For the past month I'm sure you've heard a lot about LSI keywords, about including LSI keywords rather than focusing on keyword density, but I'm sure a lot of you aren't aware of what it even means, and searching for it you found information that didn't make sense. I was asked by a friend to write a short guide on BHW in order to clear some misconceptions about it. I'm no great writer so I'm going to keep it short and pretty basic. LSI - Latent Semantic Indexing They give more relevance to your content. Lets explain it with a short example, which everyone's probably read before. "Apple". It could either mean apple the fruit or apple the company. That's where LSI keywords come into place. The rest of the articles could either contain keywords like "stocks, iphone, ipad, ishit, macbook, microsoft, android" etc. if it's about the company, or keywords like "fruit, nutritious, red, orange, proteins, vitamins" etc. if it's about the fruit. See what the difference is? That's pretty much about it about LSI keywords. They aren't a big deal, most of the articles have them naturally. Now, we come onto the main subject, which I believe is the key to future SEO, and what most people mistakenly refer to as LSI keywords...probably. Unless they were right about LSI keywords and didn't know about Semantically Related Keywords Now THIS is what you need to pay attention to. LSI keywords are shit, this is the real deal. If I have to explain them briefly, I'd call them synonyms. Basically, they're other words which people will search for/include naturally in articles, and are a big indication of whether your articles have been written around a particular keyword. Remember the english lessons, where they told you to use synonyms of words instead of using the same word over and over again? This is just like that. I might be able to explain it better with an example: English Movies, Hollywood movies. Lower Relevancy: British Movies Movies, Films, Pictures. Others with a lower relevancy include: motion pictures, cinema etc. Now, mix and match: English Movies, English Films, English Pictures, Hollywood movies, hollywood films, hollywood pictures. I hope this was a clear enough guide. If you have any questions feel free to post them here and I'll do my best to help you.
