Advanced SEO Techniques - Latent Semantic Indexing (LSI)
Earlier in this blog I mentioned abbout SEO basic techniques and today i am going to write about Latent Semantic Indexing (LSI) which is important for people really wanting to master the search engines which are now integrating this technology into their algorithms.
Now I’m not going to start going on about this science but I am going to put it in very easy to understand terms so anyone can grasp it and start using it on their blog giving them an advantage over other bloggers.
LSI is the analysis of words that are related to other words. In search engine terms this means that they will determine what a blog or webpage is about from the words on it. It keeps it way beyond using keywords to tell the search engines what your blog post is about.
For example, if I posted an article about the Ferrari F430 then my keywords would naturally be Ferrari F430. But that’s not always enough. You have to have related keywords in your post that don’t use this same keyphrase. Below is an example of part of my blog post:
Ferrari F430
I’ve just driven many miles to check out getting a new car. The car in question is a stunning Ferrari F430, the predecessor to the Ferrari 360. There was just something about this fine piece of mechanical achievement glowing in it’s trademark Rosso Corsa Red. As I looked around the showroom I could see it stood out from the Lamborghini’s and porches in there with its clearly defined Scuderia logo.
Turning the key to start it up the engine roared and the finely tuned exhaust made me want to sign the check on the spot. You’ll see from the above part of a possible blog post that even though my keyphrase is ‘Ferrari F430’ I don’t overly use it which the search engines don’t like. Instead I only use it in the title and once in the opening (You can use it a few times in the full blog post) but can you see all the related words and phrases. Driven, Car, Ferrari 360, Mechanical, Rosso Corsa Red, Showroom, Lamborghini, Porches, Scuderia, Key, Engine, Tuned Exhaust.
You’ll see that every few words have some relation and this is how search engines know relevant content. They go beyond looking at title tags and stand alone keyhrases. The really great thing for you is that very few people are actually using LSI which gives you the advantage to get your blog posts to the top of the search engines more easily.
You can also see from this example that the content comes across as ‘wrote for the reader’ and not for the search engines. I didn’t use ‘Ferrari’ and ‘F430’ in every sentence which screams SEO content. This is the subtle way you will win in the long term as more search engine rely heavily on LSI as time goes by. There’s plenty more you can find out about LSI and a simple Google search will show plenty of information but above are the basics which you can start using right now.
