What is Semantic Indexing?

Posted on

Semantic Indexing, more popularly known as Latent Semantic Indexing or LSI, is something you need to know about if you are at all interested in digital marketing- or to be more specific, SEO. This is the principle governing principle of how search engines like Google analyse their data and web pages, and is imperative to learn about if you want to have an effective SEO strategy. This system relates each word to one another, rather then simply searching for keywords exclusively- which helps it to provide search results which have the right, authentic content and are relevant to the user. 

How does LSI work? 

Latent Semantic Indexing is a system which uses mathematical equations to make correlations between keywords that are being searched for and the website content which is being perused. When search engines analyse separate web pages to understand which are the most common and important keywords it has, they use this system to ignore words which are unimportant. Words like ‘and’, ‘is’ or ‘the’ are used a lot, but do not actually add to the overall content keywords density of the page. This indexing system categorically eliminates all noise and perfunctory words, and brings to the front keywords which are actually related to the search queries. 

Why is important? 

LSI is the only system which effectively works towards bettering the user experience for search engine customers, and ensuring that more relevant and well curated content is shown to them. It works in two stages- firstly, interpreting the user’s intent and determining what exactly it is that he is looking for by analysing the search engine query, and then providing results after careful elimination to ensure that only the most pertinent ones are displayed. It weeds out all the spam, low quality plagiarised content, and second tier pages that are not directly related to the search engine query. It’s importance is three-fold: 

  • It helps the search engine to provide better services and results to its users.
  • Ensures that quality content is given its due by providing it with higher rankings organically
  • Helps the users to have a more satisfying, efficient experience. 

How can you create content tailored for LSI? 

As a part of a rapidly developing digital landscape, it is important for businesses to adapt to the requirements of the online mechanisms. SEO is extremely vital for any business investing in digital marketing, and so it is vital that you refine your content in order to make it more tailored for the Latent Semantic Indexing system. Here are a few strategies you can employ to polish your content: 

  1. Improve your writing style: Research has shown that content which is more conversational and easier to understand in language will be more amiable to LSI. 
  2. Optimisation: Optimise the content on your page in order to not only be at the top of a search engine’s authentic results, but also to earn features like snippets which will make your website more recognisable. 
  3. Data Markup: Use data markup techniques to create backlinking and interrelate several more web pages with your own, so that search engines can analyse them better. 

Latent Semantic Indexing is thus a vital foundation of the entire SEO game, and it is extremely important for any marketer who is exploring digital trends to understand how it works and why it is important for their business.
