords that Google sees as relevant to each other. The problem being LSI keywords don’t exist:
There's no such thing as LSI keywords — anyone who's telling you otherwise is mistaken, sorry.

So if someone is pumping up their SEO by talking out their LSI keyword program? That’s a buzzword signaling to run for the hills.
All the buzzwords are useful. For me, there is a typing point. If someone is overusing them, then I don’t want to work with them!
