Lsigraph is a free to use web platform that provides a very useful tool for finding and using LSI Keywords.

The LSI in LSI Keywords stands for Latent Semantic Indexing. LSI Keywords are keywords which are semantically linked or related to a keyword that you would search for on search engines such as Google, Bing and Yahoo. An LSI keyword is therefore semantically linked to your main keyword, or “seed” keyword.

Google has confirmed, (sort of), that if you increase your usage of LSI keywords on your webpages, those pages will normally be able to rank better in the Search Engine Results Pages (SERPs). I have to admit, it’s a bit of a learning curve and many will not even attempt it but you really should – it is not as difficult as it might seem at first and the rewards could be substantial.

If that sounds a bit like using so called “longtail” keywords then you’re halfway there. Many LSI keywords wil be longtail versions of a seed word – but many won’t.

The difference is that an LSI keyword isn’t just an alternative format for another keyword, it does something much more useful, something search engines like Google need to get right if they are to really be able to deliver the sort of search results that we all want – accurate and relevant ones.

So what is it that LSI keywords hve that ordinary keywords might not have? In short, they demonstrate intent and reflect patterns of use that are not normally obvious. By understanding LSI keywords a search engine can begin to understand the real, deep down interest of the person carrying out the search and tailor the results much more accurately.

So how can you find, and learn how to use LSI keywords? Isn’t it simply a matter of stuffing lots of LSI keywords into your article or blog? The answer to that is no. A Big No!

Fortunately, there is one place on the web where you can go to get the LSI keywords you need and learn how to use them. – for free. The name of the product is Lsigraph and the best bit about it is that it is free – and it really works!

Lsigraph have devised a free to use tool that lets you enter a seed word and then get a list of all the LSI keywords it can find. I realise that this might fall outside the scope of many people but it is worth a little effort getting to understand this technology because Google is certainly taking it seriously and so should you.

Take a look at Lsigraph. It’s a fun interface and, if nothing else, you may improve your knowledge of just how search engines really work. See alternative keyword research tools here.
